RESUMO
This retrospective observational study aimed to investigate the difference in 4-year outcomes of ranibizumab or aflibercept therapy for macular neovascularization (MNV) with high myopia between pathologic myopia (PM) and non-PM. This study was conducted at Kyoto University Hospital and included consecutive treatment-naïve eyes with active myopic MNV, in which a single intravitreal ranibizumab or aflibercept injection was administered, followed by a pro re nata (PRN) regimen for 4 years. Based on the META-PM study classification, eyes were assigned to the non-PM and PM groups. This study analyzed 118 eyes of 118 patients (non-PM group, 19 eyes; PM group, 99 eyes). Baseline, 1-year, and 2-year best-corrected visual acuity (BCVA) were significantly better in the non-PM group (P = 0.02, 0.01, and 0.02, respectively); however, the 3-year and 4-year BCVA were not. The 4-year BCVA course was similar in both groups. However, the total number of injections over 4 years was significantly higher in the non-PM than in the PM group (4.6 ± 2.6 vs. 2.9 ± 2.6, P = 0.001). Four-year BCVA significantly correlated only with baseline BCVA in both non-PM (P = 0.047, ß = 0.46) and PM groups (P < 0.001, ß = 0.59). In conclusion, over the 4-year observation period, the BCVA course after anti-VEGF therapy for myopic MNV was similar in the eyes with non-PM and those with PM; however, more additional injections in a PRN regimen were required in the eyes with non-PM compared to those with PM. Thus, more frequent and careful follow-up is required for the eyes with non-PM compared with those with PM to maintain long-term BCVA.

PURPOSE: Dialysis patients are at an increased risk of developing renal cell carcinoma (RCC); however, differentiating between RCC and benign cysts can sometimes be difficult using modalities, such as computed tomography (CT) and ultrasonography. 18F-Fluorodeoxyglucose positron emission tomography (FDG-PET)/CT efficiently detects malignant tumors; however, physiological accumulation of FDG in the kidney limits its efficacy in detecting renal tumors. However, in patients with severely impaired renal function, the renal accumulation of FDG is decreased, possibly improving the detection of renal malignancies in this patient population. This study evaluated the usefulness of FDG-PET/CT as a screening tool for detecting RCC in patients with end-stage renal disease. MATERIALS AND METHODS: This prospective study recruited 150 participants from 2012 to 2016 who were on dialysis or underwent renal transplantation and were on dialysis until transplantation. FDG-PET/CT was performed to screen for RCC. Three radiologists independently evaluated the images. No protocol was defined for the additional management of positive examinations, leaving decisions to the discretion of each participant. Negative examinations were observed until the end of 2019. RESULTS: In total, 150 participants (mean age, 58 ± 13 years; 105 men) underwent FDG-PET/CT. Twenty patients (13.4%) were diagnosed as positive. Fifteen patients underwent additional examinations and/or procedures, and RCC was found in seven patients. Of the four patients who underwent surgical resection, the pathological results were clear cell RCC in one, papillary RCC in one, and acquired cystic disease-associated RCC in two. Two participants were diagnosed with RCC on bone biopsy, and one was diagnosed on dynamic CT but opted for observation. The sensitivity, specificity, and negative predictive value were 100%, 93.9%, and 100%, respectively. CONCLUSION: FDG-PET/CT was useful for detecting RCC in patients with end-stage renal disease. Our findings show the potential use of FDG-PET/CT as a screening tool for RCC in this patient population.
RESUMO
Post-gastrectomy syndrome (PGS) and body weight loss (BWL) decrease quality of life (QOL) and survival of the patient undergoing gastrectomy. We have introduced perioperative and post-discharge continuous nutritional counseling (CNC) to prevent BWL and improve QOL after gastrectomy. In the present study, we evaluated the effect of CNC on QOL using the Post-gastrectomy Syndrome Assessment Scale-45 (PGSAS-45). Eighty-three patients with gastric cancer (GC) who underwent curative gastrectomy between March 2018 and July 2019 were retrospectively analyzed. Patients received either pre-discharge nutritional counseling alone (control group, n = 45) or CNC (CNC group, n = 38) after gastrectomy. QOL at 12 months after gastrectomy was compared between the two groups. In QOL assessment, change in body weight (-7.98% vs. -12.77%, p = 0.0057), ingested amount of food per meal (7.00 vs. 6.07, p = 0.042) and ability for working (1.89 vs. 2.36, p = 0.049) were significantly better in CNC group than control group. Multiple regression analysis showed that CNC was a significantly beneficial factor for abdominal pain subscale (p = 0.028), diarrhea subscale (p = 0.047), ingested amount of food per meal (p = 0.012), Ability for working (p = 0.031) and dissatisfaction at the meal (p = 0.047). Perioperative and postoperative CNC could improve QOL in the patient undergoing gastrectomy in addition to preventing postoperative BWL.

