Our previous studies demonstrated that periostin (PN) and tenascin-C (TNC) are involved in the pathogenesis of IPR. However, the interactive role of PN and TNC in angiogenesis associated with IPR remain unknown. We found significant correlation between concentrations of PN and TNC in PDR vitreous humor. mRNA and protein expression of PN and TNC were found in pre-retinal fibrovascular membranes excised from PDR patients. Interleukin-13 (IL-13) promoted mRNA and protein expression of PN and TNC, and co-immunoprecipitation assay revealed binding between PN and TNC in human microvascular endothelial cells (HRECs). IL-13 promoted angiogenic functions of HRECs. Single inhibition of PN or TNC and their dual inhibition by siRNA suppressed the up-regulated angiogenic functions. Pathological pre-retinal neovessels of oxygen-induced retinopathy (OIR) mice were attenuated in PN knock-out, TNC knock-out and dual knock-out mice compared to wild-type mice. Both in vitro and in vivo, PN inhibition had a stronger inhibitory effect on angiogenesis compared to TNC inhibition, and had a similar effect to dual inhibition of PN and TNC. Furthermore, PN knock-out mice showed scant TNC expression in pre-retinal neovessels of OIR retinas. Our findings suggest that interaction of PN and TNC facilitates pre-retinal angiogenesis, and PN is an effective therapeutic target for IPR such as PDR..|

Study design: Retrospective case series. Methods: Nine patients from 5 unrelated Japanese families were studied. Five patients had the m1 variant homozygously, and 4 patients had the m1 variant compound heterozygously with another frameshift variant (c.4196delG/p.Cys1399Leufs*5). Ophthalmic examinations including adaptive optics (AO) fundus imaging were performed periodically. Results: The fundus photographs, fundus autofluorescence (FAF) images, and optical coherence tomographic (OCT) images indicated severe retinal degeneration in all the patients involving the macula even at a young age (20 s). The areas of surviving photoreceptors in the central macula were seen as hyper-autofluorescent regions in the FAF images and preserved outer retinal structure in the OCT images; they were identifiable in the AO fundus images in 8 eyes. The borders of the surviving photoreceptor areas were surrounded by hyporeflective clumps, presumably containing melanin, and the size of these areas decreased progressively during the 4-year follow-up period. The disappearance of the surviving photoreceptor areas was associated with complete blindness. Conclusion: Patients with RP associated with the m1 variant have a progressive and severe retinal degeneration that begins at an early age. Monitoring the surviving photoreceptor areas by AO fundus imaging can provide a more precise pathological record of retinal degeneration..|

a phase III physician-initiated multicenter clinical trial, Japanese Journal of Ophthalmology, 10.1007/s10384-020-00763-y, 64, 5, 455-461, 2020.09, Purpose: To evaluate the safety and efficacy of BBG (Brilliant Blue G250) for lens capsular staining during cataract surgery with continuous curvilinear capsulorhexis. Study design: Prospective clinical study. Methods: This clinical trial enrolled 30 eyes of 30 patients who underwent cataract surgery with BBG (0.25 mg/mL Brilliant Blue G250) for capsular staining. Visualization of the lens capsule and the ease of capsulorhexis with BBG staining were evaluated in five grades (grade 0 to 4) by the Independent Data Monitoring Committee and the surgeons. The safety of BBG was also evaluated in terms of ocular and systemic tolerance for 7 days after surgery. Results: The use of BBG improved visualization of the lens capsule and complete capsulorhexis was performed in all patients. The major endpoint (Independent Data Monitoring Committee evaluation) showed that use of BBG improved visualization of the lens capsule and the ease of capsulorhexis (grades 2 to 4); the committee’s grading results were similar to those of the surgeons. Frequent complications observed in more than two eyes were conjunctival injection, corneal edema and intraocular pressure elevation. No severe complications were observed in ocular and systemic evaluations. Conclusion: BBG staining contributed to improved visualization of the lens capsule and aided in the completion of capsulorhexis during cataract surgery. The use of BBG for capsular staining also exhibited favorable safety results..

