RESUMEN
Purpose: Pathogenic variants in North Carolina macular dystrophy (NCMD) have rarely been reported in the East Asian population. Herein, we reported novel variants of NCMD in 2 Korean families. Methods: The regions associated with NCMD were analyzed with genome sequencing, and variants were filtered based on the minor allele frequency (0.5%) and heterozygosity. Non-coding variants were functionally annotated using multiple computational tools. Results: We identified two rare novel variants, chr6:g.99,598,914T>C (hg38; V17) and chr6:g.99,598,926G>A (hg38; V18) upstream of PRDM13 in families A and B, respectively. In Family 1, Grade 2 NCMD and a best-corrected visual acuity of 20/25 and 20/200 in the right and left eyes, respectively, were observed. In Family B, all affected individuals had Grade 1 NCMD with characteristic confluent drusen at the fovea and a best-corrected visual acuity of 20/20 in both eyes. These two variants are 10-22 bp downstream of the reported V10 variant within the DNase1 hypersensitivity site. This site is associated with progressive bifocal chorioretinal atrophy and congenital posterior polar chorioretinal hypertrophy and lies in the putative enhancer site of PRDM13. Conclusion: We identified two novel NCMD variants in the Korean population and further validated the regulatory role of the DNase1 hypersensitivity site upstream of PRDM13.

PURPOSE: To determine the association between pentosan polysulfate (PPS) use and the subsequent development of maculopathy in Asian population. DESIGN: A nationwide population-based retrospective cohort study using the Health Insurance Review and Assessment Service database. PARTICIPANTS: 103,553 individuals in the PPS user group and 205,792 individuals in the PPS non-user group, all newly diagnosed with cystitis between 2009 and 2020. METHODS: The association between PPS use and maculopathy was evaluated using a time dependent Cox proportional hazard model. Additionally, two sensitivity analyses were conducted by defining PPS users as individuals with an observation period over 6 months from the initial prescription or those with cumulative dose exceeding 9 g, employing the same analysis. MAIN OUTCOME MEASURES: The outcome measures included the hazard ratios (HR) representing the association between PPS use and maculopathy. RESULTS: PPS use was associated with an increased risk of subsequent maculopathy in univariate (HR, 1.7; 95% confidence intervals [CI], 1.66-1.75) and multivariate analysis (HR, 1.34; 95% CI, 1.31-1.38). These results were also confirmed in two sensitivity analyses. The mean cumulative dose of PPS for the cohort was 37.2 ± 76.7 g. CONCLUSIONS: In this nationwide cohort study involving an Asian population, individuals with cystitis using PPS exhibit an increased risk of developing subsequent maculopathy.
RESUMEN
PURPOSE: This study aimed to analyze the genetic results of inherited retinal diseases (IRDs) and evaluate the diagnostic usefulness of whole genome sequencing (WGS) in the Korean National Project of Bio Big Data. METHODS: As part of the Korean National Project of Bio Big Data, WGS was performed on 32 individuals with IRDs with no identified pathogenic variants through whole or targeted exome sequencing. RESULTS: Individuals with retinitis pigmentosa (n = 23), cone dystrophy (n = 2), cone-rod dystrophy (n = 2), familial exudative vitreoretinopathy (n = 2), pigmented paravenous chorioretinal atrophy (n = 1), North Carolina macular dystrophy (n = 1), and bull's-eye macular dystrophy (n = 1) were included. WGS revealed genetic mutations in the IQCB1, PRPF31, USH2A, and GUCY2D genes in five cases (15.6%). Two large structural variations and an intronic variant were newly detected in three cases. Two individuals had biallelic missense mutations that were not identified in previous exome sequencing. CONCLUSION: With WGS, the causative variants in 15.6% of unsolved IRDs from the Korean National Project of Bio Big Data were identified. Further research with a larger cohort might unveil the diagnostic usefulness of WGS in IRDs and other diseases.

