    Mizuho Mitamura, Satoru Kase, Kiriko Nishiyama-Hirooka, Michiyuki Saito, Susumu Ishida
    BMC ophthalmology, 25, 1, 691, 691, 2025年12月16日, [国際誌]
    英語, 研究論文(学術雑誌), BACKGROUND/AIM: Isolated retinal astrocytic hamartoma (IRAH) is a rare, benign retinal tumor that typically occurs without any clinical comorbidities. The clinical diagnosis of IRAH remains a challenge. This study reported on two patients with IRAH in the juxtapapillary region and evaluated their multimodal imaging findings. CASE REPORT: Case 1 involved a 71-year-old woman who presented with a retinal mass adjacent to the superior optic disc in her right eye. Optical coherence tomography (OCT) of the lesion cross-sections revealed thickening of the inner retinal layer, accompanied by low-reflection spots. Fluorescein angiography (FA) revealed hypofluorescence in the early and late phases. Case 2 involved a 37-year-old woman who presented with a whitish retinal tumor on the nasal optic disc in her left eye. She had a medical history of Vogt-Koyanagi-Harada disease approximately 20 years prior. OCT revealed a highly reflective mass with calcification. FA revealed fluorescein leakage from the tumor during the late phase. Laser speckle flowgraphy (LSFG) revealed cold coloration in both cases, indicating poor blood flow within the tumor. Both patients were diagnosed with IRAH, and no marked changes in the clinical characteristics of the tumors were observed during a follow-up of more than 6 months. CONCLUSION: Multimodal imaging, including LSFG, contributed to the clinical diagnosis of juxtapapillary IRAH, characterized by slow and consistent blood flow, consistent with a stable nature.

    英語, 研究論文(学術雑誌), PURPOSE: Multiple evanescent white dot syndrome (MEWDS) typically resolves spontaneously and is expected to have a favorable visual prognosis. Therefore, the initial manifestations of MEWDS have yet to be well studied. This study aimed to investigate the clinical characteristics of primary and secondary MEWDS patients and evaluate factors responsible for poor visual prognosis. METHODS: The medical records of 36 patients diagnosed with MEWDS between 2004 and 2021 at Hokkaido University Hospital were retrospectively reviewed. The study evaluated patient demographics, clinical characteristics, and multimodal imaging findings. The clinical factors involving final logMAR best-corrected visual acuity (BCVA) were analyzed. In addition, clinical characteristics of secondary MEWDS cases with poor visual prognosis were investigated. RESULTS: Twelve of the 36 patients (33.3%) had active chorioretinal lesions distinct from MEWDS lesions, resulting in a prevalence of secondary MEWDS of 33.3%. Four patients presented with foveal active chorioretinal lesions (11.1%). Retinal atrophy developed in these lesions in all four cases during the follow-up period. Compared to primary MEWDS, secondary MEWDS with foveal involvement of active chorioretinal lesions was associated with significantly worse visual acuity at the initial visit (p = 0.004), and showed a trend toward poorer visual acuity was also observed at the final visit (p = 0.11). In simple linear regression analysis, coexisting foveal involvement of active chorioretinal lesions was significantly associated with worse final logMAR BCVA (p = 0.002). In multiple stepwise linear regression analysis, coexisting foveal involvement (p < 0.001) and male sex (p = 0.03) remained independently associated with poorer visual outcomes. CONCLUSIONS: The presence of foveal active chorioretinal lesions in MEWDS may be associated with poorer visual prognosis. KEY MESSAGE: WHAT IS KNOWN : • Recent reports characterized the clinical aspects of primary and secondary multiple evanescent white dot syndrome (MEWDS), but the visual prognosis of these variants is only slowly unfolding. WHAT IS NEW: • Secondary MEWDS associated with foveal involvement of active chorioretinal lesions had significantly poorer visual acuity at the initial visit and showed a trend toward poorer visual acuity at the final visit compared to primary MEWDS. • In both simple and multiple linear regression analyses, foveal involvement of active chorioretinal lesions was associated with poorer visual outcomes. • The presence of foveal active chorioretinal lesions in MEWDS may be associated with poorer visual prognosis.
  • When ocular surface treatment fails: exploring neuropathic ocular pain in aqueous-deficient dry eye due to Sjögren's syndrome treated with mirogabalin: a case study.
    Yoshiaki Tagawa, Yusuke Aihara, Susumu Ishida
    Immunological medicine, 48, 3, 261, 265, 2025年09月, [国際誌]
    英語, 研究論文(学術雑誌), Dry eye disease can be classified as aqueous-deficient, evaporative and mixed-type. Recently, neuropathic pain has been indicated to be involved in the subjective symptoms of aqueous-deficient dry eye. However, the mechanism underlying neuropathic ocular pain in such patients remains elusive. Here, we present the case of a patient with aqueous-deficient dry eye disease and severe corneal and conjunctival epithelial damage due to Sjögren's syndrome. Despite considerable improvements in ocular surface conditions with local treatments, such as punctal plugs, autologous serum eye drops, rebamipide eye drops, and tacrolimus eye drops, the patient experienced severe ocular pain for two years, which was disproportionate to the objective clinical findings. The pain worsened during the exacerbations of systemic symptom, such as arthritis and interstitial pneumonia, without correlating with the ocular surface findings. The administration of mirogabalin, a neuropathic pain medication, effectively alleviated the patient's subjective ocular pain symptoms. Ocular pain in patients with Sjögren's syndrome is not necessarily linked to an aqueous deficiency or ocular surface findings. It can arise as neuropathic ocular pain due to inflammation spreading to the trigeminal nerve. Given the systemic inflammatory condition and characteristics of the ocular pain, administering neuropathic pain medications should be considered as a treatment option.
  • Severe Aqueous-Deficient Dry Eye Following Herpes Zoster Ophthalmicus With Periocular Inflammation: A Case Series.
    Rina Kanaya, Yoshiaki Tagawa, Kenichi Namba, Mayuko Kimura, Susumu Ishida
    Cureus, 17, 8, e90569, 2025年08月, [国際誌]
    英語, 研究論文(学術雑誌), This series aimed to describe the clinical characteristics and course of severe aqueous-deficient dry eye (ADDE), a condition characterized by tear deficiency and reduced corneal sensation, following ophthalmic herpes zoster infection with periocular inflammation. Four cases of ADDE that developed after ophthalmic herpes zoster infection were retrospectively examined. Clinical data, including disease course, medical history, imaging findings, tear volume assessment, corneal sensitivity testing, and treatment outcomes, were collected. Our patients exhibited severe tear deficiency, significant corneal hypoesthesia, and serious corneal complications, accompanied by persistent ocular pain despite reduced corneal sensation. Imaging studies revealed dacryoadenitis in two cases and suggested severe periocular inflammation in all cases. Persistent superficial punctate keratopathy (SPK) was observed in all patients, with complications including corneal ulcers, perforation, persistent epithelial defects, and filamentary keratitis. Neuropathic pain was believed to contribute to persistent ocular pain. Treatment with topical rebamipide, autologous serum eye drops, punctal plugs, and eyelid closure effectively managed corneal epithelial damage and associated complications. Herpes zoster-induced dacryoadenitis and corneal sensory nerve damage probably contributed to ADDE pathogenesis. Given the potential for severe corneal complications, careful long-term monitoring is crucial in these patients.
  • Unmasking Photophobia and Blepharospasm Mechanisms: The Role of Optic Chiasm and Trigeminal Nerve Compression in a Giant Pituitary Adenoma Case.
    Ayaka Hasegawa, Yoshiaki Tagawa, Yasuhiro Shinmei, Akihiro Shinkai, Susumu Ishida
    Cureus, 17, 8, e91148, 2025年08月, [国際誌]
    英語, 研究論文(学術雑誌), Blepharospasm, characterized by abnormal blinking and sensory hypersensitivity such as photophobia and ocular pain, is thought to arise from pathological sensorimotor integration. We report a rare case of a male teenager with a growth hormone-secreting giant pituitary adenoma compressing both the optic chiasm and bilateral trigeminal nerves. Initially, the patient presented with visual disturbances and bitemporal hemianopia, without photophobia or ocular pain. Following partial tumor resection, which relieved compression of the optic chiasm but not the trigeminal nerves, he developed severe photophobia, deep ocular pain, and bilateral secondary blepharospasm. These symptoms persisted despite pharmacologic interventions, including pregabalin and topical rebamipide. A second surgery, which decompressed the trigeminal nerves, led to the complete resolution of all symptoms. The clinical course suggests that trigeminal nerve compression, particularly of the ophthalmic branch (V1), may induce hypersensitivity states resulting in neuropathic pain, photophobia, and secondary blepharospasm. We hypothesize that initial optic chiasm compression suppressed photophobia by disrupting non-visual photophobia circuits through the suprachiasmatic nuclei to pulvinar nuclei. After decompression, restoration of this pathway unmasked the hypersensitivity induced by ongoing trigeminal compression. The complete resolution of symptoms following trigeminal decompression supports the role of peripheral sensory nerve compression in the pathogenesis of photophobia and secondary blepharospasm. This case provides novel clinical evidence for the interrelationship between the trigeminal and visual pathways in sensorimotor disorders.

  • Morphological Changes in the Saw-Tooth Pattern of Cuticular Drusen Associated with Immune Complex-Mediated Membranous Proliferative Glomerulonephritis Type III: A Case Report
    Takayuki Tanaka, Satoru Kase, Kiriko Nishiyama-Hirooka, Michiyuki Saito, Susumu Ishida
    Case Reports in Ophthalmology, 16, 1, 535, 541, S. Karger AG, 2025年06月25日
    研究論文(学術雑誌), Introduction: Patients with membranoproliferative glomerulonephritis (MPGN) type III may exhibit the saw-tooth pattern of cuticular drusen. This study reports a four-and-a-half-year retrospective time-dependent observation of cuticular drusen associated with immune complex-mediated MPGN type III patients. Case Presentation: A 32-year-old woman was referred for ocular evaluation due to systemic steroids used for nephrotic syndrome caused by immune complex-mediated MPGN type III. She had no ocular symptoms. The initial examination showed that her best-corrected visual acuity (BCVA) was 1.0 oculus uterque (OU). Color fundus photographs revealed pigmentary abnormalities in the macular and perimacular regions OU. Fundus autofluorescence (FAF) images demonstrated numerous tiny dots with a hypoautofluorescent center surrounded by a rim of hyperautofluorescence. Enhanced depth imaging-optical coherence tomography (OCT) revealed triangular morphologic features, represented by a saw-tooth pattern with internal hyporeflectivity. Over 4.5 years, the internal reflectivity of the drusen gradually increased. Moreover, depigmentation and yellow color changes in the macular and perimacular regions worsened, without obvious changes on FAF. Her BCVA remained at 1.0 OU, without new ocular symptoms or cataract progression during the 4.5-year follow-up period. Both eyes had a significant positive correlation between swept-source OCT-based mean internal reflectivity measured by the ImageJ software and the observation period. However, no correlation was found between the estimated glomerular filtration rate (eGFR) and the observation period or between eGFR and mean internal reflectivity. Conclusion: The internal reflectivity of cuticular drusen associated with immune complex-mediated MPGN type III showed time-dependent changes on OCT and worsened depigmentation and yellow color changes in the macular and perimacular regions, independent of renal function.

    Frontiers in Oncology, 15, Frontiers Media SA, 2025年05月15日
    研究論文(学術雑誌), Purpose

    It remains unknown whether choroidal circulation could be altered at the onset of immune checkpoint inhibitor (ICI) uveitis compared with that before ICI treatment. Herein we report a patient with Vogt-Koyanagi-Harada (VKH) disease-like uveitis in the unaffected eye as an immune-related adverse effect (irAE) due to ICIs for metastatic choroidal melanoma who had received enucleation. Moreover, choroidal circulation and choroidal thickness were measured before and after treatment.

    Methods

    A 58-year-old man had a medical history of enucleation in his left eye due to choroidal melanoma 6 years ago. Metastatic lesions in the gastrointestinal tracts and lung were found, and then he received ICIs three times. About 1 month later, he suffered from blurred vision and metamorphopsia in his right eye. Choroidal circulation was evaluated by mean blur rate (MBR), a relative value showing choroidal blood velocity on laser speckle flowgraphy. Central choroidal thickness (CCT) was measured on optical coherence tomography.

    Results

    Since ophthalmic findings revealed VKH-like uveitis, oral prednisolone of 30 mg was given for 2 weeks, which were then tapered. MBR was reduced and CCT increased at the onset of ICI uveitis compared with its baseline and resolution after corticosteroid treatment.

    Conclusions

    Choroidal circulation was disrupted, possibly due to ICI-induced autoinflammatory reaction to the choroid, which was managed by corticosteroid treatment. The combination of MBR and CCT could be a useful biomarker for managing the patients with VKH-like uveitis by ICIs.

    Michiyuki Saito, Mizuho Mitamura, Yuki Ito, Hiroaki Endo, Satoshi Katsuta, Susumu Ishida
    Journal of Clinical Medicine, 14, 9, 3245, 3245, MDPI AG, 2025年05月07日
    研究論文(学術雑誌), Background/Objectives: To investigate the impact of pachychoroid on the clinical features of neovascular age-related macular degeneration (nAMD) in Japan using the deep learning-based Hokkaido University pachychoroid index (HUPI), which has a high discriminative ability for pachychoroid. Methods: This retrospective observational study examined 124 eyes of 111 treatment-naïve nAMD patients, including 44 eyes with type 1 macular neovascularization (MNV), 26 eyes with type 2 MNV, and 54 eyes with polypoidal choroidal vasculopathy (PCV). HUPI was calculated for each eye from EDI-OCT choroidal images using our modified LeNet that had learned the image patterns of pachychoroid. Differences in HUPI between nAMD types and inter-relationships between nAMD parameters, including HUPI, were evaluated. Results: The mean HUPI was 0.53 ± 0.30 for type 1 MNV, 0.33 ± 0.23 for type 2 MNV, and 0.61 ± 0.3 for PCV, with significant differences between any two of the three groups (p < 0.05, for each). Round-robin multiple regression analysis for nAMD parameters showed the close associations of the HUPI with choroidal vascular hyperpermeability (CVH) and subretinal fluid (SRF) (p = 0.017 and p < 0.001 for each) and the clear division of nAMD parameters into the following two groups: one including intraretinal fluid and type 1 and type 2 MNV and the other including SRF, CVH, polypoidal lesions, and HUPI. Conclusions: HUPI revealed that eyes with type 1 MNV and PCV had more pachychoroid-like features than eyes with type 2 MNV. HUPI was tightly associated with CVH and SRF but not MNV per se in nAMD parameters, reinforcing the pathoetiological concept of differentiating pachychoroid from typical nAMD.

    Cancer Diagnosis & Prognosis, 5, 3, 404, 409, International Institute of Anticancer Research, 2025年05月03日
    研究論文(学術雑誌), Background/Aim:Dedifferentiated liposarcoma (DDLS) is a rare but aggressive subtype of liposarcoma that arises in soft tissues. In orbital liposarcoma, malignant transformation from well-differentiated to DDLS typically takes at least a year. We herein report a case of a young female with an aggressive DDLS, that developed from an orbital lipoma within one year.Case Report:A 25-year-old woman presented with left upper eyelid swelling. MRI revealed abnormal adipose tissue in the medial orbit. The excised tissue was diagnosed as an orbital lipoma. The eyelid swelling recurred three months later, and the orbital tumor enlarged. An additional resection was performed, which again revealed a lipoma without malignant features. Three months later, the swelling worsened, and tumor resection confirmed well differentiated liposarcoma with a Ki-67 labeling index of 10%. Two months later, CT imaging depicted calcified lesions within the tumor. The patient subsequently underwent orbital exenteration followed by proton beam radiation. Histopathological examination of the exenterated tissue revealed DDLS with extensive osseous components. The Ki-67 labeling index exceeded 50%.Conclusion:Ocular oncologists should pay attention to the possibility of rapid malignant transformation in DDLS in primary orbital liposarcoma.

  • Differences in Artificial Intelligence-Based Macular Fluid Parameters Between Clinical Stages of Diabetic Macular Edema and Their Relationship with Visual Acuity
    Mizuho Mitamura, Michiyuki Saito, Kiriko Hirooka, Zhenyu Dong, Ryo Ando, Satoru Kase, Susumu Ishida
    Journal of Clinical Medicine, 14, 3, 1007, 1007, MDPI AG, 2025年02月05日
    研究論文(学術雑誌), Background/Objectives: The aim of this study was to determine artificial intelligence-based macular fluid (MF) parameters in diabetic macular edema (DME) with optical coherence tomography (OCT) and examine stage-by-stage differences in MF parameters and their relationship with best-corrected visual acuity (BCVA). Methods: This study enrolled 104 eyes with treatment-naïve DME. Intraretinal fluid (IRF) and subretinal fluid (SRF) were detected in horizontal OCT images based on the “Hokkaido University MF segmentation model” when DME was first observed together with BCVA testing. The MF area, the mean brightness, and the variance of brightness were compared between mild or moderate non-proliferative diabetic retinopathy (mNPDR, n = 33), severe NPDR (sNPDR, n = 52), and PDR eyes (n = 19). Correlations between logMAR BCVA and MF parameters were also examined. Results: All the MF parameters tended to increase with DR stages. Especially, the mean brightness of IRF was significantly greater in PDR than in mNPDR. The variance of brightness of IRF increased in sNPDR compared to mNPDR, whereas that of SRF increased in PDR compared to sNPDR. LogMAR BCVA showed positive correlations with MF areas and the variance of brightness of SRF. Conclusions: The qualitative and quantitative MF parameters may be useful for better understanding DME pathogenesis according to DR progression.

    International journal of ophthalmology, 18, 12, 2385, 2389, 2025年, [国際誌]
    英語, 研究論文(学術雑誌), AIM: To evaluate the clinical features of primary lacrimal gland pleomorphic adenoma (LGPA). METHODS: This was a 2-center, retrospective, observational study of primary LGPA patients who underwent tumor resection. Ophthalmic examinations and orbital computed tomography (CT) and/or magnetic resonance imaging (MRI) were performed. RESULTS: Totally 18 patients (10 males and 8 females, mean age 56.3±13.8y) were enrolled. Initial symptoms were unilateral proptosis in 8 patients, diplopia in 3 patients, and pressure sensation and no chief complaint in 2 patients each. The best-corrected visual acuity of the affected eye was 0.26±0.44 logMAR, and the intraocular pressure (IOP) of the affected and healthy eyes was 20.1±9.9 and 15.8±4.3 mm Hg, respectively. The difference in degree of proptosis between the affected and healthy eyes was 4.1±2.2 mm based on the Hertel ocular protrusion meter. One case had a history of breast cancer. Seventeen of 18 patients with an orbital lacrimal gland origin underwent total tumor excision by anterior/lateral orbitotomy. CONCLUSION: Orbital LGPA can complicate IOP elevation, and require total tumor excision by orbitotomy. In rare cases, systemic malignancy may complicate LGPA, and in such cases total removal of the lacrimal gland tumor should be considered at the initial surgery.

    Journal of Diabetes Research, 2025, 1, Wiley, 2025年01月
    研究論文(学術雑誌), Purpose: The Spontaneously Diabetic Torii (SDT) fatty rat is an animal model of obese Type 2 diabetes. We previously reported that the SDT fatty rats develop diabetic cataracts. This study aimed to elucidate early diabetic changes in the retina of the SDT fatty rats.

    Materials and Methods: The retinal thickness, capillary diameter, and pericyte/endothelial cell (P/E) ratio were assessed in the male SDT fatty rats and Sprague–Dawley (SD) rats at 24 weeks of age. Immunostaining was performed to assess the intercellular adhesion molecule‐1 (ICAM‐1) and vascular cell adhesion molecule‐1 (VCAM‐1) levels in the retinal capillaries. DNA microarray analysis was performed to detect inflammation‐associated molecules in the retina of the SDT fatty rats. Real‐time PCR and Magnetic Luminex Assay were performed to validate the results.

    Results: The retinal thickness in the SDT fatty rats was significantly greater than that in SD rats. The capillary diameter in the retina of the SDT fatty rats was significantly higher than that of SD rats. The P/E ratio in the SDT fatty rats was significantly lower than that in SD rats. ICAM‐1 and VCAM‐1 were observed in the retinal vessels of the SDT fatty rats. The levels of mRNA and protein of Mcp1, Il1b, Icam1, and Tnf were upregulated in the retinal tissues of the 24‐week‐old SDT fatty rats.

    Conclusions: Our study demonstrated that the SDT fatty rats exhibited early diabetic retinal changes, suggesting that the SDT fatty rats may be useful in research on the pathogenesis of early human diabetic retinopathy.

    BMC ophthalmology, 24, 1, 549, 549, 2024年12月27日, [国際誌]
    英語, 研究論文(学術雑誌), BACKGROUND/AIM: Mucosa-associated lymphoid tissue (MALT) lymphomas occur in not only the ocular adnexa, but rarely in the sclera or uvea. Histopathological confirmation contributes to a better understanding of the pathogenesis and treatment. We report a case of uveoscleral MALT lymphoma with angle-closure glaucoma. CASE REPORT: A 73-year-old man was referred to our hospital for a detailed examination of a choroidal mass oculus sinister (OS). At the initial examination, best-corrected visual acuity (BCVA) was 0.4 OS, intraocular pressure was 37 mmHg OS, the left eye had a narrow angle with anterior chamber inflammation. Optical coherence tomography (OCT) showed marked choroidal elevation. Anterior segment OCT showed tumor invasion into the inferior angle and ultrasound B-mode echography demonstrated choroidal thickening and a banded hypoechoic area posterior to the eye. Magnetic resonance imaging showed isointensity in the tumor on heterogeneous enhancement on gadolinium contrast-T1WI. A tumor biopsy of the left sclera was performed one month after the initial visit. Based on pathological findings, he was diagnosed with uveoscleral MALT lymphoma. Two months after the initial visit, left eye irradiation was performed. Nine months after the initial visit, the tumor was in remission with open angle. CONCLUSION: Angle-closure glaucoma caused by the uveoscleral MALT lymphoma was treated with radiotherapy, leading to IOP normalization as well as tumor remission.
  • A Case of Metastatic Iris Tumor from Adenocarcinoma of the Cecum Diagnosed by Combined Tumor Markers in Aqueous Humor and Fine Needle Aspiration Cytology

    Case Reports in Oncology, 18, 1, 29, 34, S. Karger AG, 2024年12月24日
    研究論文(学術雑誌), Introduction: The diagnosis of metastatic iris tumor is made by a fine-needle aspiration biopsy of part of the solid component of the tumor and tumor cells seeded in the anterior chamber; however, sometimes the diagnosis is not made due to insufficient sample volumes. We report a case of metastatic iris tumor in which measurement of tumor marker levels in the aqueous humor together with fine needle aspiration cytology contributed to the diagnosis. Case Report: An 80-year-old Japanese woman was referred to our hospital because of an iris mass. Six months before the initial visit, the patient was diagnosed with adenocarcinoma of the cecum. Slit-lamp microscopy revealed an elevated iris mass. Fine-needle aspiration cytology suggested adenocarcinoma. The carcinoembryonic antigen (CEA) level in the anterior chamber was 5,716.1 ng/mL, and serum CEA level measured on the same day were 678.5 ng/mL. These data indicated CEA levels synchronously elevated in both anterior chamber and serum. Based on aspiration cytology and high CEA levels of anterior chamber, she was diagnosed with metastatic iris tumor derived from adenocarcinoma of the cecum. One month after the initial visit, right eye irradiation was performed for metastatic iris tumor. Conclusions: Measurement of tumor marker levels in the aqueous humor, together with fine needle aspiration cytology of the tumor, contributes to the diagnosis of metastatic iris tumors.

