Abstract
Bullous retinal detachment is a rare complication in the chronic phase of central serous chorioretinopathy (CSC). Only a small subset of eyes with chronic CSC develops into the bullous variant of CSC (bCSC). In patients with bCSC, the elevated concentration of fibrin in the subretinal space leads to persistent retinal detachment and eventually, severe vision loss. We experienced a case of unilateral bCSC with a massive accumulation of subretinal fibrin. Multiple leakage points and dilated choroidal veins were also observed. The patient underwent surgical removal of subretinal fibrin and silicone oil injection followed by photodynamic therapy (PDT). After this treatment, the retina was successfully reattached, and the affected eye was free from recurrent exudative changes for more than 18 months. Massive subretinal fibrin could be surgically removed to prevent the formation of subretinal fibrosis and retinal fold, and PDT under silicone oil can control the underlying exudative changes in bCSC.

Abstract
Retinitis pigmentosa (RP) is an intractable inherited disease that primarily affects the rods through gene mutations followed by secondary cone degeneration. This cone-related dysfunction can lead to impairment of daily life activities, and ultimately blindness in patients with RP. Paradoxically, microglial neuroinflammation contributes to both protection against and progression of RP, but it is unclear which population(s) - tissue-resident microglia and/or peripheral monocyte-derived macrophages (mφ) - are implicated in the progression of the disease. Here we show that circulating blood inflammatory monocytes (IMo) are key effector cells that mediate cone cell death in RP. Attenuation of IMo and peripherally engrafted mφ by Ccl2 deficiency or immune modulation via intravenous nano-particle treatment suppressed cone cell death in rd10 mice, an animal model of RP. In contrast, the depletion of resident microglia by a colony-stimulating factor 1 receptor inhibitor exacerbated cone cell death in the same model. In human patients with RP, IMo was increased and correlated with disease progression. These results suggest that peripheral IMo is a potential target to delay cone cell death and prevent blindness in RP.

Abstract
PURPOSE To investigate the rate of the recurrence of cystoid macular edema (CME) secondary to retinitis pigmentosa (RP) after the initiation of topical dorzolamide and the recurrence risk factors. METHODS We retrospectively analyzed the data of RP patients at Kyushu University Hospital. We included patients who showed a treatment response to 1.0% topical dorzolamide. The day of treatment initiation was set as the baseline. Topical dorzolamide treatment was continued during the follow-up. The recurrence of CME (defined as a >20% increase in central subfield thickness compared to previous visit, or a central subfield thickness value that exceed baseline value) was evaluated at each follow-up visit. Risk factors for RP-CME recurrence were analyzed by Cox proportional hazards modeling. A Kaplan-Meier survival analysis was used to evaluate the time to recurrent RP-CME. RESULTS Forty RP-CME patients showed a treatment response to topical dorzolamide. During the mean 3.9-year follow-up, 14 patients exhibited recurrence; its rate was 15.6%, 34.7%, and 48.7% at 1, 3, and 5 years, respectively. A high baseline central subfield thickness was significantly associated with recurrent (hazard ratio 1.11, 95% CI: 1.05-1.18, P = 0.0004). CONCLUSION The recurrence rate of RP-CME increased with time. A high baseline central subfield thickness value was a risk factor for recurrence.