INTRODUCTION: Pancreatic cysts are frequently observed in patients with von Hippel-Lindau disease (VHL), and they are considered clinically not important. This study aimed to evaluate the association between pancreatic cysts and diabetes mellitus (DM) in patients with VHL. METHODS: Among patients who were on a patient list at the VHL Center at Kyoto University Hospital as of December 2022, those who had undergone an upper abdominal magnetic resonance imaging study after 2010 were retrospectively evaluated. The presence or absence of DM and high glycated hemoglobin (HbA1c) levels (>6.0%) were assessed. Patients were divided into two groups: those with DM or high HbA1c levels, and those without DM or high HbA1c levels. The area of the whole pancreas, including the pancreatic cysts and tumors, the area of the pancreatic cysts, and the percentage of pancreatic cysts, calculated by dividing the area of pancreatic cysts by the area of the whole pancreas, were measured on T2-weighted magnetic resonance images and compared between the two groups. RESULTS: Thirty-six patients with VHL, comprising 22 men and 14 women, with a mean age of 36.4 years (range, 11-79 years), were identified. Seven patients had DM, and two additional patients had high HbA1c levels. The area of the pancreatic cysts (p = 0.0013) was significantly larger and the percentage of the pancreatic cysts (p = 0.0016) was significantly higher in patients with DM or high HbA1c levels (n = 9) than in patients without DM or high HbA1c levels (n = 27); however, the difference in the area of the whole pancreas was not significant (p = 0.068). CONCLUSION: Our findings suggest that patients with VHL who have a large area covered by pancreatic cysts are more likely to have DM than those without.
RESUMO
Purpose: To evaluate the efficacy and safety of faricimab injections for treatment-naïve neovascular age-related macular degeneration (nvAMD) patients, including subtypes and pachychoroid phenotypes, and identify predictive factors for visual outcomes. Methods: nvAMD patients were prospectively recruited, receiving three monthly faricimab (6 mg) injections. Best-corrected visual acuity (BCVA) two months after the last injection (month 4) was compared between subtypes, and between pachychoroid neovasculopathy (PNV) and non-PNV eyes. Regression analysis determined factors influencing month 4 BCVA. Results: The study involved 23 patients (12 typical AMD [tAMD], 10 polypoidal choroidal vasculopathy [PCV], 1 retinal angiomatous proliferation [RAP]). Eleven exhibited PNV phenotype. Significant BCVA (P = 4.9 × 10-4) and central retinal thickness (CRT) (P = 1.3 × 10-5) improvements were observed post-faricimab treatment. The therapy demonstrated favourable results for both tAMD and PCV eyes, and non-PNV and PNV eyes. Faricimab achieved dry macula in 77.3% of eyes, with subretinal fluid resolution in most cases, although intraretinal fluid (IRF) often persisted. Multivariable analysis identified external limiting membrane (ELM) presence and IRF as BCVA contributors at month 4. Conclusion: Faricimab demonstrated significant effectiveness and safety in treatment-naïve nvAMD patients, particularly for PCV and PNV eyes. ELM presence and IRF is predictive of visual outcomes.
RESUMO
PURPOSE: To investigate the predictors of macular chorioretinal atrophy, consisting of patchy atrophy (PA) at the macula and choroidal neovascularization (CNV)-related macular atrophy (CNV-MA), during treatment with ranibizumab or aflibercept for myopic CNV (mCNV) and its impact on visual outcomes. METHODS: This retrospective study included 82 eyes with treatment-naïve mCNV who were treated with pro re nata injections of ranibizumab or aflibercept. RESULTS: Nine eyes (11.0%) presented with macular PA at baseline (PA group), and 73 eyes (89.0%) did not (non-PA group). VA improved during the first year in the non-PA group; a similar trend was noted in the PA group until 3 months after initial treatment. This improvement was maintained until 24 months ( P < 0.001) in the non-PA group, but not in the PA group. In the PA group, macular chorioretinal atrophy progressed faster ( P < 0.0001), and CNV-MA was more frequent during the 2 years of treatments ( P = 0.04). Even non-PA group eyes sometimes developed CNV-MA (42% at Month 24) if they had a larger CNV and thinner subfoveal choroidal thickness at baseline, resulting in poorer visual prognosis ( P < 0.01). CONCLUSION: Macular PA at baseline was a risk factor for CNV-MA development and was associated with poor visual outcomes.