PURPOSE: This study aimed to evaluate changes in intraocular pressure following intravitreal dexamethasone implant injection, specifically in patients undergoing glaucoma filtration surgery. METHODS: The degree of increase in intraocular pressure was compared retrospectively among three groups. Group 1 comprised patients who underwent prior glaucoma filtration surgery (54 eyes). Group 2 included patients with or suspected glaucoma without such surgical history (20 eyes). Group 3 included patients without glaucoma (33 eyes). Pressure measurements were taken before the injection and at 1, 2, 3, and 6 months post-injection. A subgroup analysis was performed for pressure > 35 mmHg, > 30 mmHg, > 25 mmHg, and a difference > 10 mmHg between the peak and baseline pressure. RESULTS: Group 1 consistently displayed lower pressures compared with Group 2, with significant difference at both 1- and 6-month post-injections (15.09 mmHg vs. 18.10 mmHg, P = 0.042 and 13.91 mg vs. 17.25 mmHg, P = 0.040). The proportion of patients in Group 1 and Group 3 with pressures > 25 mmHg, > 30 mmHg, and a difference > 10 mmHg did not significantly differ (15.6% vs. 9.5%, P = 0.231; 3.1% vs. 2.3%, P = 0.867; and 17.1% vs. 7.1%, P = 0.231). Notably, Group 2 exhibited a significantly higher proportion within each category (> 25 mmHg, 24.0%; > 30 mmHg, 20.0%; > 10 mmHg difference, 28.0%). CONCLUSION: Intravitreal dexamethasone implant did not increase the risk of elevated intraocular pressure in patients with a history of glaucoma filtration surgery compared with patients with suspected glaucoma; the risk was similar to those without glaucoma.
RESUMEN
PURPOSE: To investigate the efficacy, safety, and indications for additional pneumatic retinopexy (PR) in patients with persistent retinal detachment after scleral buckling. METHODS: This retrospective study included patients who underwent additional PR after scleral buckling for primary rhegmatogenous retinal detachment (n = 78). We defined "inadequate buckle" as retinal detachment persistence because of low buckle height despite accurate buckle placement and "buckle misplacement" as an uncovered tear because of incorrect buckle placement. RESULTS: The anatomical success rate after additional PR was 52.6%. Development of proliferative vitreoretinopathy Grade B (hazard ratio, 5.73; P < 0.001) and inferior retinal tears (hazard ratio, 2.12; P = 0.040) were significant risk factors for anatomical failure. The most common cause of anatomical failure was proliferative vitreoretinopathy (19 of 37; 51.4%), and epiretinal membrane formation was a common complication after additional PR (22 of 78; 28.2%). The anatomical success rate with additional PR was significantly higher in the inadequate buckle group than in the misplacement group (8 of 9 [88.9%] vs. 1228 [42.9%]; P = 0.023). CONCLUSION: Development of proliferative vitreoretinopathy Grade B and inferior retinal tears were significantly associated with anatomical failure after additional PR. Additional PR may benefit patients with superior retinal tears or low buckle height and those without proliferative vitreoretinopathy.

