Abstract
To compare visual and anatomical outcomes between peeling and embedding of epiretinal proliferation in patients with full-thickness macular holes (FTMH) with epiretinal proliferation (EP), this retrospective cohort study classified patients into two groups based on whether EP was completely peeled (peeling group, n = 25 eyes), or embedded into the hole (embedding group, n = 31 eyes) during surgery. Preoperative characteristics and postoperative outcomes, including best-corrected visual acuity and the length of the disrupted external limiting membrane and ellipsoid zone, were compared. Preoperative features including visual acuity and hole size did not differ between the two groups. All studied eyes achieved closure of the macular hole postoperatively. Visual acuity significantly improved at 3, 6, and 12 months postoperatively in both groups. The visual acuity 1-month after surgery was better in the embedding group than that in the peeling group (0.28 ± 0.29 vs. 0.50 ± 0.42 logarithm of the minimum angle of resolution, P = 0.016), although the difference was not noted after 3 months postoperatively. The embedding group showed shorter disruption of the external limiting membrane than the peeling group postoperatively (62.6 ± 40.2 μm vs. 326.2 ± 463.9 μm at postoperative 12 months, P = 0.045). In conclusion, the embedding technique during surgical repair of a FTMH with EP facilitates recovery of the outer foveal layers and promotes earlier restoration of visual function.

Abstract
PURPOSE To elucidate the clinical features and surgical outcomes of full-thickness macular hole (FTMH) with epiretinal proliferation (EP) diagnosed by both en-face and B-mode optical coherence tomography (OCT). METHOD This retrospective cohort study classified idiopathic FTMHs into two groups, based on B-scan and en-face OCT imaging: FTMH with EP (EP group) and without EP (non-EP group). The preoperative features, as well as postoperative outcomes up to 12 months, were compared between the two groups. RESULT Among 318 eyes of idiopathic FTMH that met the inclusion criteria, 59 eyes (18.6%) were in the EP group, and others were in the non-EP group. In 9 eyes (15.3%) out of the EP group, EP was not detected in the preoperative B-mode OCT but was identified through the en-face OCT. Baseline features showed a higher male proportion (47.5% vs. 27.8%, P = 0.005) and a lower incidence of vitreofoveal traction (P < 0.001) in the EP group than in the non-EP group. The EP group showed worse visual recovery than the non-EP group (- 0.23 vs. - 0.41 logarithm of the minimum angle of the resolution at 12 months, P = 0.001). CONCLUSION The en-face OCT enhances diagnostic accuracy of EP in FTMH eyes, especially in the case with smaller extent of EP. Eyes with FTMH with EP showed a worse visual recovery than FTMH without EP.

Abstract
INTRODUCTION XTEND (NCT03939767) is a multicenter, observational, prospective study of patients with treatment-naïve neovascular age-related macular degeneration (nAMD) in routine clinical practice. The study aims to examine treatment outcomes of proactive intravitreal aflibercept (IVT-AFL) treatment regimens (fixed dosing or treat-and-extend) according to local marketing labels. METHODS Study eyes received IVT-AFL injections as per the local label. The mean changes in best-corrected visual acuity (BCVA) and central subfield thickness (CST) from baseline to month (M) 12 and M24 were measured and stratified by baseline factors. Treatment exposure and safety data were evaluated. Statistical analysis was descriptive. RESULTS Overall, 1466 patients from 17 countries were treated. For the overall population, the mean ± standard deviation (SD) age was 78.7 ± 8.5 (range 50-100) years, and 891 patients (60.8%) were female. The mean ± SD baseline BCVA was 54.3 ± 20.3 letters and CST was 374 ± 126 µm. At M12 and M24, mean (95% confidence interval [CI]) BCVA change was + 4.3 (3.4, 5.3) and + 2.3 (1.3, 3.3) letters, respectively. Mean (95% CI) CST was - 106 (- 114, - 99) μm and - 109 (- 117, - 102) μm at M12 and M24, respectively. At M24, 41.5% of patients had a BCVA ≥ 70 letters. Patients received a mean ± SD of 7.7 ± 2.7 injections by M12 and 10.8 ± 5.0 injections by M24 (3.1 injections between M12 and M24). Adverse events were consistent with the known safety profile of IVT-AFL. CONCLUSION The 24-month results indicate that, in routine clinical practice, a proactive IVT-AFL regimen achieves functional improvements in patients with treatment-naïve nAMD. The proportion of patients achieving ≥ 70 letters at M24 increased, and patients with baseline BCVA ≥ 70 letters maintained vision regardless of the followed IVT-AFL label.

Abstract
PURPOSE To identify predictive factors that help determine the interval of intravitreal anti-vascular endothelial growth factor (anti-VEGF) injection after the initial resolution of diabetic macular edema (DME). METHODS This retrospective case-control study enrolled treatment-naïve DME patients who had achieved DME resolution after intravitreal anti-VEGF injections. Patients were classified into the recurrence and no-recurrence groups, depending on the development of recurrent DME after deferring intravitreal anti-VEGF injection. The demographics and clinical features, including optical coherence tomography findings, were compared between the two groups. RESULTS We enrolled 105 eyes. Sixty eyes (57.1%) belonged to the no-recurrence group, and 45 (42.9%), belonged to the recurrence group. The severity of diabetic retinopathy at baseline was related to early DME recurrence (P = 0.009). At the treatment deferring point, the non-recurrence group had both thinner central subfield thickness (289.5 ± 27.2 μm vs. 307.0 ± 38.2 μm, P = 0.011) and thinner central retinal thickness (214.9 ± 41.4 μm vs. 231.8 ± 41.2 μm, P = 0.043) compared to the recurrence group. Intraretinal cyst was observed in 34 eyes (56.7%) in the no-recurrence group and 42 eyes (93.3%) in the recurrence group at the deferring point (P < 0.001). CONCLUSION A low risk of early DME recurrence is anticipated in the eyes with foveal thinning and no intraretinal cyst when anti-VEGF injection is deferred. These predictive biomarkers can be useful for patient monitoring and determining treatment strategies for DME patients.

Abstract
PURPOSE To investigate the characteristics and natural history of treatment-naive nonexudative polypoidal choroidal vasculopathy (PCV) and to determine biomarkers predicting exudative conversion. METHODS Patients diagnosed with nonexudative PCV based on indocyanine green angiography and optical coherence tomography were included. Incidence of exudative conversion in nonexudative PCV patients and cumulative estimates for overall risk were assessed. Indocyanine green angiography and optical coherence tomography imaging-based features were analyzed to identify risk factors for exudative conversion. RESULTS The study included 42 eyes of 40 patients with nonexudative PCV. The mean follow-up duration was 54.3 ± 35.5 months. Of the 42 eyes with nonexudative PCV, exudative conversion developed in 23 eyes (54.8%) after 42.2 ± 28.3 months (range, 8-103 months). Kaplan-Meier analysis showed that the exudation-free survival at 5 years after baseline was estimated to be 53.6%. Multivariate regression analysis showed that sequentially increased protrusion of retinal pigment epithelium in the polyp area was a significant risk factor for exudation in nonexudative PCV (odds ratio = 10.16; 95% CI 1.78-57.81; P = 0.01). CONCLUSION Exudative conversion has been noted in nearly half of the nonexudative PCV cases in 5 years. The progressive protrusion of polypoidal lesions on optical coherence tomography examination may be a significant biomarker for predicting the near-term onset of exudation.

Abstract
This scientific report aims to comprehensively describe the genetic and clinical characteristics of PROM1-related retinal degeneration in Korean patients. Medical records of patients diagnosed with retinal dystrophy who underwent comprehensive ophthalmologic examination and genetic testing at Samsung Medical Center between January 2016 and April 2023 were retrospectively reviewed. Genetic testing included targeted gene panel sequencing and Sanger sequencing, with diagnosis based on the presence of a "Likely Pathogenic" or "Pathogenic Variant" in the PROM1 gene, as determined by the ACMG criteria. The study identified seven patients from five unrelated families with PROM1-related retinal degeneration, all carrying the autosomal dominant variant PROM1 p.R373C; no other PROM1 gene variants were detected. All patients exhibited degenerative retinal area within the macula, with peripheral retinal degeneration observed in five patients. Substantial interfamilial and intrafamilial variability was observed in the extent of macular and peripheral degeneration. Ultra-widefield autofluorescence imaging and fluorescein angiography aided in the detection of mild peripheral degeneration in one case. In conclusion, the autosomal dominant variant PROM1 p.R373C constitutes a significant proportion of PROM1-related retinal degeneration cases in the Korean population. The observed clinical heterogeneity may suggests the potential influence of additional genetic, epigenetic, and environmental factors on disease phenotypes.