Though vascular endothelial growth factors (VEGF) and other proangiogenic factors, such as angiopoietins (Ang), may be involved in the development of neovascular age-related macular degeneration (nvAMD), only drugs that inhibit the VEGF family are available for the treatment. The newly approved anti-VEGF drug faricimab, which also inhibits Ang-2, is expected to be effective in patients with AMD refractory to conventional anti-VEGF drugs. Therefore, we prospectively investigated the efficacy of faricimab in the treatment of aflibercept-refractory nvAMD. Patients with nvAMD who had been treated with aflibercept in the last year and required bimonthly injections were recruited. 25 eyes showed persistent exudative changes immediately before the faricimab injection (baseline). In these 25 eyes, switching to faricimab did not change visual acuity or central retinal thickness 2 months after the injection; however, 56% of eyes showed reduction or complete absorption of fluid. Notably, 25% of the eyes that showed dry macula at month 2 had no fluid recurrence for up to 4 months. These results indicate that faricimab could benefit some patients with aflibercept-refractory nvAMD.

PURPOSE: To investigate factors associated with 3-month or 1-year best-corrected visual acuity (BCVA) after vitrectomy with subretinal tissue plasminogen activator injection for submacular hemorrhage (SMH) and to identify the predictors of early displacement. METHODS: This prospective cohort study included consecutive eyes with SMH complicating neovascular age-related macular degeneration or retinal macroaneurysm that underwent vitrectomy with subretinal tissue plasminogen activator injection and were followed up for at least 3 months. Parameters that correlated with 3-month BCVA, 1-year BCVA, and 2-week displacement grade (0-3) were identified. RESULTS: Twenty-nine eyes of 29 patients (73.1 ± 8.4 years; neovascular age-related macular degeneration, 25 eyes) were included. Logarithm of the minimum angle of resolution BCVA improved 3 months after the surgery (baseline, 0.76 [20/115] ± 0.35; 3-month, 0.51 [20/65] ± 0.32; P = 0.006). In multivariable analyses, 1-year logarithm of the minimum angle of resolution BCVA correlated with age ( P = 0.007, ß = 0.39) and SMH recurrence within 1 year after surgery ( P < 0.001, ß = 0.65). Two-week displacement grade correlated with the contrast-to-noise ratio of SMH ( P = 0.001, ß = -0.54). Macular hole occurred in three eyes (10%) with small SMH size and was closed in all eyes via additional vitrectomy with an inverted internal limiting membrane flap technique. CONCLUSION: The recurrence of SMH negatively affected the 1-year visual outcome after vitrectomy with subretinal tissue plasminogen activator injection for SMH. The contrast-to-noise ratio was a useful predictor of early SMH displacement, but not of 1-year BCVA. Further research is necessary to determine the optimal treatment to prevent SMH recurrence.

PURPOSE: To investigate the 10-year visual outcome and chorioretinal atrophy after a single intravitreal ranibizumab injection followed by a pro re nata regimen for myopic macular neovascularization in pathologic myopia, and to identify the factors associated with 10-year best-corrected visual acuity (BCVA). METHODS: This retrospective observational study evaluated 26 consecutive treatment-naïve eyes (26 patients) with myopic macular neovascularization in pathologic myopia who underwent a single intravitreal ranibizumab followed by a pro re nata regimen of intravitreal ranibizumab and/or intravitreal aflibercept injection and observed over 10 years. We assessed changes in BCVA and morphological parameters, including the META-PM Study category as a chorioretinal atrophy index. RESULTS: The logarithm of the minimum angle of resolution BCVA changed from 0.36 (Snellen, 20/45) ± 0.39 to 0.39 (20/49) ± 0.36 over 10 years of observation. Compared to baseline, 1-year BCVA improved ( P = 0.002), whereas 2 to 10-year BCVA was not significantly different. Total injection frequency was 3.8 ± 2.6. In none of the eyes, 10-year BCVA was 20/200 or less. Ten-year BCVA correlated with baseline BCVA ( P = 0.01, r = 0.47). The META-PM Study category progressed in 60% of eyes. There were no drug-induced complications. CONCLUSION: Best-corrected visual acuity in eyes with myopic macular neovascularization in pathologic myopia was maintained for 10 years after a single intravitreal ranibizumab followed by a pro re nata regimen without drug-induced complications. The META-PM Study category progressed in 60% of eyes, especially those with older baseline age. Early diagnosis and treatment of myopic macular neovascularization are essential to maintain good long-term BCVA.