To investigate the association between aqueous flare and progression of visual field loss using the Humphrey Field Analyzer in patients with retinitis pigmentosa (RP). METHODS. We examined a total of 101 eyes of 101 patients who were diagnosed with typical RP. Sixty-one percent of the patients were female, and the mean age of the total group was 47.4 years. Aqueous flare, visual field (by an Humphrey Field Analyzer, the central 10-2 SITA-Standard program), and optical coherence tomography measurements were obtained for all patients. The slope, which was derived from serial values of mean deviation, macular sensitivity, or foveal sensitivity for each eye with univariate linear regression, was used for analysis. RESULTS. Aqueous flare values were significantly correlated with the mean deviation slope (r =-0.20, P = 0.046), macular sensitivity slope (r =-0.28, P = 0.005) and foveal sensitivity slope (r =-0.20, P = 0.047). The values of the retinal sensitivity slope significantly decreased as the aqueous flare level increased (all P < 0.05). These associations remained unchanged after adjustment for age, sex, and posterior subcapsular cataract, and epiretinal membrane. CONCLUSIONS. Elevation of aqueous flare is a risk factor for the decline of central visual function in RP. Aqueous flare may be a useful marker for disease progression in RP..|

However, in the first decade of this century, advances in biomedicine have provided new treatment strategies in the field of ophthalmology, particularly biologics that target vascular endothelial growth factor or tumor necrosis factor (TNF)-α. Furthermore, clinical trials on gene therapy specifically for patients with autosomal recessive or X-linked RP have commenced. The overall survival rates of patients with VRL have improved, owing to earlier diagnoses and better treatment strategies. However, some unresolved problems remain such as primary or secondary non-response to biologics or chemotherapy, and the lack of adequate strategies for treating most RP patients. In this review, we provide an overview of the immunological mechanisms of the eye under normal conditions and in several retinal disorders, including uveitis, DR, ROP, RP, and VRL. In addition, we discuss recent studies that describe the inflammatory responses that occur during the course of these retinal disorders to provide new insights into their diagnosis and treatment..|

This article aimed to describe the cases of two patients with macular retinoschisis who underwent vitrectomy with peripapillary internal limiting membrane peeling around the defective area of the retinal nerve fiber layer. Observations: Both patients had been diagnosed with normal tension glaucoma and treated with eye drops to stabilize intraocular pressure. Progression of macular retinoschisis and accompanied vision loss were observed in both cases. Twelve months after the surgery, both patients had resolution of the retinoschisis and improvement in best corrected visual acuity. Conclusions and importance: Our surgical technique may be effective for the resolution of macular retinoschisis in eyes with normal tension glaucoma..|

For the maintenance of retinal homeostasis, these cells and immunosuppressive molecules in the eye actively regulate the induction and the expression of inflammation in order to prevent excessive activation and subsequent tissue damage. In the disease context, these regulatory mechanisms are modulated genetically and/or by environmental stimuli such as damage-associated molecular patterns (DAMPs), and a chronic innate immune response regulates or contributes to the formation of diverse retinal disorders such as uveitis, retinitis pigmentosa, retinal vascular diseases and retinal fibrosis. Here we summarize the recent knowledge regarding the innate immune response in both ocular immune regulation and inflammatory retinal diseases, and we describe the potential of the innate immune response as a biomarker and therapeutic target..|

preoperative findings in eyes with primary retinal detachment, Japanese Journal of Ophthalmology, 10.1007/s10384-019-00702-6, 64, 1, 2020.01, Purpose: To report the demographics and clinical characteristics of patients with a primary retinal detachment (RD). Design: Prospective cohort study by a registry design. Participants: Patients with RD treated at vitreoretinal sub-specialty institutions in Japan from February 2016 to March 2017. Methods: Descriptive statistics for the primary RD, and multivariable ordered logistic regression and multiple linear regression analyses were performed. Results: 3178 eyes of 3178 cases were analyzed. The interval from onset to surgery was significantly shorter in patients in the 40-year age group than in other age groups except for the 50-year age group (P<0.05, Steel-Dwass test). The proportion of complex cases was significantly higher in the 10-year, 70-year, and 80+ year age groups than in the 40 and 50-year age groups (P<0.05, Steel-Dwass test). The size of RD was significantly associated with the male sex (odds ratio, 1.29; 95% confidence interval [CI], 1.07 to 1.56; P=0.0085) and the interval from onset to surgery (odds ratio, 1.03 95% CI, 1.01 to 1.04; P=0.0014). Low IOPs in eyes with RD were significantly associated with an older age (-0.24 mmHg/10 years, 95% CI, -0.32 to -0.16], P<0.0001) and larger RD area (-0.91 mmHg/quadrant, 95% CI, [-1.06 to -0.76], P <0.0001). Conclusion: Profile and clinical characteristics of patients with a primary RD were not exactly the same as previous reports. A preoperative low IOP was associated with several ocular factors while the area of RD was associated not only with ocular but with social factors as well..