    Yuka Suimon, Satoru Kase, Rumiko Kinoshita, Susumu Ishida
    Canadian journal of ophthalmology. Journal canadien d'ophtalmologie, 59, 5, e501-e509, 2024年10月, [国際誌]
    英語, 研究論文(学術雑誌), OBJECTIVE: Clinicopathologic features of patients with limited-stage mucosa-associated lymphoid tissue (MALT) lymphoma refractory to radiotherapy have not been fully elucidated. This study aimed to elucidate clinicopathologic features of localized conjunctival MALT lymphoma concerning radiosensitivity by analyzing cell proliferation and expression of mismatch repair proteins. METHODS: We enrolled 26 patients with localized conjunctival MALT lymphoma treated with radiotherapy from November 2007 to March 2020. Monoclonal immunoglobulin H gene rearrangement was tested in addition to histopathologic evaluation. Thirty-six specimens were immunostained with antibodies to Ki-67 and MutL protein homologue 1 (MLH1), MutS protein homologue 2 (MSH2), and MutS protein homologue 6 (MSH6). Positive rates under a high-power field at a hot spot were counted manually. RESULTS: After radiotherapy, 21 patients showed clinical disappearance of the tumour without recurrence (effective group). Three patients showed temporary disappearance of the tumour, which later recurred (relapse group). Two patients did not show disappearance of the tumour (ineffective group). The 2 ineffective patients were young, had bilateral lesions, and received x-ray beam therapy. The mean positive rates of Ki-67, MLH1, MSH2, and MSH6 were higher in tumours with complete remission (CR) than in those without CR (23.4% ± 4.0% and 18.7% ± 4.7%, 14.7% ± 2.3% and 7.1% ± 3.7%, 23.9% ± 4.7% and 14.4% ± 5.2%, and 11.5% ± 3.2% and 5.4% ± 2.2%; p > 0.05 for each, respectively). CONCLUSIONS: A few patients could not achieve CR following radiotherapy, whereas there were no significant differences in proliferation activity and mismatch repair proteins between tumours with and without CR.

    Journal of Clinical Medicine, 13, 17, 5271, 5271, MDPI AG, 2024年09月05日
    研究論文(学術雑誌), Background/Objectives: The purpose of this study was to analyze relevant areas in acute-stage fluorescein angiography (FA) images, predicting the long-term visual prognosis of branch retinal vein occlusion (BRVO) based on gradient-weighted class activation mapping (Grad-CAM). Methods: This retrospective observational study included 136 eyes with BRVO that were followed up for more than a year post-FA. Cropped grayscale images centered on the fovea (200 × 200 pixels) were manually pre-processed from early-phase FA at the acute phase. Pairs of the cropped FA images and the best-corrected visual acuity (BCVA) in remission at least one year post-FA were used to train a 38-layer ResNet with five-fold cross-validation. Correlations between the ResNet-predicted and true (actually measured) logMAR BCVAs in remission, and between the foveal avascular zone (FAZ) area measured by ImageJ (version 1.52r) from FA images and true logMAR BCVA in remission were evaluated. The heat maps generated by Grad-CAM were evaluated to determine which areas were consumed as computational resources for BCVA prediction. Results: The correlation coefficient between the predicted and true logMAR BCVAs in remission was 0.47, and that between the acute-stage FAZ area and true logMAR BCVA in remission was 0.42 (p < 0.0001 for both). The Grad-CAM-generated heat maps showed that retinal vessels adjacent to the FAZ and the FAZ per se had high selectivity (95.7% and 62.2%, respectively). Conclusions: The Grad-CAM-based analysis demonstrated FAZ-neighboring vessels as the most relevant predictor for the long-term visual prognosis of BRVO.

  • Giant conjunctival melanoma with rich vascularization causing persistent bleeding.
    Satoru Kase, Yuka Suimon, Mizuho Mitamura, Hiromi Kanno-Okada, Susumu Ishida
    Molecular and clinical oncology, 21, 2, 53, 53, 2024年08月, [国際誌]
    英語, 研究論文(学術雑誌), The present study reported a rare case of persistent bleeding caused by conjunctival melanoma containing abundant vascular channels. A 44-year-old Japanese woman presented with a left upper eyelid nodule in February 2023. A pigmented conjunctival mass was present in the upper palpebral conjunctiva. Enhanced computed tomography demonstrated marked enhancement in the left eyelid in the artery phase, indicating hemangioma. The patient suffered blunt trauma to the face in May 2023 and continuous bleeding occurred. Doctors in the emergency room attempted hemostasis by diathermy and suture, but the bleeding could not be stopped. The patient eventually underwent emergent orbital exenteration of the left eye. At high magnification of the histology sample of the bleeding site, small-to-large vascular channels with various vascular lumens made up of endothelial cells within the conjunctival melanoma tissue could be observed. The tumor cells were positive for SOX10, Melan A, S100 and HMB45. We herein propose a novel variant of conjunctival melanoma with rich vascularization, clinically causing persistent bleeding.

    英語, 研究論文(学術雑誌), OBJECTIVE: To analyze the anatomical choroidal vascular layers in topical treatment-naïve diabetic retinopathy (DR) eyes. DESIGN: A retrospective, clinical case-control study. METHODS: A total of 328 eyes from 228 patients with treatment-naive DR and 192 eyes matched for axial length from 174 healthy controls were enrolled in the study. Choroidal structure was quantitatively analyzed using enhanced depth imaging optical coherence tomography (EDI-OCT). Each choroidal vascular layer was divided into the choriocapillaris, Sattler's layer, and Haller's layer, and then the choroidal area (CA), luminal area (LA), stromal area (SA), and central choroidal thickness (CCT) were calculated using binarization techniques. The ratio of LA to CA was defined as the L/C ratio. RESULTS: In the choriocapillaris, CA was significantly lower in the mild/moderate non-proliferative DR (mNPDR) group than in the control group, and SA was significantly higher in all DR groups (each P < 0.01). The L/C ratio was significantly lower in all DR groups than controls (P < 0.01). In Sattler's layer, CA, LA, and SA were significantly higher in the severe NPDR (sNPDR) and PDR groups than in the control group (P < 0.01). In Haller's layer, the L/C ratio was significantly high among the PDR groups (P < 0.05). CONCLUSIONS: The choroidal parameters of DR patients by the binarization method were associated with the stage of DR, in which the choriocapillaris lumen decreased in all the DR stages. The expansion of CA seen in more advanced DR eyes mainly resulted from changes in the Sattler's and Haller's layers.

    英語, PURPOSE: Choroidal melanocytoma is a rare benign melanocytic tumor. We report a case of choroidal melanocytoma that was definitively diagnosed by histopathological findings after local resection. OBSERVATION: A 71-year-old female complained of blurred vision in her left eye. Her best-corrected visual acuity (BCVA) was 1.0. A dark-brown elevated lesion, measuring 5 papilla-diameter was found in the periphery of the fundus in her left eye. The mass showed hyperfluorescence on fluorescein angiography, early hypofluorescence and late hyperfluorescence on indocyanine green angiography. B-mode echography indicated the mass was originated from the choroid. Orbital magnetic resonance imaging showed isointense signal intensity on T1-weighted images (WI) and hypointense signal intensity on T2-WI, and poor Gadolinium enhancement on T1WI. The tumor was suspected to be melanocytoma, but it was difficult to differentiate from malignant melanoma. Transscleral tumor resection combined with 25-gauge vitrectomy was performed. Histopathological examinations led to the diagnosis of choroidal melanocytoma. Two years after local resection, her BCVA was 1.0 with no tumor recurrence. CONCLUSIONS/IMPORTANCE: Local resection was useful as a diagnostic treatment for choroidal tumors confined to the periphery of the fundus that were difficult to clinically differentiate from malignant melanoma.

    Scientific reports, 14, 1, 2527, 2527, 2024年01月30日, [国際誌]
    英語, 研究論文(学術雑誌), To quantify the choroidal structures of normal eyes by optical coherence tomography (OCT)-based binarization and evaluate the relationships among age, refractive power, and ocular axial length. This was a retrospective observational study. One hundred and eighty nine eyes of 189 subjects without ocular diseases were examined by enhanced depth imaging (EDI)-OCT. A choroidal OCT horizontal image with a width of 1500 μm centered on the fovea was binarized. The lumen, stroma, and total choroidal area in the choriocapillaris (CC), Sattler's layer (SL), and Haller's layer (HL) were measured, and the ratio of the luminal area to total choroidal area (L/C ratio) was calculated. Multiple regression analysis was performed for choroidal parameters in each choroidal layer and for age, refractive power, and ocular axial length. Multiple regression analysis showed that an older age was significantly correlated with a lower choroidal area and the L/C ratio in all choroidal layers (each P < 0.05). A Long axial length was significantly associated with lower SL and HL (P < 0.05), but not with refractive power. In the choroid of normal eyes, age-related decreases in the choroidal area and L/C ratio were associated with all choroidal layers, and elongation of the axial length was associated with thinning of SL and HL.

    Mizuho Mitamura, Satoru Kase, Susumu Ishida
    Cancer diagnosis & prognosis, 4, 4, 539, 543, 2024年, [国際誌]
    英語, 研究論文(学術雑誌), BACKGROUND/AIM: Intraocular metastases of systemic cancer are most frequently located in the choroid, followed by the iris and ciliary body, while retinal metastases are extremely rare. Here we present a case of retinal metastasis and analyze multimodal imaging. CASE REPORT: A 66-year-old woman with a medical history of breast cancer 5 years earlier was referred to our Department struggling with blurry vision in her right eye. At initial examination, her best-corrected visual acuity (BCVA) was 1.0 oculus dexter (OD). Fundus examination revealed a yellowish elevated lesion with irregular surface, measuring 2 papillary diameters, along with serous retinal detachment (SRD) on the temporal side of the optic disc. Optical coherence tomography showed SRD with an isointense nodule extending across all retinal layers. Fluorescein angiography showed hyperfluorescence and vigorous fluorescence leakage inside the tumor in the early and late phases, respectively. Indocyanine green angiography depicted feeder and drainage vessels within the mass. Laser speckle flowgraphy (LSFG) showed a cold signal inside the tumor. Based on these clinical findings, the mass was diagnosed as a retinal metastasis. Eight days after the initial visit, the patient underwent external beam radiation to the right eye. One month after the initial diagnosis, her BCVA was 0.7 OD, the tumor was localized, and SRD had decreased. LSFG indicated vascular remodeling with marginally warmer signals in the tumor. CONCLUSION: LSFG of the retinal metastasis showed a cold signal, suggesting low tumor blood flow velocity and that the tumor may have grown slowly. LSFG findings are likely to play a supportive role in clinical diagnosis and contribute to better understanding of pathogenesis in juxtapapillary tumors.

    International journal of ophthalmology, 17, 7, 1262, 1266, 2024年, [国際誌]
    英語, 研究論文(学術雑誌), AIM: To introduce a novel surgical technique using a Z-shaped incision without epithelial resection in ophthalmic pterygia. METHODS: This was a prospective study. During pterygium surgery, all proliferative tissues were separated from the cornea and conjunctiva without resection of the tissues. The unaffected conjunctiva was incised in a Z-shape. The upper (or lower) conjunctival flap was sutured to the lower (or upper) normal conjunctiva on the limbal sclera, while the proliferative tissue was sutured to the upper conjunctiva (or lower) near the fornix. RESULTS: Ten patients with pterygia were eligible for this study. Eight patients with primary pterygia and 2 with recurrent pterygia were included. The age of patients at surgery ranged from 47 to 90y (average: 71.9y). Five patients each showed right and left-sided pterygia. The postoperative follow-up periods were from 8 to 78mo (average: 25.0mo). The surgery was successfully conducted and wounds were favorably reconstructed in all patients. The proliferative tissues sutured to the normal conjunctiva showed palor and attenuated neovessles, and never showed re-growth after surgery. Nine patients did not show recerrence. Recerrent pterygium was noted in 1 patient, but additional treatments were not required. CONCLUSION: The procedure involves the reconstruction of pterygial tissue and normal conjunctiva using a Z-shaped incision. The scleral limbal wound can be covered with non-affected conjunctiva without any excision of conjunctival epithelia in patients with primary or recurrent pterygia.

    Biomedical reports, 20, 1, 13, 13, 2024年01月, [国際誌]
    英語, The present study describes the case of a patient with refractory diabetic cystoid macular edema who underwent vitrectomy with en bloc removal of the cystoid lesion component. The current study also performed histopathological and immunohistochemical analyses of the cystoid lesion component to assess fibrin/fibrinogen and advanced glycation end-products (AGEs) immunoreactivity. A 69-year-old Japanese man presented with visual loss in the left eye due to residual cystoid macular edema (CME) refractory to anti-vascular endothelial growth factor therapy. Best-corrected visual acuity was 1.2 in the right eye (OD) and 0.5 in the left eye (OS). Fundus examination showed dot hemorrhages and hard exudates in the peri-macular region with pan-retinal photocoagulation scars in both eye. Swept-source optical coherence tomography revealed CME with slight hyperreflectivity in the cyst OS. A total of 3 months after the initial visit, pars plana vitrectomy was performed, and the translucent solidified component within the cystoid lesion was isolated. Histopathologically, the excised component was elliptical in shape, measuring 0.7x0.4 mm and exhibited homogeneous eosinophilic material without cellular components. No membranous structure was observed surrounding the component. Immunohistochemistry demonstrated that the tissue was positive for fibrin/fibrinogen and weakly positive for AGEs, but was negative for glial fibrillary acidic protein, type 1 collagen and receptor for AGEs. To the best of our knowledge, the present case report is the first to histopathologically examine the contents of refractory CME, and to immunohistochemically demonstrate that fibrin in diabetic CME may be post-translationally modified by AGEs. These results suggested that fibrin in CME may escape degradation by plasmin due to post-translational modifications.

    Retinal cases & brief reports, 17, 6, 723, 727, 2023年11月01日, [国際誌]
    英語, 研究論文(学術雑誌), PURPOSE: Retinal racemose hemangioma is a rare, unilateral, nonhereditary, arteriovenous malformation characterized by the appearance of dilated and tortuous retinal vessels. Retinal racemose hemangioma can develop complications associated with retinal ischemia, such as vitreous hemorrhage, retinal vein occlusion, and neovascular glaucoma. Here, a case of retinal racemose hemangioma with retinal hypoperfusion detected by wide-field swept-source optical coherence tomographic angiography was reported, which was not unambiguously illustrated by fluorescein angiography. METHODS: Case report. RESULTS: A 57-year-old woman was referred to our hospital for the evaluation of severe retinal vascular tortuosity, dilation, and retinal hemorrhages in the left eye. Fundus examination revealed arteriovenous communications temporal to the fovea and multiple microaneurysms surrounded by retinal hemorrhages at the midperipheral temporal fundus. In fluorescein angiography, multiple hyperfluorescent lesions with leakage corresponding to microaneurysms were observed in the temporal and lower midperipheral areas; however, nonperfused areas were apparently absent. By contrast, wide-field optical coherence tomographic angiography clearly showed low-density retinal capillaries in the superotemporal quadrant in comparison with those in the inferotemporal quadrant. CONCLUSION: Wide-field optical coherence tomographic angiography detected sparse retinal capillaries, which were not well illustrated by fluorescein angiography, in a patient with retinal racemose hemangioma. This indicates the presence of low-grade retinal hypoperfusion caused by altered retinal hemodynamics, potentially leading to ischemia-related retinal disorders during a prolonged course, in patients with clinically quiescent retinal racemose hemangioma.

    英語, 研究論文(学術雑誌), BACKGROUND: Tubulointerstitial nephritis and uveitis (TINU) syndrome is an uveits characterized by complications of idiopathic acute tubulointerstitial nephritis, and most cases present only anterior uveitis. We report a case of TINU syndrome in which the presence of choroiditis was revealed by multimodal imaging. CASE PRESENTATION: A 12-year-old male visited our hospital with a 6-day history of ocular pain and hyperemia. Conjunctival and ciliary injections, 1 + flare and 3 + cells of anterior chamber inflammation with mutton fat keratic precipitates were observed in both eyes (OU), together with redness and swelling of the optic disc OU. Laboratory tests showed slightly high levels of soluble IL-2R and serum β2 microglobulin and markedly high levels of urinary β2 microglobulin. The diagnosis of probable TINU syndrome was established on the basis of bilateral uveitis and urinalysis results in accordance with a clinical criteria of tubulointerstitial nephritis. With treatment with oral prednisolone (PSL) at 20 mg/day, ocular findings improved, and the dose of PSL was gradually reduced and withdrawn 6 months later. However, 1 month later from the withdrawal, ocular inflammation recurred with the presence of retinal exudates and snowball vitreous opacities in the peripheral retina OU. Fluorescein angiography showed leakages from peripheral retinal vessels and staining corresponding to retinal exudates. Indocyanine green angiography showed hypofluorescent dots scattered over the ocular fundus. Optical coherence tomography revealed the presence of choroidal thickening. Laser speckle flowgraphy color map showed a relatively cooler color. Findings from these multimodal images indicated the presence of subclinical choroiditis; therefore, oral PSL was administered again, and ocular inflammatory findings were improved. CONCLUSIONS: TINU syndrome can exhibit subclinical choroiditis detected with multimodal imaging. Further studies are necessary to determine the frequency of subclinical choroiditis in TINU syndrome.

    BMC ophthalmology, 23, 1, 382, 382, 2023年09月19日, [国際誌]
    英語, 研究論文(学術雑誌), BACKGROUND: Posterior scleritis is an inflammatory reaction of the sclera that occurs posterior to the ora serrata. The aim of this study was to present a case of posterior scleritis and to analyze choroidal circulatory and structural changes using laser speckle flowgraphy (LSFG) and optical coherence tomography (OCT), respectively. CASE PRESENTATION: A 64-year-old man presented to our department because of hyperemia of the left eye for one week, diplopia, ocular pain, and distorted vision when looking leftward. At an initial examination, his best-corrected visual acuity was 1.0 Oculi uterque (OU), with mild conjunctival hyperemia oculus dexter (OD) and marked ciliary hyperemia oculus sinister (OS). Color fundus photographs revealed a cluster of choroidal folds extending from the macula to the inferior retinal region OS. Swept-Source OCT showed choroidal thickening OD, and bacillary layer detachment and paracentral middle maculopathy on the paracentral side of the optic nerve papilla, suggesting severe inflammation. Fluorescein angiography showed hyperfluorescence in the optic disc and window defects around the macula OU. Indocyanine green angiography showed mottled choroidal vascular hyperpermeability findings in the late stage. B-mode echography displayed thickening of the posterior wall of the left eye. Orbital magnetic resonance imaging showed the thickened posterior eyeball. The patient was diagnosed with posterior scleritis, and 30 mg of oral prednisolone was then given and tapered off over the next 4 months. The hyperemia and intraocular inflammation resolved after the treatment. The rate of change in macular blood flow assessed by the mean blur rate on LSFG was 20.5% and 20.2% decrease OD and OS, respectively, before and after treatment. The central choroidal thickness showed 8.8% and 37.8% decrease OD and OS, respectively. CONCLUSION: Posterior scleritis complicated with choroiditis was suggested to show different choroidal circulatory dynamics from those in other choroidal inflammations.
  • Phosphorylation of αB-Crystallin Involves Interleukin-1β-Mediated Intracellular Retention in Retinal Müller Cells: A New Mechanism Underlying Fibrovascular Membrane Formation.

    英語, 研究論文(学術雑誌), PURPOSE: Chronic inflammation plays a pivotal role in the pathology of proliferative diabetic retinopathy (PDR), in which biological alterations of retinal glial cells are one of the key elements. The phosphorylation of αB-crystallin/CRYAB modulates its molecular dynamics and chaperone activity, and attenuates αB-crystallin secretion via exosomes. In this study, we investigated the effect of phosphorylated αB-crystallin in retinal Müller cells on diabetic mimicking conditions, including interleukin (IL)-1β stimuli. METHODS: Human retinal Müller cells (MIO-M1) were used to examine gene and protein expressions with real-time quantitative PCR, enzyme linked immunosorbent assay (ELISA), and immunoblot analyses. Cell apoptosis was assessed by Caspase-3/7 assay and TdT-mediated dUTP nick-end labeling staining. Retinal tissues isolated from the Spontaneously Diabetic Torii (SDT) fatty rat, a type 2 diabetic animal model with obesity, and fibrovascular membranes from patients with PDR were examined by double-staining immunofluorescence. RESULTS: CRYAB mRNA was downregulated in MIO-M1 cells with the addition of 10 ng/mL IL-1β; however, intracellular αB-crystallin protein levels were maintained. The αB-crystallin serine 59 (Ser59) residue was phosphorylated with IL-1β application in MIO-M1 cells. Cell apoptosis in MIO-M1 cells was induced by CRYAB knockdown. Immunoreactivity for Ser59-phosphorylated αB-crystallin and glial fibrillary acidic protein was colocalized in glial cells of SDT fatty rats and fibrovascular membranes. CONCLUSIONS: The Ser59 phosphorylation of αB-crystallin was modulated by IL-1β in Müller cells under diabetic mimicking inflammatory conditions, suggesting that αB-crystallin contributes to the pathogenesis of PDR through an anti-apoptotic effect.

    BMC ophthalmology, 23, 1, 270, 270, 2023年06月13日, [国際誌]
    英語, 研究論文(学術雑誌), BACKGROUND: Metastatic choroidal tumors are hematogenous intraocular metastases of malignant tumors in systemic organs; however, the details of choroidal circulation and morphological changes in the choroid are unknown. The aim of this study is to present a case of metastatic choroidal tumor and examine laser speckle flowgraphy (LSFG)-based choroidal circulation and central choroidal thickness (CCT) before and after chemoradiotherapy. CASE PRESENTATION: A 66-year-old woman with a medical history of breast cancer 16 years ago was referred to our department struggling with blurred vision in her right eye. At the time of initial examination, her best-corrected visual acuity (BCVA) was 0.4 oculus dexter (OD) and 0.9 oculus sinister. Fundus revealed a yellowish-white choroidal elevated lesion measuring 8 papillary diameters with serous retinal detachment (SRD) in the posterior pole. Fluorescein angiography showed diffuse hyperfluorescence and fluorescent leakage due to SRD, and indocyanine green angiography demonstrated no abnormalities in the macula but hypofluorescence in the center of the tumor. Based on these clinical findings, she was diagnosed with metastatic choroidal tumor. After chemoradiotherapy, the metastatic choroidal tumor became scarred, and SRD disappeared. The rate of changes in macular blood flows assessed by mean blur rate on LSFG and CCT of her right eye were 33.8 and 32.8% decrease at 5 months after the initial visit, respectively. BCVA was 0.5 OD 27 months after the initial examination. CONCLUSION: Chemoradiotherapy resulted in regression of the metastatic choroidal tumor and disappearance of SRD, with a decrease in central choroidal blood flow and CCT. The choroidal blood flow on LSFG could reflect an increased oxygen demand by cancer cells invading the choroid and substantial blood supply.

    英語, 研究論文(学術雑誌), BACKGROUND: Vaccination against the worldwide pandemic coronavirus disease 2019 (COVID-19) is underway; however, some cases of new onset uveitis after vaccination have been reported. We report a case of bilateral acute posterior multifocal placoid pigment epitheliopathy-like (AMPPE-like) panuveitis after COVID-19 vaccination in which the patient's pathological condition was evaluated using multimodal imaging. CASE PRESENTATION: A 31-year-old woman experienced bilateral hyperemia and blurred vision starting 6 days after her second inoculation of the COVID-19 vaccination. At her first visit, her visual acuity was decreased bilaterally, and severe bilateral anterior chamber inflammation and bilateral scattering of cream-white placoid lesions on the fundus were detected. Optical coherence tomography (OCT) showed serous retinal detachment (SRD) and choroidal thickening in both eyes (OU). Fluorescein angiography (FA) revealed hypofluorescence in the early phase and hyperfluorescence in the late phase corresponding to the placoid legions. Indocyanine green angiography (ICGA) showed sharply marginated hypofluorescent dots of various sizes throughout the mid-venous and late phases OU. The patient was diagnosed with APMPPE and was observed without any medications. Three days later, her SRD disappeared spontaneously. However, her anterior chamber inflammation continued, and oral prednisolone (PSL) was given to her. Seven days after the patient's first visit, the hyperfluorescent lesions on FA and hypofluorescent dots on ICGA partially improved; however, the patient's best corrected visual acuity (BCVA) recovered only to 0.7 OD and 0.6 OS, and the impairment of the outer retinal layer was broadly detected as hyperautofluorescent lesions on fundus autofluorescence (FAF) examination and as irregularity in or disappearance of the ellipsoid and interdigitation zones on OCT, which were quite atypical for the findings of APMPPE. Steroid pulse therapy was performed. Five days later, the hyperfluorescence on FAF had disappeared, and the outer retinal layer improved on OCT. Moreover, the patient's BCVA recovered to 1.0 OU. Twelve months after the end of treatment, the patient did not show any recurrences. CONCLUSIONS: We observed a case of APMPPE-like panuveitis after COVID-19 vaccination featuring some atypical findings for APMPPE. COVID-19 vaccination may induce not only known uveitis but also atypical uveitis, and appropriate treatment is required for each case.