Abstract
To investigate local ocular factors associated with the development of diabetic macular edema (DME), we classified each eye of patients with unilateral DME as the DME eyes or the fellow eyes (without DME). We compared the clinical characteristics, optical coherence tomography (OCT), and OCT angiography (OCTA), ultra-wide field fundus photography, and angiography features of each eye. As a result, fifty-five patients with unilateral DME were enrolled. Although the diabetic retinopathy stage was not different between each group of eyes, DME eyes showed a higher prevalence of venous beading and a larger area of nonperfusion region than did fellow eyes (all P < 0.05). OCTA features of DME eyes also showed a larger foveal avascular zone in the deep capillary plexus and a lower vascular density in both the superficial and deep capillary plexuses (all P < 0.05). This study highlighted ocular features reflecting retinal ischemia, such as venous beading, area of nonperfusion region, and vascular density in the central retinal area, are associated with the development of DME. OCTA and ultra-wide field fluorescein angiography may be useful for evaluating the parameters of retinal ischemia and the risk of DME development.

Abstract
Purpose The purpose of this study was to identify diabetes-related risk factors for exudative age-related macular degeneration (AMD). Methods This was a nationwide population-based cohort study using authorized clinical data provided by the Korean National Health Insurance Service. A total of 1,768,018 participants with diabetes over 50 years of age participated in the Korean National Health Screening Program between 2009 and 2012. Data on covariates, including age, sex, income level, systemic comorbidities, behavioral factors, and diabetes-related parameters, including duration of diabetes, use of insulin for diabetes control, number of oral hypoglycemic agents used, and accompanying vision-threatening diabetic retinopathy, were collected from health screening results and claims data. Patients were followed up until December 2018. Incident cases of exudative AMD were identified using registered diagnostic codes from the claims data. The prospective association of diabetes-related parameters with incident exudative AMD was investigated using the multivariable-adjusted Cox proportional hazard model. Results During an average follow-up period of 5.93 years, 7331 patients were newly diagnosed with exudative AMD. Compared to those who had diabetes for less than 5 years, individuals with diabetes for 5 years or more had a greater risk of future exudative AMD development, with a hazard ratio (95% confidence interval) of 1.13 (1.07-1.18) in the fully adjusted model. Use of insulin for diabetes control and the presence of vision-threatening diabetic retinopathy were also associated with an increased risk of exudative AMD with a hazard ratio (95% confidence interval) of 1.16 (1.07-1.25) and 1.40 (1.23-1.61), respectively. Conclusions A longer duration of diabetes, administration of insulin for diabetes control, and comorbid vision-threatening diabetic retinopathy were associated with an increased risk of developing exudative AMD.

Abstract
Importance Fungal endophthalmitis caused by contaminated medical products is extremely rare; it follows an intractable clinical course with a poor visual prognosis. Objective To report the epidemiologic and clinical features and treatment outcomes of a nationwide fungal endophthalmitis outbreak after cataract surgery as a result of contaminated viscoelastic agents in South Korea. Design, Setting, and Participants This was a retrospective case series analysis of clinical data from multiple institutions in South Korea conducted from September 1, 2020, to October 31, 2021. Data were collected through nationwide surveys in May and October 2021 from the 100 members of the Korean Retinal Society. Patients were diagnosed with fungal endophthalmitis resulting from the use of the viscoelastic material sodium hyaluronate (Unial [Unimed Pharmaceutical Inc]). Data were analyzed from November 1, 2021, to May 30, 2022. Main Outcomes and Measures The clinical features and causative species were identified, and treatment outcomes were analyzed for patients who underwent 6 months of follow-up. Results The fungal endophthalmitis outbreak developed between September 1, 2020, and June 30, 2021, and peaked in November 2020. An official investigation by the Korea Disease Control and Prevention Agency confirmed contamination of viscoelastic material. All 281 eyes of 265 patients (mean [SD] age, 65.4 [10.8] years; 153 female individuals [57.7%]) were diagnosed with fungal endophthalmitis, based on clinical examinations and supportive culture results. The mean (SD) time period between cataract surgery and diagnosis was 24.7 (17.3) days. Patients exhibited characteristic clinical features of fungal endophthalmitis, including vitreous opacity (212 of 281 [75.4%]), infiltration into the intraocular lens (143 of 281 [50.9%]), and ciliary infiltration (55 of 281 [19.6%]). Cultures were performed in 260 eyes, and fungal presence was confirmed in 103 eyes (39.6%). Among them, Fusarium species were identified in 89 eyes (86.4%). Among the 228 eyes included in the treatment outcome analysis, the mean (SD) best-corrected visual acuity improved from 0.78 (0.74) logMAR (Snellen equivalent, 20/120 [7.3 lines]) to 0.36 (0.49) logMAR (Snellen equivalent, 20/45 [4.9 lines]) at 6 months. Furthermore, disease remission with no signs of fungal endophthalmitis (or cells in the anterior chamber milder than grade 1) was noted in 214 eyes (93.9%). Conclusions and Relevance This was a retrospectively reviewed case series of a fungal endophthalmitis outbreak resulting from contaminated viscoelastic material. Findings of this case series study support the potential benefit of prompt, aggressive surgical intervention that may reduce treatment burden and improve prognosis of fungal endophthalmitis caused by contaminated medical products.

Abstract
Cardiovascular disease (CVD), the leading cause of death globally, is associated with complicated underlying risk factors. We develop an artificial intelligence model to identify CVD using multimodal data, including clinical risk factors and fundus photographs from the Samsung Medical Center (SMC) for development and internal validation and from the UK Biobank for external validation. The multimodal model achieves an area under the receiver operating characteristic curve (AUROC) of 0.781 (95% confidence interval [CI] 0.766-0.798) in the SMC and 0.872 (95% CI 0.857-0.886) in the UK Biobank. We further observe a significant association between the incidence of CVD and the predicted risk from at-risk patients in the UK Biobank (hazard ratio [HR] 6.28, 95% CI 4.72-8.34). We visualize the importance of individual features in photography and traditional risk factors. The results highlight that non-invasive fundus photography can be a possible predictive marker for CVD.

Abstract
PURPOSE To evaluate the prospective association of age-related macular degeneration (AMD) and related visual disability (VD) with the risk of depression. DESIGN This nationwide population-based cohort study used authorized clinical data provided by the Korean National Health Insurance Service. PARTICIPANTS A total of 3 599 589 individuals older than 50 years participated in the Korean National Health Screening Program in 2009. METHODS Age-related macular degeneration diagnosis and the presence of accompanying VD were verified using diagnostic codes and disability registration data. Data on covariates, including age, sex, income level, residential area, systemic comorbidities, and behavioral factors, were collected from health screening results and claims data. Patients were followed up until December 2019, and incident cases of depression were identified using registered diagnostic codes. The prospective association of AMD and related VD with new-onset depression was investigated using the multivariable-adjusted Cox proportional hazard model. MAIN OUTCOME MEASURES Hazard ratios and 95% confidence intervals (CIs) for depression development according to the presence of AMD and VD. RESULTS During an average follow-up period of 8.52 years, 1 037 088 patients received new diagnoses of depression. Patients with previous diagnoses of AMD showed a greater risk of new-onset depression, with a hazard ratio of 1.15 (95% CI, 1.13-1.17) compared with the control group in the fully adjusted model. Patients with AMD and accompanying VD showed a further increased risk of depression, with a hazard ratio of 1.23 (95% CI, 1.16-1.30). CONCLUSIONS Individuals with a diagnosis of AMD have a higher risk of depression developing in the future. The risk of depression is increased further in patients with AMD who demonstrate VD.