INTRODUCTION: The objective of this study was to investigate the clinical characteristics and genetic spectrum of adult-onset cone/cone-rod dystrophy (AOCD/AOCRD) in Korean individuals. METHODS: This is a single-center, retrospective cross-sectional study. We analyzed 22 individuals with genetically confirmed cone dystrophy, with symptoms beginning after 30 years of age. All patients underwent comprehensive ophthalmic and electrophysiological examinations. Exome sequencing of 296 genes associated with inherited retinal disease was performed. The clinical features of patients with AOCD/AOCRD and the causative genes and variants detected by exome sequencing were analyzed. RESULTS: The median age at the first visit was 52 years (range, 31-76 years), and the most common initial symptom was reduced visual acuity. In most cases, fundus photography showed a bull's eye pattern with foveal sparing, consistent with perifoveal photoreceptor loss on optical coherence tomography. We identified disease-causing variants in six genes: RP1, CRX, CDHR1, PROM1, CRB1, and GUCY2D. Pathogenic variants in RP1, CRX, and CDHR1 were identified in 77% of the AOCD/AOCRD cases, including p.Cys1399LeufsTer5, p.Arg1933Ter, and p.Ile2061SerfsTer12 in RP1; p.Ter300GlnextTer118 in CRX; and p.Glu201Lys in CDHR1. No characteristic imaging differences were observed for any of the causative genes. Most of the RP1-related AOCD/AOCRD cases showed a decreased amplitude only in the photopic electroretinogram (ERG), whereas CRX-related AOCD/AOCRD cases showed a slightly decreased amplitude in both the scotopic and photopic ERGs. CONCLUSION: In case of visual impairment with bull's eye pattern of RPE atrophy recognized after the middle age, a comprehensive ophthalmic examination and genetic test should be considered, with the possibility of AOCD/AOCRD in East Asians.

BACKGROUND: The prevalence of diabetes is increasing globally, highlighting the importance of preventive healthcare. This study aimed to identify the diabetic retinopathy (DR) screening rates and risk factors linked to DR screening nonadherence in the Korean population through a nationally representative sample survey. METHODS: Among the Korea National Health and Nutrition Examination Survey database from 2016 to 2021, participants aged ≥ 40 years with diabetes were included. The weighted estimate for nonadherence to DR screening within a year was calculated. Risk factor analyses were conducted using univariate and multivariate logistic regression. RESULTS: Among the 3,717 participants, 1,109 (29.5%) underwent DR screening within the past year, and this national estimate exhibited no statistically significant difference from 2016 to 2021 (P = 0.809). Nonadherence to annual DR screening was associated with residing in rural areas, age ≥ 80 years, low educational level, self-reported good health, absence of ocular disease, current smoking, lack of exercise and dietary diabetes treatment, and no activity limitation (all P < 0.05). CONCLUSION: The recent DR screening rate in Korea was relatively low. Factors associated with apathy and complacency towards personal health were associated with the nonadherence to DR screening. Educational interventions have the potential to enhance the annual screening rate for diabetic patients.

X-linked juvenile retinoschisis (XLRS) is a hereditary retinal degeneration affecting young males caused by mutations in the retinoschisin (RS1) gene. We generated human induced pluripotent stem cells (hiPSCs) from XLRS patients and established three-dimensional retinal organoids (ROs) for disease investigation. This disease model recapitulates the characteristics of XLRS, exhibiting defects in RS1 protein production and photoreceptor cell development. XLRS ROs also revealed dysregulation of Na/K-ATPase due to RS1 deficiency and increased ERK signaling pathway activity. Transcriptomic analyses of XLRS ROs showed decreased expression of retinal cells, particularly photoreceptor cells. Furthermore, relevant recovery of the XLRS phenotype was observed when co-cultured with control ROs derived from healthy subject during the early stages of differentiation. In conclusion, our in vitro XLRS RO model presents a valuable tool for elucidating the pathophysiological mechanisms underlying XLRS, offering insights into disease progression. Additionally, this model serves as a robust platform for the development and optimization of targeted therapeutic strategies, potentially improving treatment outcomes for patients with XLRS.