    英語, 研究論文(学術雑誌), PURPOSE: Patients with dry eye disease (DED) sometimes complain of ocular pain. DED-related ocular pain has many similarities with neuropathic pain. Mirogabalin, a novel ligand for the α2δ subunit of voltage-gated calcium channels, is approved for treating neuropathic pain in Japan. This study aimed to investigate the effect of mirogabalin on hyperalgesia and chronic ocular pain in a rat DED model. METHODS: DED was induced in female Sprague Dawley rats by unilaterally excising the external lacrimal gland (ELG) and Harderian gland (HG). After 4 weeks of ELG and HG removal, tear production (pH threads) and corneal epithelial damage (fluorescein staining) were evaluated. Corneal hyperalgesia and chronic pain were analyzed, respectively, by measuring capsaicin-induced eye-wiping behavior and c-Fos expression in the trigeminal nucleus. Mirogabalin (10 or 3 mg/kg) was evaluated for effects on DED-induced hyperalgesia and chronic ocular pain. RESULTS: Tear production was significantly lower in DED-induced eyes than in control eyes. Corneal damage was significantly higher in DED eyes than in control eyes. Hyperalgesia and chronic ocular pain were detected 4 weeks after ELG and HG removal. Five days of mirogabalin administration significantly suppressed capsaicin-induced eye-wiping behavior, which indicated the suppression of ocular hyperalgesia. Administration of 10 mg/kg mirogabalin significantly reduced c-Fos expression in the trigeminal nucleus, which indicated the amelioration of chronic ocular pain. CONCLUSIONS: Mirogabalin suppressed DED-induced hyperalgesia and chronic ocular pain in a rat DED model. Our findings suggested that mirogabalin might effectively alleviate chronic ocular pain in patients with DED.

    英語, 研究論文(学術雑誌), BACKGROUND: Choroidal melanocytosis is characterized by congenital diffuse melanin pigmentation with extensive parenchymal infiltration of spindle cells in the choroid; however, little is known about the choroidal circulation and morphological changes. We herein report a case of choroidal melanocytosis observed by multimodal imaging with laser speckle flowgraphy (LSFG). CASE PRESENTATION: A 56-year-old woman was referred to our hospital because of serous retinal detachment (SRD) in her left eye. At the initial examination, her best-corrected visual acuity (BCVA) was 1.5 oculus dexter (OD) and 0.8 oculus sinister (OS). An irregular, flat, brownish lesion was noted around the macula OS. Optical coherence tomography showed a choroidal structure with marked hyporeflectivity and SRD where the retinal thickness was preserved. Indocyanine green angiography demonstrated fluorescence blockade throughout. Fundus autofluorescence revealed enlarged macular hypofluorescence, suggesting chronic retinal pigment epithelium damage associated with prolonged SRD. B-mode echography showed no choroidal elevation. Based on the clinical findings, the left eye was diagnosed with choroidal melanocytosis. Four years and 10 months after the initial visit, her BCVA was 0.5 and SRD remained. During the entire period of observation, the mean blur rate (MBR) (mean ± standard deviation) of choroidal blood flow velocity on LSFG was 10.15 ± 0.72 arbitrary units (AU) OD and 1.31 ± 0.06 AU OS. CONCLUSION: Choroidal melanocytosis presented with chronic minor circulatory disturbances due to melanocyte proliferation in the choroid, but the markedly low MBR values by LSFG were dissociated from her retinal thickness and visual function. The proliferation of melanocytes may be a cause of overestimating the cold-color signal of LSFG due to their pigmentation.

    英語, 研究論文(学術雑誌), PURPOSE: To reveal the steroid-sparing effect of adalimumab (ADA) in the treatment for the chronic recurrent phase of Vogt-Koyanagi-Harada (VKH) disease. CASES AND METHODS: Thirty-six eyes from 18 cases of the recurrent phase of VKH disease treated with ADA over 12 months were examined retrospectively. Before the introduction of ADA, 4 cases received prednisolone (PSL) monotherapy and other 14 cases received PSL and cyclosporine A (CYA) combination therapy. RESULTS: In cases treated with PSL and CYA, CYA was discontinued when ADA was introduced. The minimum dose of PSL to control intraocular inflammation (min dose of PSL) could be reduced in all cases after the introduction of ADA (from 16.9 ± 7.9 mg to 6.3 ± 3.1 mg). No serious adverse events were observed in the observational periods. CONCLUSION: By comparing the min dose of PSL before and after the introduction of ADA, the steroid-sparing effect of ADA was confirmed.

    英語, 研究論文(学術雑誌), BACKGROUND/AIM: The aim of this study was to analyze choroidal circulatory and structural changes using laser speckle flowgraphy (LSFG) and optical coherence tomography (OCT) in acute macular neuroretinopathy (AMN) after infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), respectively. CASE REPORT: A 24-year-old woman complained of distorted vision after SARS-CoV-2 infection oculi uterque (OU) and referred to our hospital because of ellipsoid zones (EZ) disruption on OCT. Her best-corrected visual acuity (BCVA) was 1.2 OU. Color fundus photographs revealed dark red lesions in the macula, and scanning laser ophthalmoscopy infrared images showed hypointensity consistent with dark red lesions OU. We diagnosed the patient with AMN after SARS-CoV-2 infection, and posterior sub-Tenon injections of triamcinolone acetonide were performed OU. Five months after the initial visit, her BCVA was 1.2 OU, and EZ disruption improved. The rate of change in macular blood flow assessed by the mean blur rate on LSFG was 20.4% and 29.6% increase oculus dexter (OD) and oculus sinister (OS) 5 months after the initial visit, respectively. The central choroidal thickness showed 13.5% increase OD and 16.1% increase OS. The binarization technique demonstrated that the ratio of luminal areas in choroidal area increased by 12.6% OD and 14.2% OS, and stromal areas increased by 7.3% OD and 16.9% OS. CONCLUSION: Before and after treatment for AMN, the luminal component may have increased with improvement of acute choroidal circulatory disturbance caused by SARS-CoV-2, and increased stromal components may be due to chronic inflammation and tissue remodeling of the stroma.

    英語, 研究論文(学術雑誌), PURPOSE: The aim of this study was to compare the timing of peripapillary vascular damage between functional and structural parameters and examine their involvement with neurovascular coupling at different stages of diabetic retinopathy (DR). METHODS: One hundred ninety eyes of 143 patients with type 2 diabetes mellitus (DM) and 88 healthy control eyes were enrolled. Eyes of DM patients were divided into 3 stages with no diabetic retinopathy (NDR), non-proliferative diabetic retinopathy (NPDR), and proliferative diabetic retinopathy (PDR). NPDR and PDR eyes were treatment-naive. OCT angiography was used to calculate radial peripapillary capillary (RPC)-flux index (FI) and RPC-perfusion density (PD). Spectral domain OCT was used to measure retinal nerve fiber layer (RNFL) thickness within the corresponding RPC areas. RESULTS: RPC-FI significantly decreased in NDR eyes compared to control eyes and thereafter remained unchanged among DM (NDR, NPDR, and PDR) eyes. In contrast, RPC-PD stayed unaltered between control and NDR eyes and significantly decreased in NPDR followed by PDR eyes at similar levels. From control to NPDR eyes, RNFL thickness showed positive correlations with both RPC-FI and RPC-PD, indicative of functional and structural neurovascular coupling. These vascular parameters were also correlated with each other in control and NPDR eyes but not NDR eyes, consistent with the difference in the timing of vascular damage between functional and structural parameters. CONCLUSIONS: Circulatory dysfunction preceded structural loss while maintaining peripapillary neurovascular coupling during progression of DR stages. RPC-FI would likely be more sensitive than RPC-PD in detecting early vascular damage in DR.

    英語, 研究論文(学術雑誌), PURPOSE: To analyze the 2-year treatment outcomes of triple therapy with standard-fluence photodynamic therapy (PDT), intravitreal injection of ranibizumab (IVR)/aflibercept (IVA), and sub-tenon injection of triamcinolone acetonide (STTA) for neovascular age-related macular degeneration (nAMD) in Japanese patients. STUDY DESIGN: A retrospective, clinical case-series study. METHODS: Forty-four eyes of 44 patients with treatment-naïve nAMD followed for more than 24 months were evaluated. Initial treatment was given with triple therapy and retreatment with IVR/IVA as a pro re nata regimen. Best-corrected visual acuity (BCVA), central retinal thickness (CRT), the number of treatments, and intraocular pressure elevation were analyzed. RESULTS: The mean age was 73.3 ± 10.0 years. The mean BCVA significantly improved from 0.61 ± 0.30 at baseline to 0.50 ± 0.46 at 24 months (p = 0.034). CRT significantly improved from 373 ± 162 μm at baseline to 200 ± 107 μm at 24 months (p < 0.001). The number of treatments given during the 2-year treatment period was 2.7 ± 1.8. No retreatments were necessary in 18 of 44 eyes (40.9%), with no significant difference between IVR (46.4%) or IVA (31.3%) used during the 2-year follow-up of triple therapy (p = 0.51). Four eyes (9.1%) temporarily required glaucoma eye drop treatments. CONCLUSION: In nAMD patients, induction treatment with triple therapy resulted in approximately 40% of the patients requiring no retreatment for 2 years. The type of anti-VEGF agents used made no difference in the results.

    英語, BACKGROUND/AIM: Masquerade syndrome is characterized by uveitis-like manifestations caused by tumor cell infiltration into the ocular tissues. The aim of the study was to report a lung cancer patient with persistent unilateral vitreous opacity, who was eventually diagnosed with masquerade syndrome using cell block preparation. CASE REPORT: An 82-year-old female complained of blurred vision in her left eye (OS). Because of pulmonary adenocarcinoma, she had previously received anticancer drug treatment at another Hospital and achieved partial remission. Ophthalmic examinations revealed anterior chamber inflammation and vitreous opacity OS. Corticosteroid eye drops were administered, but the inflammation did not improve, and was referred to the Hokkaido University Hospital. The left best-corrected visual acuity was 0.1 with normal intraocular pressure. Anterior chamber inflammation was 2+ cells, and vitreous haze was 4+ OS. B-mode ultrasonography showed diffuse heterogeneous high echoic changes in the vitreous cavity. She underwent vitrectomy, and cell block preparation of the vitreous infusion fluids was performed. Cytopathology revealed adenocarcinoma cells with a high nuclear/cytoplasmic ratio and glandular formation. The immunocytochemical study showed that tumor cells were positive for thyroid transcription factor-1 (TTF-1), napsin A, and CK7, therefore diagnosis of masquerade syndrome due to intraocular metastasis of pulmonary adenocarcinoma was reached. Chemoradiotherapy was administered, and the eye got phthisis bulbi after irradiation 2 years after diagnosis. CONCLUSION: Cell block preparation using vitreous humor may be useful in the diagnosis and management of intraocular metastasis of pulmonary adenocarcinoma in patients with prolonged vitreous opacity.

    PloS one, 18, 11, e0294745, 2023年, [国際誌]
    英語, 研究論文(学術雑誌), PURPOSE: Angiopoietin (Ang) 2 is released from vascular endothelial cells by the stimulation of vascular endothelial growth factor (VEGF)A. Ang2 increases the expression of leukocyte adhesion molecules on endothelial cells via nuclear factor κB. The aim of this study was to evaluate the effects of Ang2 and VEGFA on ocular autoimmune inflammation. METHODS: We measured the concentrations of Ang2 and VEGFA in vitreous samples among patients with uveitis. Vitreous samples were collected from 16 patients with idiopathic uveitis (uveitis group) and 16 patients with non-inflammatory eye disease (control group). Experimental autoimmune uveoretinitis (EAU) was induced in B10.BR mice with a human interphotoreceptor retinoid-binding protein-derived peptide. The retinochoroidal tissues of the EAU mice were removed, and the mRNA levels of Ang2 and VEGFA were examined. EAU mice treated with anti-Ang2, anti-VEGFA, a combination of anti-Ang2 and anti-VEGFA, anti-Ang2/VEGFA bispecific, or IgG control antibodies were clinically and histopathologically evaluated. RESULTS: The protein levels of Ang2 and VEGFA were significantly higher in the vitreous samples of patients with uveitis than in controls (P<0.05). The retinochoroidal mRNA levels of Ang2 and VEGFA were significantly upregulated in EAU mice compared to controls (n = 6, P<0.05). Although there was no significant difference, treatment with anti-VEGFA antibody reduced the clinical and histopathological scores. However, treatment with anti-Ang2 antibody reduced the clinical and histopathological scores (n = 18-20, P<0.05). Furthermore, these scores were further decreased when treated by inhibiting both Ang2 and VEGFA. CONCLUSIONS: Based on these results, VEGFA and Ang2 were shown to be upregulated locally in the eye of both uveitis patients and models of uveitis. Dual inhibition of Ang2 and VEGFA is suggested to be a new therapeutic strategy for uveitis.

    American journal of ophthalmology case reports, 28, 101708, 101708, 2022年12月, [国際誌]
    英語, 研究論文(学術雑誌), PURPOSE: To describe the clinical course of a case of posterior polar annular choroidal dystrophy (PPACD) followed for 5 years. OBSERVATIONS: A 64-year-old female patient presented with blurred vision. The patient had no subjective symptoms of night blindness or visual field defects. At the initial visit, the patient's visual acuity was 20/20 in both eyes. Bilateral fundus examination revealed atrophic lesions surrounding the optic nerve head, extending to the temporal arcades in an annular pattern. Fundus autofluorescence (FAF) revealed hypoautofluorescent areas corresponding to atrophic lesions, and Goldmann perimetry revealed ring scotomas consistent with lesions in the fundus. Swept-source optical coherence tomography revealed retinal pigment epithelium atrophy, loss of the choriocapillaris, and dilation of the choroidal medium and large vessels in the atrophic area. Full-field electroretinography revealed a mild reduction in the combined rod-cone response. Laser speckle flowgraphy revealed a cold color in the posterior pole of both eyes. Based on clinical and imaging findings, the patient was diagnosed with PPACD and followed up for 5 years. At the 5-year visit, visual acuity remained unchanged, while FAF and Goldmann perimetry revealed a slight enlargement of the atrophic lesions and scotoma in both eyes, respectively. CONCLUSIONS AND IMPORTANCE: In the present case, atrophic lesions insidiously progressed and resulted in a slight enlargement of the hypoautofluorescent area and scotoma over a 5-year follow-up period, indicating that PPACD is a gradually progressive dystrophy.

    英語, PURPOSE: Acute posterior multifocal placoid pigment epitheliopathy (APMPPE) is a disease characterized by multiple yellowish-white placoid lesions. Although most lesions resolve spontaneously, some turn into scars and lead to permanent visual dysfunction. In this report, we found suggestive findings in fundus autofluorescence (FAF) that may be useful for distinguishing severe lesions requiring treatment in APMPPE. OBSERVATION: Case 1: A 29-year-old woman was referred to our hospital with multiple yellowish-white placoid lesions on the fundi of both eyes (OU). FAF showed hyperautofluorescence in some of these placoid lesions. Based on the findings of fluorescein angiography, a diagnosis of APMPPE was established, and oral prednisolone (PSL) was initiated, given that some lesions were located in the macula. One week later, exacerbation occurred with the newly developed hyperautofluorescent lesions. Some lesions in the right eye (OD) that were hyperautofluorescent at the first visit became hypoautofluorescent. Afterward, although all hypoautofluorescent lesions persisted, most of the hyperautofluorescent lesions disappeared, so oral PSL could be stopped. Two months later, however, the recurrence occurred along with multiple new placoid lesions. Some lesions located at the macula were hyperautofluorescent on FAF OU, indicating the possibility of becoming scar lesions with hypoautofluorescence. Accordingly, oral PSL was given again. CASE 2: A 47-year-old woman noticed decreased vision OD, and she was referred to us. Multiple yellowish-white placoid lesions were seen in the fundi OU. FAF showed hyperautofluorescence both with and without corresponding hypoautofluorescence in the placoid lesions OU. A diagnosis of APMPPE was established, and oral PSL was initiated. Four months later, some lesions that were hyperautofluorescent at the first visit had turned isoautofluorescent, and some lesions OU became hypoautofluorescent. However, all hypoautofluorescent lesions remained hypoautofluorescent OU. Only some hyperautofluorescent lesions recovered to isoautofluorescence without scars. CONCLUSIONS AND IMPORTANCE: In APMPPE, lesions showing hyperautofluorescence on FAF may change into hypoautofluorescence indicating scar formation. Therefore, the presence of hyperautofluorescent lesions in the macula may be a good indicator of the need for intensive corticosteroid treatments to avoid leaving hypoautofluorescent scars that are related to irreversible visual dysfunction.

    英語, 研究論文(学術雑誌), BACKGROUND: Intraocular lymphoma (IOL) is a masquerade syndrome that mimics uveitis, making diagnosis difficult. The serum soluble interleukin-2 receptor (sIL-2R), which is cleaved by matrix metalloproteinase (MMP) -2 and MMP-9, has been recognized as a tumor-related biomarker of malignant lymphomas. The aim of this study was to review the reliability of serum and vitreous sIL-2R for distinguishing IOL from uveitis. METHODS: Patients who underwent diagnostic vitrectomy for marked vitreous haze at Hokkaido University Hospital between April 2014 and June 2019 were enrolled. The patients were divided into an IOL group and a uveitis group, according to the pathology of their vitreous samples. The IOL group was further divided at the time of vitrectomy into patients who already had extraocular involvement (IOL with extraocular involvement group) and patients with no evidence of having extraocular involvement (IOL without extraocular involvement group). Serum sIL-2R, and intravitreal sIL-2R, MMP-2, and MMP-9 levels were assessed. RESULTS: Twenty-five eyes of 25 patients, and 15 eyes of 15 patients were included in the IOL group and uveitis group, respectively. The serum sIL-2R levels were significantly lower in the IOL group than in the uveitis group (P < 0.05), and 20.0% and 66.7% in the IOL and the uveitis group showed high sIL-2R value above the normal range. Vitreous sIL-2R tended to be higher in the IOL group than in the uveitis group (P = 0.80). Serum sIL-2R was significantly lower in the IOL without extraocular involvement group than in the IOL with extraocular involvement group (P < 0.05); 5.9% in the IOL without extraocular involvement group and 50.0% in the IOL with extraocular involvement group showed high sIL-2R value above the normal range. Vitreous sIL-2R, MMP-2, and MMP-9 tended to be higher in the IOL with extraocular involvement group than in the IOL without extraocular involvement group (P = 0.30, < 0.05, 0.16). CONCLUSIONS: Serum sIL-2R is often within the normal range in IOL patients. Even if it is within the normal range, the possibility of IOL should be considered. Serum sIL-2R is not a reliable biomarker for IOL, whereas vitreous sIL-2R may be useful for the diagnosis of IOL.

    英語, 研究論文(学術雑誌), PURPOSE: Retinal vessels reflect alterations related to hypertension and arteriosclerosis in the physical status. Previously, we had reported a deep-learning algorithm for automatically detecting retinal vessels and measuring the total retinal vascular area in fundus photographs (VAFP). Herein, we investigated the relationship between VAFP and brachial-ankle pulse wave velocity (baPWV), which is the gold standard for arterial stiffness assessment in clinical practice. METHODS: Retinal photographs (n = 696) obtained from 372 individuals who visited the Keijinkai Maruyama Clinic for regular health checkups were used to analyze VAFP. Additionally, the baPWV was measured for each patient. Automatic retinal-vessel segmentation was performed using our deep-learning algorithm, and the total arteriolar area (AA) and total venular area (VA) were measured. Correlations between baPWV and several parameters, including AA and VA, were assessed. RESULTS: The baPWV was negatively correlated with AA (R = -0.40, n = 696, P < 2.2e-16) and VA (R = -0.36, n = 696, P < 2.2e-16). Independent variables (AA, sex, age, and systolic blood pressure) selected using the stepwise method showed a significant correlation with baPWV. The estimated baPWV, calculated using a regression equation with variables including AA, showed a better correlation with the measured baPWV (R = 0.70, n = 696, P < 2.2e-16) than the estimated value without AA (R = 0.68, n = 696, P < 2.2e-16). CONCLUSIONS: AA and VA were significantly correlated with baPWV. Moreover, baPWV estimated using AA correlated well with the actual baPWV. VAFP may serve as an alternative biomarker for evaluating systemic arterial stiffness.

    European journal of ophthalmology, 32, 6, 3712, 3719, 2022年11月, [国際誌]
    英語, 研究論文(学術雑誌), BACKGROUND: Cyclodialysis cleft is an uncommon finding due to blunt ocular trauma. A larger and more chronic cyclodialysis requires surgical repair. The aim of this study was to introduce a minimally invasive suturing technique for the lens-sparing repair of traumatic cyclodialysis cleft and evaluate outcomes. METHODS: This study was a retrospective case series. The medical and surgical records of five patients with traumatic cyclodialysis cleft who underwent this surgery were reviewed. The surgeon (Y.S.) dissected a fornix-based conjunctival flap and created a 90° circumferential and limbal-based scleral flap. Several small incisions parallel to the limbus were made within the scleral bed 1.5 and 3 mm posterior to the limbus. After suprachoroidal fluid drainage, tiny bumps in the ciliary body were exposed from the incisions and sewn directly onto the scleral bed with 10-0 nylon sutures. RESULTS: The mean age of the patients was 37.8 ± 1.3 years. The mean duration from injury to surgery was 14.8 ± 16.7 months. Mean best-corrected visual acuity (BCVA) was 0.56 ± 0.70 and intraocular pressure (IOP) was 5.2 ± 1.9 mmHg. In all patients, IOP normalized and BCVA then returned to baseline following this procedure. Mean postoperative BCVA was 1.17 ± 0.86 and IOP was 17.8 ± 1.3 mmHg. Mean IOP and BCVA recovery times were 82.0 ± 139.6 and 294.3 ± 284.3 days, respectively. CONCLUSIONS: Partial ciliary body direct suturing under the scleral flap is a less invasive surgical option without lensectomy and considered safe and effective as a primary surgical repair for traumatic cyclodialysis cleft.

    Journal of glaucoma, 2022年10月12日, [国際誌]
    英語, 研究論文(学術雑誌), PRCIS: Decreasing aqueous outflow resistance at trabecular meshwork is the main mechanism of modified 360-degree suture trabeculotomy, and the preoperative C-value, which shows aqueous outflow resistance, is likely to be useful for predicting IOP reduction. PURPOSE: To clarify the mechanism of intraocular pressure (IOP) reduction and the preoperative prognostic predictor of modified 360-degree suture trabeculotomy (ST). PATIENTS AND METHODS: Forty-three eyes of 32 patients with glaucoma who underwent ST at Hokkaido University Hospital between April 2017 and February 2020 were enrolled. The records of postoperative IOP and coefficient of aqueous outflow (C-value) after ST were reviewed from clinical charts retrospectively. Preoperative IOP and C-values were also reviewed and considered as the baseline. RESULTS: Although the differences were not significant, IOP decreased to 15.4±3.3 mmHg at 3 months (P=0.10) and 16.1±3.8 mmHg at 6 months (P=0.21). In addition, there were significant decreases in anti-glaucoma medication scores at both 3 and 6 months after surgery (P<0.01). The C-value increased significantly to 0.24±0.11 µl/min/mmHg at 3 months (P<0.01) and increased significantly to 0.27±0.14 µl/min/mmHg at 6 months (P<0.01). The rates of change in IOP were negatively correlated with that in the C-value at 3 months (r=-0.49 and P<0.01) and 6 months (r=-0.46 and P<0.01). The success rate (IOP<21 mmHg, IOP reduction>20%) was greater in the low baseline C-value group (≤0.17) than high baseline C-value group (>0.17) (P<0.05), and the baseline IOP and C-values were statistically significant in association with the success (P<0.05) at 6 months. CONCLUSIONS: Increased conventional outflow by elimination of the aqueous outflow resistance at the trabecular meshwork is the main mechanism of IOP reduction after ST. Preoperative examination of tonographic outflow facility may be useful for predicting the IOP reduction and outcome of ST.