OCTA signals would be more utilized if they are associated with blood flow dynamics of each layer. In this study, morphological top-hat transform was applied for OCTA en face retinal images of superficial and deep layers obtained from patients of diabetic retinopathy and controls to quantify the caliber-specific flow path length. As a result, the total length of the thick flow paths in deep layer more strongly reflected the progress of retinopathy than that in superficial layer. Supposing the thick flow paths observed in deep layer OCTA as a superposition of multiple capillaries, this trend seemed to be a possible expression of partial clogs of the capillary network..|

The Hisayama Study, JAMA Ophthalmology, 10.1001/jamaophthalmol.2020.2211, 2020, Importance: Myopic maculopathy is a leading cause of irreversible visual impairment worldwide. Moreover, the burden of myopic maculopathy has been expected to increase owing to the rising prevalence of myopia globally. However, there is limited epidemiologic evidence regarding the incidence of and risk factors for myopic maculopathy. This study from Japan, with a relatively high prevalence of myopia, could provide valuable information related to these issues. Objective: To estimate the incidence of myopic maculopathy and its risk factors in Hisayama in southwestern Japan. Design, Setting, and Participants: A population-based prospective cohort study in a Japanese community in Hisayama, Japan. The study included a total of 2164 residents 40 years or older who had no myopic maculopathy at the baseline eye examination in 2012 and underwent follow-up eye examinations in 2017. Main Outcomes and Measures: Incidence of myopic maculopathy. The grades of myopic maculopathy were categorized based on the criteria of the Meta-analysis of Pathologic Myopia Study Group classification system. Results: The mean (SD) age of the study participants was 62.4 (10.9) years, and the proportion of men was 42.5% (920 participants). In the follow-up examination in 2017, 24 patients developed myopic maculopathy. The 5-year cumulative incidence of myopic maculopathy was 1.1% (95% CI, 0.6-1.5) overall, 1.4% (95% CI, 0.6-2.2) for men, and 0.9% (95% CI, 0.4-1.4) for women. Multiple logistic regression analysis showed that older age (per 1 year; odds ratio [OR], 1.06; 95% CI, 1.01-1.11) and longer axial length (per 1 mm; OR, 2.94; 95% CI, 2.19-3.95) were associated with incident myopic maculopathy. Conclusions and Relevance: Twenty-four study participants (1%) developed myopic maculopathy during the 5-year study period, which is much higher than the rate in a previous study on a Chinese population. We also confirmed that aging and longer axial length were independent and significant risk factors for myopic maculopathy. These findings should be reviewed among various populations in other parts of the world...

In a genomic screen of 331 unrelated Japanese patients, we identify a disruptive Alu insertion and a nonsense variant (p.Arg1933*) in the ciliary gene RP1, neither of which are rare alleles in Japan. p.Arg1933* is almost polymorphic (frequency = 0.6%, amongst 12,000 individuals), does not cause disease in homozygosis or heterozygosis, and yet is significantly enriched in HRD patients (frequency = 2.1%, i.e., a 3.5-fold enrichment; p-value = 9.2 × 10−5). Familial co-segregation and association analyses show that p.Arg1933* can act as a Mendelian mutation in trans with the Alu insertion, but might also associate with disease in combination with two alleles in the EYS gene in a non-Mendelian pattern of heredity. Our results suggest that rare conditions such as HRDs can be paradoxically determined by relatively common variants, following a quasi-Mendelian model linking monogenic and complex inheritance..|

Methods Thirty patients with typical RP were recruited from our hospital. The maculae of patients were examined with MP-3 and OCT. The retinal sensitivity was measured by MP-3 at 40 testing points arranged concentrically in a 16∘ diameter of the central retina, and we divided the 40 points into four zones according to degree from the fovea (2∘, 4∘, 6∘, and 8∘). We analyzed the correlation coefficients between the retinal sensitivity and the total retinal thickness (TRT), the length from the inner limiting membrane to the retinal pigment epithelium (RPE), and between the retinal sensitivity and the outer retinal thickness (ORT), the length from the outer plexiform layer to the RPE at each stimulus point. Results TRT showed moderate correlations with the retinal sensitivity at 2∘ (median ρ = 0.59 interquartile range (IQR) [0.38–0.72]), 4∘ (ρ = 0.59 [0.55–0.68]) and 6∘ (ρ = 0.60 [0.54–0.63]), and TRT was weakly-to-moderately related to the retinal sensitivity at 8∘ (ρ = 0.27 [0.19–0.48]). ORT exhibited strong correlations at 2∘ (ρ = 0.72 [0.60–0.81]), 4∘ (ρ = 0.71 [0.75–0.67]) and 6∘ (ρ = 0.70 [0.54–0.74]), and a weak-to-moderate correlations at 8∘ (ρ = 0.34 [0.29–0.53]). ORT was more strongly correlated with the retinal sensitivity compared to TRT (p = 0.018). Conclusion ORT, rather than TRT, within 6∘ eccentricity was strongly correlated with the retinal sensitivity, suggesting that measuring ORT in those areas will help evaluate the macular status and progression in RP..|