Background: Concerns of intraocular inflammation associated with intravitreal administration of anti-VEGF drugs have been risen and the exact mechanism is not yet elucidated. Objective: To explore the relationship between immunogenicity and intraocular inflammation in intravitreal anti-VEGF drugs. Methods: This review examines the immunogenicity of individual intravitreal anti-VEGF drugs and their potential link to intraocular inflammation. Results: We suggest that the main cause of intraocular inflammation is the presence of pre-existing and treatment-induced antidrug antibodies, along with considerations related to the molecular structure, which includes the drug's format and size. Conclusions: Researchers and clinicians involved in the advancement of new anti-VEGF drugs should take into consideration the factors related to intraocular inflammation that have been discussed.
RESUMEN
OBJECTIVE: To compare the risk of blindness and vision-threatening ocular comorbidities in patients with Behçet's disease (BD) vs the general population. METHODS: Using 2002-2017 Korea National Health Insurance Service database, we did a population-based cohort study comparing newly diagnosed BD patients and age- and sex-matched non-BD controls at a 1:5 ratio. The primary outcome was blindness, defined as a best-corrected visual acuity of ≤20/500 in the better-seeing eye. Secondary outcomes were vision-threatening ocular comorbidities (cataract, glaucoma and retinal disorders) that require surgical interventions and incident uveitis. Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% CIs. We performed subgroup analyses by sex and BD diagnosis age. RESULTS: We included 31 228 BD patients and 156 140 controls. During a follow-up of 9.39 years, the incidence rate of blindness per 1000 person-years was 0.24 in BD and 0.02 in controls with an HR of 10.73 (95% CI 7.10, 16.22). The HR for secondary outcomes was 2.06 (95% CI 1.98, 2.15) for cataract surgery, 5.43 (4.57, 6.45) for glaucoma surgery and 2.71 (2.39, 3.07) for retinal surgery. The HR of incident uveitis was 6.19 (95% CI 5.83, 6.58). Males suffered a disproportionately higher risk of blindness than females due to greater severity rather than a lower incidence of uveitis. The risk of uveitis and blindness decreased as BD diagnosis age increased. CONCLUSIONS: In this large population-based cohort study, BD patients compared with the general population have a 10.73-fold risk of blindness in 10 years and also a substantially higher risk of diverse ocular comorbidities that pose potential threats to vision.

PURPOSE: To characterize the genotype and phenotype of a patient with CAPN5-related neovascular inflammatory vitreoretinopathy (NIV) who have undergone surgery for macular holes. METHODS: We observed a patient presenting with retinitis pigmentosa and posterior uveitis who later developed vitreoretinal macular traction and a macular hole. Genetic testing was performed using a targeted gene panel. Fundus photography and spectral-domain optical coherence tomography were also performed. RESULTS: In a targeted gene panel, a monoallelic pathogenic variant, c.750G > T, p.Lys250Asn, in the CAPN5 gene was identified, and CAPN5-NIV was diagnosed. At the first visit, peripheral retinal degeneration and mild posterior uveitis were observed. At that time, neovascularization, epiretinal or fibrous membranes were not observed. After 5 years, vitreomacular traction developed and progressed to a full-thickness macular hole in both eyes. After pars plana vitrectomy, the macular hole was successfully closed without aggravation of uveitis. CONCLUSION: In this case, a pathogenic variant of CAPN5 lead to a distinct phenotype of retinitis pigmentosa, posterior uveitis, vitreomacular traction, and macular hole without typical inflammatory neovascularization or tractional membranes. Therefore, the clinical variability of CAPN5-NIV and genetic diagnosis should be considered in cases of atypical retinitis pigmentosa with bilateral macular hole.

PURPOSE: This study aims to investigate the association between incident central retinal artery occlusion (CRAO) and the subsequent development of cancer. METHODS: We included incident CRAO patients from the 2002-2013 National Health Insurance Service database in South Korea. For the patient cohort, we included patients diagnosed with CRAO from the database, and excluded patients having CRAO or any cancer history during the first 2-year washout period (2002-2003). Then, we defined their 1:4 propensity-score matched non-CRAO subjects as controls, all of whom also had no history of cancer during the washout period. Time-varying covariate Cox regression models were conducted to determine the association of CRAO with cancer. Kaplan-Meier curves with log-rank test were also analyzed. RESULTS: A total of 9712 patients with CRAO and 38,848 controls were included in the study. CRAO was associated with an increased risk of subsequent cancer (hazard ratio = 1.27; 95% confidence interval, 1.19-1.35). The incidence rate of overall cancer during the study period was 29.12 per 1000 person-years in the CRAO group and 22.77 per 1000 person-years in the control group. Incidence probability of overall cancer was significantly higher among CRAO patients than controls (P < 0.001, log-rank test). CONCLUSION: The risk of cancer occurrence was increased in patients with CRAO. The results supported that CRAO could be attributed to one of the consequences of arterial thrombosis in cancer patients.