    英語, 研究論文(学術雑誌), PURPOSE: The aim of this study was to evaluate the clinicopathological features and flow cytometry (FCM) of tumor tissues in ocular adnexal diffuse large B-cell lymphoma (DLBCL). METHODS: This retrospective, multicenter case study was designed to evaluate the clinical and immunohistochemical features of tumors. DLBCL was diagnosed based on histopathology, immunoglobulin (Ig) heavy chain gene rearrangement, and FCM in all surgically removed periocular tumor tissues. This study involved assessing percentages (%) of B-cell/T-cell markers, a natural killer cell marker, and cell-surface Ig kappa/lambda (κ/λ) expression measured by FCM analysis in tumor tissues. RESULTS: Eleven DLBCL patients (4 men and 7 women) with 11 tumors were enrolled in this study. The median age at the time of initial presentation was 73 years. The tumor cells were immunohistochemically positive for cluster of differentiation (CD) 20, while CD5 was negative in all 8 cases tested. At the time of ophthalmic diagnosis, two cases already showed systemic dissemination of DLBCL throughout the body. FCM of tumor tissues detected a high percentage of B-cell markers including CD19 and CD20 in all 11 tumors. One case with high CD10 levels in FCM was histologic transformation from follicular lymphoma. One case with a relatively low CD20 population involved a history of systemic treatments including intravenous rituximab. CONCLUSION: Although caution should be exercised when interpreting the data, FCM is useful for not only supportive diagnosis complementary to immunohistochemistry, but also facilitates a better understanding of immunopathology including histologic transformation of follicular lymphoma to DLBCL in the ocular adnexa.

    American journal of ophthalmology case reports, 27, 101568, 101568, 2022年09月, [国際誌]
    英語, 研究論文(学術雑誌), PURPOSE: To report a case of polycythemia vera (PV) with subretinal fluid accumulation after the administration of prostaglandin I2 (PGI2) analogue. OBSERVATIONS: A 57-year-old woman diagnosed as having PV was referred to our department for the evaluation of severe metamorphopsia in the left eye, which gradually progressed after the initiation of oral administration of PGI2 mimetics. At the first visit, the patient's best-corrected visual acuities (BCVAs) were 20/20 OD and 20/30 OS. Fundus examination and optical coherence tomography revealed the presence of subretinal fluid (SRF) in the left eye and multiple serous pigment epithelial detachments (PEDs) in both eyes. Fluorescein angiography revealed central serous chorioretinopathy (CSC)-like lesions, consisting of dye pooling corresponding to the PEDs in both eyes and dye leakage in the left eye. Indocyanine green angiography and laser speckle flowgraphy revealed dilated choroidal veins and reduced choroidal blood flow, respectively. The central choroidal thickness (CCT) measured at the first visit showed a relatively thickened choroid in the left eye. Laboratory data showed mild pancytosis. The patient was diagnosed as having CSC associated with a background of PV, presumably triggered by the PGI2 analogue. One month after cessation of drug administration, the patient's BCVA improved, the CCT slightly decreased, and serous retinal detachment and PED disappeared in the left eye. CONCLUSIONS AND IMPORTANCE: Our case of PV presenting with CSC-like lesions after PGI2 analogue administration indicates the possible risk of SRF accumulation by PGI2 analogues in patients with PV.

    英語, 研究論文(学術雑誌), PURPOSE: To clarify the proportion of ocular sarcoidosis with severe, refractory, and prolonged inflammation and their association with ocular complications and visual prognosis. STUDY DESIGN: Multicenter, retrospective, longitudinal cohort study. METHODS: Three hundred and twenty-three eyes of 164 patients (45 men; 119 women) with ocular sarcoidosis who visited Hokkaido University Hospital and Yokohama City University Hospital from 2010 to 2015. We newly defined severe, refractory, and prolonged inflammation in ocular sarcoidosis, and investigated their proportions, ocular complications and final visual acuity from medical records of our sarcoidosis patients. RESULTS: The eyes with severe inflammation numbered 72/323 (22.3%), with refractory inflammation, 80/323 (24.8%), and with prolonged inflammation, 91/323 (28.2%). The number of eyes having neither severe, refractory, nor prolonged inflammation (defined as none) was 114/323 (35.3%). The numbers of eyes that reached irreversible visual dysfunction were 6/72 (8.3%) of those with severe inflammation, 10/80 (12.5%) with refractory inflammation, 12/91 (13.2%) with prolonged inflammation, and 4/114 (6.2%) with none. As complications, cataract (62.2%), glaucoma (28.5%), epiretinal membrane (24.1%), cystoid macular edema (22.6%), vitreous hemorrhage (2.8%), choroidal atrophy (2.5%), macular degeneration (1.2%), macular hole (0.9%) and retinal detachment (0.3%) were identified. Among them, secondary glaucoma (16 eyes) and macular degeneration (4 eyes) were major complications related to irreversible visual dysfunction. CONCLUSIONS: Although most of the patients with ocular sarcoidosis had a relatively good visual prognosis, some developed severe, refractory, and/or prolonged inflammation related to the development of ocular complications, that resulted in poor visual prognosis.

    The Journal of biological chemistry, 298, 9, 102378, 102378, 2022年09月, [国際誌]
    英語, 研究論文(学術雑誌), Placental growth factor (PlGF) belongs to the vascular endothelial growth factor (VEGF) family of proteins that participate in angiogenesis and vasculogenesis. Anti-VEGF therapy has become the standard treatment for ocular angiogenic disorders in ophthalmological practice. However, there is emerging evidence that anti-VEGF treatment may increase the risk of atrophy of the retinal pigment epithelium (RPE), which is important for the homeostasis of retinal tissue. Whereas the cytoprotective role of VEGF family molecules, particularly that of VEGF A (VEGFA) through its receptor VEGF receptor-2 (VEGFR-2), has been recognized, the physiological role of PlGF in the retina is still unknown. In this study, we explored the role of PlGF in the RPE using PlGF-knockdown RPE cells generated by retrovirus-based PlGF-shRNA transduction. We show that VEGFA reduced apoptosis induced by serum starvation in RPE cells, whereas the antiapoptotic effect of VEGFA was abrogated by VEGFR-2 knockdown. Furthermore, PlGF knockdown increased serum starvation-induced cell apoptosis and unexpectedly reduced the protein level of VEGFR-2 in the RPE. The antiapoptotic effect of VEGFA was also diminished in PlGF-knockdown RPE cells. In addition, we found that glycogen synthase kinase 3 activity was involved in proteasomal degradation of VEGFR-2 in RPE cells and inactivated by PlGF via AKT phosphorylation. Overall, the present data demonstrate that PlGF is crucial for RPE cell viability and that PlGF supports VEGFA/VEGFR-2 signaling by stabilizing the VEGFR-2 protein levels through glycogen synthase kinase 3 inactivation.

    Journal of glaucoma, 31, 8, 682, 688, 2022年08月01日, [国際誌]
    英語, 研究論文(学術雑誌), PRCIS: A Kaplan-Meier survival curve analysis showed no significant differences in success rates between uveitic glaucoma (UG) and primary open angle glaucoma (POAG) 120 months after modified 360-degree suture trabeculotomy, which was effective for both groups in the long term. PURPOSE: The aim of this study was to examine the outcomes of modified 360-degree suture trabeculotomy in patients with UG as compared with those with POAG. PATIENTS AND METHODS: This was a retrospective, nonrandomized, and comparative case series study. Modified 360-degree trabeculotomy using a 5-0 nylon suture (S-LOT) was performed on 51 eyes of 51 patients (54.4±13.4 y) with UG between October 2005 and January 2012 at Hokkaido University Hospital. Age-matched patients with POAG who underwent S-LOT during the same period were enrolled as controls. Written informed consent was obtained from all patients enrolled in the present study. Surgical success was defined as an intraocular pressure (IOP) <18 mm Hg with similar or lower doses of antiglaucoma medications. Kaplan-Meier survival curves of surgical failure were analyzed and compared between UG and POAG. RESULTS: The mean follow-up periods (±SD) for UG and POAG were 104.8±44.0 and 98.1±36.3 months ( P =0.23), respectively. Mean preoperative IOP in UG and POAG were 34.9±11.0 and 25.3±9.4 mm Hg ( P <0.001), respectively. After surgery, mean IOP in UG and POAG decreased to 12.0±4.1 and 13.8±3.2 mm Hg, respectively, at 60 months, and 12.1±5.6 and 12.4±1.8 mm Hg ( P =0.86), respectively, at 120 months. The Kaplan-Meier survival curve analysis showed no significant differences in success rates between UG and POAG at the end of the follow-up (Log-rank test, P =0.13). Success rates in UG and POAG were 70.0 and 62.5% at 60 months, and 67.5 and 41.2% at 120 months, respectively. CONCLUSION: These results suggest that S-LOT is effective for UG and POAG alike.

    American journal of ophthalmology case reports, 26, 101478, 101478, 2022年06月, [国際誌]
    英語, 研究論文(学術雑誌), PURPOSE: Cerebrospinal fluid hypovolemia syndrome (CHS) is a rare clinical entity that can be caused by spontaneous cerebrospinal fluid (CSF) leakage. The aim of this study is to report a rare case of CHS after a traffic accident in a patient who presented with diplopia and ptosis with fluctuation and was initially diagnosed with ocular myasthenia gravis. OBSERVEATIONS: A 29-year-old man exhibited fluctuating left ptosis and diplopia after a traffic accident. Although he was suspected of having myasthenia gravis and was treated using oral pyridostigmine bromide, his symptoms did not improve. He also had orthostatic headaches and malaise after the accident. His symptoms were suspected to be associated with traumatic cerebrospinal fluid hypovolemia. After 1000-mL fluid replacement, his diplopia and ptosis improved, and orbital T2-weghted MRI detected a high-signal zone around the optic nerve. We diagnosed him with oculomotor nerve paresis associated with cerebrospinal fluid hypovolemia. The symptoms, including ptosis, diplopia, orthostatic headaches, and malaise, disappeared after epidural blood patch therapy. CONCLUSIONS AND IMPORTANCE: When treating patients with fluctuating ocular symptoms, such as diplopia and ptosis, who have a history of trauma and orthostatic headaches, the possibility of CHS should be considered in the differential diagnosis.

    BMC ophthalmology, 22, 1, 160, 160, 2022年04月07日, [国際誌]
    英語, 研究論文(学術雑誌), BACKGROUND: Chronic myeloid leukemia (CML) is known to cause leukemic retinopathy due to leukemia cell invasion into the choroid; however, details of the circulatory dynamics and morphological changes in the choroid are unknown. The aim of this study was to present a case of leukemic retinopathy and examine choroidal circulatory and structural analyses using laser speckle flowgraphy (LSFG) and optical coherence tomography with a binarization method, respectively. CASE PRESENTATION: A 15-year-old male diagnosed with CML complained of blurred vision in his right eye. He was ophthalmologically diagnosed with leukemic retinopathy due to retinal hemorrhage in both eyes. Tyrosine kinase inhibitors achieved complete cytogenetic remission and resolution of retinal hemorrhages at 6 months after treatment. After the treatment, the best-corrected visual acuity had recovered from 0.1 to 1.2 oculus dexter (OD) and remained at 1.5 oculus sinister (OS). The rate of change in macular blood flow assessed by the mean blur rate on LSFG was 18.3% increase OD and 25.2% decrease OS 19 months after treatment. The central choroidal thickness showed 0.4 and 3.1% reductions OD and OS, respectively. The binarization technique demonstrated that the rate of luminal areas in choroidal areas exhibited 3.2% increase OD but 4.8% decrease OS. CONCLUSION: Choroidal blood flow improved OD after treatment for CML, while it deteriorated OS, together with choroidal thinning due to reduction of luminal areas. The degrees of leukemia cell invasion into the choroidal tissue and tissue destruction might be different between the eyes in this case.

  • Serum advanced glycation end-products and αB-crystallin in diabetic retinopathy patients.
    Taku Yamamoto, Satoru Kase, Miyuki Murata, Susumu Ishida
    Biomedical reports, 16, 4, 28, 28, 2022年04月, [国際誌]
    英語, 研究論文(学術雑誌), αB-crystallin, one of the small heat shock proteins, which is also known as HSPB5, has cytoprotective effects under inflammatory conditions. Advanced glycation end-products (AGE) are produced through non-enzymatic glycation under conditions of hyperglycemia and they contribute to angiogenesis and inflammation. The aim of this study was to examine the levels of serum αB-crystallin and AGE concentrations in blood samples collected from proliferative diabetic retinopathy (PDR) patients. Blood samples were collected from seven diabetic patients with PDR and eight patients without diabetes mellitus who underwent vitrectomy due to PDR and idiopathic macular diseases, respectively, in a single center. The levels of serum αB-crystallin and AGE were measured by ELISA and correlations were assessed statistically. The serum levels (mean ± SEM) of AGE were significantly higher in PDR patients (28.41±0.46 µg/ml) than in patients with non-diabetic macular diseases (25.76±0.60 µg/ml; P=0.015), whereas there was no significant difference in serum αB-crystallin levels. There was one patient with an extremely high level of αB-crystallin, who was treated with systemic corticosteroid due to chronic autoimmune inflammatory diseases. The current prospective study showed that serum AGE levels were significantly higher in PDR patients; however, no correlations between serum AGE and αB-crystallin levels were identified.

    Journal of clinical medicine, 11, 5, 2022年03月03日, [国際誌]
    英語, 研究論文(学術雑誌), Purpose: The purpose of this study was to examine the diagnostic accuracy of the cell block (CB) method and clinical features affecting it in patients with vitreoretinal lymphoma (VRL). Methods: This study enrolled 38 eyes in 33 VRL patients, and 7 eyes in 7 patients with idiopathic uveitis who underwent diagnostic vitrectomy. Medical records including the results of CB cytology, interleukin (IL)-10/-6 concentrations, and immunoglobulin heavy chain gene (IgH) rearrangement were retrospectively searched. Results: Patients with VRL comprised 16 women and 17 men, and the age of onset ranged from 44 to 85 years (mean: 70 years). CB preparations detected large malignant cells in 35 eyes (92%), whereas the other 3 VRL eyes were negative. Two of the latter three eyes showed subretinal infiltrates, which existed in 7 of 35 CB-positive eyes. Intravitreal IL-10 and -6 concentrations were 1866 ± 4088 pg/mL and 98 ± 139 pg/mL, respectively, and the rate of IL-10/-6 >1 was 86.9%. The presence of IgH monoclonality was 63.2%. In patients with uveitis, CB specimens revealed no atypical but small inflammatory cells. IL-6 concentration was 311.1 ± 240 pg/mL, whereas IL-10 was undetectable in six eyes, and the IL-negative rate was 85.7%. Six eyes (85.7%) with uveitis showed no IgH monoclonality. Conclusions: Diagnostic accuracy of CB preparations in VRL could achieve an equivalent outcome to IL ratio calculation and IgH monoclonality detection. The appearance of subretinal infiltrates may diminish the CB positivity.

    英語, PURPOSE: Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a necrotizing vasculitis syndrome characterized by the destruction of small vessels, leading to various organ disorders. Here, we report a case of posterior scleritis with AAV successfully treated with prednisolone and rituximab (RTX) combination therapy. OBSERVATIONS: A 69-year-old female suffered from ocular pain and redness in her left eye for 2.5 years. She had been diagnosed with idiopathic otitis media before a year. At her initial visit, scleral injection with nodular elevated scleral lesions, vitreous haze, and serous retinal detachment (SRD) in the inferior periphery were observed in the left eye. Enhanced computed tomography revealed the enhancement and thickening of the left sclera. The results of laboratory analysis were positive for myeloperoxidase ANCA. Accordingly, she was diagnosed with AAV. Owing to the exacerbation of vitreous haze and SRD, topical treatment and steroid pulse therapy were initiated. Following therapy, anterior and posterior scleritis improved, and additional RTX was administered to maintain the remission. Following treatment, the patient has maintained remission with 10 mg/day prednisolone to date. CONCLUSIONS AND IMPORTANCE: We encountered a case of posterior scleritis with AAV in which inflammatory manifestations subsided with RTX and glucocorticoid combination therapy. RTX administration likely contributed to the maintenance of remission.

    英語, PURPOSE: Epstein-Barr virus (EBV) is a herpes virus known to cause infectious mononucleosis and several other human disorders. Ocular EBV infections that have been reported include uveitis, retinal vasculitis, and acute retinal necrosis (ARN). ARN is usually caused by herpes simplex virus (HSV) or varicella-zoster virus (VZV). ARN that is caused by EBV (EBV-ARN) is rarely seen, and only a few cases have been reported. The visual prognosis for EBV-ARN is poor, and no treatment strategy has been established. We report on a patient who was treated successfully for EBV-ARN. OBSERVATION: An 80-year-old female who had been treated with prednisolone at 5 mg/day and methotrexate at 2 mg/week for rheumatoid arthritis visited our hospital because of blurred vision in her left eye. Her left visual acuity was 20/50, and extensive white-yellowish retinal lesions at the temporal periphery with retinal hemorrhages were seen through vitreous haze. The DNA sequence of EBV, but not of HSV, VZV, or cytomegalovirus, was detected by a polymerase chain reaction (PCR) assay in the aqueous humor (4.2 × 106 copies/ml), with EBV also being positive in serum (3.5 × 102 copies/ml). The patient received 2 mg of intravitreal ganciclovir injections twice with a 3-day interval and intravenous infusion of acyclovir at 750 mg/day for 7 days; however, the retinal white lesions expanded rapidly, then dose of prednisolone was increased (40 mg/day) and vitrectomy was performed 10 days after the initial visit. After the surgery, the retinal lesion continued to enlarge. Vitreous samples showed high copies of EBV (1.2 × 108 copies/ml). Following treatment with intravenous foscarnet (4800 mg/day), which replaced the acyclovir application, the retinal white lesions gradually diminished, leaving retinal scars. To date, the patient has developed no retinal detachment and shows visual acuity over 6/60 in the left eye along with silicone oil. CONCLUSIONS: We experienced a case of EBV-ARN that was refractory to systemic acyclovir and topical ganciclovir but responded effectively to systemic foscarnet after vitrectomy. Although the clinical management remains challenging in this disease, foscarnet is considered to be one of the candidate drugs for EBV infections.

    Case reports in ophthalmology, 13, 2, 611, 616, 2022年, [国際誌]
    英語, 研究論文(学術雑誌), Optical coherence tomographic angiography (OCTA) has emerged as a rapid, noninvasive imaging modality to visualize the vascular networks in the retina and choroid. Here, we report the clinical findings in a case of primary vasoproliferative retinal tumor (VPRT) observed by the wide-field swept-source OCTA. A 74-year-old male patient with central vision loss and metamorphopsia in his left eye was referred to our hospital. At the first visit, the best-corrected visual acuity was 20/20 OD and 20/40 OS. Fundus examination revealed the presence of the epiretinal membrane and inferotemporal reddish retinal tumor in the left eye. Fluorescein angiography and indocyanine green angiography (ICGA) showed leaky characteristics and sharply defined structure of vessels in the retinal tumor, respectively. The patient was diagnosed with the VPRT with secondary epiretinal membrane and underwent pars plana vitrectomy with internal limiting membrane peeling, retinal photocoagulation, and triple freeze and thaw procedure using cryopexy. Whereas wide-field swept-source OCTA preoperatively depicted the flow signals as distinctive vascular structures similar to ICGA, the tumor color turned out to be ischemic white, and the flow signals detected by wide-field OCTA disappeared after the surgery, indicating that the freezing effect of transscleral cryopexy sufficiently reached the surface of the tumor. In sum, wide-field swept-source OCTA is a useful imaging modality that can be noninvasively and repetitively performed to determine the treatment effect in cases of peripheral retinal tumors such as VPRT.

    Ocular immunology and inflammation, 30, 7-8, 1798, 1802, 2022年, [国際誌]
    英語, 研究論文(学術雑誌), PURPOSE: The purpose of this study is to investigate matrix metalloproteinases (MMPs) expression in human intraocular lymphoma (IOL). METHODS: Two enucleated eyes and seven cell-block samples obtained from patients with IOL who underwent vitrectomy were used. Immunopathological examinations were performed for detection of MMP-2, MMP-9, and TIMP-4 expressions. RESULTS: In the enucleated eye with primary IOL (PIOL), MMP-2 was negative, and MMP-9 and TIMP-4 were positive in the lymphoma cells, while in the enucleated eye with secondary IOL (SIOL), all the molecules were positive. Among the cell-block samples with PIOL, the positive rate in lymphoma cells of MMP-2, MMP-9, and TIMP-4 was 75%, 100%, and 75%, respectively. In the cell-block samples with SIOL, the positive rates of MMP-2, MMP-9, and TIMP-4 were all 100%. CONCLUSIONS: MMP-2, MMP-9, and TIMP-4 were expressed in lymphoma cells using the specimens of human IOL, suggesting that MMPs may play an important role in the development of IOL.
  • Downregulation of AlphaB-crystallin in Retinal Pigment Epithelial Cells Exposed to Diabetes-related Stimuli In Vivo and In Vitro.

    In vivo (Athens, Greece), 36, 1, 132, 139, 2022年, [国際誌]
    英語, 研究論文(学術雑誌), BACKGROUND/AIM: AlphaB-crystallin plays a pivotal role in many diseases. However, the involvement of alphaB-crystallin in retinal pigment epithelial (RPE) cells with diabetes stimuli remains unknown. The aim of this study is to examine the alterations of RPE cells and alphaB-crystallin expression in diabetic models in vivo and in vitro. MATERIALS AND METHODS: Diabetic conditions in mice were induced by streptozotocin (STZ). The thickness of the RPE/choroid complex was measured by optical coherence tomography (OCT). Periodic acid-Schiff (PAS) staining was used to investigate the choriocapillaris in histological sections of murine eyeballs and oxidative stress was evaluated using immunofluorescence with anti-4-hydroxynonenal (HNE) antibody. AlphaB-crystallin expression was examined in the RPE/choroid complex using ELISA. Real-Time PCR was performed to evaluate the alphaB-crystallin expression in cultured human RPE cells with high glucose or following advanced glycation end-products (AGE) stimulation. RESULTS: In diabetic mice, OCT-based RPE/choroidal layers were thickened 2 months after STZ stimulation, where PAS-positive dilated choriocapillaris was noted. Immunoreactivity of 4-HNE was strongly observed in the RPE layer, from which a significant number of RPE cells was lost. Meanwhile, alphaB-crystallin expression in 2-month STZ mice was significantly lower compared to controls. In accordance with these results, in vitro data showed that the alphaB-crystallin expression was also significantly lower in RPE cells with high glucose or following AGE stimulation compared to untreated cells. CONCLUSION: In both types of diabetic models the expression of alphaB-crystallin was found to be downregulated in RPE cells and was associated with increased levels of oxidative stress.

    英語, 研究論文(学術雑誌), PURPOSE: To investigate the immunotherapeutic effects of macrophage-like induced pluripotent stem (iPS) cell-derived suppressor cells (SCs) in ocular immune response and experimental autoimmune uveoretinitis (EAU). METHODS: The genes of Oct3/4, Sox2, Klf4, and c-Myc were transferred to B cells enriched from the spleen cells of C57BL/6 mice by using retrovirus vectors. Transferred B cells were cultured for 17 days to obtain colonies of iPS cells. Through additional steps, iPS-SCs were induced. An antigen-specific T cell proliferation assay was performed with CD4+ T cells collected from draining lymph nodes of the mice immunized with human interphotoreceptor retinoid-binding protein (hIRBP) peptide and co-cultured with iPS-SCs. Cytokine concentrations in the culture supernatant were examined. Mice were immunized with hIRBP peptide to induce EAU. The iPS-SCs were administered into the mice one day before the induction of EAU. RESULTS: The iPS-SCs decreased hIRBP-specific T cell proliferation depending on the number of cells. Productions of tumor necrosis factor-α and interferon-γ were significantly decreased; however, transforming growth factor-β1, nitric oxide, interleukin (IL)-13, IL-17A, and IL-17 F levels were elevated in the supernatant when the collected T cells were co-cultured with iPS-SCs. The iPS-SCs had immunosuppressant effects even without cell-to-cell contact, and their effects were non-specific to the antigen preloaded on iPS-SCs. EAU was significantly milder in the mice administered iPS-SCs prior to immunization. CONCLUSIONS: Macrophage-like iPS-SCs reduced Th1 immune response to a retinal antigen and Th1-mediated EAU in mice. These results showed the possibility of the application of iPS technology to the treatment of noninfectious ocular inflammation, endogenous uveitis, in the future.