Abstract
Purpose Retinal degeneration involves neuroinflammation, and pro-inflammatory cytokines/chemokines are markedly increased in the eyes of patients with retinitis pigmentosa (RP). In this study, we investigated the changes of serum cytokines/chemokines in RP, and their relationships with visual parameters. Methods Forty-five consecutive patients with typical RP aged 20 to −39 years and 28 age-matched and gender-matched controls were included. Fifteen cytokines (interleukin [IL]-1α, IL-1β, IL-2, IL-4, IL-5, IL-6, IL-10, IL-12p70, IL-13, 1L-15, IL-17, IL-23, interferon [IFN]-γ, and tumor necrosis factor [TNF]-α, TNF-β) and 9 chemokines (eotaxin, growth-related oncogene [GRO]-α, I-309, IL-8, IFN-γ-inducible protein [IP]-10, monocyte chemotactic protein [MCP]-1, MCP-2, regulated activation normal T-cell expressed and secreted [RANTES], and thymus and activated regulated chemokine [TARC]) in the serum were simultaneously measured by a multiplexed immunoarray (Q-Plex). Relationships between these cytokines/chemokines and indices of central vision, such as visual acuity (VA), the values of static perimetry tests (Humphrey Field analyzer, the central 10-2 program), and optical coherence tomography measures were analyzed in the patients with RP. Results Among the 15 cytokines and 9 chemokines, serum IL-8 and RANTES levels were significantly increased in patients with RP compared with controls (IL-8: P < 0.0001; RANTES: P < 0.0001). Among the elevated cytokines/chemokines, the levels of IL-8 were negatively correlated with VA (ρ = 0.3596 and P = 0.0165), and the average retinal sensitivity of four central points (ρ = −0.3691 and P = 0.0291), and 12 central points (ρ = −0.3491 and P = 0.0398), as well as the central subfield thickness (ρ = −0.3961 and P = 0.0094), and ellipsoid zone width (ρ = −0.3841 and P = 0.0120). Conclusions Peripheral inflammatory response may be activated and serum IL-8 levels are associated with central vision in patients with RP.

Abstract
Purpose 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.

Abstract
PURPOSE To evaluate the retinal structure-function relationships in the macula of retinitis pigmentosa (RP) patients by comparing microperimetry-3 (MP-3) images with co-registered optical coherence tomography (OCT) images. 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.

Abstract
Purpose To accelerate the development of new therapies, an inherited retinal degeneration model in a nonhuman primate would be useful to confirm the efficacy in preclinical studies. In this study, we describe the discovery of retinitis pigmentosa in a cynomolgus monkey (Macaca fascicularis) pedigree. Methods First, screening with fundus photography was performed on 1443 monkeys at the Tsukuba Primate Research Center. Ophthalmic examinations, such as indirect ophthalmoscopy, ERGs using RETeval, and optic coherent tomography (OCT) measurement, were then performed to confirm diagnosis. Results Retinal degeneration with cystoid macular edema was observed in both eyes of one 14-year-old female monkey. In her examinations, the full-field ERGs were nonrecordable and the outer layer of the retina in the parafoveal area was not visible on OCT imaging. Moreover, less frequent pigmentary retinal anomalies also were observed in her 3-year-old nephew. His full-field ERGs were almost nonrecordable and the outer layer was not visible in the peripheral retina. His father was her cousin (the son of her mother's older brother) and his mother was her younger half-sibling sister with a different father. Conclusions The hereditary nature is highly probable (autosomal recessive inheritance suspected). However, whole-exome analysis performed identified no pathogenic mutations in these monkeys.

Abstract
PURPOSE Chronic inflammation is involved in retinitis pigmentosa (RP). We demonstrated previously that intraocular inflammatory levels, as measured by slit-lamp ophthalmoscopy or laser flare photometry, are inversely correlated with central visual function in patients with RP. Here, we investigated the relationship between serum high-sensitivity C-reactive protein (hs-CRP) and visual parameters in RP. METHODS We studied 58 consecutive typical patients with RP <40 years old and 29 age- and gender-matched controls. High-sensitivity C-reactive protein (hs-CRP) was detected by immunoturbidimetry. The relationships between hs-CRP and visual parameters including best-corrected visual acuity (BCVA), mean deviation (MD) of static perimetry tests (Humphrey Field Analyzer, the central 10-2 programme) and VA changes over the prior 5 years and MD changes over the prior 3 years were analysed in the patients with RP. RESULTS The serum hs-CRP levels of the patients with RP were significantly higher than those of the controls (0.06 ± 0.08 versus 0.03 ± 0.04 mg/dl, p = 0.0119). In the patients with RP, there was no correlation of hs-CRP with cross-sectionally assessed VA or MD, but the baseline hs-CRP was significantly correlated with the MD deterioration (r = -0.4073, p = 0.0314). CONCLUSION The average serum hs-CRP was significantly increased in the patients with RP, and higher hs-CRP was associated with faster deterioration of central visual function. These results suggest that the systemic inflammatory profile is altered and may be associated with disease progression in RP.

