Abstract
Background To report a novel surgical technique for recurrent pupillary optic capture after flanged intraocular lens (IOL) fixation. Methods In this retrospective case series, we detail our use of two parallel 7-0 polypropylene sutures passed between the iris plane and the optic of scleral-fixated IOL to address pupillary optic capture. Flanges were created using ophthalmic cautery to secure it to the sclera without suture. Results Two eyes with pupillary optic capture underwent a sutureless surgical technique using 7-0 polypropylene flanges. No recurrences of pupillary optic capture were observed during the 1-year follow-up. Conclusion Our sutureless surgical technique using a 7-0 polypropylene flange was an effective, efficient, and less invasive approach for treating recurrent pupillary optic capture.

Abstract
This study aimed to analyze the duration and causes of persistent subretinal fluid (PSF) after scleral buckle (SB) surgery in patients with macula-involving rhegmatogenous retinal detachment (RRD). Sixty-one eyes of 61 patients with macula-involving RRD who underwent SB surgery between 2016 and 2022 were reviewed retrospectively. PSF was confirmed on optical coherence tomography. The PSF duration after surgery and the analysis of relevant ocular and systemic factors were conducted according to the PSF duration. The mean duration of PSF was 5.9 ± 4.6 months in all eyes and 8.1 ± 5.0 months in eyes not treated with external subretinal fluid (SRF) drainage, which was significantly longer than 4.5 ± 3.7 months in those subjected to external SRF drainage. The mean best-corrected visual acuity improved significantly 3 months after surgery. There were significant visual improvements in the external SRF drainage group compared to the non-drainage group during all follow-up periods. Longstanding shallow RRD was significantly associated with longer PSF duration after SB surgery. External SRF drainage during SB surgery can effectively reduce SRF, shorten the duration of PSF, and accelerate visual improvement.

Abstract
PURPOSE To identify risk factors for pupillary optic capture after sutureless flanged intraocular lens (IOL) fixation for IOL dislocation. METHODS This retrospective comparative study enrolled consecutive patients who underwent flanged IOL fixation using 25-gauge pars plana vitrectomy. One hundred twenty-six eyes (126 patients) were divided into two groups according to the presence or absence of pupillary optic capture. A swept-source anterior segment optical coherence tomography and a rotating Scheimpflug camera were used to analyze and compare surgical parameters, including axial length, anterior chamber depth, differences in scleral tunnel angle and length, and IOL tilt and decentration, between the two groups. RESULTS Compared with the nonpupillary optic capture group (106 eyes, 84.1%), the pupillary optic capture group (20 eyes, 15.9%) had larger differences in the nasal and temporal scleral tunnel angles and larger horizontal tilt (P < 0.05). Multivariate regression analysis demonstrated that these factors correlated with the occurrence of pupillary optic capture (P < 0.05). CONCLUSION To prevent pupillary optic capture after flanged IOL fixation, surgeons should avoid asymmetry in the angles of the nasal and temporal scleral tunnels, which causes horizontal IOL tilt and subsequent pupillary capture.

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
PURPOSE To evaluate plasma antiretinal autoantibody (ARA) profiling and diagnostic efficacy for autoimmune retinopathy (AIR). DESIGN A multicenter, diagnostic evaluation study. METHODS Forty-nine patients with a clinical diagnosis of AIR, disease controls including 20 patients with retinitis pigmentosa (RP), and 30 normal controls were included. Plasma samples from patients were analyzed for the presence of 6 ARAs, including recoverin, α-enolase, carbonic anhydrase II, heat shock protein 60, aldolase C, and cone-rod homeobox/cone-rod retinal dystrophy 2 using western blotting. RESULTS Autoantibody detection rates against cone-rod homeobox/cone-rod retinal dystrophy 2, heat shock protein 60, and aldolase C in AIR were 67.3%, 40.8%, and 42.9%, respectively, which were higher than those in RP and normal controls (P < .001, P < .001, and P = .007, respectively), but recoverin, α-enolase, and carbonic anhydrase II were not different from other control groups (P = .117, P = .774, and P = .467, respectively). Among ARAs, antirecoverin antibody was the most specific, as it was found in 3 (6.1%) patients with AIR and none of the control groups. As the number of detected ARAs increased, the probability of AIR increased (odds ratio: 1.913; P < .001; 95% confidence interval: 1.456-2.785). The positive number of ARAs was significantly higher when photoreceptor disruption was observed on optical coherence tomography, or severe dysfunction was observed in electroretinography (P = .022 and P = .029, respectively). CONCLUSIONS The profiles of ARAs in the AIR group were different from those in the RP and normal controls. The higher number of positive ARAs suggests a higher possibility of AIR diagnosis. ARAs should be used as adjunct tools for the clinical diagnosis of AIR.