The number of patients with syphilis has been rapidly increasing. Without treatment, syphilis can damage various organs and become life-threatening. We herein report a 29-year-old woman diagnosed with neurosyphilis, acute hydrocephalus, syphilitic uveitis combined with hypertensive retinopathy, and malignant hypertensive nephropathy. To our knowledge, this is the first report of syphilis complicated with malignant hypertensive nephropathy proven by a renal biopsy. Neurosyphilis was successfully treated with intravenous penicillin G, and severe hypertension subsequently resolved. However, delayed medical examinations and complications of syphilitic uveitis and hypertensive retinopathy resulted in irreversible visual loss. To prevent irreversible organ damage, early treatment is essential.

PURPOSE: To elucidate the clinical characteristics of atypical retinal vascular proliferation in patients with von Hippel-Lindau (VHL) disease using OCT angiography (OCTA). DESIGN: Prospective, observational study. PARTICIPANTS: Fifty-seven consecutive patients with a diagnosis of VHL disease who visited Kyoto University Hospital between January 2019 and March 2022. METHODS: Retinal hemangioblastomas (RHs) were assessed using multimodal imaging including OCTA. Retinal hemangioblastomas were classified into 2 phenotypes: nodular and flat. Nodular RHs were defined as typical RHs that were globular, well-circumscribed tumors, often accompanied with dilated feeder arterioles and draining venules. Flat RHs lacked a protruded red or colored mass, had variable and indistinct borders, and were not accompanied with feeder and draining vessels. MAIN OUTCOME MEASURES: The prevalence, distribution, and description of atypical flat RHs. RESULTS: Among 57 consecutive patients with VHL disease, 37 patients (64.9%) showed RHs in at least 1 eye. Bilateral RHs were seen in 23 patients (62.2%). Among 58 eyes of 37 patients with RHs, typical nodular RHs were detected in 54 eyes. Nodular RHs were seen mainly in the peripheral retina and occasionally in the peripapillary region, and they showed exudative changes in some cases. Flat RHs were detected in 7 eyes (12.1%). Four eyes showed only flat RHs, and 3 eyes showed both types in the same eye. Most flat RHs appeared as retinal hemorrhages or faint flat abnormal retinal vessels in the inner retina on the fundus examination, often within the macula area or peripapillary. In all eyes with flat RHs, OCTA showed abundant blood flow in the lesions. OCT revealed that flat RHs were seen mainly between the retinal nerve fiber layer and the ganglion cell layer, and occasionally within the inner nuclear layer. During a mean follow-up period of 20.4 ± 15.0 months, no flat RHs accompanied exudative change, tractional retinal detachment, or progression in size. CONCLUSIONS: Patients with VHL disease can demonstrate 2 distinct types of RHs: the classic nodular type and an atypical flat type. OCT angiography can be useful in improving the detection of atypical flat RHs, which can be difficult to detect clinically.