Abstract
OBJECTIVES Dietary fiber intake is associated with a lower risk of diabetes, cardiovascular disease, and cancer. However, it is unknown whether dietary fiber has a beneficial effect on preventing the development of chronic kidney disease (CKD). DESIGN, SETTING, PARTICIPANTS AND MEASUREMENTS Using the UK Biobank prospective cohort, 110,412 participants who completed at least one dietary questionnaire and had an estimated glomerular filtration rate ≥60 mL/min/1.73 m2, urinary albumin-to-creatinine ratio <30 mg/g, and no history of CKD were included. The primary exposure was total dietary fiber density, calculated by dividing the absolute amount of daily total fiber intake by total energy intake (g/1,000 kcal). We separately examined soluble and insoluble fiber densities as additional predictors. The primary outcome was incident CKD based on diagnosis codes. RESULTS A total of 3,507 (3.2%) participants developed incident CKD during a median follow-up of 9.9 years. In a multivariable cause-specific model, the adjusted hazard ratios (aHRs; 95% confidence intervals [CIs]) for incident CKD were 0.85 (0.77-0.94), 0.78 (0.70-0.86), and 0.76 (0.68-0.86), respectively, for the second, third, and highest quartiles of dietary fiber density (reference: lowest quartile). In a continuous model, the aHR for each +∆1.0g/1,000 kcal increase in dietary fiber density was 0.97 (95% CI, 0.95-0.99). This pattern of associations was similar for both soluble and insoluble fiber densities and did not differ across subgroups of sex, age, body mass index, hypertension, diabetes, smoking, and inflammation. CONCLUSION Increased fiber intake was associated with a lower risk of CKD in this large well-characterized cohort.

Abstract
To investigate biomarkers related to visual symptom and best corrected visual acuity (BCVA) improvement after photodynamic therapy (PDT) for central serous chorioretinopathy. This retrospective cross-sectional study involved 42 consecutive eyes, from 42 patients who underwent successful PDT, divided into two groups according to improvement in subjective visual complaints: complete (20 eyes) and incomplete recovery (22 eyes). The clinical characteristics of each group, including central foveal thickness (CFT), foveal avascular zone (FAZ) area, and degree of change in signal voiding of the choriocapillaris on optical coherence tomography angiography, were compared. Correlations between best-corrected visual acuity (BCVA) and baseline clinical features were investigated. At baseline, CFT and FAZ areas showed significant differences between the two groups (all p < 0.05). Multiple binary logistic regression analysis revealed that greater CFT predicted complete recovery from visual complaints (p = 0.002). Reduction or disappearance of signal voiding in the choriocapillaris 6 months post-PDT occurred more frequently in the complete recovery group (p < 0.05). FAZ area before PDT correlated with BCVA before and 6 months after PDT and BCVA improvement during the study period (all p < 0.05). CFT and FAZ area before PDT correlated with completeness of visual symptom recovery after PDT. Smaller FAZ area before PDT correlated with better BCVA before and after treatment.

Abstract
This nationwide population-based cohort study searched for demographic, comorbid, behavioral, and reproductive risk factors for idiopathic macular hole (MH) development using data provided by the Korean National Health Insurance Service. A total of 4,496,867 individuals aged 50-79 years who participated in the Korean National Health Screening Program in 2013 or 2014 were included. Participants were followed up until December 2018, and incident cases of idiopathic MH were identified. Prospective associations between incident idiopathic MH and various covariates were investigated using multivariable-adjusted Cox proportional hazard models. During an average follow-up period of 4.91 years, 3054 patients were newly diagnosed with idiopathic MHs. Women showed greater risk (hazard ratio of 1.71) and earlier presentation of idiopathic MH than men. Compared to the normal body mass index group, the obese group (≥ 25 kg/m2) showed a significantly lower risk of idiopathic MH. Among postmenopausal women, those with two or more children showed a greater risk of idiopathic MH than those who had not been pregnant, with a hazard ratio of 1.80. In conclusion, idiopathic MH occurred earlier and greater in women. Childbirth were associated with an increased risk of MH development, and obesity was associated with a lower risk of MH.

Abstract
This nationwide population-based cohort study evaluated the association between lipid profiles and the future risk of exudative age-related macular degeneration (AMD) using authorized clinical data provided by the Korean National Health Insurance Service. A total of 6,129,616 subjects over 50 years of age who participated in the Korean National Health Screening Program in 2013 or 2014 were included. Data on risk factors, including age, sex, comorbidities, behavioral factors, and baseline lipid profiles, including total cholesterol, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, and triglyceride (TG) levels were collected. Patients were followed-up patients until December 2018, and incident cases of exudative AMD were identified using registered diagnostic codes. During an average follow-up period of 4.91 years, 18,803 patients were newly diagnosed with exudative AMD. Compared to the lowest HDL cholesterol quartile group, the highest HDL cholesterol quartile group had a greater risk of future exudative AMD development with a hazard ratio (95% confidence interval) of 1.13 (1.08-1.18) in the fully adjusted model. The highest TG quartile group had a lower risk of exudative AMD than the lowest TG quartile group, with a hazard ratio (95% confidence interval) of 0.84 (0.81-0.88). High HDL cholesterol and low TG levels were prospectively associated with exudative AMD incidence.

Abstract
PURPOSE To compare the clinical features, treatments, and outcomes between bullous and chronic variants of central serous chorioretinopathy (CSC). DESIGN Retrospective, observational case series. PARTICIPANTS Sixty-two eyes of 44 patients with bullous-variant CSC (bvCSC) and 97 eyes of 85 patients with nonbullous CSC. METHODS We conducted a national survey between September 1, 2020, and March 31, 2021, of members of the Korean Retina Society and obtained data of patients with bvCSC from 11 retinal centers. A comparator group comprised consecutive chronic CSC patients without bullous detachment. MAIN OUTCOME MEASURES Baseline demographics and patient characteristics were compared between groups. Secondary outcomes included factors associated with visual prognosis within the bvCSC group. RESULTS Compared with the nonbullous CSC group, the bvCSC group presented at a younger age (49 vs. 52 years; P = 0.047) and with more bilateral involvement (41% vs. 14%; P < 0.001). Systemic corticosteroid use was more prevalent in the bvCSC group, both in terms of any exposure (50% vs. 20%; P = 0.001) and long-term exposure (36% vs. 9%; P < 0.001). The bvCSC group had distinct imaging features (all P < 0.05): retinal folding (64% vs. 1%), subretinal fibrin (75% vs. 13%), multiple retinal pigment epithelium tears (24% vs. 2%), and multifocal fluorescein leakages with terminal telangiectasia (36% vs. 1%). Although bvCSC patients had worse vision at diagnosis (20/80 vs. 20/44; P = 0.003), treatment response was more robust (fluid resolution by final follow-up, 84% vs. 68%; P = 0.034) even with conservative management, resulting in similar final vision (20/52 vs. 20/45; P = 0.52). History of kidney-related (odds ratio [OR] 5.4; 95% confidence interval [CI] 1.3-18.5; P = 0.045) and autoimmune/rheumatoid diseases (OR 25.4, 95% CI 2.8-195.0; P = 0.004) showed associations with the bvCSC group. Apart from vision at diagnosis (OR 0.1, 95% CI 0.05-0.36; P < 0.001), a history of renal transplantation was most predictive of visual prognoses for bvCSC eyes (OR 0.2, 95% CI 0.04-0.75; P = 0.020). CONCLUSIONS Bullous-variant CSC may be associated with pathogenic risk factors based on underlying medical conditions and systemic corticosteroid use. Poor vision at diagnosis and history of renal transplantation were associated with poor visual outcome.

Abstract
With the recent advent of high-resolution optical coherence tomography (OCT), atypical epiretinal tissue (AET), also known as epiretinal proliferation, has been frequently noted in various pathologies. AET presents as premacular tissue with homogenous medium reflectivity over the internal limiting membrane on OCT. Although AET is most frequently associated with a lamellar hole (LH), some cases of macular hole (MH) also accompany AET at the edge of the hole. MH with AET has been reported to have worse clinical and surgical outcomes than MH without AET. The imaging and histopathological findings of AET imply that the development of MH with AET may not have been driven by vitreofoveal traction. Instead, MH with AET might have evolved from LH with AET. This mini-review encompassed relevant studies on MH with AET published to date and explained the clinical, prognostic, and pathogenic significance of AET in MH in detail.