Abstract
Background We evaluated the long-term efficacy and surgical outcomes of Ahmed glaucoma valve (AGV) implantation in patients with refractory glaucoma by glaucoma type. Methods In total, 135 eyes of 135 patients diagnosed with refractory glaucoma and underwent AGV implantation between 2002 and 2018 were reviewed retrospectively. The best-corrected visual acuity (BCVA), intraocular pressure (IOP), and number of antiglaucoma medications were investigated at baseline and follow-up. The cumulative probability of qualified success according to the glaucoma type was evaluated at 12, 24, 36, and 60 months postoperatively. Results The mean IOP of all patients was 35.7 ± 11.7 mmHg, which was significantly reduced 12.7 ± 7.0 mmHg at 1 week, 16.2 ± 7.5 mmHg at 2 weeks, 17.6 ± 6.8 mmHg at 1 month, 17.5 ± 6.4 mmHg at 3 months, 16.1 ± 6.0 mmHg at 6 months, 16.7 ± 8.0 mmHg at 12 months, 16.4 ± 6.6 mmHg at 24 months, 15.6 ± 5.0 mmHg at 36 months, and 15.6 ± 5.6 mmHg at 60 months after surgery (p < 0.001, respectively). The mean number of antiglaucoma medications was 3.7 ± 1.3, which significantly decreased to 0.4 ± 0.9 at 1 week, 0.3 ± 0.8 at 2 weeks, 0.7 ± 0.9 at 1 month, 1.1 ± 1.1 at 3 months, 1.4 ± 1.0 at 6 months, 1.5 ± 1.1 at 12 months, 1.6 ± 1.2 at 24 months, 1.7 ± 1.2 at 36 months, and 1.8 ± 1.3 at 60 months after surgery (p < 0.001, respectively). The mean BCVA significantly improved from postoperative 2 weeks. Although 71 (52.6%) eyes had postoperative complications, the cumulative probability of surgical success was 72.6% at 12 months, 66.7% at 24 months, and 63.7% at 36 and 60 months. According to the glaucoma type, the success rate of AGV implantation was more than 50% even after 60 months follow-up, except subgroup of neovascular glaucoma (NVG) due to retinal vein occlusion (RVO). Conclusions AGV implantation in patients with refractory glaucoma was, after long-term follow-up, successful overall. Therefore, AGV implantation can be an effective surgical option to reduce the IOP and number of antiglaucoma medications and to improve visual acuity for various glaucoma types.

Abstract
PurposeThis study evaluated the color contrast ratio (CCR) of the internal limiting membrane (ILM) using different color settings of digitally assisted vitreoretinal surgery (DAVS) with different indocyanine green (ICG) concentrations.sMethodsThis is a prospective comparative observational study. Consecutive patients that underwent 25G vitrectomy and ILM peeling using a standard operating microscope (SOM) (25 eyes), DAVS Ver. 1.1 (12 eyes), or DAVS Ver. 1.3 (13 eyes) were enrolled. The SOM and DAVS Ver. 1.1 groups used 0.075% ICG, and the DAVS Ver. 1.3 group used 0.025% ICG. In DAVS Ver. 1.1, macular CCR was compared between four different presets in the red, green, and blue channels: Default (Red (R) 100%, Green (G) 100%, and Blue (B) 100%); Preset 1 (R 20%, G 100%, B 100%); Preset 2 (R 80%, G 80%, B 100%), and Preset 3 (R 85%, G 100%, B 90%). In DAVS Ver. 1.3, macular CCR was evaluated using two different customized settings that modified the hue and saturation: Customized Setting 1 (R 86, G 100, B 100%, Hue +2°, Saturation 90%, Gamma 1.2) and Customized Setting 2 (R 90, G 100, B 100%, Hue +20°, Saturation 100%, Gamma 0.9). All patients underwent ophthalmologic examinations including BCVA at baseline and at 12 months.ResultsIn DAVS Ver. 1.1, macular CCR was highest in Preset 3 (P < 0.01). The CCR of Customized Setting 2 of DAVS Ver. 1.3 using 0.025% ICG did not differ from that of Preset 3 in DAVS Ver. 1.1 using 0.075% ICG. Furthermore, there was no significant difference in BCVA between the Customized Setting 2 of DAVS Ver. 1.3 with 0.025% ICG and the Preset 3 of DAVS Ver. 1.1 with 0.075% ICG groups at baseline and at 12 months (P > 0.05, respectively).ConclusionCustomized DAVS settings enabled surgeons to use a 3-fold lower ICG concentration in ILM peeling.

Abstract
Purpose: We report two cases of tacrolimus-related transplant-associated thrombotic microangiopathy (TA-TMA) retinopathy in leukemia patients who had undergone allogenic peripheral blood stem cell transplantation (PBSCT).Case summary: (Case 1) A 58-year-old woman with a history of PBSCT due to acute myelocytic leukemia and taking tacrolimus was referred to the ophthalmology clinic with visual disturbance. Her visual acuity (VA) was 0.4 in the right eye and 0.5 in the left eye. Multiple cotton wool spots and retinal hemorrhages were found in both eyes on fundus examination. Multiple capillary non-perfusions were seen on fluorescein angiography (FA). Tacrolimus-related TA-TMA retinopathy was suspected. Tacrolimus was discontinued and plasmapheresis was performed. After 3 months, neovascular glaucoma developed and her VA became “counting fingers” at 20 cm in both eyes. (Case 2) A 20-year-old man with a history of PBSCT due to acute lymphocytic leukemia and taking tacrolimus was referred to our clinic because of decreased VA in both eyes. His VA was 0.05 in the right eye and 0.025 in the left eye. Fundus and FA findings were the same as in Case 1, and the patient was suspected to have tacrolimus-related TA-TMA retinopathy. Tacrolimus was discontinued and plasmapheresis was performed. His VA was 0.2 in the right eye and 0.4 in the left eye at 1 month after treatment.Conclusions: It is necessary to consider TA-TMA retinopathy in leukemia patients taking calcineurin inhibitors, such as tacrolimus, who have decreased VA. Early diagnosis and treatment are important.