    英語, 研究論文(学術雑誌), PURPOSE: This study aimed to investigate the clinical features of intraocular inflammation (uveitis) in Hokkaido and to assess the etiology trends in comparison with those of our previous survey. METHODS: We retrospectively reviewed the medical records of 1,616 new referral uveitis patients (1,020 females and 596 males) in Hokkaido University Hospital between 2004 and 2014. RESULTS: Sarcoidosis was the most frequent etiology (17.4%), followed by Vogt-Koyanagi-Harada disease (8.1%), Behçet's disease (4.5%), and human leukocyte antigen B27 -associated uveitis (2.5%). The etiologies in 48.7% of the patients were unclassified. Compared to the previous survey between 1994 and 2003, the rate of Behçet's disease decreased and that of sarcoidosis increased. The rates of infectious uveitis and vitreoretinal lymphoma increased. CONCLUSION: Although the order of the top four etiologies was the same in the two surveys, the rate of sarcoidosis increased and that of Behçet's disease decreased.
  • Hypoxia Induces Galectin-1 Expression Via Autoinduction of Placental Growth Factor in Retinal Pigment Epithelium Cells.

    Investigative ophthalmology & visual science, 62, 2, 22, 22, 2021年02月01日, [国際誌]
    英語, 研究論文(学術雑誌), Purpose: Galectin-1/LGALS1, a β-galactoside-binding protein, contributes to angiogenesis and fibrosis in various ocular diseases. Hypoxia-dependent and -independent pathways upregulate galectin-1/LGALS1 expression in Müller glial cells. Here, we present novel findings on the galectin-1/LGALS1 regulatory system in human retinal pigment epithelium (RPE) cells, the major cellular participant in the pathogenesis of neovascular age-related macular degeneration (nAMD). Methods: Human RPE cells were used to evaluate changes in gene and protein expression with real-time quantitative PCR and immunoblot analyses, respectively. The promoter and enhancer regions of LGALS1 were analyzed by reporter assay and chromatin immunoprecipitation. Immunofluorescence analysis of nAMD patient specimens was used to confirm the in vitro findings. Results: Hypoxia induced galectin-1/LGALS1 expression via binding of hypoxia-inducible factor 1α (HIF-1α) to hypoxia-responsive elements in the LGALS1 promoter region. Blockade of vascular endothelial growth factor receptor 1 (VEGFR1) partially decreased hypoxia-induced galectin-1/LGALS1 expression. Among several VEGFR1 ligands induced by hypoxia, placental growth factor (PlGF)/PGF alone upregulated galectin-1/LGALS1 expression via phosphorylation of activator protein 1 (AP-1) subunits following AKT and p38 mitogen-activated protein kinase (MAPK) activation. An AP-1 site in the LGALS1 enhancer region was required for PlGF-induced galectin-1/LGALS1 expression in RPE cells. PlGF application upregulated PGF expression via extracellular signal-regulated kinase 1 and 2, AKT, and p38 MAPK pathways. nAMD patient specimens demonstrated co-localization of galectin-1 with HIF-1α, PlGF, and VEGFR1 in RPE cells. Conclusions: Our present findings implicate the significance of hypoxia as a key inducer of galectin-1/LGALS1 in RPE cells and the autoinduction of hypoxia-induced PlGF as a vicious cycle amplifying the pathogenesis of nAMD.

    英語, 研究論文(学術雑誌), BACKGROUND/AIM: This study aimed to demonstrate the clinical outcomes of primary vitreoretinal lymphoma (PVRL). PATIENTS AND METHODS: Seventeen patients with PVRL who had been treated at Hokkaido University Hospital were enrolled in this study. They were diagnosed based on their cytology, interleukin-10/-6 ratio, and immunoglobulin heavy chain (IgH) gene rearrangement. RESULTS: Diagnostic tests detected cytological malignancy among 14 cases (82.3%), high interleukin-10/-6 ratios among 16 cases (94.1%), and IgH monoclonality in 13 cases (76.5%). Systemic corticosteroids were given to seven (41.2%) patients before their diagnosis of PVRL. Treatments after diagnosis comprised intravitreal methotrexate injection, local radiation, and intravenous chemotherapy for 11, seven, and five cases, respectively. Central nervous system and systemic involvements were observed in nine and one case, respectively, and these complications occurred at 3 to 43 months (mean=16 months) after initial ocular presentation. CONCLUSION: Many of our patients did not receive any systemic intervention, and almost half of patients with PVRL developed central nervous system involvement during their follow-up period.

  • ROCK1 Mediates Retinal Glial Cell Migration Promoted by Acrolein.
    Kanae Fukutsu, Miyuki Murata, Kasumi Kikuchi, Shiho Yoshida, Kousuke Noda, Susumu Ishida
    Frontiers in medicine, 8, 717602, 717602, 2021年, [国際誌]
    英語, 研究論文(学術雑誌), Objective: Acrolein is a highly reactive aldehyde that covalently binds to cellular macromolecules and subsequently modulates cellular function. Our previous study demonstrated that acrolein induces glial cell migration, a pathological hallmark of diabetic retinopathy; however, the detailed cellular mechanism remains unclear. The purpose of this study was to investigate the role of acrolein in retinal glial cell migration by focusing on rho-associated coiled-coil-containing protein kinases (ROCKs). Methods: Immunofluorescence staining for ROCK isoforms was performed using sections of fibrovascular tissue obtained from the eyes of patients with proliferative diabetic retinopathy (PDR). Rat retinal Müller glial cell line, TR-MUL5, was stimulated with acrolein and the levels of ROCK1 were evaluated using real-time PCR and western blotting. Phosphorylation of the myosin-binding subunit of myosin light chain phosphatase [myosin phosphatase target subunit 1, (MYPT1)] and myosin light chain 2 (MLC2) was assessed. The cell migration rate of TR-MUL5 cells exposed to acrolein and/or ripasudil, a non-selective ROCK inhibitor, was measured using the Oris cell migration assay. Results: ROCK isoforms, ROCK1 and ROCK2, were positively stained in the cytosol of glial cells in fibrovascular tissues. In TR-MUL5 cells, the mRNA expression level of Rock1, but not Rock2, was increased following acrolein stimulation. In line with the PCR data, western blotting showed increase in ROCK1 and cleaved ROCK1 protein in TR-MUL5 cells stimulated with acrolein. N-acetylcysteine (NAC) suppressed acrolein-associated Rock1 upregulation in TR-MUL5 cells. Acrolein augmented the phosphorylation of MYPT1 and MLC2 and increased the cell migration rate of TR-MUL5 cells, both of which were abrogated by ripasudil. Conclusions: Our study demonstrated that ROCK1 mediates the migration of retinal glial cells promoted by the unsaturated aldehyde acrolein.

    英語, 研究論文(学術雑誌), PURPOSE: To evaluate the long-term outcomes of trabeculectomy with mitomycin C (MMC-TLE) in patients with uveitic glaucoma (UG). Patients and Methods. This was a retrospective, nonrandomized case series study. MMC-TLE was performed on 50 eyes with UG between February 2001 and January 2015 at Hokkaido University Hospital. Age- and sex-matched patients with primary open angle glaucoma (POAG) who underwent MMC-TLE were matched by age and sex and enrolled as controls. Surgical success was defined as an intraocular pressure (IOP) less than 18 or 15 mmHg. The Kaplan-Meier survival curves for surgical failure were analyzed. RESULTS: The mean preoperative IOP in UG and POAG was 27.6 ± 10.6 and 18.0 ± 4.5 mmHg, respectively. After the surgery, the mean IOP in UG and POAG was reduced to 11.7 ± 4.2 and 12.2 ± 3.8 mmHg at 12 months, 11.9 ± 7.0 and 12.1 ± 3.1 mmHg at 36 months, and 13.0 ± 5.2 and 10.6 ± 1.2 mmHg at 120 months, respectively. The success rates (IOP <18 mmHg, IOP reduction >20%) in UG and POAG were 91.7% and 88.0% at 12 months, 82.2% and 75.6% at 36 months, and 66.5% and 61.8% at 120 months, respectively. The success rates (IOP <15 mmHg) in UG and POAG were 64.0% and 58.0% at 12 months, 55.1% and 45.5% at 36 months, and 47.9% and 37.8% at 120 months, respectively. There was no significant difference in the success rate between UG and POAG at 120 months after surgery by either definition of surgical success. CONCLUSIONS: MMC-TLE effectively reduced IOP in both UG and POAG. There was no significant difference in the success rate between UG and POAG. Following sufficient inflammation suppression, surgical outcomes of UG may be comparable with those of POAG.

    Investigative ophthalmology & visual science, 61, 14, 29, 29, 2020年12月01日, [国際誌]
    英語, 研究論文(学術雑誌), Purpose: Müller glial-mesenchymal transition (GMT) is reported as the fibrogenic mechanism promoted by TGF-β-SNAIL axis in Müller cells transdifferentiated into myofibroblasts. Here we show the multifaceted involvement of TGF-β in diabetic fibrovascular proliferation via Müller GMT and VEGF-A production. Methods: Surgically excised fibrovascular tissues from the eyes of patients with proliferative diabetic retinopathy were processed for immunofluorescence analyses of TGF-β downstream molecules. Human Müller glial cells were used to evaluate changes in gene and protein expression with real-time quantitative PCR and ELISA, respectively. Immunoblot analyses were performed to detect TGF-β signal activation. Results: Müller glial cells in patient fibrovascular tissues were immunopositive for GMT-related molecular markers, including SNAIL and smooth muscle protein 22, together with colocalization of VEGF-A and TGF-β receptors. In vitro administration of TGF-β1/2 upregulated TGFB1 and TGFB2, both of which were suppressed by inhibitors for nuclear factor-κB, glycogen synthase kinase-3, and p38 mitogen-activated protein kinase. Of the various profibrotic cytokines, TGF-β1/2 application exclusively induced Müller glial VEGFA mRNA expression, which was decreased by pretreatment with small interfering RNA for SMAD2 and inhibitors for p38 mitogen-activated protein kinase and phosphatidylinositol 3-kinase. Supporting these findings, TGF-β1/2 stimulation to Müller cells increased the phosphorylation of these intracellular signaling molecules, all of which were also activated in Müller glial cells in patient fibrovascular tissues. Conclusions: This study underscored the significance of Müller glial autoinduction of TGF-β as a pathogenic cue to facilitate diabetic fibrovascular proliferation via TGF-β-driven GMT and VEGF-A-driven angiogenesis.

    英語, 研究論文(学術雑誌), PURPOSE: To establish with negative electroretinogram (ERG) the clinical entity of eight patients with unilateral severe photophobia, essentially normal fundus, good visual acuity, and severe cone and rod dysfunction. STUDY DESIGN: Multicenter retrospective observation case series. METHODS: Comprehensive ophthalmologic examinations were performed, including best-corrected visual acuity (BCVA), full-field ERGs and multifocal ERGs (mfERGs), fundus photographs, and OCT. Systemic and genetic examinations were performed. RESULTS: The mean (± SD) age at the onset was 60.0 ± 8.4 years, and the six patients noticed severe photophobia in the affected eye in spite of almost normal fundus appearance and good BCVA. The dark-adapted bright flash ERGs in the affected eye had relatively well-preserved a-waves and depressed b-waves, i.e., a negative ERG. Cone ERGs and both b- and d-waves of the photopic long-duration ERGs were almost undetectable. Rod ERGs were severely reduced; however, only two patients complained of night blindness. In five patients, the mfERGs were extinguished in the periphery but preserved in the central retina, resulting in good BCVA. Electrophysiological findings indicated a severe diffuse dysfunction of the inner retina affecting bipolar cells of both ON- and OFF-pathways, and in five patients there was a reduction in the thickness of the inner nuclear layer. In seven patients the retinal arteries were attenuated. Anti-retinal antibodies were detected in the serum of two patients. No genetic causes were found. CONCLUSIONS: The common features in the eight patients with unilateral negative ERGs suggest a new disease entity of unilateral acute inner retinal layer dysfunction. In most patients, the only subjective complain was photophobia.

    英語, 研究論文(学術雑誌), PURPOSE: This study aimed to demonstrate the clinical course of Japanese patients with macular telangiectasia type 2 (MacTel-2). METHODS: This retrospective observational case series included 16 eyes of 8 Japanese patients (3 men and 5 women) with MacTel-2. The mean age and follow-up duration was 66.9 years and 42.8 months, respectively. Differences in best-corrected visual acuity (BCVA), funduscopic macular findings, central macular thickness (CMT), and the length of macular ellipsoid zone (EZ) loss were compared between the initial/baseline and final visits. Optical coherence tomographic changes in CMT by ≥ 20% and in EZ loss by ≥ 20% or ≥ 100 μm were defined as improved or worsened. RESULTS: Numerical changes in BCVA and EZ loss during follow-up were not statistically significant. However, the mean CMT at baseline, which was lower than that of healthy control eyes (P < 0.001), significantly increased during follow-up (P = 0.041). A certain proportion of eyes showed improvement in several parameters: funduscopic findings (both parafoveal retinal graying and foveal retinal pigment epithelium depigmentation) in 29% of eyes, CMT in 21% of eyes, and EZ loss in 43% of eyes. CONCLUSIONS: The non-negligible proportion of eyes with improved parameters, marked especially by macular EZ loss, suggests that Japanese patients with MacTel-2 have milder clinical features than Caucasian patients reported in the literature.

    英語, 研究論文(学術雑誌), PURPOSE: To evaluate the relationship between diabetic eyes without diabetic retinopathy and healthy eyes in subfoveal choroidal thickness. DESIGN: Systematic review and meta-analysis. METHODS: An independent retrospective or prospective clinical study comparing diabetic eyes without diabetic retinopathy and healthy control eyes in the subfoveal choroidal thickness was selected. This study compiled data from publications in PubMed and Web of Science between January 1, 2008, and November 15, 2019. Heterogeneity was statistically quantified by I2 statistics, and meta-analysis was performed using a random-effects model. RESULTS: Seventeen related studies were identified, including a total of 4,213 eyes, which consisted of 1,197 diabetic eyes without diabetic retinopathy and 3,016 healthy eyes. Meta-analysis clearly showed that the subfoveal choroidal thickness of diabetic eyes without retinopathy was significantly thinner than that of healthy control eyes (weighted mean difference = -14.34 μm; 95% confidence interval: -24.37 to -4.32 μm; P < .005). Similar results were obtained in sub-analysis based on the adjustment of the axial length. CONCLUSIONS: This study suggests that the subfoveal choroidal thickness was thin in diabetic eyes without retinopathy compared to healthy eyes. Subfoveal choroidal thickness might be an important parameter for the development of diabetic retinopathy in diabetic eyes without retinopathy.

    Retinal cases & brief reports, 2020年08月31日, [国際誌]
    英語, 研究論文(学術雑誌), PURPOSE: To report outer retinal abnormalities evaluated using high-resolution imaging modalities in a patient with Danon disease. METHODS: Case report. RESULTS: A 26-year-old woman, diagnosed with Danon disease based on genetic testing, was referred to our department for further evaluation of ocular findings. Her best-corrected visual acuity was 20/20, and color vision was normal. Fundus examination revealed pigmentary changes consisting of mottled depigmentation and pigmentation in the peripheral retina of both eyes. Spectral-domain optical coherence tomography (SD-OCT) revealed disruptions of the ellipsoid and interdigitation zones, irregularity of the retinal pigment epithelium (RPE), and hyperreflectivity of the outer nuclear layer. In addition, an adaptive optics retinal camera demonstrated the ambiguous macular cone mosaic pattern. CONCLUSION: Danon disease is caused by a primary deficiency in lysosomal associated membrane protein 2 (LAMP-2), an important constituent of the lysosomal membrane that plays a crucial role in the process of autophagy. It is possible that the findings of SD-OCT and adaptive optics retinal camera are early changes associated with the accumulation of autophagosomes and/or phagosomes due to LAMP-2 dysfunction in the photoreceptors, eventually followed by outer retinal degeneration, such as thinning of both the photoreceptor and RPE layers at the fovea.

    Journal of clinical medicine, 9, 8, 2020年07月22日, [国際誌]
    英語, 研究論文(学術雑誌), The receptor-associated prorenin system (RAPS) is associated with several pathologic conditions, including diabetic retinopathy, age-related macular degeneration, and uveitis. Here, we show the involvement of RAPS in the trabecular meshwork (TM) from patients with primary open-angle glaucoma (POAG) and neovascular glaucoma (NVG) due to proliferative diabetic retinopathy. Anterior chamber (AC) levels of prorenin significantly increased in both POAG and NVG, as did those of angiotensin II in NVG alone, compared to cataract. In surgically excised TM tissues, (pro)renin receptor ((P)RR) and angiotensin II type 1 receptor (AT1R) co-localized with prorenin and angiotensinogen, respectively. In screening for various genes related to glaucoma, prorenin stimulation to human TM cells exclusively upregulated cell junction constituents connexin 43 and zona occludens 1, while downregulating an extracellular matrix-degrading enzyme tissue plasminogen activator, all of which were reversed by (P)RR blockade. In contrast, angiotensin II application upregulated a pro-angiogenic factor placental growth factor alone, which was abolished by AT1R blockade. Consistently, (P)RR and AT1R co-localized with these corresponding proteins in patient TM tissues. Oxidative stress, a known etiology for glaucoma, induced the expression of prorenin and angiotensinogen in human TM cells. These data suggest the contribution of RAPS to the molecular pathogenesis of POAG and NVG through TM tissue remodeling and AC angle angiogenesis.

    Journal of clinical medicine, 9, 7, 2020年07月15日, [国際誌]
    英語, 研究論文(学術雑誌), Neovascular age related macular degeneration (nAMD) leads to severe vision loss worldwide and is characterized by the formation of choroidal neovascularization (CNV) and fibrosis. In the current study, we aimed to investigate the effect of blockade for platelet derived growth factor receptor-β (PDGFR-β) on the formation of choroidal neovascularization and fibrosis in the laser-induced CNV model in mice. Firstly, the presence of PDGFR-β in CNV lesions were confirmed. Intravitreal injection of PDGFR-β neutralizing antibody significantly reduced the size of CNV and subretinal fibrosis. Additionally, subretinal hyperreflective material (SHRM), a landmark feature on OCT as a risk factor for subretinal fibrosis formation in nAMD patients was also suppressed by PDGFR-β blockade. Furthermore, pericytes were abundantly recruited to the CNV lesions during CNV formation, however, blockade of PDGFR-β significantly reduced pericyte recruitment. In addition, PDGF-BB stimulation increased the migration of the rat retinal pericyte cell line, R-rPCT1, which was abrogated by the neutralization of PDGFR-β. These results indicate that blockade of PDGFR-β attenuates laser-induced CNV and fibrosis through the inhibition of pericyte migration.
  • A Case of IgG4-Related Ophthalmic Disease With Coronary Arteritis.

    Ophthalmic plastic and reconstructive surgery, 2020年07月13日, [国際誌]
    英語, 研究論文(学術雑誌), IgG4-related disease (IgG4-RD) is a fibro-inflammatory condition characterized by lymphoplasmacytic infiltrates rich in IgG4-positive plasma cells, often with elevated serum IgG4. Multiple organs may be affected. Coronary arteritis may be one form of fatal involvement in IgG4-RD. IgG4-RD can manifest as periocular lesions, called IgG4-related ophthalmic disease (IgG4-ROD). Here, the authors describe a patient with asymptomatic coronary arteritis detected after the diagnosis of IgG4-ROD. A 58-year-old male complained of eyelid swelling and diplopia without systemic symptoms. Swelling of bilateral lacrimal glands and infraorbital nerves, high serum IgG4 levels, and histopathology of lacrimal gland tissue fulfilled diagnostic criteria for IgG4-ROD. After diagnosis, systemic and coronary CT showed coronary lesions and coronary artery stenosis. After prednisolone at 40 mg/day was administered, swelling of the lacrimal glands, diplopia, and coronary lesions improved. This case emphasizes the importance of systemic screening, even if initial symptoms are solely associated with periocular regions.
  • Multimodal imaging in sclerochoroidal calcification: a case report and literature review.
    Mizuho Mitamura, Satoru Kase, Susumu Ishida
    BMC ophthalmology, 20, 1, 248, 248, 2020年06月22日, [国際誌]
    英語, 研究論文(学術雑誌), BACKGROUND: Sclerochoroidal calcification (SCC), a rare condition found in elderly people, is idiopathic or occasionally secondary to disorders affecting calcium metabolism. Findings of multimodal imaging including choroidal circulation are, however, largely unknown. We present a patient of SCC with systemic background, who underwent multimodal imaging evaluations. CASE PRESENTATION: A 70-year-old Japanese man was referred to our clinic because of bilateral fundus lesions. He had a history of chronic kidney disease (CKD) and secondary hyperparathyroidism. Fundus photography showed a cluster of choroidal folds in the superotemporal extra-macular region OS. Swept-source optical coherence tomography demonstrated ellipsoid zone disruption OD, retinal pigment epithelium undulation OS, dilated Haller layer veins OU, and central choroidal thickening OU and thinning of the overlying choroid due to scleral elevation OS. Fluorescein angiography detected macular hyperfluorescence OD. Indocyanine green angiography demonstrated choroidal vascular hyperpermeability together with numerous scattered hypofluorescent lesions OU. Fundus autofluorescence showed multiple hypoautofluorescent spots surrounded by hyperautofluorescent areas OD. Laser speckle flowgraphy exhibited choroidal blood flow reduction represented by a cold color pattern OU. B-mode echography displayed hyperechoic solid lesions with acoustic shadowing and orbital computed tomography revealed high density areas in the sclera, both of which were consistent with calcification. The patient was diagnosed with SCC, and these imaging findings remained unchanged 7 months after the diagnosis. CONCLUSIONS: We reported a case of SCC with the background of CKD. Our detailed multimodal observations indicated choroidal hypoperfusion possibly caused by mechanical compression due to calcium deposition in the sclera.
  • Regulation of Spermine Oxidase through Hypoxia-Inducible Factor-1α Signaling in Retinal Glial Cells under Hypoxic Conditions.

    Investigative ophthalmology & visual science, 61, 6, 52, 52, 2020年06月03日, [国際誌]
    英語, 研究論文(学術雑誌), Purpose: Acrolein, a highly reactive unsaturated aldehyde, is known to facilitate glial cell migration, one of the pathological hallmarks in diabetic retinopathy. However, cellular mechanisms of acrolein generation in retinal glial cells remains elusive. In the present study, we investigated the role and regulation of spermine oxidase (SMOX), one of the enzymes related to acrolein generation, in retinal glial cells under hypoxic condition. Methods: Immunofluorescence staining for SMOX was performed using sections of fibrovascular tissues obtained from patients with proliferative diabetic retinopathy. Expression levels of polyamine oxidation enzymes including SMOX were analyzed in rat retinal Müller cell line 5 (TR-MUL5) cells under either normoxic or hypoxic conditions. The transcriptional activity of Smox in TR-MUL5 cells was evaluated using the luciferase assay. Levels of acrolein-conjugated protein, Nε-(3-formyl-3,4-dehydropiperidino) lysine adduct (FDP-Lys), and hydrogen peroxide were measured. Results: SMOX was localized in glial cells in fibrovascular tissues. Hypoxia induced SMOX production in TR-MUL5 cells, which was suppressed by silencing of hypoxia-inducible factor-1α (Hif1a), but not Hif2a. Transcriptional activity of Smox was regulated through HIF-1 binding to hypoxia response elements 2, 3, and 4 sites in the promoter region of Smox. Generation of FDP-Lys and hydrogen peroxide increased in TR-MUL5 cells under hypoxic condition, which was abrogated by SMOX inhibitor MDL72527. Conclusions: The current data demonstrated that hypoxia regulates production of SMOX, which plays a role in the generation of oxidative stress inducers, through HIF-1α signaling in Müller glial cells under hypoxic condition.

    英語, 研究論文(学術雑誌), PURPOSE: The aim of this study was to analyze choroidal structures in healthy subjects and patients with/without diabetic macular edema (DME). METHODS: This was a retrospective observation case control study. Four hundred and two eyes of patients with diabetes mellitus (DM), and 124 age-matched eyes of healthy subjects were enrolled in this study. DM patients were divided into 3 groups: presence of central-involved (CI) DME (n = 81) and nonCI-DME/non-DME (n = 321), based on OCT findings. Central choroidal thickness (CCT) and total choroidal, luminal, and stromal areas were determined using EDI-OCT and a binarization method, respectively. The luminal area expressed as a ratio of the total choroidal area was defined as the L/C ratio. RESULTS: DM eyes showed a significantly lower L/C ratio than control eyes, whereas there was no significant difference in CCT or total choroidal, luminal, or stromal areas. There was no significant difference between CI-DME and non-DME groups in HbA1c, blood pressure, dyslipidemia, or renal function. CCT and total choroidal, luminal, and stromal areas were significantly greater in the CI-DME group than non-DME group (each P < 0.05). CONCLUSIONS: These results suggest that CCT was thickened in the presence of DME, associated with both increased luminal and stromal areas, which might be related to the pathology of DME.