PURPOSE: The study aims to investigate the 7-year best-corrected visual acuity (BCVA) course after 1-year fixed regimen of intravitreal aflibercept injection (IVA) for neovascular age-related macular degeneration (nAMD) and to identify factors affecting this BCVA. METHODS: This longitudinal, observational study included 63 treatment-naïve eyes (61 patients) with nAMD, treated with 1-year fixed regimen of IVA-3 monthly injections and 4 subsequent bimonthly injections-essentially followed by PRN regimen of IVA but sometimes followed by agent switching, photodynamic therapy (PDT), or vitrectomy, as needed. We assessed BCVA changes over a 7-year period. Morphologically, we assessed central retinal thickness (CRT), central choroidal thickness (CCT), subfoveal pigment epithelial detachment (PED) height, vitreomacular traction/adhesion (VMT/VMA), epiretinal membrane (ERM), and macular atrophy involving the fovea. RESULTS: Logarithm of the minimum angle of resolution (logMAR) BCVA changed from 0.20 ± 0.24 to 0.29 ± 0.45 over 7 years. BCVA improved significantly after years 1 and 2 (P = 0.002 and 0.001, respectively) and then slowly decreased. BCVA after years 3-7 did not significantly differ from baseline. CRT and CCT decreased significantly during follow-up, while PED height did not. VMT/VMA decreased significantly, whereas ERM and macular atrophy increased significantly. Seven-year and baseline BCVA positively correlated (P = 0.007, ß = 0.35). CONCLUSIONS: BCVA was maintained for 7 years in nAMD eyes after 1-year fixed regimen of IVA, essentially followed by PRN regimen, but sometimes followed by agent switching, PDT, or vitrectomy, without severe drug-induced complications. Thus, early diagnosis and treatment of nAMD are essential for maintaining good long-term BCVA, even in eyes with relatively poor baseline vision.

PURPOSE: To investigate predictors for macular atrophy (MA) involving the fovea after photodynamic therapy (PDT) followed by pro re nata (PRN) treatment for polypoidal choroidal vasculopathy (PCV). METHODS: This prospective observational study analysed treatment-naïve eyes with symptomatic PCV without MA at baseline which were followed up for 5 years. All eyes were initially treated with PDT, followed by a PRN regimen of anti-vascular endothelial growth factor (VEGF) therapy and/or PDT. We assigned eyes with and eyes without development of MA involving the fovea 5 years after the initial treatment into MA and non-MA groups, respectively. Baseline parameters and the number of treatments were compared between the two groups. RESULTS: Seventy-two eyes of 69 consecutive patients were included, and 29 eyes of 29 patients were analysed. Twelve (41%) and 17 (59%) eyes were assigned into the MA and non-MA groups, respectively. There were significant differences in subfoveal choroidal thickness (226.2 ± 47.8 µm vs. 278.8 ± 68.1 µm, P = 0.03) and number of anti-VEGF injections (13.7 ± 9.6 vs. 5.4 ± 5.6, P = 0.007) between the MA and non-MA groups, but not in the number of PDT sessions (P = 0.71). Best-corrected visual acuity at 5 years in the MA group was lower than in the non-MA group (P = 0.048). CONCLUSION: Our long-term observation suggests that a thin subfoveal choroid at baseline and many followed anti-VEGF injections in a PRN regimen increase the risk for development of MA involving the fovea 5 years after PDT.

BACKGROUND: Body weight loss (BWL) and skeletal muscle loss (SML) are inevitable after gastrectomy for gastric cancer (GC) and can decrease patients' quality of life (QOL) and survival. OBJECTIVE: The aim of this retrospective study was to evaluate the effect of perioperative and post-discharge patient participation in continuous nutritional counseling (CNC) on post-gastrectomy BWL and SML. METHODS: Ninety-three patients with GC who underwent curative gastrectomy between March 2018 and July 2019 were analyzed. Patients received either pre-discharge nutritional counseling alone (control group, n = 49) or patient-participation CNC (CNC group, n = 44) after gastrectomy. Differences between percentage BWL (%BWL), percentage SML (%SML), and nutrition-related blood parameters between the preoperative values and those at 12 months after surgery were compared between the groups. RESULTS: Compared with the control group, %BWL was significantly lower in the CNC group at 1 month (-6.2 ± 2.5% vs. -7.9 ± 3.3%, p = 0.005), 6 months (-7.8 ± 6.6% vs. -12.3 ± 6.4%, p = 0.001) and 12 months (-7.9 ± 7.6% vs. -13.2 ± 8.2%, p = 0.002), and %SML was significantly lower in the CNC group at 12 months (-5.3 ± 10.3% vs. -12.8 ± 12%, p = 0.002). Regarding nutrition-related blood parameters, change in total cholesterol was significantly lower in the CNC group than the control group at 12 months after surgery (p = 0.02). Multivariate analysis identified no CNC as an independent risk factor for severe BWL (p = 0.001) and SML (p = 0.006) at 12 months after surgery. CONCLUSIONS: Following gastrectomy, patient-participation CNC prevented postoperative BWL and SML after surgery. These results support the induction of such a CNC program in these patients.