Abstract
PURPOSE To investigate the macular microvasculature changes by optical coherence tomography angiography (OCTA) and analyse the correlation between these changes and central visual function in patients with retinitis pigmentosa (RP). METHODS We measured the area of the foveal avascular zone (FAZ) and the foveal and parafoveal flow density (FFD and PFD, respectively) in the superficial (S) and deep (D) retinal plexus by OCTA (AngioVue) and compared these values between 73 RP patients and 36 healthy controls. We analysed the relationships between these microvasculature measurements and central visual functions such as visual acuity (VA) and the values of static perimetry tests (Humphrey Field Analyzer, the central 10-2 program) in the RP patients. RESULTS The FFD-S, PFD-S and PFD-D were significantly decreased in the RP patients compared to the controls (all p < 0.05), whereas there was no significant difference in the FAZ-S, FAZ-D or FFD-D (all p > 0.05). A subgroup analysis showed that the RP patients with VA <20/20 had increased FAZ-S compared to the controls and RP patients with VA ≥20/20 (p = 0.01 and p = 0.007, respectively). Spearman rank testing demonstrated that PFD-S and PFD-D were significantly correlated with all of the central visual parameters (all p < 0.01). The FAZ-S and FFD-S were significantly correlated with VA, and FAZ-D and FFD-D showed no significant correlation. CONCLUSION Both the superficial and deep layers of the parafoveal microvasculature are attenuated in RP and correlated with reduced central visual function. The foveal microvasculature, especially in the deep layer, was relatively preserved until mild-to-moderately advanced stages.

Abstract
Purpose Posterior subcapsular cataract (PSC) is a frequent complication in patients with retinitis pigmentosa (RP). The risk factors for PSC formation in RP are largely unknown. The purpose of this study was to investigate the risk factors for PSC. Methods We retrospectively studied a total of 322 eyes of 173 patients who were diagnosed with typical RP. We considered the following possible risk factors for PSC: age, sex, hypertension, diabetes mellitus, high myopia, asthma, history of steroid intake, and aqueous flare. Aqueous flare values were measured consecutively in 2012 and 2013 using a laser flare cell meter. The lens including PSC was examined with a slit lamp after dilation with tropicamide 1% and phenylephrine 2.5%. Results The geometric mean values of aqueous flare and mean values of visual acuity were significantly higher for the RP patients with PSC compared to those without PSC (P = 0.0003, P = 0.0004, respectively). When the aqueous flare values were assessed continuously, each 1-log-transformed increase in flare levels was associated with an elevation of the likelihood of having PSC after multivariable adjustment (odds ratio: 1.71; 95% confidence interval: 1.05-2.77). There were no significant associations of the other possible risk factors with PSC. Conclusions Our analysis demonstrated that elevated aqueous flare is a significant risk factor for PSC formation. This result might provide insights into the association of inflammation and the pathogenesis of PSC formation in RP.

Abstract
Oxidative stress is implicated in various neurodegenerative disorders, including retinitis pigmentosa (RP), an inherited disease that causes blindness. The biological and cellular mechanisms by which oxidative stress mediates neuronal cell death are largely unknown. In a mouse model of RP (rd10 mice), we show that oxidative DNA damage activates microglia through MutY homolog-mediated (MUYTH-mediated) base excision repair (BER), thereby exacerbating retinal inflammation and degeneration. In the early stage of retinal degeneration, oxidative DNA damage accumulated in the microglia and caused single-strand breaks (SSBs) and poly(ADP-ribose) polymerase activation. In contrast, Mutyh deficiency in rd10 mice prevented SSB formation in microglia, which in turn suppressed microglial activation and photoreceptor cell death. Moreover, Mutyh-deficient primary microglial cells attenuated the polarization to the inflammatory and cytotoxic phenotype under oxidative stress. Thus, MUTYH-mediated BER in oxidative microglial activation may be a novel target to dampen the disease progression in RP and other neurodegenerative disorders that are associated with oxidative stress.