Abstract
Purpose: To investigate changes in intraocular pressure (IOP) and iridocorneal angle (ICA) configuration during smartphone use under room light. Methods: We included healthy adults aged 19-35 years with no ophthalmological abnormalities. All read text on a smartphone for 6 minutes under room light. IOP was measured via rebound tonometry at baseline and at 2, 4, and 6 minutes. ICA images were obtained via anterior segment optical coherence tomography after each IOP measurement. After 6 minutes, participants stopped reading text and rested for 2 minutes. IOP was then measured again. Results: The IOP significantly increased at 2, 4, and 6 minutes of reading compared to baseline (<i>p</i> < 0.001) but recovered to baseline after 2 minutes of rest (<i>p</i> = 1.000). The anterior chamber depth decreased significantly, and the anterior chamber angle width increased after 6 minutes of smartphone reading (both <i>p</i> < 0.05). Conclusions: IOP increased when reading smartphone text under room light but the ICA did not change. Prolonged smartphone reading is inappropriate for a patient at risk of glaucoma or glaucoma progression. Such patients should be cautioned.

Abstract
This report provides a detailed description of the methodology for ophthalmic examinations according to the Korea National Health and Nutrition Examination Survey (KNHANES) VII and VIII (from 2017 to 2021). The KNHANES is a nationwide survey which has been performed since 1998 in representatives of whole Korean population. During the KNHANES VII and VIII, in addition to the ophthalmic questionnaire, intraocular pressure measurement, visual field test, auto refractometry, axial length and optical coherence tomography measurements were included. This new survey will provide not only provide normative and pathologic ophthalmic data including intraocular pressure, refractive error, axial length, visual field and precise measurement of anterior segment, macula and optic nerve with optical coherence tomography, but also a more accurate diagnosis for major adult blindness diseases, including age-related macular degeneration, diabetic retinopathy, glaucoma, and other ocular diseases, for the national Korean population.

Abstract
Background To investigate the effect of intravitreal dexamethasone implant (DEX implant) on hard exudate (HE) accompanying diabetic macular edema (DME). Methods This study was a non-comparative non-randomized 1-year prospective interventional study. Patients with DME and HE were treated using DEX implant two or three times. Color fundus photography and optical coherence tomography (OCT) were performed at every visit. HE area was measured semi-automatically from the fundus photographs. Results Thirty-five patients completed the study. Eleven patients (31.4%) received two injections, while the remaining received three times. HE area (primary outcome) significantly decreased from 1.404±2.094 mm2 (baseline) to 0.212±0.592 mm2 (last visit), which was 24% of the baseline HE area (P<0.001). HE1500 (HE within 1500 μm from the fovea) area also decreased significantly from 0.382±0.467 mm2 to 0.066±0.126 mm2 (P<0.001). Furthermore, anaverage best corrected visual acuity (BCVA) improvement of 4.4 Early Treatment Diabetic Retinopathy Study (ETDRS) letters was observed (from 49.9±18.3 to 54.3±20.4 letters) (P= 0.008). Central macular thickness (CMT) decreased from 455.8±23.6 μm to 366.8±31.1 μm (P=0.009). Repetitive measurements for entire study duration was analyzed using generalized estimating equations (GEE), where BCVA was related to age, CMT, and HE1500 area in multivariate analyses. Conclusion DEX implant could reduce and suppress HE in DME for one year with two or three injections. And centrally located HE area (HE1500 area) is related to vision. Trial registration ClinicalTrials.gov, NCT02399657, Registered 26 March 2015.

Abstract
This study was performed to investigate the efficacy of the treat-and-extend regimen using aflibercept for treating diabetic macular oedema (DME). This prospective, multicentre, interventional, single-arm, 104-week clinical trial included 48 patients with DME visual impairment. The patients’ eyes received five consecutive intravitreal injections (2 mg aflibercept) every four weeks with two-week adjustments based on central subfield macular thickness (CSMT) changes. Injections were deferred when CSMT was stable. The number of injections, best-corrected visual acuity (BCVA), CSMT, and diabetic retinopathy severity scale scores were analysed. Compared to baseline, BCVA improved by + 9.1 letters at 52 weeks and was maintained with + 9.4-letter gain at 104 weeks (P < 0.001). Between baseline and 104 weeks, CSMT decreased from 489 to 298 μm (P < 0.001) and eyes with vision ≥ 20/40 increased from 17.4 to 43.5% (P = 0.007). The mean number of injections decreased from 8.5 in year one to 3.9 in year two. The injection interval was extended to ≥ 12 weeks in 56.5% of patients. The treat-and-extend regimen of aflibercept in DME showed 2-year efficacy comparable to that of fixed dosing regimens. The flexible dosing of this regimen reduced the number of injections in year two while maintaining efficacy.