    英語, 研究論文(学術雑誌), BACKGROUND: Evidence-based criteria for the treatment of autoimmune retinopathy (AIR) have not been established. The pathology and clinical features of each antibody causing AIR, and its long-term course are still undetermined. We report our findings in a case of non-paraneoplastic AIR (npAIR) that developed in the fellow eye 10 years after the onset in the first eye. CASE PRESENTATION: Our patient had photophobia in both eyes and a rapidly progressing visual field defect in his right eye at the initial examination. He was diagnosed with non-paraneoplastic AIR based on the clinical findings and immunoblot analyses for anti-retinal antibodies, and he was treated with steroids. Ten years later, a visual field defect developed in the fellow eye, and a diagnosis of npAIR was made. Immunoblot analyses were positive for anti-α-enolase antibodies. He was treated with steroids, immunosuppressants, and plasma exchange. However, the response to the treatment was poor and both eyes eventually became blind. CONCLUSIONS: As best we know, this is the first case report of npAIR that developed in the fellow eye over 10 years after the development in the first eye. Long-term follow-up and a search for tumor lesions are necessary in cases of npAIR. Further understanding of the long-term course of AIR can contribute to an understanding of the pathology and treatment of npAIR.

    英語, 研究論文(学術雑誌), Galectin-1/LGALS1, a newly recognized angiogenic factor, contributes to the pathogenesis of diabetic retinopathy (DR). Recently, we demonstrated that glucocorticoids suppressed an interleukin-1β-driven inflammatory pathway for galectin-1 expression in vitro and in vivo. Here, we show glucocorticoid-mediated inhibitory mechanism against hypoxia-inducible factor (HIF)-1α-involved galectin-1 expression in human Müller glial cells and the retina of diabetic mice. Hypoxia-induced increases in galectin-1/LGALS1 expression and promoter activity were attenuated by dexamethasone and triamcinolone acetonide in vitro. Glucocorticoid application to hypoxia-stimulated cells decreased HIF-1α protein, but not mRNA, together with its DNA-binding activity, while transactivating TSC22 domain family member (TSC22D)3 mRNA and protein expression. Co-immunoprecipitation revealed that glucocorticoid-transactivated TSC22D3 interacted with HIF-1α, leading to degradation of hypoxia-stabilized HIF-1α via the ubiquitin-proteasome pathway. Silencing TSC22D3 reversed glucocorticoid-mediated ubiquitination of HIF-1α and subsequent down-regulation of HIF-1α and galectin-1/LGALS1 levels. Glucocorticoid treatment to mice significantly alleviated diabetes-induced retinal HIF-1α and galectin-1/Lgals1 levels, while increasing TSC22D3 expression. Fibrovascular tissues from patients with proliferative DR demonstrated co-localization of galectin-1 and HIF-1α in glial cells partially positive for TSC22D3. These results indicate that glucocorticoid-transactivated TSC22D3 attenuates hypoxia- and diabetes-induced retinal glial galectin-1/LGALS1 expression via HIF-1α destabilization, highlighting therapeutic implications for DR in the era of anti-vascular endothelial growth factor treatment.

    英語, 研究論文(学術雑誌), BACKGROUND/AIM: CD38 is a cell surface marker commonly present in plasma cells and activated T cells, while CD138 is a representative plasma cell marker. The aim of this study was to describe the expression of cell surface markers including CD38 and CD138, in the tumors of patients with IgG4-related ophthalmic disease (IgG4-ROD) and extranodal marginal zone B-cell lymphoma (EMZL) of the ocular adnexa. MATERIALS AND METHODS: Twenty-four consecutive patients of whom 12 had IgG4-ROD and 12 EMZL were enrolled in this study. Medical records were reviewed for flow cytometry (FCM) results on conventional T-cell markers, B-cell markers, CD38 and CD138. RESULTS: Positive rates of T-cell markers, CD38 and CD138 were significantly higher in IgG4-ROD than in EMZL (p<0.01 and p<0.05, respectively). CONCLUSION: Our FCM results on CD38 and CD138 showed that the lymphocyte populations were different between IgG4-ROD and EMZL, which may reflect the different pathophysiology of the two diseases.

    英語, 研究論文(学術雑誌), BACKGROUND: Hematologic malignancies occasionally cause serous retinal detachment (SRD); however, its pathogenesis remains unclear. Here we present the imaging characteristics of metastatic choroidal lymphoma masquerading as Vogt-Koyanagi-Harada (VKH) disease. CASE PRESENTATION: A 45-year-old Japanese woman was referred to our clinic because of bilateral SRD with blurred vision. Fluorescein angiography revealed multiple pinpoint leakage followed by pooling OU. Enhanced depth imaging optical coherence tomography showed marked choroidal thickening OU. Laser speckle flowgraphy detected choroidal circulation impairment OU. Although these results totally agreed with the inflammatory manifestations of acute VKH disease, indocyanine green angiography demonstrated various sizes of sharply marginated hypofluorescent lesions that seemed atypical for the finding of VKH disease, i.e., vaguely marginated hypofluorescent small dots. Cerebrospinal fluid pleocytosis was not detected. Blood tests revealed leukocytosis together with elevation of lactate dehydrogenase and soluble interleukin-2 receptor levels. Corticosteroid pulse therapy did not improve any ocular findings. Bone marrow biopsy was then performed, leading to a definite diagnosis of diffuse large B-cell lymphoma. After starting systemic chemotherapy, both SRD and choroidal thickening resolved rapidly with visual recovery. However, choroidal hypoperfusion persisted, which contrasted distinctly with the inflammatory pattern of VKH disease, i.e., the restoration of choroidal blood flow in parallel with normalization of choroidal thickness. CONCLUSIONS: Our detailed multimodal observations highlighted the differential imaging features of choroidal lymphoma despite close resemblance to VKH disease especially at the initial stage. Impaired circulation in the thickened choroid marked the pseudo-inflammatory pathogenesis of SRD due to choroidal involvement with neoplastic, but not inflammatory cells.

    英語, 研究論文(学術雑誌), PURPOSE: The aim of this study was to analyse choroidal structures in normal patients and patients with diabetes with various severities of diabetic retinopathy (DR). METHODS: This is a retrospective observation case control study. Three hundred and forty-two diabetic eyes, and age-matched 112 eyes without diabetes mellitus (DM) were enrolled in this study. Patients with DM were classified into no DR, mild/moderate non-proliferative DR (mNPDR), severe NPDR and proliferative DR (PDR). Patients with DM were further divided into two groups based on information regarding systemic DM treatment situation: DM-treated and untreated groups. Central choroidal thickness (CCT), and total choroidal area (TCA), luminal area (LA) and stromal area (SA) were determined using enhanced depth imaging optical coherence tomography and a binarisation method, respectively. The ratio of LA in the TCA was defined as L/C ratio. RESULTS: The haemoglobin A1c (HbA1c) value was significantly higher in the DM-untreated than in the DM-treated subjects. L/C ratio was significantly lower in all the diabetic eyes than control eyes (p<0.05). TCA, LA, L/C ratio and CCT were significantly greater in the DM-untreated than treated group (each p<0.05). In the DM-untreated group, TCA and LAs (p<0.05) and L/C ratio (p<0.01) were significantly lower in mNPDR subjects than normal controls (p<0.05). PDR in the DM-untreated group showed significantly larger SA and LA, and greater CCT than normal controls (each p<0.05). CONCLUSIONS: These results suggest that choroidal vasculature was initially involved at an early DR, whereas thickened LA and SA were noted in advanced DR.

    英語, 研究論文(学術雑誌), PURPOSE: To investigate the alterations of central choroidal thickness (CCT) and macular choroidal blood flow in patients with hypertensive chorioretinopathy treated with antihypertensive agents. METHODS: In retrospective observational case series, ten eyes of 9 patients with hypertensive chorioretinopathy were enrolled (5 men and 4 women; 43.1 ± 19.6 years of age). CCT and mean blur rate (MBR) had been observed during follow-up using enhanced depth imaging optical coherence tomography and laser speckle flowgraphy, respectively. RESULTS: With the medication for hypertension, serous retinal detachment (SRD) disappeared in all the eyes (mean period, 57.8 ± 50.4 days), and the mean blood pressure decreased (122.7 ± 13.0 mmHg and 93.4 ± 13.2 mmHg at the initial visit and at the day of subretinal fluid absorption, respectively; P < 0.01). The mean logMAR value of best corrected visual acuity showed a tendency toward improvement with the resolution of SRD (0.15 ± 0.30 and 0.08 ± 0.28, P = 0.15). The average MBR significantly decreased when SRD was absorbed (11.4 ± 4.5 and 7.7 ± 2.2, P < 0.01). Similarly, the mean values of CCT decreased (473.2 ± 218.0 μm and 325.7 ± 112.0 μm, P < 0.01). The changing rates of CCT and MBR showed a significant positive correlation (P < 0.01, R = 0.88). CONCLUSION: The current study demonstrated a novel finding that choroidal blood flow velocity and thickness concurrently increased in the acute phase of hypertensive chorioretinopathy, suggesting the role of choroidal hyperperfusion in the pathogenesis of hypertensive chorioretinopathy.

    英語, 研究論文(学術雑誌), With increasing prevalence of diabetes and a progressively aging society, diabetic retinopathy is emerging as one of the global leading causes of blindness. Recent studies have shown that vascular endothelial growth factor (VEGF) plays a central role in the pathogenesis of diabetic retinopathy and anti-VEGF agents have become the first-line therapy for the vision-threatening disease. However, recent studies have also demonstrated that diabetic retinopathy is a multifactorial disease and that VEGF-independent mechanism(s) also underlie much of the pathological changes in diabetic retinopathy. Acrolein is a highly reactive unsaturated aldehyde and is implicated in protein dysfunction. As acrolein is common in air pollutants, previous studies have focused on it as an exogenous causative factor, for instance, in the development of respiratory diseases. However, it has been discovered that acrolein is also endogenously produced and induces cell toxicity and oxidative stress in the body. In addition, accumulating evidence suggests that acrolein and/or acrolein-conjugated proteins are associated with the molecular mechanisms in diabetic retinopathy. This review summarizes the pathological roles and mechanisms of endogenous acrolein production in the pathogenesis of diabetic retinopathy.

    英語, 研究論文(学術雑誌), Glaucoma is characterized by axonal degeneration of retinal ganglion cells (RGCs) and apoptotic death of their cell bodies. Lowering intraocular pressure is currently the only way to treat glaucoma, but it is often insufficient to inhibit the progression of the disease. Glaucoma is a multifactorial disease, and the involvement of oxidative stress has recently received much attention. In the present study, we investigated the cytoprotective effect of astaxanthin (AST) on RGC degeneration using a normal-tension glaucoma (NTG) mouse model, which lacks the glutamate/aspartate transporter (Glast) and demonstrates spontaneous RGC and optic nerve degeneration without elevated intraocular pressure. Three-week-old Glast± mice were given intraperitoneal injections of AST at 10, 30, or 60 mg/kg/day or vehicle alone, and littermate control mice were given vehicle alone for 14 days, respectively. Five weeks after birth, the number of RGCs was counted in paraffin sections of retinal tissues stained with hematoxylin and eosin. We also used a retrograde labeling technique to quantify the number of RGCs. Additionally, the phosphorylated (p) IκB/total IκB ratio and the 4-hydroxynonenal (HNE) were measured in retinal tissues. The number of RGCs in Glast± mice was significantly decreased compared with that in control mice. RGC loss was suppressed by the administration of AST at 60 mg/kg/day, compared with vehicle alone. Following AST administration, the concentration of 4-HNE in the retina was also suppressed, but the pIκB/IκB ratio did not change. Our study revealed that the antioxidative stress effects of AST inhibit RGC degeneration in the retina and may be useful in the treatment of NTG.

    英語, 研究論文(学術雑誌), PURPOSE: To investigate the relationship between diabetic macular edema (DME) and the choroidal layer thickness in diabetic patients. METHODS: This is a retrospective observation study. Three hundred eighteen eyes of 159 diabetes mellitus (DM) patients and age-matched 100 eyes of 79 healthy controls were enrolled. DME was defined as over 300 μm in the central retinal subfield of the Early Treatment Diabetic Retinopathy Study (ETDRS) grid sector. The central choroidal thickness (CCT), as well as inner and outer layers were determined based on enhanced depth imaging (EDI)-OCT. Diabetic patients with/without systemic diabetic treatments (DT) at the start of this study was defined as DT+ and DT-, respectively. The number of eyes examined was 62 and 256 eyes in DME+and DME-groups, respectively. DM patients were further subdivided into 4 groups with/without DME and DT; DME+DT+(35 eyes), DME-DT+(159 eyes), DME+DT-(27 eyes), and DME-DT-group (97 eyes). Multiple comparisons on CCT layers including control and each DM group were statistically examined. RESULTS: The total CCT layer was 254±83, 283±88, and 251±70 μm in the control, DME+, and DME-group, respectively. A total CCT layer in DME+was significantly thicker than the DME-group (P < 0.05). The outer CCT layer was 195±75, 222±83, and 193±63 μm in the control, DME+, and DME-group, respectively. The outer CCT layer in DME+ was significantly thicker than the DME-group (P < 0.05). In the subdivided groups, the total CCT layers in the control, DME+DT+, DME-DT+, DME+DT-and DME-DT-groups were 254±83, 274±88, 247±66, 290±84 and 258±75 μm, respectively. The outer CCT layers in each group were 195±75, 214±83, 189±58, 228±77, and 201±70 μm, respectively. Total CCT and the outer layer in DME+DT-was significantly thicker than the DME-DT+group (each P < 0.05). In contrast, there was no significant difference in inner layer between the groups. CONCLUSIONS: The total and outer CCT layers of diabetic eyes were significantly thickened in the DME+DT-as compared with the DME-DT+group, suggesting that CCT may be related to the pathology of DME.

    英語, 研究論文(学術雑誌), Spontaneously Diabetic Torii (SDT) fatty rat is a novel animal model of type 2 diabetes with obesity. SDT fatty rats develop hyperglycemia, dyslipidemia, and other diabetic complications including ocular disorders; however, diabetic cataract formation in SDT fatty rats has not been fully investigated. The aim of the current study was to investigate the characteristics of cataract in the SDT fatty rats. The mean body weight of SDT fatty rats is larger than that of age-matched Sprague-Dawley (SD) rats and control animals until 8 weeks of age, and thereafter the growing speed decreased until the end of observation at 16 weeks of age. Blood glucose levels in SDT fatty rats were significantly higher than those in SD rats throughout the observational period. Slit-lamp examination revealed that no rats showed cataract formation at 5 weeks of age; however, SDT fatty rats gradually developed cortical cataract and posterior subcapsular cataract, both of which are the common types of cataract in patients with type 2 diabetes. The levels of glucose, sorbitol, and fructose were higher in the lens tissues of SDT fatty rats in comparison with that of SD rats. Furthermore, the level of 4-hydroxynonenal (4-HNE) was higher in the lens of SDT fatty rats than in that of SD rats. By contrast, total glutathione (GSH) concentration was lower in the lens of SDT fatty rats than in that of SD rats. The present study demonstrated that the cataractogenesis in SDT fatty rats resembled human diabetic cataract formation, indicating that SDT fatty rats serve as a potential animal model in researches on human cataract associated with type 2 diabetes and obesity.

    英語, Purpose: The aim of this study was to analyze immunohistochemical and immunocytological findings by examining enucleated eyes and vitreous cell block (CB) in patients with vitreoretinal lymphoma (VRL).Methods: Histological specimens were obtained from two enucleated eyes with VRL associated with neovascular glaucoma. CB specimens were prepared in 18 patients from diluted waste fluids containing shredded vitreous. Histological and cytological specimens were submitted for hematoxylin-eosin staining and immunopathological analyses.Results: Both specimens demonstrated massive infiltration of large lymphoma cells. The lymphoma cells were positive for CD20 and MUM-1 in enucleated eyes. Membranous immunoreactivity for CD20 was observed in lymphoma cells in CB with VRL. Bcl-6 and MUM-1 were marked in five and eight out of nine cases examined, respectivelyConclusions: Cytological findings in CB specimens indicated similar histopathological characteristics of enucleated eyes. CB specimens obtained from vitreous waste diluted fluids may serve as effective materials for cytological diagnosis of VRL.

    英語, 研究論文(学術雑誌), BACKGROUND: We report a rare case of sudden bilateral vision loss due to third ventricular cavernous angioma with intratumoral hemorrhage. CASE PRESENTATION: A 45-year-old woman presented decreased visual acuity in both eyes. Her best corrected visual acuity was 0.1 in the right eye and 0.15 in the left eye. Goldmann perimetry showed bilateral central scotomas and bitemporal visual field defects. MRI demonstrated a lesion with mixed hypo- and hyperintensity at the optic chiasm, which was thought to be an intratumoral hemorrhage. The patient underwent bifrontal craniotomy. The tumor was exposed via an anterior interhemispheric approach, and histological evaluation of the mass led to a diagnosis of cavernous angioma. Six months after the surgery, her best corrected visual acuity was 0.9 in the right eye and 0.9 in the left, with slight bitemporal visual field defects. CONCLUSION: Third ventricular cavernous angioma is considered in the differential diagnosis of chiasmal syndrome. Contrast-enhanced MRI and FDG-PET might be useful for differential diagnosis of cavernous angioma from other chiasmal tumors including glioblastoma.

  • Glucocorticoid receptor inhibits Müller glial galectin-1 expression via DUSP1-dependent and -independent deactivation of AP-1 signalling.
    Ikuyo Hirose, Atsuhiro Kanda, Kousuke Noda, Susumu Ishida
    Journal of cellular and molecular medicine, 23, 10, 6785, 6796, 2019年10月, [国際誌]
    英語, 研究論文(学術雑誌), Galectin-1/LGALS1 is a hypoxia-induced angiogenic factor associated with diabetic retinopathy (DR). Recently, we elucidated a hypoxia-independent pathway to produce galectin-1 in Müller glial cells stimulated by interleukin (IL)-1β. Here we revealed glucocorticoid receptor (GR)-mediated inhibitory mechanisms for Müller glial galectin-1/LGALS1 expression. Activator protein (AP)-1 site in the LGALS1 enhancer region, to which activating transcription factor2, c-Fos and c-Jun bind, was shown to be essential for IL-1β-induced galectin-1/LGALS1 expression in Müller cells. Ligand (dexamethasone or triamcinolone acetonide)-activated GR induced dual specificity phosphatase (DUSP)1 expression via the glucocorticoid response element and attenuated IL-1β-induced galectin-1/LGALS1 expression by reducing phosphorylation of these AP-1 subunits following AKT and extracellular signal-regulated kinase (ERK)1/2 deactivation. Moreover, activated GR also caused DUSP1-independent down-regulation of IL-1β-induced LGALS1 expression via its binding to AP-1. Administration of glucocorticoids to mice attenuated diabetes-induced retinal galectin-1/Lgals1 expression together with AKT/AP-1 and ERK/AP-1 pathways. Supporting these in vitro and in vivo findings, immunofluorescence analyses showed co-localization of galectin-1 with GR and phosphorylated AP-1 in DUSP1-positive glial cells in fibrovascular tissues from patients with DR. Our present data demonstrated the inhibitory effects of glucocorticoids on glial galectin-1 expression via DUSP1-dependent and -independent deactivation of AP-1 signalling (transactivation and transrepression), highlighting therapeutic implications for DR.
  • Unsaturated Aldehyde Acrolein Promotes Retinal Glial Cell Migration.

    Investigative ophthalmology & visual science, 60, 13, 4425, 4435, 2019年10月01日, [国際誌]
    英語, 研究論文(学術雑誌), Purpose: To investigate the effect of the unsaturated aldehyde acrolein on retinal glial cell migration. Methods: Müller glial cell markers expression in TR-MUL5 were confirmed by RT-PCR and immunostaining. Cell viability and migration rate of TR-MUL5 cells were assessed after the stimulation with acrolein. DNA microarray analysis was performed to analyze changes in the expression levels of migration-related genes in Müller glial cells stimulated with acrolein. Real-time PCR and ELISA were performed to validate DNA microarray analysis results. Inhibitors of C-X-C motif chemokine ligand 1 (CXCL1), one of the genes highly upregulated after the exposure to acrolein, and blockers of its receptor, CXCR2, were used to investigate the role of the CXCL1-CXCR2 axis on glial cell migration. CXCL1 concentration was measured in vitreous fluid samples obtained from proliferative diabetic retinopathy (PDR) and nondiabetic control eyes. CXCL1 and CXCR2 expression in glial cells of fibrovascular tissues obtained from PDR patients was examined by immunostaining. Results: At a high concentration, acrolein (100 μM) significantly decreased cell viability. However, in moderate, sublethal concentrations (25-50 μM), acrolein induced cell migration and substantially increased the production of CXCL1 in TR-MUL5 cells. CXCL1 concentration was significantly elevated in vitreous fluids of PDR patients, and CXCL1 and CXCR2 were present in glial cells in fibrovascular tissues of PDR patients. CXCL1 stimulation increased glial cell migration in a dose-dependent manner, which was abrogated by the neutralization of the CXCL1-CXCR2 axis. Conclusions: Our data demonstrate that acrolein promotes retinal Müller glial cell migration by enhancing CXCL1 production.

    英語, 研究論文(学術雑誌), The receptor-associated prorenin system refers to the pathogenic mechanism whereby prorenin binding to (pro)renin receptor [ (P)RR] dually activates the tissue renin-angiotensin system (RAS) and RAS-independent signaling, and its activation contributes to the molecular pathogenesis of various ocular diseases. We recently developed a new single-stranded RNAi agent targeting both human and mouse (P)RR ((P)RR-proline-modified short hairpin RNA [ (P)RR-PshRNA]), and confirmed its therapeutic effect on murine models of ocular inflammation. Here, we investigated the efficacy of (P)RR-PshRNA against laser-induced choroidal neovascularization (CNV) and subretinal fibrosis, both of which are involved in the pathogenesis of age-related macular degeneration (AMD). Administration of (P)RR-PshRNA in mice significantly reduced CNV formation, together with the expression of inflammatory molecules, macrophage infiltration, and extracellular signal-regulated kinase (ERK) 1/2 activation. In addition, (P)RR-PshRNA attenuated subretinal fibrosis, together with epithelial-mesenchymal transition (EMT)-related markers including phosphorylated SMAD2. The suppressive effect of (P)RR-PshRNA is comparable with aflibercept, an anti-vascular endothelial growth factor drug widely used for AMD therapy. AMD patient specimens demonstrated (P)RR co-localization with phosphorylated ERK1/2 in neovascular endothelial cells and retinal pigment epithelial cells. These results indicate that (P)RR contributes to the ocular pathogenesis of both inflammation-related angiogenesis and EMT-driven fibrosis, and that (P)RR-PshRNA is a promising therapeutic agent for AMD.

    英語, 研究論文(学術雑誌), PURPOSE: To compare the clinical characteristics of Vogt-Koyanagi-Harada (VKH) disease patients with and without anti-retinal antibodies (ARAs) that are frequently detected in autoimmune retinopathy. METHODS: Using immunoblot analyses, serum autoantibodies for recoverin, carbonic anhydrase II, and α-enolase were examined in 20 treatment-naïve patients with VKH disease. Clinical factors before and after systemic corticosteroid therapy, including best-corrected visual acuity (BCVA) and macular outer retinal morphology, were statistically compared between patients with VKH disease with and without ARAs. RESULTS: Serum ARAs were detected in 50.0% of patients with VKH disease. There were no significant differences in clinical factors between the two groups, including final BCVA, frequency of uveitis recurrence, and recovery of the macular ellipsoid zone after systemic corticosteroid therapy. CONCLUSIONS: Our results suggest that the detected ARAs did not influence visual outcomes, the chronicity of uveitis, or outer retinal morphology in patients with VKH disease.