Purpose: To investigate the 2-year effectiveness of reduced-fluence photodynamic therapy (rf-PDT) for chronic central serous chorioretinopathy (cCSC). Design: Retrospective cohort study. Participants: A total of 223 consecutive patients with newly diagnosed cCSC with active serous retinal detachment (SRD) were included from May 2007 to June 2017 and followed up for at least 2 years. Patients who underwent ocular treatment other than cataract surgery before the beginning of recruitment and those who had macular neovascularization at baseline were excluded. Methods: All patients underwent a comprehensive ophthalmic evaluation, including measurements of best-corrected visual acuity (BCVA), slit-lamp examination, dilated fundus examination, color fundus photography, fundus autofluorescence, fluorescein angiography, indocyanine green angiography, and spectral-domain OCT. An inverse probability of treatment weighting (IPTW) methodology was applied to balance 18 baseline characteristics between patients who received rf-PDT (rf-PDT group) and those who did not receive treatment (controls). Inverse probability of treatment weighting survival analysis and regression were performed. Main Outcome Measures: The proportion of patients whose BCVA at 24 months was the same or improved compared with the baseline visual acuity (VA) (VA maintenance rate). Results: A total of 155 eyes (rf-PDT group: 74; controls: 81) were analyzed. The patients' backgrounds were well balanced after IPTW with standardized differences of < 0.10. An IPTW regression analysis revealed that the VA maintenance rate was significantly higher in the rf-PDT group than in the controls (93.6% vs. 70.9%, P < 0.001, 12 months; 85.7% vs. 69.8%, P = 0.019, 24 months). The rf-PDT group tended to show better VA improvement, but was not statistically significant (-0.06 vs. -0.008, P = 0.07, 12 months; -0.06 vs. -0.03, P = 0.32, 24 months). An IPTW Cox regression showed a significantly higher rate of complete SRD remission in the rf-PDT group (hazard ratio, 5.05; 95% confidence interval, 3.24-7.89; P < 0.001). Conclusions: The study suggests the beneficial effect of rf-PDT for cCSC for both VA maintenance and higher proportion of complete SRD remission in the clinical setting.
RESUMO
OBJECTIVE: Asymmetric features of nonfunctioning pituitary adenoma (NFPA) are poorly understood. We investigated the asymmetry in NFPA on magnetic resonance imaging. METHODS: We reviewed preoperative magnetic resonance imaging findings of patients initially treated for NFPA. The internal carotid artery (ICA) often seemed to cause an indentation in the external shape of the tumor (i.e., the ICA notch). RESULTS: Two cases with a normal pituitary gland located at the midline were excluded. The remaining 66 cases were examined. The side where the normal gland was located was defined as the normal pituitary side and the opposite side as the cavernous sinus side. The Knosp grade was significantly higher on the cavernous sinus side (P < 0.001), and the vertical distance of the ICA was significantly greater on the cavernous sinus side (P < 0.001). The ICA notch was found in 87.9% of all cases on the normal pituitary side, but in only 45.5% on the cavernous sinus side (P < 0.001). In cases with a single-side ICA notch (34 of 68), the ICA notch was found in 91.2% of cases and on the cavernous sinus side in 8.8% (P < 0.001). CONCLUSIONS: Magnetic resonance imaging of NFPA frequently shows asymmetry. The tumor does not extend laterally on the normal pituitary side but extends laterally more freely on the cavernous sinus side. The ICA notch is often found on the normal pituitary side where the position of ICA does not move. This may be useful as a preoperative sign to indicate the normal pituitary side.