Abstract
To evaluate the real-world treatment outcomes in patients with neovascular age-related macular degeneration (nAMD) in Korea, focusing on retinal fluid resolution. This multi-institutional retrospective chart review study, analyzed medical records of patients with nAMD (age ≥ 50 years) who received their first anti-vascular endothelial growth factor (VEGF) treatment in ophthalmology clinics across South Korea between January 2017 and March 2019. The primary endpoint was the proportion of patients with retinal fluid after 12 months of anti-VEGF treatment. The association between fluid-free period and VA gains was also evaluated. A total of 600 patients were enrolled. At baseline, 97.16% of patients had retinal fluid; after 12 months of anti-VEGF treatment, 58.10% of patients had persistent retinal fluid. VA improvements were relatively better in patients with absence of retinal fluid compared with presence of retinal fluid (+ 12.29 letters vs. + 6.45 letters at month 12; P < .0001). Longer duration of absence of retinal fluid over first 12 months correlated with better VA gains at month 12 (P < .01). More than half of the study patients with nAMD had retinal fluid even after 12 months of treatment with their current anti-VEGF. Presence of retinal fluid was associated with relatively worse VA outcomes.

Abstract
Background In 2021, the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) validated a new equation for estimated glomerular filtration rate (eGFR). However, this new equation is not ethnic-specific, and prevalence of CKD in Asians is known to differ from other ethnicities. This study evaluates the impact of the 2009 and 2021 creatinine-based eGFR equations on the prevalence of CKD in multiple Asian cohorts. Methods Eight population-based studies from China, India, Russia (Asian), Singapore and South Korea provided individual-level data (n = 67,233). GFR was estimated using both the 2009 CKD-EPI equation developed using creatinine, age, sex, and race (eGFRcr [2009, ASR]) and the 2021 CKD-EPI equation developed without race (eGFRcr [2021, AS]). CKD was defined as an estimated glomerular filtration rate (eGFR) <60 mL/min/1.73m2 (G3-G5). Prevalence of eGFR categories was compared within each study and within subgroups of age, sex, body mass index (BMI), diabetes, and hypertension status. The extent of reclassification was examined using net reclassification improvement (NRI). Findings Of 67,233 adults, CKD prevalence was 8.6% (n = 5800/67,233) using eGFRcr (2009, ASR) and 6.4% (n = 4307/67,233) using eGFRcr (2021, AS). With the latter, CKD prevalence was reduced across all eight studies, ranging from −7.0% (95% CI −8.5% to −5.4%) to −0.4% (−1.3% to 0.5%), and across all subgroups except those in the BMI < 18.5% subgroup. Net reclassification index (NRI) was significant at −2.33% (p < 0.001). No individuals were reclassified as a higher (more severe) eGFR category, while 1.7%−4.2% of individuals with CKD were reclassified as one eGFR category lower when eGFRcr (2021, AS) rather than eGFRcr (2009, ASR) was used. Interpretation eGFRcr (2021, AS) consistently provided reduced CKD prevalence and higher estimation of GFR among Asian cohorts than eGFRcr (2009, ASR). Based on current risk-stratified approaches to CKD management, more patients reclassified to lower-risk GFR categories could help reduce inappropriate care and its associated adverse effects among Asian renal patients. Comparison of both equations to predict progression to renal failure or adverse outcomes using prospective studies are warranted. Funding National Medical Research Council, Singapore.

Abstract
PURPOSE To evaluate the association between high-density lipoprotein (HDL) cholesterol levels and the future risk of retinal artery occlusion (RAO). DESIGN Population-based cohort study. METHODS This study used data provided by the Korean National Health Insurance Service. A total of 9,316,212 individuals aged > 40 years who participated in the Korean National Health Screening Program in 2013 or 2014 were included. Data on risk factors - including age, sex, income level, systemic comorbidities, behavioral factors, and baseline lipid profiles - were collected from health screening results and claims data. Patients were followed up until December 2018 and incident cases of RAO were identified using registered diagnostic codes from claims data. A prospective association between HDL cholesterol level and incident RAO was investigated using the multivariable-adjusted Cox proportional hazard model. RESULTS During an average follow-up period of 4.93 years, 9878 patients were newly diagnosed with RAO. Compared with those with low HDL cholesterol levels (< 40 mg/dL), patients with high HDL cholesterol levels (≥ 60 mg/dL) had a lower risk of future RAO development, with a hazard ratio (95% CI) of 0.78 (0.73-0.83) in the age-adjusted and sex-adjusted model and 0.88 (0.83-0.95) in the full-adjusted model. The younger subgroup (< 60 years) had an HR of 0.81 in the high HDL cholesterol group compared with the low HDL cholesterol group, while the older subgroup (≥ 60 years) had an HR of 0.93 (P for interaction = .012). CONCLUSION A low HDL cholesterol level is an independent risk factor for the development of RAO.

Abstract
PURPOSE To describe the ophthalmic manifestations of familial transthyretin amyloidosis (FTA) mutations, including Asp38Ala and Thr59Lys, which have not been previously reported to have ocular involvement. METHODS This is an observational case series of prospectively collected data of 16 patients with FTA who were taking tafamidis for mild peripheral neuropathy and underwent a comprehensive ophthalmic examination at a single tertiary center, between January 2013 and March 2020. The ocular involvement of each FTA mutation type and the specific manifestations were the main outcome measures. RESULTS Six of 16 patients with FTA manifested ocular involvement. Ocular involvement was noted in two of three patients with Glu89Lys mutations having retinal deposits, retinal hemorrhages, and corneal opacity. Three of nine patients with Asp38Ala mutations and one of two patients with Thr59Lys mutations showed ocular involvement that had not been previously described. The ophthalmic findings included glaucoma, anterior lens capsule opacity, vitreous opacity, and retinal deposits. The decrease in vascular flow due to perivascular cuffing of the amyloid deposits was detected by optical coherence tomography angiography. CONCLUSION The current study newly described that two transthyretin mutation types of FTA, Asp38Ala and Thr59Lys, may manifest with ocular findings such as anterior lens capsule opacity and retinal deposits.

Abstract
PURPOSE To elucidate the significance of en-face optical coherence tomography imaging of atypical epiretinal tissue (AET) in the lamellar macular hole (LMH). METHODS This study involved 29 eyes of 29 patients who underwent surgical treatment for LMH with AET. Best-corrected visual acuity, metamorphopsia assessment (M-score), and optical coherence tomography were evaluated before and 6 months after surgery. The novel en-face optical coherence tomography parameters, such as the area of AET and hyperreflective fringe, were correlated with clinical factors before and after LMH surgery. RESULTS Preoperatively, hyperreflective fringe was noted in 25 (86.2%) patients. The splitting of the inner retina, disruption of the ellipsoid zone, the extent of foveal cavitation, symptom duration, and change in best-corrected visual acuity were correlated with the area of AET (all P < 0.05). Multivariate regression analysis revealed that a larger area of AET was associated with longer symptom duration and less improvement in postoperative vision (all P < 0.05). CONCLUSION The area of AET may represent the chronicity of LMH and is significantly associated with visual outcomes after LMH surgery. This novel en-face optical coherence tomography parameter can be used as a predictive factor for surgical outcomes in LMH with AET.

Abstract
Purpose This study aimed to establish and validate optical coherence tomography (OCT) based diagnostic criteria of high myopia. Methods This was a cross-sectional study including 100 eyes of high myopia with axial length larger than 26.5 mm and 100 control eyes, which were examined by spectral-domain OCT. Vertical and horizontal OCT of 9 mm scanning across fovea were analyzed. OCT characteristics including mirror artifact, scleral sink due to steep inclination of posterior sclera, scleral visibility, abnormality of outer retinal layer, foveoschisis, and dome-shaped macula were assessed in each group. Results The mean axial length was 28.65 ± 2.07 mm (range, 26.51–34.59 mm) in high myopia group and 23.79 ± 0.99 mm (range, 21.26–25.94 mm) in control group. Among the OCT characteristics noted at high frequency in the eyes with high myopia, three criteria achieving high sensitivity and specificity were determined: scleral sink over 500 μm, scleral visibility over 100 μm, and dome-shaped macula. Under conditions of presence of any of three criteria in either horizontal or vertical OCT scanning, the diagnostic sensitivity, specificity, positive predictive value, and negative predictive value for high myopia were found to be 95.0%, 98.0%, 98.0%, and 95.1%, respectively. In a new set of OCT images from 50 eyes with high myopia and 50 eyes of nonhigh myopia cases, the OCT-based criteria also proved similar level of diagnostic validity. Conclusions The OCT-based criteria, which directly addressed posterior scleral contour changes, may lead to an intuitive and accurate diagnosis of high myopia. Also, the criteria may contribute to early detection and monitoring of eyes that cannot be defined as high myopia but can progress. OCT may be useful for monitoring high myopia patients as OCT can detect myopia-associated retinal pathologies as well as scleral contour changes.