Abstract
BACKGROUND The coronavirus disease 2019 (COVID-19) has reportedly affected almost 23 million people, with more than 800 thousand deaths globally. There have been a few reports on the ocular manifestations of COVID-19 patients in China but no reports in Korea. The present study aimed to examine ocular manifestations of COVID-19 patients in Korea. METHODS COVID-19 patients admitted from March 2020 to April 2020 at Keimyung University Dongsan Hospital and Keimyung University Daegu Dongsan Hospital were reviewed retrospectively for ocular manifestations. During the period of hospitalization, ocular symptoms as well as blood test results were noted and analyzed. Patients were then divided into the first-episode and relapsed group and ocular symptoms were analyzed in the groups. RESULTS A total of 103 patients were included in this study. Among them, 71patients were in the first-episode group and 32 patients in the relapsed group. No significant differences were determined in terms of positivity of ocular symptoms between the first-episode group (12 patients, 16.9%) and the relapsed group (10 patients, 31.3%, P > 0.05). Symptoms of positive upper respiratory infection and lower creatine phosphokinase were determined to be related to positive ocular symptoms. Conjunctival congestion was noted in seven patients. In the subgroup analysis, the conjunctival congestion-positive patients exhibited higher positivity of upper respiratory infection symptoms (100%) as compared with those in the negative group (40%, P = 0.017). CONCLUSION Positive upper respiratory infection symptoms and lower creatine phosphokinase were determined to be related to ocular symptoms in COVID-19 patients. Among these patients, positive upper respiratory infection symptoms were associated with conjunctival congestion.

Abstract
BACKGROUND The aim of this study was to evaluate the correlation between changes in the macular capillary network and macular edema (ME) recurrence with branch retinal vein occlusion (BRVO) using swept-source optical coherence tomography angiography (SS-OCTA). METHODS We reviewed the data for 43 patients with treatment-naïve ME associated with BRVO. Patients who received intravitreal bevacizumab injection were divided into two groups based on ME recurrence at 6 months after edema resolution. The perifoveal capillary morphology and the macular capillary vessel density (VD) were retrospectively analyzed using en face SS-OCTA after ME resolution. RESULTS The perifoveal capillary ring loss in the superficial capillary plexus (SCP) and deep capillary plexus (DCP) was more common in the ME recurrence group (n = 22) than in the no ME recurrence group (p = 0.047 and p = 0.002). Relative to the findings in the no ME recurrence groups, the destruction of the perifoveal capillary ring was more severe in the DCP (30.0° vs 87.3°, p = 0.001) than in the SCP (17.3° vs 69.5°, p = 0.006) in the ME recurrence group. The hemi-VD disparity between the affected and the unaffected areas in the SCP and DCP showed significant differences (p = 0.031 and p = 0.017), while macular VD showed no differences between the groups. CONCLUSIONS Destruction of the perifoveal capillary ring and hemi-VD disparity could be related to ME recurrence in BRVO. Therefore, these factors may be helpful in predicting ME recurrence.

Abstract
PURPOSE To compare surgical outcomes of sutureless flanged intraocular lens (IOL) fixation and conventional sutured scleral fixation (SF) for secondary IOL implantation in patients with IOL dislocation. METHODS This is a prospective, comparative cohort study on 103 consecutive patients (103 eyes) with IOL dislocation who underwent vitrectomy with IOL removal and sutured SF (53 eyes) or flanged IOL fixation (50 eyes). Operating time, best-corrected visual acuity (BCVA), refractive difference, IOL tilt and decentration using swept-source anterior segment OCT, and postoperative complications were measured for 12 months. RESULTS Operating time was significantly shorter for the flanged IOL fixation than for sutured SF (19.4 ± 4.6 vs. 48.9 ± 5.2 min, p < 0.001). BCVA in both groups improved at 1, 3, 6, and 12 months postoperatively (p < 0.05). BCVA in the 2 groups was similar during the 12 months of observation. The refractive difference, IOL tilt, IOL decentration, and incidence of postoperative complications were also not different in the 2 groups. CONCLUSION Sutured SF and flanged IOL fixation had similar visual outcomes and IOL stability in patients with IOL dislocation. However, the operating time for flanged IOL fixation was less than half that of the sutured SF. This technique is an efficient alternative for treating IOL dislocation.