PURPOSE: To determine whether 14 inflammation-, angiogenesis-, and adhesion-related proteins in cord blood (CB), alone or in combination with conventional perinatal factors, could predict retinopathy of prematurity (ROP) in preterm infants. METHODS: Data from 111 preterm infants (born at ≤ 32.0 weeks) were retrospectively reviewed. The levels of endoglin, E-selectin, HSP70, IGFBP-3/4, LBP, lipocaline-2, M-CSFR, MIP-1α, pentraxin 3, P-selectin, TGFBI, TGF-ß1, and TNFR2 were assessed in stored CB samples collected at birth using ELISA kits. The primary endpoints included severe ROP (≥ stage 3) and type 1 ROP requiring treatment. RESULTS: ROP was diagnosed in 29 infants (26.1%), among whom 14 (12.6%) had severe ROP and seven (6.3%) had type 1 ROP. Multivariate logistic regression showed that decreased CB TGFBI levels were significantly associated with severe ROP and type 1 ROP after adjusting for gestational age at birth. Stepwise regression analysis allowed to design prediction models with good accuracy, which comprised low CB TGFBI levels and low birth weight (BW) as predictors for severe ROP (area under the curve [AUC] = 0.888), and low CB endoglin levels and low BW as predictors for type 1 ROP (AUC = 0.950). None of the other CB proteins evaluated were found to be associated with severe ROP or type 1 ROP. CONCLUSIONS: Low CB TGFBI levels are associated with severe ROP and type 1 ROP, independently of gestational age. Moreover, combined predictive models based on CB TGFBI and endoglin levels, along with BW data, may act as good indicators at birth for the neonatal risk of ROP progression.

BACKGROUND: Evidence for the association between psoriasis and uveitis according to the severity of psoriasis including psoriatic arthritis (PsA) and type of uveitis is lacking, and there are no data on the frequency or timing of recurrence of uveitis in patients with psoriasis. OBJECTIVES: We aimed to evaluate the risk of first occurrence and recurrence of uveitis in patients with psoriasis in the Korean population. We further evaluated the risk of uveitis according to the severity of psoriasis, comorbidity of PsA and location of uveitis. METHODS: In a nationwide retrospective cohort study, we compared 317,940 adult patients who had psoriasis with 635,880 matched controls. Incidence rates (IRs) and estimated IR ratios of the first occurrence and recurrence of uveitis were calculated using survival analysis and Poisson regression, respectively. RESULTS: The rate of uveitis incidence and uveitis recurrence in patients with psoriasis was 1.18 and 2.31 per 1000 person-years, respectively. Compared to the controls, the IR ratios of development and recurrence of uveitis in patients with psoriasis were 1.14 (95% CI 1.08, 1.2) and 1.16 (95% CI 1.12, 1.21), respectively. The recurrence rate of uveitis was highest within 3 years after the onset of psoriasis. The corresponding IR ratios for uveitis recurrence in patients with mild psoriasis, severe psoriasis and PsA were 1.11 (1.06, 1.16), 1.24 (1.16, 1.33) and 1.49 (1.31, 1.7), respectively. Patients with psoriasis had an increased risk of recurrence of anterior uveitis, and patients with both psoriasis and PsA had an increased risk of recurrence of both anterior-uveitis and panuveitis. CONCLUSIONS: Patients with psoriasis had a higher risk of both development and recurrence of uveitis, especially with severe psoriasis and PsA. The timing of uveitis recurrence was related to the onset of psoriasis, and patients who had psoriasis with PsA had an increased risk of vision-threatening panuveitis.