Abstract
This study aimed to assess detection rate of telangiectatic capillaries (TelCaps) with infrared reflectance (IR) and optical coherence tomography (OCT) images and to evaluate the clinical efficacy of IR image-guided focal laser photocoagulation of TelCaps in persistent diabetic macular edema (DME). This retrospective case series included 28 eyes of 28 patients with TelCap and persistent DME refractory to intravitreal anti-vascular endothelial growth factor or corticosteroids. The presence of TelCaps was confirmed using IR and OCT images. All patients were followed up for more than 12 months after direct focal laser photocoagulation of the TelCaps. The TelCap closure rate, changes in best-corrected visual acuity, and central subfield thickness were analyzed. On IR imaging, TelCap appeared as a characteristic hyperreflectivity within a hyporeflective spherical lesion in 85.7% of the eyes. After focal laser photocoagulation, the TelCap closure rate was 57.1% at 3 months and 71.4% at 12 months. A significant improvement in visual acuity and reduction in central subfield thickness were observed at three and 12 months after focal laser photocoagulation (all p < 0.05). The characteristic hyperreflectivity within hyporeflective lesions on the IR image in conjunction with OCT helps identify the TelCap. Our results suggest that IR imaging and OCT-guided focal laser photocoagulation of TelCaps can improve functional and anatomical outcomes in persistent DME.

Abstract
This study aimed to validate and evaluate deep learning (DL) models for screening of high myopia using spectral-domain optical coherence tomography (OCT). This retrospective cross-sectional study included 690 eyes in 492 patients with OCT images and axial length measurement. Eyes were divided into three groups based on axial length: a “normal group,” a “high myopia group,” and an “other retinal disease” group. The researchers trained and validated three DL models to classify the three groups based on horizontal and vertical OCT images of the 600 eyes. For evaluation, OCT images of 90 eyes were used. Diagnostic agreements of human doctors and DL models were analyzed. The area under the receiver operating characteristic curve of the three DL models was evaluated. Absolute agreement of retina specialists was 99.11% (range: 97.78–100%). Absolute agreement of the DL models with multiple-column model was 100.0% (ResNet 50), 90.0% (Inception V3), and 72.22% (VGG 16). Areas under the receiver operating characteristic curves of the DL models with multiple-column model were 0.99 (ResNet 50), 0.97 (Inception V3), and 0.86 (VGG 16). The DL model based on ResNet 50 showed comparable diagnostic performance with retinal specialists. The DL model using OCT images demonstrated reliable diagnostic performance to identify high myopia.

Abstract
PURPOSE To compare long-term outcomes between typical exudative age-related macular degeneration (TexAMD) and polypoidal choroidal vasculopathy (PCV), and to investigate factors related to the outcomes. METHODS This retrospective study included 319 eyes (164 with TexAMD and 155 with PCV) treated with anti-vascular endothelial growth factor and followed more than 5 years. The primary outcome was visual acuity (VA) change from baseline to final visit. Linear regression analyses were used to determine factors associated with final VA. RESULTS Baseline logMAR VA was 0.7 ± 0.5 in the TexAMD group and 0.5 ± 0.4 in the PCV group (p < 0.001). After a mean follow-up of 9 years, final VA was also significantly worse in the TexAMD group than in the PCV group (0.9 ± 0.6 vs. 0.6 ± 0.5; p < 0.001). The PCV group showed longer maintenance of improved vision and later onset of significant visual decline than the TexAMD group. In multivariate analysis, loss to follow-up, worse baseline VA, macular atrophy, and subretinal fibrosis were significantly associated with poor final VA in both groups. CONCLUSION PCV eyes showed relatively favorable long-term visual outcome than TexAMD eyes. The results of this study emphasized the importance of compliance with treatment, along with other well-known prognostic factors.

Abstract
Purpose To describe myopic nontractional foveal detachment associated with pachychoroid diseases. Methods This retrospective study included 15 myopic eyes which had nontractional serous foveal detachment. The eyes were divided into myopic central serous chorioretinopathy (CSC) group (n = 8) and a myopic pachychoroid neovascularization (PNV) group (n = 7) according to the presence of type 1 choroidal neovascularization on multimodal imaging. The findings of multimodal imaging and treatment response were described. Results In myopic CSC group, pachychoroid features such as pachyvessels, choroidal vascular hyperpermeability and punctate hyperfluorescent spots were noted in 8 eyes (100%), 8 eyes (100%), 5 eyes (62.5%) respectively. The above features were noted in 7 eyes (100%), 5 eyes (83.3%), 5 eyes (83.3%), respectively, in the myopic PNV group. Five of 8 eyes in myopic CSC and all 7 eyes received treatment including anti-vascular endothelial growth factor injection and/or photodynamic therapy. However, only five eyes had a complete response. Conclusions The pachychoroid phenotype may coexist with high myopia and lead to myopic nontractional serous foveal detachment. Our series suggest that the response to treatment for these conditions would be limited.

Abstract
Importance The neuroprotective action of sex hormones has been described. Data on the association between 5α-reductase inhibitor (5-ARI), a male sex hormone antagonist, and macular abnormalities are lacking to date. Objective To assess the association between the use of 5-ARI for treatment of benign prostate hypertrophy and/or androgenic alopecia in men and macular abnormalities on optical coherence tomography imaging. Design, Setting, and Participants This retrospective case-control, cross-sectional study included electronic health record data from 31 male patients who showed foveal cavitation on spectral-domain optical coherence tomography imaging from January 1, 2016, to June 30, 2019. Exposures Receipt of 5-ARI for at least 2 years as treatment of benign prostate hypertrophy and/or androgenic alopecia. Main Outcomes and Measures Clinical data and multimodal imaging findings and the proportion of 5-ARI users. Results Among 31 male patients with foveal cavitation, 5-ARI was used for 10 of 14 patients (71.4%) with macular abnormalities of unknown origin and for 2 of 17 patients (11.8%) with macular abnormalities of well-known specific origin (P = .001). The mean age of these 14 patients was 74.7 years (range, 60.1-88.0 years). In the 15 eyes of 10 patients who had received 5-ARI for macular abnormalities of unknown origin, mean (SD) age was 72.8 (7.5) years, mean (SD) length of time receiving 5-ARI was 72.3 (39.2) months, and mean (SD) logMAR visual acuity was 0.08 (0.10) (Snellen equivalents, 20/24 [20/25]). Optical coherence tomography imaging showed a disease spectrum ranging from tiny foveal cavitation to an impending macular hole. Of the total male patients, 80.0% (8 of 10) had no symptoms. Conclusions and Relevance The findings suggest that macular abnormalities associated with 5-ARI are characterized by cystoid abnormalities and foveal cavitation in male patients, which may progress to outer foveal defect and macular hole. These macular abnormalities associated with a male sex hormone antagonist suggested by this investigation warrant further corroboration.

Abstract
This retrospective, consecutive interventional study investigated the long-term clinical outcomes of combined vitrectomy with intraoperative dexamethasone implants for non-tractional refractory diabetic macular edema (DME). The study included 43 eyes from 39 participants with DME that had continued for more than 6 months despite repeated non-surgical treatment. Postoperative changes in best-corrected visual acuity (BCVA) and central macular thickness (CMT) were evaluated over 3 years. A Kaplan-Meier curve was obtained for any additional non-surgical treatment, and the average number of non-surgical treatments required for DME before and after surgery was compared. Other postsurgical complications were also investigated. The logMAR BCVA improved from 0.526 ± 0.417 (20/67) preoperatively to 0.294 ± 0.374 (20/39) 3 years postoperatively (p < 0.001, generalized estimating equation). The CMT improved from 478 ± 122 μm preoperatively to 314 ± 90 μm 3 years postoperatively (p < 0.001, generalized estimating equation). Additional non-surgical treatment was not required for 29 (67%) eyes. The average number of annual non-surgical treatments decreased from 5.04 times preoperatively to 0.34 times postoperatively. Seventeen (40%) eyes developed temporary ocular hypertension after surgery, which normalized after antihypertensive eye drop instillation. In conclusion, vitrectomy combined with intraoperative dexamethasone implantation provides satisfactory long-term clinical outcomes for non-tractional refractory DME while reducing the number of intraocular injections for DME.