Abstract
INTRODUCTION The purpose of this study was to report the one-year results of treatment of diabetic macular edema (DME) with aflibercept using a treat-and-extend regimen (TER). METHODS This was a prospective, multicenter, single-arm study planned for 2 years. The eyes received 5 consecutive intravitreal injections of 2 mg of aflibercept every 4 weeks, and the interval between injections was then adjusted by 2 weeks based on changes in the central subfield macular thickness (CSMT). If the CSMT was worse, stable, or better, the interval was shortened, extended, or maintained, respectively. The primary outcome measure was the change in best-corrected visual acuity (BCVA) from baseline to 104 weeks, and the secondary outcome was the change in BCVA from baseline to 52 weeks. RESULTS Of the 48 patients enrolled, 46 completed a 1-year visit. BCVA improved significantly by 9.1 letters (95% confidence interval: 5.3-13.0 letters) from 56.2 letters at baseline (p < 0.001), and CSMT decreased by -171.7 μm from 489.4 to 317.7 μm (p < 0.001). The proportion of eyes having 20/40 or better vision increased from 17.4 to 41.3%, and the proportion of eyes that gained ≥15 letters was 28.3%. The mean number of injections was 8.5 times for 52 weeks. Worsening of macular edema did not occur in 76.1% of eyes during the extension period, and the interval between injections was extended to 12 weeks in 73.9% of eyes at 52 weeks. CONCLUSIONS The TER showed 1-year efficacy comparable to that of the fixed dosing regimen of pivotal trials, and its flexible dosing would prevent overtreatment.

Methods This study is an observational case series. Five patients with acute drug-induced angle closure and transient myopia with ciliochoroidal effusion were examined by fluorescein angiography, indocyanine green angiography (ICGA) and ultrasound biomicroscopy (UBM). Results Five patients presented with bilateral visual loss and ocular pain after intake of topiramate, methazolamide, phendimetrazine tartrate or mefenamic acid. All patients showed elevated intraocular pressure (IOP) with shallow anterior chamber and myopic shift from − 0.5 to − 17.0 diopters (D). UBM showed ciliochoroidal effusions with diffuse thickening of the ciliary body in all cases. Rapid normalization of IOP and decrease of myopic shift occurred in all patients after discontinuing the suspected drugs. We classified the ICGA findings into 2 major signs (hypofluorescent dark spots, hyperfluorescent pinpoints) and 3 minor signs (diffuse choroidal hyperfluorescence, early hyperfluorescence of choroidal stromal vessel, and leakage and dilated retinal vessels). Conclusions The pathogenesis of acute drug-induced angle closure and transient myopia with ciliochoroidal effusion may be idiosyncratic reaction of uveal tissue to systemic drugs. Accumulation of extravascular fluid in the ciliochoroidal layer had a major role in the pathogenesis. ICGA could be a useful method to examine the pathophysiology of this condition by imaging of the choroidal layer.

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
PURPOSE This study aimed to evaluate the relationship between macular structural changes and visual prognosis after pars plana vitrectomy (PPV) for proliferative diabetic retinopathy. METHODS The study included 60 eyes that had undergone PPV. Macular optical coherence tomography (OCT) findings were classified into 5 groups preoperatively and 10 groups postoperatively. Best-corrected visual acuity (BCVA) were analyzed according to pre- and postoperative OCT. RESULTS From the preoperative OCT, normal fovea with/without traction, normal fovea with preretinal hemorrhage, and tractional retinal detachment involving fovea showed an increase in BCVA after PPV (all p < 0.05). Normal fovea, epiretinal membrane and macular thickening were common after surgery. Normal fovea, epiretinal membrane and edema outside of the fovea showed good visual prognosis (BCVA >20/50). Subfoveal fibrosis, macular hole, loss of foveal depression, and serous foveal detachment showed poor visual prognosis (BCVA <20/100). CONCLUSION Macular structural changes were various after PPV, and visual prognosis correlated with these changes.

Abstract
Purpose To evaluate the change of residual volume of eye drop after instillation in patients with 23-gauge microincision vitrectomy surgery (MIVS). Methods Patient who were treated 23-gauge MIVS from November 2014 to July 2015 were included. The residual volume was defined as the amount of remnant eye drop in patient's eyes after instillation, calculated as the difference between instillation volume and spilled volume of eye drop. Calculation of residual volume of eye drop was performed one day before surgery, and daily from postoperative day 1 to day 5. Results Forty consecutive patients were included. The residual volume of eye drop decreased from 30.3 ± 1.4 µL at baseline to 13.0 ± 1.5 µL at day 1, 18.3 ± 1.6 µL at day 2, 24.7 ± 1.5 µL at day 3, and 27.9 ± 1.4 µL in day 4, postoperatively (p < 0.001, respectively). The volume at postoperative day 5 was 29.4 ± 1.3 µL, but it was not different from the volume at baseline (p = 0.105). The change of residual volume was significantly correlated with postoperative chemosis (r = 0.672, p < 0.001) and effected by the number of quadrant with postoperative chemosis (p < 0.05). Conclusions This study shows that postoperative residual volume of eye drop after instillation decreased until postoperative day 4, and postoperative chemosis affects the change of residual volume. Thus, checking proper use of eye drops and teaching about instillation technique by physician is necessary for patients with 23-gauge MIVS.