    英語, 研究論文(学術雑誌), BACKGROUND: The aim of this study was to evaluate the relationship between the choroidal structure of diabetic patients without diabetic retinopathy (DR) and duration of diabetes. METHODS: This study is a retrospective observational study in diabetic patients without DR. Eyes with diabetes mellitus (DM) (n = 105) were divided into two groups based on the duration: long duration group (over 10 years, n = 31) and short duration group (less than 10 years, n = 74). One hundred seventeen eyes of non-diabetic patients were used as control group. All patients underwent enhanced depth imaging optical coherence tomography, and the choroidal structure was analyzed using a binarization method. RESULTS: There was no significant difference in areas of total choroid and lumina/stroma or central choroidal thickness (CCT) between control and DM groups. In contrast, lumina/total choroidal (L/C) ratio was significantly lower in diabetic eyes than in control eyes (P = 0.02). Although there was no significant difference in the areas or CCT between short and long duration groups, L/C ratio was significantly lower in the long duration group than in the short duration group (P = 0.03). CONCLUSIONS: The current study suggests that choroidal vasculature is involved in the diabetic eyes and that the choroidal structure has changed with duration of diabetes. Our study points out that L/C ratio is a new potential biomarker in monitoring choroidal vascular disorders in diabetic eyes without DR.

    英語, Purpose: Relentless placoid chorioretinitis (RPC) is a new disease concept that was proposed by Jones et al. in 2000. Some cases of RPC have been reported; however, a treatment strategy has not yet been established. We report herein four cases of patients diagnosed with RPC. Observations: We experienced four cases of RPC in patients aged 24-51 years. All patients exhibited retinal lesions similar to that seen in acute posterior multifocal placoid pigment epitheliopathy or serpiginous choroiditis from the posterior pole to the surrounding region. Although patients underwent systemic prednisolone (PSL) therapy, recurrence was observed and the retinal scar formation was progressive; they were then diagnosed with RPC. In all cases, cyclosporine (CyA) was administered in addition to PSL, no recurrence was observed thereafter. Conclusions and Importance: RPC is a rare disease, and a treatment strategy has not yet been established. CyA and PSL combination therapy is considered to be effective in the treatment of RPC.

  • Photocoagulation for juxtapapillary retinal hemangioma in a young girl: A case report.
    Satoru Kase, Susumu Ishida
    Molecular and clinical oncology, 10, 5, 521, 523, 2019年05月, [国際誌]
    英語, 研究論文(学術雑誌), von Hippel Lindau (VHL) disease is caused by inactivation of the VHL tumor suppressor gene, resulting in formation of multiple systemic tumors. Juxtapapillary retinal capillary hemangioma (JRCH) is one of the major manifestations in VHL disease; however, treatments are challenging, especially in children. The present study reports the case of a 6-year-old girl with suspected VHL disease presenting with JRCH. Fluorescein angiography demonstrated marked dye leakage from the tumor. Retinal hemorrhage occurred around the tumor 7 months later. Laser photocoagulation of the tumor tissue was safely and successfully conducted without general anesthesia. The hemorrhage diminished after laser photocoagulation. Optical coherence tomography demonstrated mild resolution of an elevated lesion in JRCH with contraction of the vitreoretinal interface over the tumor. Laser photocoagulation may be considered the first-line treatment for young patients with JRCH, although the primary physicians must have the necessary skills and be able to establish good doctor-patient relationships, even with children.

    英語, 研究論文(学術雑誌), PURPOSE: This study aims to examine the relationship between ocular circulation changes and visual field defects in optic disk melanocytoma (ODM). METHODS: Five eyes of five patients were enrolled in this study. All patients were diagnosed with ODM in the Department of Ophthalmology, Hokkaido University Hospital from March 2009 to November 2017. Ophthalmological data including optical coherence tomography angiography (OCTA) and laser speckle flowgraphy (LSFG) findings were retrospectively analyzed. RESULTS: The five ODM cases consisted of two females and three males. Ages of the patients ranged from 47 to 82 years (mean 54 years). Follow-up periods were from 4 to 105 months. Fluorescein angiography showed hypo-fluorescence throughout the examination in all four eyes examined with this modality. OCTA detected dense blood vessel networks in the tumor in two out of the five eyes. Nasal visual field defects were found in two other eyes, which were correlated with locations of tumors free of vessel networks. One ODM eye without marked visual field defects and pigmentations showed lower mean blur rates determined by LSFG in optic disk vessels and tissue circulations than those in the contralateral eye. During follow-up, there was no tumor enlargement in any case. CONCLUSIONS: This study showed the relationship between the deficit of blood vessel networks and visual field defects in ODM patients. LSFG demonstrated reduced blood flow in the tumor, suggesting that circulatory disorder caused by the optic disk tumor might be correlated with visual field defect.

  • Galectin-1 promotes choroidal neovascularization and subretinal fibrosis mediated via epithelial-mesenchymal transition
    Di W, Kanda A, Ye L, Kase S, Noda, K, Ishida S
    FASEB J, 33, 2, 2498, 2513, 2019年02月, [査読有り], [国際誌]
    英語, 研究論文(学術雑誌), VEGFA and TGF-β are known major angiogenic and fibrogenic factors. Galectin-1, encoded by lectin, galactoside-binding, soluble ( LGALS) 1, has attracted growing attention for its facilitatory role in angiogenesis and fibrosis through its modification of VEGFA and TGF-β receptor signaling pathways. We reveal galectin-1 involvement in the mouse model of laser-induced choroidal neovascularization (CNV) and subretinal fibrosis, both of which represent the pathogenesis of age-related macular degeneration (AMD). Neither deletion nor overexpression of Lgals1 affected physiologic retinal development or visual function. Galectin-1/ Lgals1 was upregulated by CNV induction, whereas deletion of Lgals1 suppressed CNV together with downstream molecules of VEGF receptor (VEGFR)2. Loss of Lgals1 also attenuated subretinal fibrosis, expression of epithelial-mesenchymal transition (EMT) markers including Snai1, and phosphorylation of SMAD family member 2. Supporting these in vivo findings, silencing of LGALS1 in human retinal pigment epithelial (RPE) cells inhibited TGF-β1-induced EMT-related molecules and cell motilities. Conversely, overexpression of Lgals1 enhanced CNV and subretinal fibrosis. Specimens from patients with AMD demonstrated colocalization of galectin-1 with VEGFR2 in neovascular endothelial cells and with phosphorylated SMAD2 in RPE cells. These results suggested a biologic significance of galectin-1 as a key promotor for both angiogenesis and fibrosis in eyes with AMD.-Wu, D., Kanda, A., Liu, Y., Kase, S., Noda, K., Ishida, S. Galectin-1 promotes choroidal neovascularization and subretinal fibrosis mediated via epithelial-mesenchymal transition.
  • TGF-β-SNAIL axis induces Müller glial-mesenchymal transition in the pathogenesis of idiopathic epiretinal membrane.

    Scientific reports, 9, 1, 673, 673, 2019年01月24日, [国際誌]
    英語, 研究論文(学術雑誌), The epithelial-mesenchymal transition (EMT) is a key process in fibrogenic diseases where transdifferentiated myofibroblasts produce excessive amounts of extracellular matrix, resulting in organ dysfunction. Idiopathic epiretinal membrane (iERM) is a vision-threatening disorder characterized by fibrocellular proliferation and contraction on the central retina. Müller glial cells, which regulate retinal physiology and structure, are the major cellular components in the iERM tissue; however, the pathological role of this cell type remains incompletely understood. Here we revealed the involvement of Müller glial-mesenchymal transition (GMT), as an alternative to EMT, in the pathogenesis of iERM lacking epithelial contribution in nature. Of various pro-fibrotic cytokines, transforming growth factor (TGF)-β1 stimulation to human Müller glial cells exclusively increased mRNA and protein levels of several EMT-related molecular markers, together with the transcription factor SNAIL but not SLUG or TWIST. TGF-β1-stimulated Müller cells also exhibited EMT-related cell motility, while reducing the expression of glutamine synthetase (GS), a Müller glial marker. Notably, all of these TGF-β-induced EMT features were reversed by SNAI1 knockdown in Müller cells. iERM patient specimens demonstrated co-immunolocalization of SNAIL with TGF-β1, GS, and smooth muscle protein 22. Our data implicated a critical role of the TGF-β-SNAIL axis in Müller GMT to promote iERM formation.

    英語, 研究論文(学術雑誌), PURPOSE: To evaluate corneal tactile and pain sensations in patients with short tear film break-up time dry eye (sBUT DE). METHODS: This study enrolled 60 patients with sBUT DE and 46 healthy volunteers from Japan. We evaluated corneal tactile and pain sensations using a modified method with the Cochet-Bonnet corneal esthesiometer. RESULTS: Patients with sBUT DE had higher corneal pain sensitivity (26.3 ± 23.1 mm) than healthy subjects (6.9 ± 16.4 mm), but similar corneal tactile sensation (52.0 ± 15.5 mm and 52.9 ± 14.9 mm, respectively). In patients with sBUT DE and corneal hyperalgesia (n = 22, 36.7%), defined as a pain sensitivity ≥40 mm (i.e., the cutoff value at the 95th percentile of corneal pain sensitivity in healthy subjects), a strong significant correlation was found between the subjective pain score and objective corneal pain sensation (R = 0.79). However, for the entire cohort, we found a weak positive correlation between the subjective pain score and objective corneal pain sensation. CONCLUSIONS: Patients with sBUT DE were hypersensitive to corneal pain, which suggested that corneal hyperalgesia partly accounted for subjective symptoms in patients with sBUT DE.

  • Involvement of Inner Choroidal Layer in Choroidal Thinning during Regression of Multiple Evanescent White Dot Syndrome.
    Yuki Hashimoto, Wataru Saito, Yuka Hasegawa, Kousuke Noda, Susumu Ishida
    Journal of ophthalmology, 2019, 6816925, 6816925, 2019年, [国際誌]
    英語, 研究論文(学術雑誌), Purpose: To investigate relationships between total thickness and the thickness of inner and outer layers in the choroid during regression in patients with multiple evanescent white dot syndrome (MEWDS). Methods: This retrospective observational case series included 15 unilaterally affected eyes and 13 unaffected fellow eyes from 15 MEWDS patients (4 men and 11 women; mean age, 37.6 ± 17.6 years). Using enhanced depth imaging optical coherence tomography, whole, inner, and outer choroidal layer thicknesses at the fovea and perifovea were manually measured at the initial visit and at 1 and 3 months after the initial visit. The mean thickness values of the layers were compared at each stage. Results: With regression of MEWDS, the mean subfoveal whole and inner choroidal layer thicknesses significantly decreased at 1 and 3 months compared to baseline values in MEWDS eyes (P=0.01 and P < 0.0001, respectively), but not in fellow eyes. The outer layer in MEWDS eyes tended to thin. Changes in the inner and outer layers at the perifovea in MEWDS eyes also showed the same trends. Simple linear regression analysis revealed significant positive correlations in choroidal thickness changes between the whole and inner layers (R = 0.53, P=0.04) and between the whole and outer layers (R = 0.91, P < 0.0001) from baseline to 3 months. Multiple linear regression analysis revealed that choroidal thickness changes in the whole layer were significantly correlated with those in the inner (β = 0.51, P < 0.0001) and outer (β = 0.73, P < 0.0001) layers. Conclusion: The inner choroidal layer significantly thinned with regression of MEWDS, correlating with the thinning of total choroidal thickness. These results suggest that MEWDS lesions in the choroid are likely to lie mainly in the inner layer.

    英語, 研究論文(学術雑誌), PURPOSE: To evaluate clinical features of Japanese patients with anti-α-enolase antibody-positive autoimmune retinopathy (anti-enolase AIR). DESIGN: Multicenter retrospective observational case series. METHODS: Forty-nine eyes of 25 Japanese anti-enolase AIR patients (16 female and 9 male; mean age at first visit, 60.8 years) were included. Fundus characteristics, perimetry, spectral-domain optical coherence tomography (SD-OCT), electroretinography (ERG), best-corrected visual acuity (BCVA), and complicating systemic tumors were assessed. Protein localization of α-enolase was examined by immunohistochemistry in an enucleated eye of 1 patient. RESULTS: Patients were classified into 3 groups: multiple drusen (48%), retinal degeneration (36%), and normal fundus (16%). Drusen varied in size from small deposits to vitelliform-like lesions. Images on SD-OCT revealed dome-shaped hyperreflectivity beneath the retinal pigment epithelium (RPE), corresponding to drusen. Perimetry showed that ring scotoma was the most frequent (39%). Rod-system and/or single-flash cone responses revealed decreased responses in 81% of the eyes. Combined rod and cone system responses demonstrated significantly lower a-wave amplitudes in the degeneration group than in the drusen group (P = .005). BCVA was improved or maintained in 80% of the eyes during follow-up. Malignant or benign tumors were detected in 30% of patients. The RPE and photoreceptor layers were immunopositive for α-enolase. CONCLUSIONS: The drusen subtype, scarcely described in the literature, is suggested to characterize Japanese patients with anti-enolase AIR. The different funduscopic features with different functional severities may have resulted from antibody-mediated damage to RPE as well as photoreceptor cells.

    英語, 研究論文(学術雑誌), Purpose: To evaluate the surgical outcomes of pars plana vitrectomy (PPV) with epipapillary membrane removal in patients with maculopathy associated with cavitary optic disc anomalies. Methods: Eight patients (8 eyes) with cavitary optic disc anomaly-associated maculopathy who underwent PPV with epipapillary membrane removal were retrospectively reviewed. The best-corrected visual acuity (BCVA) and macular and papillary morphologies using enhanced depth imaging optical coherence tomography (EDI-OCT) were evaluated before and after treatment. Immunohistochemistry for an intraoperatively excised epipapillary membrane tissue was also performed. Results: Before surgery, EDI-OCT revealed that epipapillary membrane was observed in all patients. Retinoschisis was resolved with no recurrence in all patients following vitrectomy regardless of a disease type or the presence or absence of preoperative posterior vitreous detachment. The mean final BCVA and central retinal thickness significantly improved compared with pretreatment values (P = 0.008 and 0.004, resp.). Immunoreactivity for S100 protein and glial fibrillary acidic protein, markers of astrocytes, was positive in the resected membrane tissues. Conclusions: These results suggest that epipapillary membrane is involved in the pathogenesis of some patients with cavitary optic disc anomaly-associated maculopathy as well as posterior hyaloid membrane. PPV with epipapillary membrane removal may be a useful treatment option for this maculopathy. This trial is registered with UMIN000011123.

    英語, 研究論文(学術雑誌), BACKGROUND: Muir-Torre syndrome (MTS) is a rare autosomal dominant genodermatosis caused by mutations in mismatch repair genes. It is characterized by the presence of at least one sebaceous skin tumor associated with internal malignancies. Whether positron emission tomography/computed tomography (PET/CT) is useful for the detection of malignancies in patients with MTS has not been determined. We herein report two cases in which PET/CT was useful for the diagnosis and follow-up of internal malignancies in patients with MTS. CASE PRESENTATION: In case 1, a 57-year-old woman underwent excision of a sebaceous carcinoma on the left upper eyelid. She underwent follow-up PET/CT once yearly thereafter. Forty-two months after the eyelid surgery, PET/CT showed intense tracer uptake in the right lower abdomen. An ascending colon tumor was identified, and examination of a biopsy specimen showed adenocarcinoma. In case 2, a 77-year-old man presented for evaluation of three continuous papules with telangiectasia on his right cheek. Examination of a skin biopsy specimen of the cheek papule revealed a sebaceous carcinoma. He underwent PET/CT to detect other malignancies. PET/CT showed intense tracer uptake in the sigmoid colon. A sigmoid colon tumor was identified, and examination of a biopsy specimen showed adenocarcinoma. Both patients underwent resection of their tumors, and both were still free of recurrence of the sebaceous and colon carcinomas at the time of this writing. CONCLUSION: PET/CT is a reliable imaging modality for the detection of internal malignancies and is useful for the diagnosis and follow-up of MTS.

    英語, 研究論文(学術雑誌), Glaucoma is characterized by axonal degeneration of retinal ganglion cells (RGCs) and apoptotic death of their cell bodies, and lowering intraocular pressure is associated with an attenuation of progressive optic nerve damage. Nevertheless, intraocular pressure (IOP) reduction alone was not enough to inhibit the progression of disease, which suggests the contribution of other factors to the glaucoma pathogenesis. In this study, we investigated the cytoprotective effect of geranylgeranylacetone (GGA) on RGCs degeneration using a normal tension glaucoma (NTG) mouse model, which lacks glutamate/aspartate transporter (GLAST) and demonstrates spontaneous RGC and optic nerve degeneration without elevated intraocular pressure (IOP). Three-week-old GLAST+/- mice were given oral administration of GGA at 100, 300, or 600 mg/kg/day or vehicle alone, and littermate control mice were given vehicle alone for 14 days, respectively. At 5 weeks after birth, the number of RGCs was counted in paraffin sections of retinal tissues stained with hematoxylin and eosin. In addition, retrograde labeling technique was also used to quantify the number of RGC. Expression and localization of heat shock protein 70 (HSP70) in retinas were evaluated by reverse transcription polymerase chain reaction and immunohistochemistry, respectively. Activities of caspase-9 and -3 in retinas were also assessed. The number of RGCs of GLAST+/- mice significantly decreased, as compared to that of control mice. RGC loss was significantly suppressed by administration of GGA at 600 mg/kg/day, compared with vehicle alone. Following GGA administration, HSP70 was significantly upregulated together with reduction in the activities of caspase-9 and -3. Our studies highlight HSP70 induction in the retina is available to suppress RGC degeneration, and thus GGA may be applicable for NTG as a promising therapy.

    英語, Measurements of interleukin (IL)-6 and -10 concentrations in the vitreous can be used to differentiate intraocular lymphoma (IOL) from uveitis. This is the first study reporting the IL-6 and -10 concentrations in the undiluted vitreous fluid and vitreous infusion fluid, which were simultaneously examined in the patients. A total of 2 females presented with intraocular inflammation, and underwent pars plana vitrectomy. Undiluted anterior vitreous and vitreous infusion fluid were collected simultaneously. IL concentrations were determined by enzyme-linked immunosorbent assay systems. Vitreous infusion fluid of 20 ml was eventually collected following completion of core vitrectomy in the two patients. IL-6 concentrations of the first patient were 513 and 106 pg/ml in the undiluted vitreous and the infusion fluid, respectively, while those of the second patient were 263 and 29 pg/ml. By contrast, IL-10 was under the detectable levels in all the fluids. The IL-10/-6 ratio was <1 in both fluids in the patients. Cytological examination revealed the presence of reactive inflammatory cells in the vitreous fluid. The two patients were eventually diagnosed with uveitis. Measurements of IL concentrations in the vitreous infusion fluid provided significant evidence on the differential diagnosis between IOL and uveitis, when considering how vitreous infusion fluid was diluted. The present study highlighted a novel application of cytokine analyses using the vitreous infusion fluid, which may contribute to the development of future translational researches on uveitis/IOL patients.

    英語, 研究論文(学術雑誌), For the purpose of investigating Behcet's disease (BD) in Russia, 250 consecutive patients (177 men and 73 women) diagnosed with BD between 1990 and 2010 at the Research Institute of Rheumatology, Russian Academy of Medical Sciences in Moscow were enrolled in this study. The ethnic backgrounds of the patients were reported as follows: 23.2% (58 cases) from Russia, 12.8% (32 cases) from Azerbaijan, 14.4% (36 cases) from Armenia, 8.8% (22 cases) from Chechnya, and 21.6% (55 cases) from Dagestan. The remaining 19.2% (48 cases) were from other regions or of unknown origin. More than half (57.6%) of the Behcet's disease patients originated from Central Asia, specifically Azerbaijan, Armenia, Chechnya, and Dagestan. The mean age at disease onset was 31.5 ± 9.38 (13-60) years old, and the most typical initial manifestations were oral aphthous ulcers. Patients aged 20-39 years old were more commonly affected and displayed a wide clinical spectrum of the disease, with varieties of severe internal organ involvement. The manifestations observed throughout the course of the disease included oral aphthous ulcers (100%), various cutaneous lesions (88.8%), genital ulcers (81.2%), and ocular lesions (54.0%). Besides these, many organs/systems were implicated in patient cases, namely joint (53.2%), vascular (25.2%), neurological (8.0%), gastrointestinal (25.2%), and cardiac (5.6%) systems. Involvements of ocular (p < 0.01) and skin (p < 0.01) lesions were more frequent in men than in women. HLA-B51 and HLA-A26 typing was performed in 127 patients and 508 healthy controls. HLA-B51 was found in 63.0% of BD patients compared to 20.7% of the healthy control subjects (p < 0.001), and HLA-A26 was present in 11.3% of BD patients and 18.9% of the control group. This study shows the presence of BD in Russia, and it is suggested that its prevalence in Central Asian people is much higher than that in White Russian.

    日本語, Human adenovirus (HAdV) causing epidemic keratoconjunctivitis is limited to D and E species. Recent progress in bioinformatics revealed that these viruses attach to the host with fibers, infiltrate the host cells via RGD (Arg-Gly-Asp) motif of penton base, and reveal their serological reaction by hexons. Loops 1 and 2 are the variable regions of each hexon. The possibility that a novel adenovirus later named HAdV-52 was transmitted over the wall of species' from monkeys to humans was reported. The recombination of the above three hot spots introduces novel types such as HAdV-53, -54, and -56. Boinformatics may provide rapid genotyping in nosocomial infection, predicting future epidemics, and an estimate of the therapeutic target molecules in the near future.

    英語, PURPOSE: Since some patients develop depigmentation of the trabecular meshwork in the course of Vogt-Koyanagi-Harada (VKH) disease, we examined the incidence of trabecular depigmentation and its correlation with other ocular findings and systemic symptoms. METHODS: We retrospectively reviewed the clinical charts of 53 Japanese patients diagnosed with VKH disease. The scores of trabecular and limbal pigmentation of all patients were recorded. We then examined the correlation between trabecular pigmentation and the presence of sunset glow fundus or skin lesions. RESULTS: Trabecular pigmentation was significantly lower in the patients with sunset glow fundus than in those without it (P = 0.022), whereas limbal pigmentation showed no significance. However, there were no significant differences in trabecular and limbal pigmentation between the patients with and those without skin lesions. Furthermore, there was no correlation between trabecular and limbal pigmentation. CONCLUSIONS: Depigmentation of the trabecular meshwork develops in some patients in the course of VKH disease. This depigmentation is significantly correlated with sunset glow fundus, but not with limbal depigmentation or skin lesions.

    英語, Acute ultraviolet (UV) B exposure causes photokeratitis and induces apoptosis in corneal cells. Geranylgeranylacetone (GGA) is an acyclic polyisoprenoid that induces expression of heat shock protein (HSP)70, a soluble intracellular chaperone protein expressed in various tissues, protecting cells against stress conditions. We examined whether induction of HSP70 has therapeutic effects on UV-photokeratitis in mice. C57 BL/6 mice were divided into four groups, GGA-treated (500 mg/kg/mouse) and UVB-exposed (400 mJ/cm2), GGA-untreated UVB-exposed (400 mJ/cm2), GGA-treated (500 mg/kg/mouse) but not exposed and naive controls. Eyeballs were collected 24 h after irradiation, and corneas were stained with hematoxylin and eosin (H&E) and terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL). HSP70, reactive oxygen species (ROS) production, nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) and protein kinase B (Akt) expression were also evaluated. Irradiated corneal epithelium was significantly thicker in the eyes of mice treated with GGA compared with those given the vehicle alone (p < 0.01). Significantly fewer TUNEL-positive cells were observed in the eyes of GGA-treated mice than controls after irradiation (p < 0.01). Corneal HSP70 levels were significantly elevated in corneas of mice treated with GGA (p < 0.05). ROS signal was not affected by GGA. NF-κB activation was reduced but phospho-(Ser/Ther) Akt substrate expression was increased in corneas after irradiation when treated with GGA. GGA-treatment induced HSP70 expression and ameliorated UV-induced corneal damage through the reduced NF-κB activation and possibly increased Akt phosphorilation.