INTRODUCTION: The aim of this study was to report surgical outcomes and risk factors for primary surgical failure following rhegmatogenous retinal detachment (RRD) repair. METHODS: In this retrospective cohort study, RRD patients who underwent primary surgery at a tertiary center between January 1, 2006, and December 31, 2020, were enrolled. Surgical failure was defined as reoperation within 60 days postoperatively due to retinal re-detachment and putative risk factors for surgical failure were analyzed. RESULTS: Of 2,383 eyes (2,335 patients), 1,342 (56.3%) underwent vitrectomy and 1,041 (43.7%) underwent scleral buckling. The surgical failure rate was 9.1% overall, and 6.0% and 13.1% for the vitrectomy and scleral buckling groups, respectively. In the multivariate logistic regression analysis, surgical failure was associated with surgical experience (first-year fellow vs. senior professor) (odds ratio [OR]: 1.66; p = 0.018), scleral buckling (OR: 2.33; p < 0.001), and longer axial length (AL; ≥26.5 mm) (OR: 1.49; p = 0.017). In each surgical approach, age <40 years (OR: 2.11; p = 0.029) in the vitrectomy group and age >40 years (OR, 1.84; p = 0.004), male sex (OR: 1.65; p = 0.015), and first-year fellows compared to senior professors (OR: 1.95; p = 0.013) in the scleral buckling group were associated with surgical failure. Lens status were not associated with the surgical failure rate. CONCLUSION: In this large retrospective study using data from Korea, vitrectomy was superior to scleral buckling in terms of primary anatomical outcomes in the management of RRD. First-year fellows were a risk factor for surgical failure, especially for scleral buckling. Longer AL was a significant parameter for predicting the success rates.

INTRODUCTION: The aim of the study was to determine the short-term real-world safety and efficacy of intravitreal brolucizumab injections in Korean patients with neovascular age-related macular degeneration (nAMD). METHODS: This multicenter retrospective study involved 294 eyes (treatment naïve 20 eye [6.8%] and nontreatment naïve 274 eyes [93.2%]) of 290 patients from 13 hospitals or retinal centers in South Korea. Patients with nAMD who received brolucizumab injection(s) between April 1 and November 30, 2021, with a follow-up ≥1 month, were included. Primary outcomes were safety, incidence of intraocular inflammation (IOI), and potential risk factors. The secondary outcome was efficacy, i.e., change in best-corrected visual acuity (BCVA) and optical coherence tomography-measured macular thickness and retinal fluid. RESULTS: The mean age was 71.63 ± 8.66. The follow-up period was 2.38 ± 0.79 months. The mean number of brolucizumab injections during the follow-up was 1.52 ± 0.58. The overall incidence of IOI was 13.9% (n = 41 eyes). Most IOI cases were of anterior uveitis (8.8%, 26 eyes), followed by retinal vasculitis (2.4%, seven eyes) and occlusive retinal vasculitis (0.3%, one eye). Most eyes showed IOI resolution (n = 40, 97.5%) and BCVA restoration (n = 39, 95.1%) with or without corticosteroid treatment during the follow-up. Age, sex, IOI history, or other anti-vascular endothelial growth factor injection histories were not associated with the occurrence of IOI. However, only thin subfoveal choroidal thickness (SFCT) was associated with the occurrence of IOI (odds ratio = 0.995, p = 0.020). BCVA at 1 month improved from baseline (baseline 0.518 ± 0.356 vs. 1 month 0.503 ± 0.383, p = 0.023), but the improvement was not maintained. Anatomical improvement was significant after 3 months. CONCLUSION: In Korean patients with nAMD, the incidence of IOI following brolucizumab injections was 13.9%. IOI was well-controlled with or without steroid treatment. Most IOI eyes (95.1%) were restored to the level of vision before. IOI occurrence and occlusive vasculitis was rare. In the short term, brolucizumab injection effectively improved vision at 1 month and dried retinal fluid for 3 months.