Abstract
PURPOSE To investigate the changes in macular blood flow and the correlation between those changes and central visual function in patients with retinitis pigmentosa (RP). METHODS The mean blur rate (MBR), a quantitative blurring index of the laser speckle pattern that represents retinal and choroidal blood flow, was measured by laser speckle flowgraphy. Mean blur rate values in the macular area were compared between 70 patients with RP and 28 control subjects. The relationships between MBR on the one hand and, on the other, visual acuity (VA), mean deviation (MD) and averaged macular sensitivity of static perimetry tests (Humphrey Filed Analyzer, the central 10-2 program) were analysed in patients with RP. RESULTS Macular MBR was decreased to 75% in patients with RP compared with control subjects (p < 0.0001, Student's t-test). Spearman's rank testing showed that macular MBR was significantly correlated with VA (r = -0.261, p = 0.0299), MD values (r = 0.438, p = 0.0002) and averaged macular sensitivity at the central 4 and 12 points of static perimetry tests (r = 0.426 and 0.442, p = 0.0003 and 0.0002, respectively). Multivariable-adjusted analysis confirmed that MBR was independently associated with MD (p = 0.0002) and macular sensitivity at the central 4 and 12 points (p < 0.0001 and 0.0002, respectively). CONCLUSIONS Decreased macular blood flow was associated with reduced macular visual sensitivity in patients with RP. Although the cause-effect relationships remain to be elucidated, these findings suggest that vascular defects may be involved in the pathogenesis of RP such as central vision loss.

Abstract
Background Several retinal ischemic diseases can cause neovascular glaucoma (NVG). Trabeculectomy with mitomycin C (MMC) is a relatively better treatment modality in the management of eyes with NVG than other glaucoma surgeries. The aim of this study was to investigate the factors that may influence the outcome of trabeculectomy with MMC for NVG. Methods Forty-nine NVG eyes from 43 patients (26 males and 17 females) underwent primary trabeculectomy with MMC. The mean follow-up period was 16.8 ± 8.1 months (range, 6 to 34 months). Twenty-one eyes of 21 patients received intravitreal bevacizumab (IVB) 3.6 ± 1.8 days before trabeculectomy with MMC. A Kaplan-Meier survival-curve analysis was used to summarize the cumulative probability of success. We examined the relationship between the surgical outcome and the following surgical factors: gender, age, history of panretinal photocoagulation, history of cataract surgery, history of vitrectomy, preoperative IVB, NVG in the fellow eye, and postoperative complications (hyphema, choroidal detachment, and formation of fibrin) by multivariate analysis. Results The survival rate was 83.7% after 6 months, 70.9% after 12 months, and 60.8% after 24 months. The Kaplan-Meier survival curves showed no significant difference in the survival rate between the eyes with preoperative IVB (n = 21) and the eyes without preoperative IVB (n = 28) (p = 0.14). The multiple logistic regression analysis showed that postoperative hyphema (odds ratio, 6.54; 95% confidence interval, 1.41 to 35.97) was significantly associated with the surgical outcome (p = 0.02). Conclusions Postoperative hyphema was significantly correlated with the outcome of trabeculectomy for NVG. There was no significant association between preoperative IVB and postoperative hyphema or the results of trabeculectomy.

Abstract
There is no known treatment for the dry form of an age-related macular degeneration (AMD). Cell death and inflammation are important biological processes thought to have central role in AMD. Here we show that receptor-interacting protein (RIP) kinase mediates necrosis and enhances inflammation in a mouse model of retinal degeneration induced by dsRNA, a component of drusen in AMD. In contrast to photoreceptor-induced apoptosis, subretinal injection of the dsRNA analog poly(I : C) caused necrosis of the retinal pigment epithelium (RPE), as well as macrophage infiltration into the outer retinas. In Rip3(-/-) mice, both necrosis and inflammation were prevented, providing substantial protection against poly(I : C)-induced retinal degeneration. Moreover, after poly(I : C) injection, Rip3(-/-) mice displayed decreased levels of pro-inflammatory cytokines (such as TNF-α and IL-6) in the retina, and attenuated intravitreal release of high-mobility group box-1 (HMGB1), a major damage-associated molecular pattern (DAMP). In vitro, poly(I : C)-induced necrosis were inhibited in Rip3-deficient RPE cells, which in turn suppressed HMGB1 release and dampened TNF-α and IL-6 induction evoked by necrotic supernatants. On the other hand, Rip3 deficiency did not modulate directly TNF-α and IL-6 production after poly(I : C) stimulation in RPE cells or macrophages. Therefore, programmed necrosis is crucial in dsRNA-induced retinal degeneration and may promote inflammation by regulating the release of intracellular DAMPs, suggesting novel therapeutic targets for diseases such as AMD.