    英語, BACKGROUND: Chickenpox is rarely associated with posterior segment inflammation. We report on a case of unilateral chickenpox chorioretinitis with retinal exudates and periphlebitis. CASE PRESENTATION: A 21-year-old healthy man, who suffered from chickenpox 2 weeks prior to symptom development, exhibited mild anterior chamber cells, vitreous opacity, sheathing of retinal veins, and yellow-white exudates in his right eye. Varicella zoster virus DNA was detected by polymerase chain reaction in the aqueous humor. He was treated with intravenous acyclovir followed by oral prednisolone and valaciclovir. Aqueous cells quickly disappeared and retinal exudates diminished within 1 month, leaving faint retinal scarring. Retinal arteritis had never been observed in this patient. CONCLUSIONS: ALTHOUGH THE OCULAR FINDINGS IN THIS CASE WERE SIMILAR TO ACUTE RETINAL NECROSIS (ARN), THE CLINICAL FEATURES DIFFERED FROM ARN IN THE FOLLOWING POINTS: (1) mild anterior chamber inflammation, (2) absence of retinal arteritis, and (3) prompt resolution of inflammatory findings. The distinctive clinical features indicated that chorioretinitis associated with chickenpox may not have the same pathological conditions as ARN.

    英語, PURPOSE: To investigate the expression, localization, and physiologic function of renin-angiotensin system (RAS) components in the mouse lacrimal gland. METHODS: Lacrimal glands and cultured lacrimal gland fibroblasts from wild-type (WT) BALB/c (H-2(d)) mice were used. Reverse transcription-polymerase chain reaction (RT-PCR) and immunohistochemistry were used to determine the expression and localization of the RAS components, prorenin/renin, angiotensin-converting enzyme (ACE), angiotensin II, angiotensin II type 1 receptor (AT1R), and angiotensin II type 2 receptor (AT2R) in the normal mouse lacrimal gland. To examine the change in tear secretion, mice received ARB (AT1R blocker) or AT2R antagonist. Tear secretion was assessed by cotton thread test before and after drug administration. RESULTS: The mRNAs coding for angiotensinogen, prorenin, ACE, and both AT1R and AT2R were found in normal lacrimal gland tissue and cultured lacrimal gland fibroblasts. Prorenin/renin and ACE were identified in myoepithelial cells around ducts and acini and in blood vessels. Angiotensin II, AT1R, and AT2R were observed in the ducts and interstitial fibroblasts. AT1R and AT2R were also localized in b

    英語, PURPOSE: To investigate the role of reactive oxygen species (ROS) as the prime initiators of the angiogenic response after alkali injury of the cornea and observe the effects of antioxidants in preventing angiogenesis. METHODS: The corneal epithelia of SOD-1-deficient mice or wild-type (WT) mice were removed after application of 0.15 N NaOH to establish the animal model of alkali burn. ROS production was semiquantitatively measured by dihydroethidium (DHE) fluorescence. Angiogenesis was visualized by CD31 immunohistochemistry. The effects of the specific NF-kappaB inhibitor DHMEQ, the antioxidant N-acetyl-L-cysteine (NAC), and hydrogen (H2) solution were observed. RESULTS: ROS production in the cornea was enhanced immediately after alkali injury, as shown by increased DHE fluorescence (P<0.01). NF-kappaB activation and the upregulation of vascular endothelial growth factor (VEGF) and monocyte chemoattractant protein-1 (MCP-1) were significantly enhanced (P<0.01), leading to a significantly larger area of angiogenesis. Angiogenesis in SOD-1-/- mice corneas were significantly higher in WT mice (P<0.01), confirming the role of ROS. Pretreatment with the specific NF-kappaB inhibitor DH

    PURPOSE: CD44 is a cell-surface adhesion molecule and receptor for hyaluronan (HA), one of the major extracellular matrix components. The purpose of the present study was to clarify a role of HA and CD44 in the development of choroidal neovascularization (CNV). METHODS: Laser photocoagulation was used to induce CNV in C57BL/6 mice or CD44-deficient mice. The mRNA expression of CD44 and HA synthase (HAS)-2 in the retinal pigment epithelium (RPE)-choroid complex was evaluated by DNA microarray and real-time RT-PCR analyses 3 days after laser treatment. HA synthesis and CD44 expression were examined by immunohistochemistry 1 week after photocoagulation. Mice with laser-induced CNV were systemically administered the HA synthesis inhibitor 4-methylumbelliferone (MU) or an anti-CD44-neutralizing antibody. The response of CNV was analyzed by volumetric measurements 1 week after photocoagulation. Macrophage infiltration into CNV lesions was evaluated by real-time RT-PCR for F4/80 3 days after laser-induced injury. RESULTS: The induction of CNV led to a significant increase in expression of CD44 and HAS2 mRNA. HA and CD44 were immunopositive in the CNV lesions. Compared with vehicle treatme

    英語, 研究論文(学術雑誌), <p>PURPOSE. Angiotensin II type 1 receptor (AT1-R) blockers are used widely for the treatment of patients with hypertension. Recent reports have suggested that AT1-R also plays a key role in various inflammatory conditions. The aim of this study was to examine whether blockade of AT1-R is effective in the suppression of murine experimental autoimmune uveoretinitis (EAU). METHODS. C57BL/6 mice were immunized with human interphotoreceptor retinoid binding protein-derived peptide 1-20 (hIRBP-p). Telmisartan, an AT1-R blocker, was administrated daily by intraperitoneal injection. On day 21 after immunization, the severity of EAU was assessed clinically and histopathologically. With the use of flow cytometry, the activation of draining lymph node (LN) cells was assessed by cell proliferation response against hIRBP-p and by the number of CD44<sup>high</sup> activated CD4<sup>+</sup> T cells present. In addition, mRNA expression of ICAM-1, MCP-1, and IFN-γ in the eye was analyzed by reverse-transcriptase PCR, and the number of retinal adherent leukocytes was counted by retinal perfusion labeling. RESULTS. Telmisartan significantly suppressed EAU clinically and histopathologically. Intrao

    英語, BACKGROUND: The development of rhegmatogenous retinal detachments (RRDs) in eyes with a history of congenital glaucoma (CG) is very rare. We present the characteristics and surgical outcomes of three cases with a RRD who had CG and had undergone surgery many years earlier. CASES: Three men, ages 14, 43, and 48 years of age, each with a history of surgery for primary CG, presented with a RRD. All of the eyes were highly myopic. The retinal tears were located at the equator in all cases. The degree of RRD were superior half, total, and total (proliferative vitreoretinopathy). OBSERVATIONS: Vitrectomy was performed and the retinas were reattached in all cases. However, the visual acuity in all cases remained poor. CONCLUSIONS: Our findings indicate that a posterior vitreous detachment due to advanced vitreous liquefaction in the highly myopic eyes may have been the cause of the RRD. We recommend periodic fundus examinations in patients with CG, because while the RRD in patients with CG can be reattached the functional recovery may not be good.

    英語, PURPOSE: To investigate whether the induction of cytotoxic T lymphocytes (CTLs) targeting VEGF receptor 2 inhibits corneal neovascularization caused by alkali injury. METHODS: H-2Db-restricted peptide corresponding to amino acids 400 to 408 of VEGF receptor 2 (VEGFR2(400-408)) was used as an epitope peptide. Dendritic cells (DCs) were harvested from bone marrow progenitors of C57BL/6 mice. Six-week-old C57BL/6 mice received subcutaneous injections of VEGFR2(400-408)- or gp70-pulsed mature DCs three times at 6-day intervals. After the third immunization, corneal neovascularization was induced by alkali injury. Two weeks after the injury, the corneal vascularized area was evaluated by lectin angiography. To confirm the peptide-specific CTL activities in C57BL/6 mice, CD8(+) T cells from immunized mice were subjected to ELISA for interferon (IFN)-gamma and tumor necrosis factor (TNF)-alpha production and (51)Cr-release cytotoxicity assay. To determine the in vivo effector T cells, the immunized mice were intraperitoneally injected with an anti-CD4 or -CD8 depletion antibody. RESULTS: Corneal neovascularization was significantly attenuated in mice immunized with VEGFR2(400-408) compare

    英語, PURPOSE: To determine whether vitrectomy with 25-gauge instruments contributes to better postoperative visual recovery after macular hole (MH) surgery. METHODS: The medical records for 46 consecutive eyes operated for MH by a single surgeon were retrospectively examined. Vitrectomy had been performed with a 25-gauge instrument in 23 eyes (25-G group) and with a 20-gauge instrument in 23 eyes (20-G group). Postoperative visual acuity (VA) in logMAR (logarithm of the minimum angle of resolution) units after 1 week and 1, 3, 6, 9 and 12 months, operating time, and volume of intraocular irrigating fluid were compared between the two groups. RESULTS: Mean preoperative logMAR VA was 0.72 in the 25-G group and 0.68 in the 20-G group (p = 0.282, unpaired t-test). One week after surgery, VA was significantly better in the 25-G group (0.40 +/- 0.34) than in the 20-G group (0.58 +/- 0.30) (p = 0.020). This significant difference was maintained until 9 months after surgery, but was no longer evident at 12 months (p = 0.182). Operating time was significantly shorter in the 25-G group (56 +/- 16 mins) than in the 20-G group (85 +/- 28 mins) (p = 0.003, unpaired t-test). The volume of intraocular

    日本語, 滲出型加齢黄斑変性の中心的病態は,脈絡膜血管新生であり,新生血管の透過性亢進による滲出性変化が神経網膜を恒久的に傷害する.近年の細胞生物学の進歩は,これらの病態における複数の分子メカニズムを明らかにしてきたため,特定の分子を標的とした阻害薬が開発される時代になった.なかでも血管内皮増殖因子(VEGF)は,進行の鍵となる2つの病態,血管新生・血管透過性亢進を促進することが明らかにされ,その阻害薬の臨床応用が実現した.眼科領域で臨床応用されたVEGF阻害薬pegaptanib(Macugen®),ranibizumab(Lucentis®),bevacizumab(Avastin®)は,黄斑浮腫・剥離や血管新生を軽減させ,少なくとも短期的には有効であることがわかった.しかし,至適な投与法,長期の安全性,既存の光線力学療法との併用についてなど,検討すべき課題が山積みされている.

    英語, 研究論文(学術雑誌), <p>Recent reports indicated that tissue renin-angiotensin system (RAS) was upregulated and angiotensin II type 1 receptor signaling plays cmcial roles in ocular inflammation and neovascularization; however, the precise mechanism for activating tissue RAS had not been defined until recently. (Pro)renin receptor, a recently identified molecule existing in the major organs but not in the circulation, has attracted growing attention as an activator of tissue RAS. When the handle region of the prorenin prosegment binds to (pro)renin receptor, prorenin undergoes a conformational change to its enzymatically active state without the conventional proteolysis of the prorenin prosegment. Systemic treatment with a peptide with the structure of the handle region (handle region peptide; HRP), which competitively binds to (pro)renin receptor as a decoy peptide and inhibit the nonproteolytic activation of prorenin, resulted in the suppression of retinal inflammation and neovascularizaion in the rodent models. Retinal expression of RAS-related inflammatory and angiogenic molecules, such as intercellular adhesion molecule-1, monocyte chemotactic protein-1, and vascular endothelial growth factor, was

    英語, 研究論文(学術雑誌), PURPOSE:



    To compare the surgical outcomes and complications of vitrectomy with internal limiting membrane (ILM) peeling with or without indocyanine green (ICG) staining in eyes with an idiopathic macular hole.



    METHODS:



    This study involved a non-randomized, single-centre, retrospective, interventional case series. Rates of anatomical closure, visual acuities (VAs) and postoperative complications in 35 eyes of 31 patients who underwent ICG-assisted ILM peeling during macular hole surgery (stained group) were compared with those in 18 eyes of 16 patients who underwent the same procedure without ICG staining (non-stained group).



    RESULTS:



    Macular holes were closed following the initial surgery in 97% of the stained group and 94% of the non-stained group (p > 0.999). There was no significant difference in mean final VA between the stained and non-stained groups, but there was a lower percentage of eyes with postoperative vision > 20/25 in the stained group (15%) than in the non-stained group (44%) after 2 years (p = 0.036). Posterior retinal pigment epithelium atrophy, retinoschisis and visual field defects were observed only in the stained group.



    CONCLUSIONS:

    英語, PURPOSE: To investigate the visual sensations experienced by patients during vitrectomy under retrobulbar anesthesia. DESIGN: Cross-sectional study. METHODS: Fifty-six men and 45 women with a mean age of 62.2 +/- 11.9 years (range, 30 to 89 years) were studied. Twenty-two eyes had an idiopathic epiretinal membrane, 10 had an idiopathic macular hole, 29 had macular edema (16 resulting from diabetic retinopathy and 13 resulting from retinal vein occlusion), 14 had proliferative diabetic retinopathy, 13 had rhegmatogenous retinal detachment, four had proliferative vitreoretinopathy, and nine had other retinal diseases. The patients were questioned about their visual sensations during and within three hours after vitrectomy, which was performed under retrobulbar anesthesia using 2% lidocaine hydrochloride. Visual sensations perceived by the patients during surgery were reviewed. RESULTS: Ninety-one of the 101 patients experienced some type of visual sensation during the vitrectomy. Ninety-one (90.1%) patients reported seeing lights, 73 (72.3%) patients reported seeing one or more colors, and 57 (56.4%) patients reported seeing movements or moving objects. Of these latter 57 patients, 5

  • Current concept of the pathogenesis of age-related macular degeneration : the role of oxidative stress and inflammation

    炎症・再生 : 日本炎症・再生医学会雑誌 = Inflammation and regeneration, 26, 6, 492, 500, 日本炎症・再生医学会, 2006年11月25日
    英語, Age-related macular degeneration (AMD) is a common disorder in the aged people that affects the central region of the retina, which is called macula. AMD is the leading cause of legal blindness in people older than 65 in the developed world. AMD is characterized by very typical retinal pathologies including drusen, retinal pigment epithelium dysfunction, retinal degeneration (geographic atrophy) and choroidal neovascu-larization. Recent studies reveal that oxidative stress and inflammation are significantly linked to the pathogenesis of AMD. Retina is especially susceptible to oxidative stress by following reasons: 1) photoreceptors contain polyunsaturated fatty acids, 2) retina is exposed continuously to light, 3) its oxygen consumption is high, 4) it contains chromopheres which react with light and produce reactive oxygen species (ROS). Moreover, ran-domized, prospective, placebo-controlled study in United States showed that high-dose supplementation of beta-caroten, vitamin C, vitamin E, copper, and zinc significantly slowed the progression of the disease and visual deterioration in patients with AMD. Mice deficient of Cu, Zn-superoxide dismutase showed typical features of human AMD, suggesting that oxidative stress scavenger may play a critical role in the prevention of age-related retinal degeneration. Obesity and inflammatory biomarkers are significantly associated with the risk of AMD, which possibly indicates that AMD is considered as a consequence of disturbance of homeo-stasis, such as metabolic syndrome. Recent genetic studies showed genes related to immune system via complement are associated with AMD, which revealed that inflammatory reactions are causally linked with the pathogenesis of AMD. Recently, the inhibitor of angiotensin II type 1 receptor reduced the volume of experimental CNV after laser burn, suggesting that angiotensin II type 1 receptor blockade be a novel therapeutic strategy as a preventive treatment for AMD. Further research is necessary to invent mechanism-based therapies forAMD.

  • Glycer-AGEによる網膜神経病態の機序解明と糖尿病網膜症に対する創薬

    糖尿病網膜症は重篤な視機能障害をきたす疾患であり、その病態理解は眼科学における重要課題である。これまでの糖尿病網膜症治療はその血管病態を制御することを目的とされてきたが、近年、糖尿病網膜症における「神経病態」が注目されている。しかし、糖尿病網膜症における神経保護的治療法は現在のところ確立されていない。
    グリセルアルデヒド由来の終末糖化産物(Glycer-AGE)は、その細胞障害性の強さからToxic AGE(TAGE)とも呼ばれ、糖尿病網膜症を含む様々な疾患での病態形成への関与が報告されている。申請者グループの検討により、このTAGEが糖尿病モデルマウスの視細胞変性に寄与していることが明らかになった。本研究では、TAGEによる網膜神経病態の機序を解明し、さらにTAGEを標的とした創薬開発を行い、糖尿病網膜症の新規治療法開発を目指す。
    本研究におけるこれまでの検討により、ヒト培養網膜色素上皮細胞にグリセルアルデヒドを添加してTAGE化反応を誘導し、抗TAGEモノクローナル抗体で免疫沈降をおこなって質量分析に供し、グリセルアルデヒドを添加しないコントロール群と比較することで、網膜色素上皮細胞内でTAGE化される複数のタンパク質を同定している。また、ヒト培養網膜色素上皮細胞にグリセルアルデヒドと牛血清アルブミン(BSA)を反応させて作製したTAGE化BSAを添加し、TAGE負荷が網膜色素上皮細胞機能に及ぼす影響について現在解析を進めている。

  • VIPR2による中心性漿液性脈絡網膜症における分子病態の解明

    Vasoactive intestinal peptide (VIP)およびvasoactive intestinal peptide receptor (VIPR)2の中枢および血管に対する作用は、中心性漿液性脈絡網膜症(CSC)患者の病態と考えられている精神的ストレスと脈絡膜血管局所的収縮の両者と反対の特徴を持つ。これまで、VIPR2-KOマウスを用いたCSCの研究は無く、CSCの神経生理学的・細胞生物学的な病態は証明することができなかった。 本研究では、VIPR2-KOマウスにストレス負荷を与えた実験系において、中枢神経系および脈絡膜局所の両面における神経生理学的・細胞生物学的探索、および脈絡膜の形態・血流変化を観察することによって、VIPR2-KOマウスがCSCのモデル動物となりうるかを検証し、その病態を分子メカニズムから解明する。
    現在、CSCモデル動物を構築するために、VIPR2-KOマウスの樹立について準備を進めているところである。同時に、恐怖刺激などの刺激を行うために必要な機材、器具等の準備、予備検討などを進めている段階である。また、ヒトのCSC患者についても安静時機能的 MRIおよびミネソタ多面人格目録などの質問票による性格検査などを行うためデータをとる必要がある。コロナウイルスの影響などによりやや遅れが生じているものの、網膜および黄斑などの専門外来において患者の適格性を検討し、今後の状況などを見極めつつ選定を進めていこうと考えている。

    我が国における最大の失明原因は緑内障である。特に我が国で患者数が多い正常眼圧緑内障(NTG)については、眼圧降下療法以外の治療法が求められている。本研究では点眼薬だけでなく、酸化ストレスを抑制する既存薬や食品に含まれる成分、さらにカロリー制限による神経保護効果を報告した。また、よりヒトに近いモデルとして霊長類であるマーモセットを検討する中で、一定数の老齢個体がNTGを自然発症することを見出した。すでに遺伝子探索、血液及び脳脊髄液検査、MRIによる検討を終え、緑内障患者の特徴がいくつも再現されていることを確認済みである。さらに現在は遺伝子改変によるNTGマーモセットを作成中である。

  • ATMの網膜・脈絡膜血管病態への関与
    科学研究費助成事業
    2006年 - 2007年
    井上 真, 石田 晋
    ATMは毛細血管拡張性運動失調症(ataxia telangiectasia)の原因還伝子であるAtm(ataxia telangi ectasia mutated)の遺伝子産物であり、DNA複製・修復に関与するプロテインキナーゼの一つである。Atm遺伝子は1995年にクローニングされ、ヒトでは全長約150 kbで66個のエクソンからなる巨大な遺伝子である。ATMは細胞周期チェックポイント機能を有し、DNA障害をうけた細胞の細胞周期を停止させDNA修復のための時間をつくる。また毛細血管拡張性運動失調症患者では高頻度にリンパ系腫瘍などの悪性腫瘍の発症を認め、腫瘍細胞にAtm遺伝子の変異や欠損が見いだされている。Atm遺伝子変異を有する腫瘍細胞ではDNA修復機能が傷害されており、ATMの機能消失が発ガンと関連することが示唆されている。最近、ATMは造血幹細胞において酸化ストレスを抑制することで幹細胞の自己複製能の維持に寄与することがAtmノックアウトマウスを用いた解析で明らかになった(Ito K, et.al.Nature 2004,997-1002)。そこでATMを適正に制御することにより酸化ストレスなどの糖尿病網膜症の背景となる病態を制御できる可能性が示唆される。我々はConcanavalin A(Con A)レクチンによる灌流ラベル法を用いてC57BL/6正常マウスと比較してAtm+/-マウス及びAtm-/-マウスにおいて網膜血管白血球接着が亢進している事を明らかにした。またSTZ糖尿病モデルを作成し、同様に灌流ラベル法を用いて網膜血管白血球接着を調べるとAtm+/-マウス及びAtm-/-マウスにおいては糖尿病モデル作成前後で変化は認められなかった。STZ糖尿病では網膜血管における酸化ストレスが充進している事が知られており、このメカニズムがATMを介している可能性が示唆された。

    糖尿病網膜症における血液網膜関門機能の破綻機序について、誘因として組織低酸素状態に注目するとともに、中枢神経系の血管内皮細胞間tight junctionを構成する分子であるclaudin-5の関与に焦点をあて解析を進めた。正常酸素濃度環境下のin vitro bEND.3細胞(マウス脳血管内皮細胞株)およびin vivoマウス網膜血管内皮細胞において細胞膜に限局した発現を示すclaudin-5が、低酸素濃度環境下〔1%O_2下24時間培養(in vitro);7-9%O_2下7日間飼育(in vivo)〕では細胞膜から消失するという興味深い知見を得た。そして、その低酸素状態でのclaudin-5発現変化が、in vitro系においてはbEND.3細胞層の電気抵抗値、in vivo系においては網膜血管の低分子量分子に対する透過性亢進と相関することが示され、低酸素状態がclaudin-5を標的として血液網膜関門機能を破綻させることが強く示唆された。続いて、この低酸素状態でのclaudin-5発現変化の分子機構の詳細につきin vitro系にて解析を行った。その結果、正常酸素濃度環境下に比して低酸素濃度環境下のbEND.3細胞ではclaudin-5蛋白質レベルが有意に低下するのに対し、claudin-5 mRNAレベルには有意な変化がみられないことが示された。さらに、種々の細胞内蛋白質の分解に関与するユビキチン-プロテアソーム系の阻害剤であるMG-132を用い解析を行ったところ、低酸素状態でのbEND.3細胞膜からのclaudin-5分子の消失が、MG-132の存在下では抑制され、低酸素状態におけるclaudin-5の発現変化にユビキチン-プロテアソーム系が関与する可能性が示唆された。

    糖尿病網膜症の病態を、病的血管新生病変(線維血管性組織)形成、血液網膜関門の破綻による網膜浮腫形成の両側面から解析を行った。これまで我々は、線維血管性組織形成には網膜グリア細胞におけるVEGF_<165>とMT1-MMPの産生誘導が重要であることを見出したが、本研究期間には、これら責任因子の発現誘導における組織低酸素状態の誘因としての重要性を検討した。まず家兎を用い網膜グリア細胞の単離・培養系を確立し低酸素濃度下にて培養したところ、VEGF_<165>とMT1-MMPの産生誘導が確認された。さらに、網膜グリア細胞が低酸素濃度下において高親和性VEGF受容体の一つVEGFR-2を発現すること、VEGFR-2特異的阻害剤SU1498あるいは抗VEGF中和抗体の存在下では低酸素刺激においてもMT1-MMP産生が誘導されないことを見出した。即ち、組織低酸素状態により網膜グリア細胞にVEGF_<165>産生が誘導されるとともに、そのVEGF_<165>が間接的にMT1-MMPを誘導することが示された。一方、血液網膜関門破綻についてはclaudin-5に注目した解析を行った。まず、マウス網膜伸展標本を作製しclaudin-5の発現を検索したところ、網膜血管内皮細胞間の細胞膜上にclaudin-5の発現・局在が証明され、脳血管同様に網膜血管の関門機能におけるclaudin-5の重要性が示唆された。そこで、マウス血管内皮細胞bEND.3を用い、低酸素濃度下におけるclaudin-5の動態を解析した。bEND.3を単層培養するとconfluent状態でclaudin-5は細胞膜へ局在するが、低酸素刺激を加えると細胞膜からcludin-5が消失することにより関門機能が低下した。さらに、この低酸素濃度下におけるclaudin-5の発現変化へのMAP kinase系の関与を示唆する知見を得ているが、現在さらなる解析を行っている。以上、組織低酸素状態が病態責任因子の発現変化を介し、線維血管性組織形成・網膜浮腫形成の誘因として働いていることが示唆された。