PURPOSE: To evaluate the necessity and safety of primary posterior capsulotomy during phaco-vitrectomy for idiopathic epiretinal membrane (ERM). SETTING: Seoul National University Bundang Hospital, Seongnam, Korea. DESIGN: Retrospective consecutive cohort analysis. METHODS: This study enrolled 219 patients (228 eyes) who underwent combined 25-gauge phaco-vitrectomy for idiopathic ERM and cataract, divided into capsulotomy (-) group (152 eyes, 144 patients) and capsulotomy (+) group (76 eyes, 75 patients). The main outcomes were rate of posterior capsular opacity (PCO) occurrence and postoperative complications. Ophthalmic examinations were performed at baseline, 1, 3, 6, and 12 months postoperatively. RESULTS: PCO only occurred in capsulotomy (-) group (20 eyes, 13.2%), with mean onset of 10.59 months. Visually-significant PCO that needed Nd:YAG posterior capsulotomy was present in 9 eyes (45.0% of PCO eyes). The rate of cystoid macular edema (CME) was higher in capsulotomy (+) group (6.6% vs. 15.8%, p = 0.026) with longer duration (1.50 vs. 3.36 months, p = 0.019). Female sex and posterior capsulotomy were significant risk factors for CME occurrence (p < 0.05). CONCLUSION: Primary posterior capsulotomy during phaco-vitrectomy for idiopathic ERM obviated the need for Nd:YAG posterior capsulotomy, but visually-significant PCO that needed Nd:YAG laser was not common. Considering the low rate of visually-significant PCO and high rate of postoperative CME, routine posterior capsulotomy during phaco-vitrectomy may not be necessary for preventing PCO in ERM.

BACKGROUND: To compare the efficacy of intraoperative localized and 360-degree laser photocoagulation in 23-gauge limited pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment (RRD). METHODS: This retrospective, comparative, consecutive, interventional study included 155 eyes of 155 patients who underwent primary repair of RRD utilizing 23-gauge PPV with at least six months of follow up. Medical records were retrospectively reviewed, and the corresponding demographic data, preoperative ophthalmic features, surgical management, and postoperative course were recorded. Main outcome measures included single surgery anatomical success, pre- and post-operative visual acuity, and complications. RESULTS: Eighty-three patients (group A) received localized laser photocoagulation in PPV, while the remaining 72 patients (group B) received underwent circumferential 360-degree laser photocoagulation in PPV. Two skilled-surgeons performed all the surgeries, and 23-gauge PPV instrumentation, a wide-angle viewing system, endolaser photocoagulation, and gas tamponade were used in each case. No significant difference was identified in baseline characteristics. The single surgery anatomical success rate was 96.4 % in group A, and 95.8 % in group B, showing no significant difference (p = 1.00). Primary anatomical failure was caused by re-detachment due to break in 2 eyes in each group (no new break 1 eye, new break 1eye in group A, 2 eyes with no new break in group B), and proliferative vitreoretinopathy in 1 eye in each group. Other complications were epiretinal membrane in 7 eyes (3 in group A, 4 in group B), and macular hole in 1 eye in group B. There were no differences in pre- and post-operative best-corrected visual acuity (BCVA) as well as BCVA improvement (p=0.144, p=0.866 and p=0.263, respectively). CONCLUSION: Localized laser photocoagulation showed no difference in anatomic and visual outcome in RRD patients, when compared with 360-degree laser photocoagulation in limited PPV. Routine circumferential 360-degree laser photocoagulation may not be necessary in vitrectomy surgery for primary rhegmatogenous retinal detachment without severe PVR.