Abstract
Purpose To investigate the impact of the metabolic syndrome (METS) on the incidence of retinal vein occlusion (RVO). Methods This is a retrospective cohort study using Korean National Health Insurance System data. 23,153,600 subjects without previous history of RVO underwent a National Health Screening Program examination between 2009 and 2012. They were monitored for RVO development (registration of diagnostic code for RVO) until 2015. Presence of METS was defined using the data from the National Health Screening Program examination according to the revised criteria of the National Cholesterol Education Program Adult Treatment Panel III. A multivariate adjusted Cox regression analysis was used to reveal hazard ratios and 95% confidence interval for RVO development in the presence of METS. Results The age of the subjects was 47.64 ± 13.51 years. In this cohort, 11,747,439 (50.7%) were male, 11,406,161 (49.3%) were female, and 6,398,071 subjects (27.6%) were diagnosed with METS. The overall incidence of RVO was 0.947 per 1000 person-years. The adjusted hazard ratio of RVO in the presence of METS was 1.458 (95% confidence interval, 1.440–1.475; P < 0.001) after adjusting for age, sex, smoking status, alcohol consumption, physical activity, and income. Among all of the criteria for METS diagnosis, elevated blood pressure was the greatest risk for RVO development (adjusted hazard ratio, 1.610; 95% confidence interval, 1.589–1.631; P < 0.001). Conclusions METS and each of diagnostic criteria was associated with an increased risk of RVO development. Elevated blood pressure seems to be especially important factors for RVO development. Translational Relevance Our results provide information about the link between METS and RVO.

Abstract
We aimed to evaluate the association between obesity and the incidence of retinal vein occlusion (RVO) with and without diabetes mellitus (DM).This is a retrospective cohort study using Korean National Health Insurance System data. The participants were 23,061,531 adults older than 20 years who received a health examination at least once between 2009 and 2012, and all patients were observed for RVO development until 2015. We used a multivariate adjusted Cox regression analysis to evaluate the association between RVO and body mass index (BMI) with and without DM. The analysis were evaluated via a hazard ratio (HR) and 95% confidence interval (CI). The age-, sex-, and multivariable-adjusted HRs for RVO were stratified by BMI. This population-based study revealed evidence that obesity has a different effect on the incidence of RVO in the presence and absence of DM.In people with DM, a lower BMI was associated with an increased risk of RVO, and a higher BMI was associated with a lower risk for RVO. In people without DM, the correlation was reversed: a lower BMI was associated with a lower risk for RVO and vice versa.

Abstract
Background To evaluate the detailed structural profile of dome-shaped macula and its association with myopic macular complications. Methods This retrospective study included 147 eyes of 93 patients who were diagnosed with degenerative myopia. The height of the scleral dome and diameter of the dome base were measured via enhanced depth imaging optical coherence tomography images with 1:1 μm setting. Spherical equivalent and best-corrected visual acuity were compared in eyes with and without dome-shaped macula. In eyes with dome-shaped macula, the height and diameter of the dome were compared in eyes with and without myopic macular complications including choroidal neovascularization, myopic foveoschisis, and macular hole. Results Dome-shaped macula was noted in 60 eyes (40.8%) of 42 patients. The mean height of the dome in the eyes with dome-shaped macula was 126.5 ± 69.4 μm (53 to 345 μm) and the mean diameter of the dome base was 2862.1 ± 794.9 μm (1567 μm to 4886 μm). In comparing eyes with and without dome-shaped macula, eyes with dome-shaped macula had higher myopia (− 13.7 diopters vs − 12.1 diopters, P = 0.022). There was no difference in visual acuity in eyes with or without dome-shaped macula (P = 0.132). The height and diameter of the dome in eyes with and without myopic foveoschisis were 78.6 ± 20.6 μm and 134.9 ± 71.6 μm, 2499.2 ± 303.1 μm and 2969.3 ± 645.7 μm, respectively (P = 0.009 and P = 0.017). However, the height and diameter of the dome were not related to the incidence of a macular hole (P = 0.324 and P = 0.605) and choroidal neovascularization (P = 0.835 and P = 0.905). Conclusions The prevalence of dome-shaped macula was about 40% in the eyes with degenerative myopia. Although dome-shaped macula was associated with higher degrees of myopia, a prominent dome seemed to be protective against myopic foveoschisis.

Abstract
The advent of anti-vascular endothelial growth factor (VEGF) therapies has remarkably improved the functional outcomes of neovascular age-related macular degeneration (nAMD) patients. However, there are guidelines on how to start treatment, the guidelines for discontinuing treatment are not yet clear. In this respect, the treat-extend-stop (TES) protocol have showed us the possibility of discontinuing treatment. In this study, we tried to investigate optical coherence tomography angiography (OCTA) biomarkers related to recurrence of neovascular activity in eyes with nAMD undergoing treatment using TES protocol. A total of 134 eyes with nAMD were divided into two groups (stop, non-stop) depending on whether they met criteria for stopping anti-VEGF treatment. Quantitative and qualitative OCTA parameters including the morphologic pattern of choroidal neovascularization (CNV) were compared between groups. Of these, 44 eyes (32.8%) were in the stop group and 90 eyes (67.2%) were in the non-stop group. In multivariate regression analysis, closed-circuit pattern of CNV and the presence of peripheral loop were associated with the non-stop group (all p < 0.001). Our results imply that the morphologic appearance of CNV on OCTA after anti-VEGF treatment may be a useful biomarker to predict weaning from treatment.

Abstract
PURPOSE To investigate association between the development of retinal vein occlusion (RVO) and blood high-density lipoprotein cholesterol (HDL-C). DESIGN A retrospective, nationwide, population-based cohort study. METHODS This study was set in the Republic of Korea and included 23,149,403 people ≥20 years of age who underwent the Korean National Health Screening Program examination between January 2009 and December 2012. Among them, the RVO group was composed of patients with an initial diagnosis of RVO made between 2009 and 2015 (n = 117,639). The earliest claim with an RVO diagnostic code was considered as the incident time. The predictive value of HDL-C level for RVO was analyzed using hazard ratios. The primary outcome measure was the incident cases of RVO. RESULTS Subjects with RVO were generally older; had high body mass index, waist circumference, fasting blood glucose, blood pressure, total and low-density lipoprotein cholesterol, and triglyceride values, and low glomerular filtration rate and HDL-C values; and were more likely to experience diabetes mellitus and hypertension compared with the non-RVO group. The fully adjusted hazard ratio of RVO was 1.12 (95% confidence interval 1.10-1.14) in the lowest quartile of HDL-C versus in the highest quartile. The association between the development of RVO and HDL-C was higher those with a younger age, male sex, current smoking habit, diabetes mellitus, and hypercholesterolemia. In addition, we observed a significant synergistic effect of low HDL-C level with obesity and hypertension. CONCLUSION This is the first nationwide population-based epidemiologic study evaluating the association between HDL-C level and the risk of RVO development. A significant association between low HDL-C and RVO development was found.

Abstract
This study was conducted to establish the optimal application conditions of barley straw biochar (BC) for rice cultivation and to determine the effects of combined application of BC and inorganic fertilizer (IF) on rice cultivation in a paddy field. Based on the characteristics of rice growth in pot-based experiments, the selected optimal application conditions of BC were application of 20 ton ha-1 at 14 days before rice transplanting. The effects of BC application on rice cultivation in a paddy field when using those conditions were then evaluated. Each treatment was separated by a control (Cn), IF, BC, and combined BC + IF treatments, respectively. The rice yields in the BC + IF treatment were 38.6, 21.7, and 24.5% greater than those in the Cn, IF, and BC treatments, respectively. In addition, yield components of rice were significantly improved in the BC + IF treatment relative to the other treatments. Following rice harvest, soil status was improved, showing greater soil aggregation stability, decreased bulk density, and increased porosity in the BC-treated areas compared to those in the Cn- and IF-treated areas. At the time of rice harvesting, soil chemical properties such as pH, EC, SOC, TN, Avail. P2O5, and CEC in the BC-treated areas were improved over those in other areas. The results of this study indicate that using BC as a soil amendment is effective at improving rice cultivation and can benefit the soil environment.