We studied 93 eyes of 68 diabetic patients who underwent OCTA (36 and 57 eyes without and with DR, respectively). Retinal capillary FD of a 2.6 × 2.6 mm2 area and four divided areas at the superficial (SCP) and deep capillary plexus (DCP) were measured. Predictions were evaluated using the area under the receiver operating characteristic curve (AUC). The diagnostic capabilities of the FDs in discriminating between eyes without DR and eyes with total or early DR were compared. Furthermore, predictions with foveal avascular zone (FAZ) area, hemoglobin A1c (HbA1c), and DM duration were also compared with FD. Prediction using FD AUC in the temporal side in the DCP (0.83) was the highest and significantly better than all other AUCs examined (P < 0.05), including discriminating between eyes without DR and with early DR (P < 0.01). Prediction using this particular AUC was also significantly better than that by FAZ area and HbA1c (P < 0.001 and <0.001, respectively). Area-divided FD in OCTA may be valuable for diagnosing retinopathy in diabetic patients..|

Cases: One was a 67-year-old female and the other was a 65-year-old male. The first case had developed swelling of the left upper eyelid associated with swollen lacrimal gland. The circlating blood showed slightly elevated value of TRAb or antibody to TSH receptor. She was diagnosed with lacrimal adenitis associated with Basedow disease. The lesion subsided after systemic treatment with cystemic corticosterodi. Similar episodes recurred three times during the following 9 years. The lacrimal tumor was totally excised after MRI showed enlarged tumor in the lacrimal gland. The lesion showed proliferation of oxyphilic cells with round nuclei in addition to eosinophilic granular cytoplasm. The second case showed a tumor in the right caruncle. The lesion was excised and was diagnosed as oncocytoma with similar findings. No recurrence had developed in both cases during one year of follow-up. Conclusion: Oncocytoma in the eyelids, including ones involving the lacrimal gland, has to considered in the differential diagnosis of ocular adnexal tumors..|

A Long-Term Follow-up Study, Ophthalmology, 10.1016/j.ophtha.2019.05.027, 126, 11, 1557-1566, 2019.11, Purpose: To present phenotypic features of 22 patients with S-antigen (SAG) mutations. Design: Retrospective cohort study. Participants: Twenty-one Japanese patients from 16 families with a homozygous c.924delA mutation and 1 patient with a homozygous c.636delT mutation in the SAG gene. Methods: Clinical records on symptoms; best-corrected visual acuity; and Goldmann perimetry, fundus photography, fundus autofluorescence (FAF), OCT, and electroretinography results were reviewed. Main Outcome Measures: Best-corrected visual acuity, Goldmann perimetry results, imaging findings, and electroretinography results. Results: Ten patients had Oguchi disease and 12 had retinitis pigmentosa (RP) with mean follow-up periods of 13.8 and 10.2 years, respectively. Retinitis pigmentosa patients were older (mean age, 56.0 years) than those with Oguchi disease (mean age, 22.1 years; P < 0.001) at the initial visit. Night blindness noted in childhood was the most common initial symptom for both Oguchi disease (80.0%) and RP (91.7%) patients. Best-corrected visual acuity in the logarithm of the minimum angle of resolution (logMAR) was well preserved in Oguchi disease patients (mean, 0.02 logMAR in both eyes) but reduced in most RP patients (mean, 1.32 logMAR [right eye] and 1.35 logMAR [left eye]). Similarly, the visual field in the retinal area was preserved in Oguchi disease patients (mean, 677 mm2 right eye and 667 mm2 left eye) and reduced in RP patients (mean, 369 mm2 right eye and 294 mm2 left eye). Fundus images revealed a characteristic golden sheen with no retinal degeneration in Oguchi disease patients, excluding 2 with macular degeneration detected by FAF, OCT, or both and 1 with mild retinal degeneration confirmed by OCT and fluorescein angiography. Pigmentary retinal degeneration most evident posteriorly was observed in RP patients, accompanied by a characteristic golden sheen in 12 of 14 patients undergoing ultra-widefield fundus imaging. OCT showed disrupted macular structure, and FAF revealed variable hypofluorescence. Electroretinography identified absent rod responses in both diseases, along with relative preservation of cone responses in Oguchi disease patients. Three patients showed progressive loss of the golden sheen based on fundus images, including 1 who demonstrated RP 26 years after the initial diagnosis of Oguchi disease. Conclusions: Retinitis pigmentosa with SAG mutations often shows a characteristic golden sheen surrounding posterior pigmentary retinal degeneration. Oguchi disease can show progressive degeneration in adulthood, rarely resulting in RP..