Abstract
PURPOSE To investigate whether diabetic retinopathy phenotypes and albuminuria are associated with the overexpression of plasma semaphorin 3A (Sema3A). METHODS The study group with severe nonproliferative diabetic retinopathy (NPDR) or proliferative diabetic retinopathy (PDR), the diabetes without diabetic retinopathy group, and the control group without diabetes consisted of all consecutive patients who were scheduled to undergo intravitreal bevacizumab injection for treatment-naïve diabetic macular edema (DME) and senile cataract surgery, respectively. In all subjects, the plasma Sema3A levels before intravitreal bevacizumab injections or cataract surgery were measured by enzyme-linked immunosorbent assay. In the patients with DME, the capillary nonperfusion area (measured by fluorescein angiography), total macular volume (measured by spectral-domain optical coherence tomography), and the urine albumin-to-creatinine ratio were determined. RESULTS Severe NPDR (57 eyes) and PDR groups (51 eyes) both had significantly higher Sema3A levels than the control (58 eyes) and diabetes without diabetic retinopathy groups (54 eyes) (P < 0.001). Moreover, the PDR group had higher Sema3A levels than the severe NPDR group (P < 0.001). Plasma Sema3A levels correlated positively with the retinal nonperfusion area size (r = 0.844, P = 0.004), total macular volume (r = 0.765, P = 0.005), and the urine albumin-to-creatinine ratio (r = 0.752, P < 0.001). When DME patients were divided into normo-, micro-, and macroalbuminuria groups, the macroalbuminuria group had significantly higher plasma Sema3A levels than the microalbuminuria group or the normoalbuminuria group (P = 0.002 and P < 0.001, respectively). CONCLUSIONS The plasma Sema3A levels correlated significantly with the phenotypes of diabetic retinopathy and albuminuria. This suggests that Sema3A may be a potential biomarker for diabetic retinopathy and nephropathy.

Abstract
Retinal vein occlusion (RVO) is the second most common retinal vascular diseases and there are only a few Asian population-based studies with small samples. Hypertension is one of a modifiable risk factor of RVO, but no recent studies have shown the relationship between RVO and hypertension control status. We aimed to investigate the prevalence of RVO and its associated factors in an adult Korean population.A nationwide population-based, cross-sectional study. We enrolled 37,982 participants from the Korea National Health and Nutrition Examination Survey who were 19 years or older and who had undergone ophthalmologic exams from 2008 through 2012. All participants underwent a comprehensive ophthalmic examination, standardized ophthalmic and health interviews, and laboratory investigations. Digital fundus photographs were interpreted by retinal specialists who investigated for the presence of RVO. The prevalence of RVO was then estimated. RVO-associated factors were determined using step-wise logistic regression analyses. We also performed a subgroup analysis to evaluate the association between hypertension and RVO according to hypertension control status and antihypertensive medication use.Of those enrolled participants, 25,765 participants met our study criteria and were included in the analyses. The overall RVO prevalence (n = 205) was 0.6 ± 0.1% (0.6 ± 0.1% for branch RVO and <0.1% for central RVO), and no sex differences were observed. In multivariate logistic regression analyses after adjusting for all potential risk factors, we found the following factors to be significantly associated with RVO: old age (odds ratio (OR) = 1.72, 95% CI: 1.27-2.34), hypertension (OR = 2.56, 95% CI: 1.31-5.08), history of stroke (OR = 2.08, 95% CI: 1.01-4.45), and hypercholesterolemia (OR = 1.84, 95% CI: 1.01-3.35). In a subset of participants with hypertension, participants with uncontrolled hypertension (OR = 3.46, 95% CI: 1.72-6.94) and unmedicated hypertension (OR = 4.12, 95% CI: 2.01-8.46) were more significantly associated with RVO than participants without hypertension.RVO prevalence in Korea was moderate relative to that in the rest of the world, and RVO-associated factors were similar to those identified in other population-based studies. Well-controlled hypertension and antihypertensive medication showed inverse association with RVO.

Abstract
Purpose To investigate fixed-dosing aflibercept for treating polypoidal choroidal vasculopathy (PCV). Methods This phase IV, prospective, single-arm, interventional case series was conducted in eight centers. Forty treatment-naïve PCV patients were administered three monthly doses of intravitreal aflibercept (2.0 mg) and an injection every 2 months thereafter. Best-corrected visual acuity (BCVA) and central subfield macular thickness (CSMT) were measured at each visit. Fluorescein and indocyanine green angiography (ICGA) were performed at baseline, 3 and 12 months. The primary outcome measure was the proportion of patients who maintained BCVA (<15 letters loss) at 12 months. Changes in BCVA, macular appearance, and polypoidal lesion appearance were also examined. Results Thirty-five eyes (87.5 %) had maintained BCVA at 12 months. Average BCVA was significantly higher at 12 months (20/53, 64.2 letters) than at baseline (20/80, 55.1 letters, 9-letter gain; P < .001). Mean CSMT was significantly lower at 12 months (253.6 μm) than at baseline (365.2 μm, P < .001). The macula was dry in 32 (76.2 %), 27 (64.3 %), and 24 eyes (60.0 %) at 3, 6, and 12 months respectively. Fourteen eyes (33.3 %) had a fluid recurrence or increase at 6 months, and they had a significantly lower vision gain (P = .005) than other patients at 12 months. Complete polyp regression occurred in 26 eyes (66.7 %) at 12 months. Conclusions Fixed-dosing aflibercept showed favorable outcomes in PCV patients at 12 months. However, some patients had worse outcomes because of fluid recurrence during maintenance dosing, and these patients would require additional treatments.