PURPOSE: To identify susceptibility genes for macular neovascularization (MNV) development in central serous chorioretinopathy (CSC). DESIGN: Genome-wide survival analysis using a longitudinal cohort study. PARTICIPANTS: We included 402 and 137 patients with CSC but without MNV at their first visit from the Kyoto CSC Cohort and Kobe CSC dataset, respectively. All patients underwent detailed ophthalmic examinations, including multimodal imaging, such as fundus autofluorescence, spectral-domain OCT, and fluorescein angiography/indocyanine green angiography or OCT angiography. METHODS: We conducted a genome-wide survival analysis using the Kyoto CSC Cohort. We applied the Cox proportional hazard model to adjust for age, sex, and the first principal component. Single nucleotide polymorphisms (SNPs) with P values < 1.0 × 10-5 were carried forward to the replication in the Kobe CSC dataset. Moreover, we evaluated the contribution of previously reported age-related macular degeneration (AMD) susceptibility loci. We used FUMA and ToppFun for the functional enrichment analysis. MAIN OUTCOME MEASURES: The association between SNPs and MNV development in patients with CSC. RESULTS: Rs370974631 near ARMS2 displayed a genome-wide significant association in the meta-analysis of discovery and replication result (hazard ratio [HR]meta, 3.63; Pmeta = 5.76 × 10-9). Among previously reported AMD susceptibility loci, we additionally identified CFH rs800292 (HR, 0.39, P = 2.55 × 10-4), COL4A3 rs4276018 (HR, 0.26, P = 1.56 × 10-3), and B3GALTL rs9564692 (HR, 0.56, P = 8.30 × 10-3) as susceptibility loci for MNV development in CSC. The functional enrichment analysis revealed significant enrichment of 8 pathways (GO:0051561, GO:0036444, GO:0008282, GO:1990246, GO:0015272, GO:0030955, GO:0031420, and GO:0005242) related to ion transport. CONCLUSIONS: ARMS2, CFH, COL4A3, and B3GALTL were identified as susceptibility genes for MNV development in CSC. These 4 genes are known as susceptibility genes for AMD, whereas COL4A3 and B3GALTL were previously reported to be polypoidal choroidal vasculopathy (PCV)-specific susceptibility genes. Our findings revealed the shared genetic susceptibility between PCV and MNV secondary to CSC.

PURPOSE: To investigate predictors of early displacement of submacular hemorrhage (SMH) by simple intravitreal SF6 gas injection. METHODS: This retrospective study included 16 eyes of 16 consecutive patients (age: 74.5 ± 7.7 years; 15 men) with large SMH treated with simple intravitreal SF6 gas before inception of subretinal tissue plasminogen activator injection at our institution. The SMH displacement was graded at 1-week posttreatment as 0, 1, or 2. Central retinal thickness, central choroidal thickness, SMH height, SMH area, disease duration, use of anticoagulant or antiplatelet drugs, and contrast-to-noise ratio (CNR) of SMH on optical coherence tomography images were recorded. Correlations between displacement grading and baseline parameter were analyzed. RESULTS: Univariable correlation analysis revealed association of the 1-week displacement grading with the CNR (P = 0.004; r = -0.68) and SMH height (P = 0.03; r = -0.55). The CNR was most strongly associated with 1-week displacement on multivariable correlation analysis (P = 0.01; ß = -0.60). CONCLUSION: Findings of the present study showed that the CNR of SMH was a useful predictor of early displacement of large SMH after simple intravitreal SF6 gas injection. When vitrectomy with subretinal injection of tissue plasminogen activator is difficult in patients with large SMH, with low CNR on optical coherence tomography, simple intravitreal SF6 gas injection may be a treatment option.

PURPOSE: The purpose of this study was to investigate the predictors of retinal pigment epithelium (RPE) tear development after treatment for neovascular age-related macular degeneration using swept source optical coherence tomography angiography. METHODS: This prospective study included 152 treatment-naïve eyes with neovascular age-related macular degeneration without high myopia that were followed up for 1 year after treatment. Eligible eyes were classified into eyes with or without RPE tear development. They were matched in a 1:2 ratio. The areas of choroidal neovascularization (CNV) and RPE detachment (pigment epithelial detachment [PED]) were measured from optical coherence tomography angiography and OCT en face images, respectively. The optical coherence tomography angiography-specific parameters representing CNV status were analyzed. RESULTS: Eight (5.3%) of the 152 eyes developed RPE tears (RPE tear group). After matching, 16 eyes without RPE tears were analyzed (non-RPE tear group). The ratio of the CNV/PED area was lower in the RPE tear group than that in the non-RPE tear group (P = 0.007). The PED area was broader (P = 0.008), and PED height was greater in the RPE tear group (P = 0.04). Optical coherence tomography angiography-specific parameters did not differ between the two groups. CONCLUSION: Neovascular age-related macular degeneration with pretreatment broad PED, high PED, and small CNV area relative to the PED area has a high risk of RPE tear development after therapy. However, CNV status may not have an association.