BACKGROUND: Ophthalmic artery occlusion (OAO) and retinal artery occlusion (RAO) after facial filler injection have become increasingly significant due to the growth in cosmetic injection procedures for aesthetic purposes. OBJECTIVES: The aim of this study was to analyze the long-term visual outcomes and complications of cosmetic facial filler-related OAO and RAO. METHODS: This single-center, retrospective case series included 17 eyes of 16 filler-related OAO or RAO patients with a follow-up period of 1 year or longer. Main outcome measures were best-corrected visual acuity (BCVA) and long-term complications. RESULTS: The mean [standard deviation] age at diagnosis was 31.7â [9.7] years; all the patients were female. The mean follow-up period was 5.4â [2.4] years. The mean BCVA was 2.34 and 2.41 logMAR at the initial and final visits, respectively, which indicates sustained long-term visual impairment. Ocular complications included retinal atrophy and degeneration (100.0%), optic atrophy and blindess (no light perception) (82.4%), strabismus (80.0%), retinal fibrous membrane (68.8%), posterior synechiae (35.3%), neovascularization (29.4%), iris atrophy and cataract (23.5%), corneal opacity and phthisis bulbi (17.6%), visual field defect and iris defect (11.8%), ophthalmoplegia (7.7%), and pupillary block (5.9%). Extraocular complications of brain infarction and depression were found in 25.0%, whereas skin necrosis was found in 13.3% of patients. CONCLUSIONS: Facial filler-related OAO or RAO resulted in long-term poor visual outcome, and most of the patients experienced irreversible visual impairment with no light perception despite various treatments. Various long-term ocular and extraocular complications were observed, which should be monitored for a long-term follow-up period. Our findings suggest that prevention should be emphasized more than treatment.

PURPOSE: To investigate the use of a retinal thickness deviation map generated from swept-source (SS) OCT images for hydroxychloroquine retinopathy screening. DESIGN: Retrospective cohort study. PARTICIPANTS: This study included 1192 Korean patients with a history of hydroxychloroquine treatment: 881 patients (1723 eyes) in the discovery set and 311 patients (591 eyes) in the validation set. Patients were screened for retinal toxicity using SS OCT, fundus autofluorescence, and standard automated perimetry. METHODS: According to the 2016 American Academy of Ophthalmology guidelines, hydroxychloroquine retinopathy was diagnosed by the presence of abnormalities on ≥1 objective structural tests alongside corresponding visual field defects. The 12 × 9-mm2 macular volume SS OCT scan was performed, and the retinal thickness deviation map was generated automatically using the built-in software. On this map, yellow (retinal thickness, <5% of the normative level) or red (<1% of the normative level) pixels were defined as abnormal. Abnormal findings were evaluated, and diagnostic criteria were developed based on the discovery set data; criteria were validated using the validation set data. MAIN OUTCOME MEASURES: The rate and patterns of abnormalities on the retinal thickness deviation map and sensitivity and specificity of the diagnostic criteria. RESULTS: The retinal thickness deviation map showed the following abnormal patterns in eyes with hydroxychloroquine retinopathy: pericentral (36.0%) or parafoveal (6.1%) ring, mixed-ring (34.2%), central island (13.2%), and whole macular thinning (10.5%). The criterion of ≥5 contiguous red pixels showing 1 of the 5 characteristic patterns in both eyes yielded the greatest diagnostic performance (sensitivity and specificity of 98.2% and 89.1% and of 100% and 87.5% in the discovery and validation set data, respectively). Moreover, the area of abnormal pixels on the map was correlated significantly with the mean deviation (P < 0.001) and pattern standard deviation (P < 0.001) on the Humphrey 30-2 test in eyes with hydroxychloroquine retinopathy. CONCLUSIONS: The retinal thickness deviation map may facilitate the objective evaluation of hydroxychloroquine retinopathy because it does not require subjective, morphologic evaluation of the outer retinal layers. The map has the potential to enhance hydroxychloroquine retinopathy screening when used in conjunction with conventional screening methods.