Abstract
Purpose: The aim of this study was to evaluate the effect of intravitreal dexamethasone implant fragmentation on clinical outcomes in branch retinal vein occlusion (BRVO)-induced macular edema (ME). Methods: All consecutive patients receiving an intravitreal dexamethasone implant for BRVO-induced ME were divided into two groups depending on whether the implant was intact or had fragmented into two or more pieces on postoperative day 1. Best-corrected visual acuity (BCVA), intraocular pressure (IOP), and central subfield thickness (CST) on spectral-domain optical coherence tomography were measured for 6 months. Results: Among 68 patients, the implant was fragmented in 6 (8.8%) and intact in 62 (91.2%) eyes. The two groups did not differ in BCVA and CST at any time point (all p > 0.05). There was no difference in the ME recurrence rate, frequency of IOP elevation, and cataract progression between the two groups (all p > 0.05). Conclusion: Fragmentation seemed not to influence clinical outcomes of intravitreal dexamethasone implantation during 6 months or to alter the frequency of adverse events.

Abstract
PURPOSE To investigate whether macular edema (ME) due to branch retinal vein occlusion (BRVO) associates with retinal overexpression of angiopoietin-like 4 (ANGPTL4). The aqueous ANGPTL4 and vascular endothelial growth factor (VEGF) levels in patients with ME due to BRVO were measured, and the relationships between ANGPTL4 levels and the degree of retinal ischemia and edema were determined. METHODS The study and control groups consisted of all consecutive patients who were scheduled to undergo intravitreal bevacizumab injection for treatment-naïve BRVO with ME and senile cataract surgery, respectively. The study group was divided into the major BRVO and macular BRVO subgroups on the basis of the involved retinal area. The aqueous ANGPTL4 and VEGF levels were measured by enzyme-linked immunosorbent assay. In the patients with BRVO, capillary nonperfusion area by fluorescein angiography and central subfield macular thickness (CSMT) and total macular volume (TMV) by spectral-domain optical coherence tomography were determined. RESULTS Patients with ME due to BRVO (50 eyes) had higher aqueous ANGPTL4 and VEGF levels than the controls (61 eyes) (both P < 0.001). The major BRVO had higher ANGPTL4 and VEGF levels than the macular BRVO (both P < 0.001). The aqueous ANGPTL4 levels of all BRVO patients correlated positively with nonperfusion area (r = 0.901, P < 0.001), CSMT (r = 0.574, P < 0.001), and TMV (r = 0.453, P = 0.001), even after adjustment for VEGF levels. CONCLUSIONS The aqueous ANGPTL4 levels correlated significantly with phenotypes of BRVO with ME. This suggests that ANGPTL4 may be a candidate biomarker and treatment target in ischemia-induced retinopathies, including BRVO.

Abstract
The Korea National Health and Nutrition Examination Survey (KNHANES) is a national program designed to assess the health and nutritional status of the noninstitutionalized population of South Korea. The KNHANES was initiated in 1998 and has been conducted annually since 2007. Starting in the latter half of 2008, ophthalmologic examinations were included in the survey in order to investigate the prevalence and risk factors of common eye diseases such as visual impairment, refractive errors, strabismus, blepharoptosis, cataract, pterygium, diabetic retinopathy, age-related macular degeneration, glaucoma, dry eye disease, and color vision deficiency. The measurements included in the ophthalmic questionnaire and examination methods were modified in the KNHANES IV, V, and VI. In this article, we provide detailed information about the methodology of the ophthalmic examinations in KNHANES in order to aid in further investigations related to major eye diseases in South Korea.

Abstract
PURPOSE To evaluate the clinical and morphological characteristics as well as the surgical outcomes of tractional retinal elevation (TRE) in patients with proliferative diabetic retinopathy (PDR) by analyzing spectral-domain optical coherence tomography (SD-OCT). METHODS SD-OCT images of 26 eyes (24 patients) who visited our clinic because of TRE and PDR from August 2011 to August 2014 were reviewed. According to the presence or absence of tractional retinal detachment (TRD), patients were classified into group 1 (without TRD) or group 2 (with TRD), and the clinical characteristics and surgical outcomes of the two groups were compared. Furthermore, we categorized the SD-OCT morphological components into sponge, cystoid, saw tooth, bridging columnar, and TRD and compared the characteristics among patients who had different components. RESULTS Group 1 had 18 eyes and group 2 had eight eyes. No differences in age, best corrected visual acuity (BCVA), or spherical equivalent were observed between the two groups, but group 2 had longer axial length than that of group 1 (p = 0.02). A large variety of combined OCT findings was found in group 1 compared to that in group 2. TRD was the least combined form with the other morphological components. Although 92 % of eyes with the bridging columnar component had the cystoid component, TRD and tractional retinoschisis (TRS, bridging columnar morphology) were combined in only one eye. CONCLUSION Diabetic TRE may progress to TRD or TRS, which are mutually exclusive. They may progress to TRD in eyes with a long axial length, and cystoid macular edema seems to develop into TRS.