Abstract
Purpose To evaluate the 1-year results of vitrectomy performed in combination with intraoperative dexamethasone implant for tractional and nontractional refractory diabetic macular edema (DME). Methods Thirteen eyes from 13 subjects who were diagnosed with tractional DME and 17 eyes from 17 subjects who were diagnosed with nontractional refractory DME underwent vitrectomy and dexamethasone implant injection. Changes in best-corrected visual acuity (BCVA) and central macular thickness (CMT) during the one year following vitrectomy were evaluated in each group. Additionally, changes in intraocular pressure and other complications were investigated postoperatively. Results In eyes with tractional DME, a statistically significant improvement in BCVA was noted at 3, 6, and 12 months, and a statistically significant improvement in CMT was noted at 1, 3, 6, and 12 months from baseline after vitrectomy (p < 0.05). In eyes with nontractional refractory DME, a statistically significant improvement in BCVA was noted at 12 months, but there were no significant improvements in CMT despite the tendency to decrease from baseline. Sixteen (53.3%) of the 30 eyes included in this study showed intraocular pressure elevation, which was addressed using antiglaucoma medication, and there were no other severe complications. Conclusions Vitrectomy combined with intraoperative dexamethasone implant may be safe and effective in treating DME, especially tractional DME. In this study, patients with nontractional DME required more additional treatments and time for anatomical and functional improvement compared to patients with tractional DME.

Abstract
BACKGROUND Limited data exist on real-world treatment patterns for diabetic macular edema (DME) in Korea. In this study, we investigated DME treatment patterns from 2009 to 2014 and the impact of baseline treatment on healthcare resource utilization and visual acuity (VA) outcomes. METHODS A retrospective cohort chart review of DME patients treated at 11 hospital ophthalmology clinics between January 1, 2012 and December 31, 2013 was conducted. We collected data on demographics, healthcare resource utilization (clinic visits, treatment visits, and visits for ocular investigations), distribution of DME treatments, and VA. RESULTS Overall, 522 DME patients (men, 55.2%; mean age, 59 years; mean HbA1c [n = 209], 8.4%) with 842 DME eyes were evaluated. For all treatments, healthcare resource utilization was significantly higher during the first 6 months versus months 7-12, year 2, or year 3 (P ≤ 0.001), but was highest for patients whose first treatment was an anti-vascular endothelial growth factor (VEGF) treatment (visits/quarter; anti-VEGF, 1.9; corticosteroids, 1.7; laser, 1.4). Use of macular laser therapy decreased (44% to 8%), whereas use of anti-VEGF injections increased (44% to 69%) during the study period. However, VA improvement was not commensurate with healthcare resource utilization of anti-VEGF treatment (mean VA gain, 2.7 letters). CONCLUSION A trend toward increasing use of intravitreal anti-VEGF injections for DME treatment was observed in Korea. However, the frequency of dosing and monitoring was lower in clinical practice versus major clinical trials, which may have led to the less-than-favorable improvements in visual outcomes.

Abstract
We identified clinical characteristics and risk factors of choroidal neovascularization (CNV) in eyes with prior episode of central serous chorioretinopathy (CSC). This retrospective case-control study included those initially diagnosed with CSC and developed CNV secondarily (Group 1, n = 16), those diagnosed with CNV in eyes of previous putative CSC (Group 2, n = 14), and those initially diagnosed with CSC, and did not develop CNV secondarily, as a control group for Group 1 (Group 3, n = 250). Clinical characteristics including treatment outcomes were assessed. Demographics and multimodal imaging at the time of CSC diagnosis of secondary CNV were compared between the groups to identify risk factors. Duration from diagnosis of CSC to development of CNV in Group 1 was 40.2 ± 42.0 months. Classic CNV was noted in 23 (76.7%) eyes. After treatment with intravitreal antiangiogenics with average of 4.9 times, visual acuity improved in Group 1 and Group 2 (p = 0.002). Multivariate analysis revealed that systemic hypertension, pigmentary changes, and double layer sign were associated with development of CNV secondary to CSC (p < 0.05). Hypertension, pigmentary changes, and double layer sign were independent risk factors for CNV secondary to CSC. The CNV's responded well to treatment, resulting in improved vision.

Abstract
The purpose of this study was to evaluate the efficacy of intravitreal aflibercept for active polypoidal choroidal vasculopathy (PCV) without active polyps and to identify prognostic factors. We enrolled 40 eyes from 40 patients who manifested PCV with exudation but without active polyps after prior treatment with photodynamic therapy (PDT) and/or anti-vascular endothelial growth factor (VEGF) other than aflibercept. Participants were initially given three consecutive intravitreal injections of aflibercept at 1-month intervals, followed by injections every 2 months in the maintenance phase. Spectral-domain optical coherence tomographic and indocyanine green angiographic features were assessed to determine associations between anatomical parameters and visual outcomes 14 months later. Mean visual acuity improved from 61.5 ± 11.1 letters at baseline to 68.1 ± 13.6 letters at 14 months (P = 0.001). Better vision and a smaller branching vascular network at baseline and 1 month after three monthly injections (visit 4) were associated with better final vision (P < 0.001). The presence of an inner retinal cyst at visit 4 was significantly related to worse final vision (P = 0.011). Intravitreal aflibercept improved the visual and anatomical outcomes of PCV with exudation from BVN after pre-treatment with PDT and/or anti-VEGF other than aflibercept. Better vision, smaller lesion size, and absence of an inner retinal cyst after induction therapy may predict better visual outcome.

Abstract
Purpose To evaluate changes in the peripapillary retinal nerve fiber layer (RNFL) thicknesses using spectral-domain optical coherence tomography (SD-OCT) in hydroxychloroquine (HCQ) users. Methods The medical records of HCQ users were retrospectively reviewed. In these HCQ users, an automated perimetry, fundus autofluorescence photography, and SD-OCT with peripapillary RNFL thickness measurements were performed. The peripapillary RNFL thicknesses were compared between the HCQ users and the control groups. The relationships between the RNFL thicknesses and the duration or cumulative dosage of HCQ use were analyzed. Results This study included 77 HCQ users and 20 normal controls. The mean duration of HCQ usage was 63.6 ± 38.4 months, and the cumulative dose of HCQ was 528.1 ± 3.44 g. Six patients developed HCQ retinopathy. Global and six sectoral RNFL thicknesses of the HCQ users did not significantly decrease compared to those of the normal controls. No significant correlation was found between the RNFL thickness and the duration of use or cumulative dose. The eyes of those with HCQ retinopathy had temporal peripapillary RNFL thicknesses significantly greater than that of normal controls. Conclusions The peripapillary RNFL thicknesses did not change in the HCQ users and did not correlate with the duration of HCQ use or cumulative doses of HCQ. RNFL thickness is not a useful biomarker for the early detection of HCQ retinal toxicity.

Abstract
BackgroundTo elucidate the clinical characteristics of a full-thickness macular hole (FTMH) with atypical epiretinal tissue (AET), and expand the spectrum of pathogenesis of MH.MethodsThis study involved 225 consecutive eyes of 211 patients who underwent surgery for an idiopathic FTMH. Eyes were divided into two groups according to the presence of AET. Tomographic features at baseline, closure rate of the MH and visual outcomes were compared between the two groups.ResultsAET was detected in 26 (11.6%) among 225 eyes. Overall closure of the MH was noted in 92.3% of eyes with AET and 99.5% of eyes without AET at 12 months postoperatively (p=0.003). At 12 months postoperatively, the mean logarithm of the minimum angle of resolution visual acuity in eyes with and without AET was 0.38 and 0.21, respectively (p=0.046). At baseline, eyes with AET more frequently had splitting of the inner retina but fewer intact photoreceptors compared with eyes without AET (19.2% vs 2.5%, and 57.7% vs 89.9%, p<0.001, respectively).ConclusionsThe presence of AET in an FTMH was related to poorer anatomical success and less visual recovery after surgery, suggesting that AET reflects a chronic pathogenic process involving more severe damage to the foveal tissue.

Abstract
PURPOSE To evaluate the effect of dexamethasone intravitreal implant for macular edema (ME) following branch retinal vein occlusion (BRVO) in Korean patients. METHODS We performed a prospective, open-label, multicenter study of 71 patients with ME for < 3 months. Retreatment was allowed ≥4 months from the last injection. RESULTS At 6 and 12 months, mean ± SD best-corrected visual acuity (BCVA) improvement was 18.6 ± 12.9 and 15.3 ± 15.0 letters, respectively. Approximately 70% of maximum treatment response was observed after 1 week. Over the 12-month period, 32 and 49% of patients received 1 and 3 injections, respectively, with a mean ± SD interval of 20.0 ± 5.0 weeks. Patients who required 3 injections had higher central retinal thickness (CRT) and larger macular nonperfusion at baseline compared to those requiring only 1 injection. Adverse events included increased intraocular pressure (35%) and newly diagnosed cataract (16%). CONCLUSIONS Intravitreal dexamethasone treatment with an interval of ≥4 months provides rapid and significantly better improvement in BCVA and CRT in patients with BRVO-associated ME.

Abstract
Objective Choroidal metastases (CMs) are the most common intraocular tumor. Management is mainly radiation therapy with goals of pain control and visual improvement. However, many radiation-related complications are reported. Since gamma knife radiosurgery (GKS) for CM was first reported in 1995, few cases have been reported. We report 7 cases of CMs treated with GKS. Methods From April 2011 to November 2014, 7 patients with CM underwent GKS. Their median age at treatment was 64 years (range, 51–71 years). Four males and three females were treated. Lung cancer was the most common primary pathology, followed by renal cell carcinoma and stomach cancer. Four patients had multiple cerebral lesions and were treated simultaneously for choroidal lesions. The median marginal dose of 20 Gy (range, 15–25 Gy) was administered at the 50% isodose line. Results Median follow-up period after GKS was 8 months (range, 2–38.3 months). Four patients expired due to underlying malignancy progression. Except for two patients who were not followed with magnetic resonance image after GKS, all patients showed size reduction in the treated lesions, but a new choroidal lesion appeared in one patient and one recurred. Six of seven patients reported subjectively improved visual symptoms. Visual acuity improved in 2 patients, and 2 were stable upon objective examination. One patient showed no improvement in visual acuity, but ocular pain was relieved; another patient showed improved vision and tumor remission, but visual deterioration recurred. Conclusion GKS was shown to be safe and effective and should be considered for CM treatment.

Abstract
PURPOSE The aim of this study was to investigate the incidence and associated clinical factors of delayed absorption of subretinal fluid (SRF) after surgery for rhegmatogenous retinal detachment. METHODS This study involved 36 eyes of 36 consecutive patients who underwent successful surgery for rhegmatogenous retinal detachment. A complete ophthalmologic evaluation, including clinical fundus examination, optical coherence tomography, and indocyanine green angiography, was conducted before and after surgery. Delayed absorption was defined as the presence of residual concave SRF or an SRF bleb at 6 months after surgery. Clinical factors and choroidal features on indocyanine green angiography were compared according to the presence and absence of delayed absorption. RESULTS Eighteen of 36 eyes (50%) showed delayed absorption. Macular involvement and worse preoperative visual acuity were significantly related to the presence of delayed absorption (p = 0.001 and p = 0.034, respectively). On indocyanine green angiography, preoperative choroidal vascular hyperpermeability was noted in 70% of eyes with delayed absorption and in 14% of eyes without it (p = 0.010). CONCLUSIONS Delayed absorption of SRF after retinal reattachment surgery was not rare, with a 50% of incidence in this study. Macula-off status was significantly related to the incidence of delayed SRF absorption, and choroidal features such as choroidal vascular hyperpermeability might be responsible in part, possibly through the resultant exudative property of choroid.

Abstract
PURPOSE To investigate the prevalence and risk factors for an epiretinal membrane (ERM) in Korean population. METHODS Using the database of the Korea National Health and Nutrition Examination Survey from 2008 through 2012, 14,772 participants 40 years of age or older with gradable fundus photographs were included. The presence of ERM was determined by using fundus photographs. The prevalence of ERM was estimated and possible risk factors including systemic factors, nutritional status, and blood tests were analyzed via multiple logistic regression analyses. RESULTS The prevalence of ERM was 2.9% (95% confidence interval [CI], 2.6% to 3.3%). On multiple logistic regression analysis, the prevalence of ERM was affected by age. The odds ratios (ORs) against the forties were 2.70, 5.48, and 5.69 in the fifties, sixties, and seventies, respectively. ERM was also significantly affected by cataract surgery (OR, 2.82; 95% CI, 2.08 to 3.81) and by the increase in intake of 100-mg calcium (OR, 1.05; 95% CI, 1.00 to 1.11). ERM had negative associations with red blood cell count (OR, 0.66; 95% CI, 0.45 to 0.95). CONCLUSIONS The estimated nation-wide prevalence of ERM in Korea is 2.9%. The presence of ERM in the general population is associated with age, cataract surgery, increased dietary calcium, and a low red blood cell count.

Abstract
Previously, we showed that corticotrophin-releasing hormone immunoreactive (CRH-IR) neurones in a septal structure are associated with stress and the hypothalamic-pituitary-adrenal axis in birds. In the present study, we focused upon CRH-IR neurones located within the septal structure called the nucleus of the hippocampal commissure (NHpC). Immunocytochemical and gene expression analyses were used to identify the anatomical and functional characteristics of cells within the NHpC. A comparative morphometry analysis showed that CRH-IR neurones in the NHpC were significantly larger than CRH-IR parvocellular neurones in the paraventricular nucleus of the hypothalamus (PVN) and lateral bed nucleus of the stria terminalis. Furthermore, these large neurones in the NHpC usually have more than two processes, showing characteristics of multipolar neurones. Utilisation of an organotypic slice culture method enabled testing of how CRH-IR neurones could be regulated within the NHpC. Similar to the PVN, CRH mRNA levels in the NHpC were increased following forskolin treatment. However, dexamethasone decreased forskolin-induced CRH gene expression only in the PVN and not in the NHpC, indicating differential inhibitory mechanisms in the PVN and the NHpC of the avian brain. Moreover, immunocytochemical evidence also showed that CRH-IR neurones reside in the NHpC along with the vasotocinergic system, comprising arginine vasotocin (AVT) nerve terminals and immunoreactive vasotocin V1a receptors (V1aR) in glia. Hence, we hypothesised that AVT acts as a neuromodulator within the NHpC to modulate activity of CRH neurones via glial V1aR. Gene expression analysis of cultured slices revealed that AVT treatment increased CRH mRNA levels, whereas a combination of AVT and a V1aR antagonist treatment decreased CRH mRNA expression. Furthermore, an attempt to identify an intercellular mechanism in glial-neuronal communication in the NHpC revealed that brain-derived neurotrophic factor (BDNF) and its receptor (TrkB) could be involved in the signalling mechanism. Immunocytochemical results further showed that both BDNF and TrkB receptors were found in glia of the NHpC. Interestingly, in cultured brain slices containing the NHpC, the use of a selective TrkB antagonist decreased the AVT-induced increase in CRH gene expression levels. The results from the present study collectively suggest that CRH neuronal activity is modulated by AVT via V1aR involving BDNF and TrkB glia in the NHpC.

Abstract
OBJECTIVE Bone morphogenetic proteins (BMP) belong to the transforming growth factor beta superfamily of proteins. This study was performed to evaluate the association of BMP gene polymorphisms with acute renal allograft rejection (AR) and graft dysfunction (GD) in Koreans. METHODS Three hundred thirty-one patients who had kidney transplantation procedures were recruited. Transplantation outcomes were determined in terms of AR and GD criteria. We selected six single nucleotide polymorphisms (SNPs): rs1979855 (5' near gene), rs1049007 (Ser87Ser), rs235767 (intron), rs1005464 (intron), rs235768 (Arg190Ser), and rs3178250 (3; untranslated region). RESULTS Among the six SNPs tested, the rs235767, rs1005464, and rs3178250 SNPs were significantly associated with AR (P < .05). The rs1049007 and rs235768 SNPs also showed an association with GD (P < .05). CONCLUSIONS In conclusion, these results suggest that the BMP2 gene polymorphism may be related to the development of AR and GD in kidney transplant recipients.