Abstract
OBJECTIVE To investigate the aqueous levels of angiopoietin-like 4 (ANGPTL4), semaphorin 3E (Sema3E), and vascular endothelial growth factor (VEGF) in patients with diabetic retinopathy and to ascertain their association with diabetic retinopathy phenotypes. DESIGN Prospective, nonrandomized, comparative case series. PARTICIPANTS Of all 104 consecutive patients (104 eyes) who had intravitreal anti-VEGF injections from April 2012 through April 2013 for diabetic macular edema (DME), 51 had severe nonproliferative diabetic retinopathy (NPDR) and 53 had proliferative diabetic retinopathy (PDR). The controls were 54 consecutive nondiabetic patients who had undergone cataract surgery (54 eyes) during the same period. METHODS The ANGPTL4, Sema3E, and VEGF levels in aqueous humor samples obtained before intravitreal injections were measured by enzyme-linked immunosorbent assay. Capillary nonperfusion area (NPA) was calculated from encircled angiography using the 7 standard field images described in the Early Treatment Diabetic Retinopathy Study protocol. Total macular volume (TMV) was measured by spectral-domain optical coherence tomography. MAIN OUTCOME MEASURES Aqueous ANGPTL4, Sema3E, and VEGF levels in severe NPDR, PDR, and control groups and their correlations with each other, NPA, and TMV. RESULTS The severe NPDR and PDR groups had higher aqueous levels of ANGPTL4 and VEGF than the control group (all P < 0.001). The PDR group had higher ANGPTL4 and VEGF levels than the severe NPDR group (both P < 0.001). The aqueous ANGPTL4 levels of all diabetic retinopathy patients correlated positively with NPA (r = 0.820, P = 0.003) and TMV (r = 0.824, P < 0.001). The control group had higher aqueous Sema3E levels than the NPDR and PDR groups (both P < 0.001). Aqueous Sema3E levels correlated negatively with VEGF levels in all subjects (r = -0.57, P = 0.025). CONCLUSIONS The ANGPTL4 may be a candidate target in DME treatment and a biomarker of ischemic-induced retinopathy, including diabetic retinopathy.

Abstract
Purpose To examine the association between female reproductive factors and age-related macular degeneration (AMD) in postmenopausal women. Design Nationwide population-based cross-sectional study. Methods A nationally representative dataset acquired from the 2010–2012 Korea National Health and Nutrition Examination Survey was analyzed. The dataset involved information for 4,377 postmenopausal women aged ≥50 years with a fundus photograph evaluable for AMD in either eye. All participants were interviewed using standardized questionnaires to determine reproductive factors including menstruation, pregnancy, parity, lactation, and hormonal use. The association between reproductive factors and each type of AMD was investigated. Results The mean age of the study participants was 63.1±0.2 years. Mean ages at menarche and menopause were 16.1±0.0 and 49.2±0.1 years, respectively. The overall prevalence rates of early and late AMD were 11.2% (95% confidence interval [CI], 10.1–12.5) and 0.8% (95% CI, 0.5–1.2), respectively. When adjusted for age, neither smoking nor alcohol use was associated with the presence of any AMD or late AMD. Multivariate logistic regression analysis revealed age (OR, 1.12 per 1 year), duration of lactation (OR, 0.91 per 6 months), and duration of use of oral contraceptive pills (OCP) (OR, 1.10 per 6 months) as associated factors for late AMD. The other variables did not yield a significant correlation with the risk of any AMD or late AMD. Conclusion After controlling for confounders, a longer duration of lactation appeared to protect against the development of late AMD. A longer duration of OCP use was associated with a higher risk of late AMD.

Abstract
PURPOSE We examined the epidemiological association between systemic diseases and age-related macular degeneration (AMD) in the general Korean population. METHODS This cross-sectional study involved nationally representative data obtained from the 2008 to 2011 Korea National Health and Nutrition Examination Surveys. A total of 14,352 subjects aged ≥40 years participated in standardized health interviews regarding physician-diagnosis of several systemic diseases as well as physical examinations, including fundus photography for the evaluation of AMD. RESULTS The overall prevalence rates of early, late, and any AMD were 6.0%, 0.6%, and 6.6%, respectively. In univariate logistic regression analyses adjusted for age and sex as well as smoking in late AMD, any AMD and late AMD were less prevalent among diabetic patients and more prevalent in participants with a history of liver cancer. A history of liver cirrhosis was associated with a higher prevalence of any AMD. In the final multivariate model, the associated factors for any AMD included age (odds ratio [OR], 1.09), the presence of diabetes mellitus (DM; OR, 0.74), and a history of liver cancer (OR, 4.32). Factors associated with late AMD included age (OR, 1.09), ever-smoking history (OR, 2.45), the presence of DM (OR, 0.22), and a history of liver cancer (OR, 12.51). The presence of diabetic retinopathy was associated with a lower prevalence of any AMD (OR, 0.35). CONCLUSIONS When adjusted for confounders, any AMD and late AMD were less prevalent in diabetic patients. In contrast, a history of liver cancer was associated with a higher prevalence of any AMD and late AMD.
