Biomarkers determining treatment interval of diabetic macular edema after initial resolution by anti-vascular endothelial growth factor.

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.

Macular hole with epiretinal proliferation: diagnostic value of en-face optical coherence tomography and clinical characteristics.

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.

RISK OF EXUDATION IN EYES WITH NONEXUDATIVE POLYPOIDAL CHOROIDAL VASCULOPATHY.

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.

THE IMPACT OF EARLY SURGICAL INTERVENTION ON ANISEIKONIA IN PATIENTS WITH EPIRETINAL MEMBRANE: A Prospective Cohort Study.

PURPOSE: To investigate the efficacy of early surgical intervention in ameliorating aniseikonia among patients with epiretinal membrane. METHODS: This prospective cohort study enrolled patients who underwent surgery for epiretinal membrane. Patients were divided into early (symptom onset within 1 year) and late (symptom onset ≥1 year) treatment groups. Changes in aniseikonia, best-corrected visual acuity, and tangential retinal displacement were assessed and compared at 6 and 12 months postoperatively. RESULTS: Of the 56 patients, 30 (53.6%) belonged to the early treatment group and 26 (46.4%) to the late treatment group. The early treatment group demonstrated a significant reduction in aniseikonia score at 6- and 12-month follow-up visits (-1.10 ± 1.50 [P = 0.002] and -1.18 ± 1.79 [P = 0.003], respectively); however, no improvement was observed in the late treatment group (0.98 ± 4.62 [P = 0.310] and 1.52 ± 4.35 [P = 0.124], respectively). The early treatment group showed larger tangential retinal displacement at the 12-month postoperative follow-up visit. In addition, the amount of tangential retinal displacement was associated with postoperative changes in aniseikonia. CONCLUSION: Early surgical intervention is helpful in improving aniseikonia in patients with epiretinal membrane. The degree of recovery in inner retinal displacement was associated with the improvement of aniseikonia.

Impact of Age-Related Macular Degeneration and Related Visual Disability on the Risk of Depression: A Nationwide Cohort Study.

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.

SPONTANEOUS REATTACHMENT OF RHEGMATOGENOUS RETINAL DETACHMENT: Observations of the Vitreoretinal Interface.

PURPOSE: To describe the clinical characteristics and posterior vitreous findings of spontaneous reattachment of rhegmatogenous retinal detachment (SRRRD). METHODS: Eighty-six eyes from 80 patients who were diagnosed with SRRRD (SRRRD group) and 92 eyes from 92 patients who had undergone successful scleral buckling for rhegmatogenous retinal detachment ( group for comparison) were included. Ultrawide field fundus imaging and spectral domain optical coherence tomography were performed to evaluate fundus characteristics and vitreoretinal interface. RESULTS: A significant difference was found in the proportion of complete posterior vitreous attachment between the SRRRD and rhegmatogenous retinal detachment groups (44.2% vs. 19.6%, P < 0.001). The incidence of atypical epiretinal tissue (AET) in the SRRRD group was 14% (12 of 86 eyes), whereas none of the eyes in the rhegmatogenous retinal detachment group exhibited AET. In SRRRD eyes with AET, the visual acuity was lower (logarithm of the minimum angle of resolution, 0.51 ± 0.57 vs. 0.14 ± 0.15, P < 0.001), the mean age was higher (years, 61.7 vs. 39.4, P < 0.001), and the SRRRD lesion extent was wider (clock hours, 5.67 vs. 3.70, P = 0.004) than in SRRRD eyes without AET. CONCLUSION: Compared with the rhegmatogenous retinal detachment group, the SRRRD group had a higher incidence of posterior vitreous attachment. Furthermore, AET was a significant comorbidity in the eyes with SRRRD, particularly in the elderly and the area of presumed reattachment over two quadrants and was related to worse functional outcomes.

Police decisions to found sexual assault cases: The influence of community-level factors and space.

Previous research has examined the influence of individual- and case-level factors on police decisions in sexual assault cases, with little attention paid to community-level factors. This study examined the association between community-level factors and police decisions to found sexual assault cases. Founding is the first decision officers make and determines whether a case is investigated. An archival data set of N = 8015 sexual assaults reported to a Midwestern city police department was used. Ordinary least squares (OLS) regression was first used to examine the relationship between six community-level factors and founding rates within the city's 77 communities. Geographically weighted regression (GWR) was then used to examine whether these relationships varied by space. OLS results revealed communities with a greater proportion of Black residents, Latinx residents, Asian residents, and higher income had significantly higher founding rates. GWR results replicated these findings indicating these relationships varied significantly by space throughout the city. In contrast to the OLS, GWR results indicated communities farther from a rape crisis center had higher founding rates. Findings underscore the importance of analyzing localized effects and examining individual-, case-, and community-level factors on sexual assault case outcomes in the criminal legal system.

The clinical and pathogenic significance of atypical epiretinal tissue in macular hole.

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.

Relationships Between Physical Activity Metrics of Intensity and Diabetes.

INTRODUCTION: Physical activity (PA) prevents diabetes-associated complications. Little is known about what constitutes effective PA interventions to mitigate diabetes. Identifying PA metrics associated with the efficacy of PA interventions will provide insight into devising strategies to treat diabetes. PURPOSE: The aim of this study was to analyze the relationships between preclinical and postclinical variables from a 10-week intervention designed to increase PA in adults with diabetes. METHODS: A secondary analysis was performed to evaluate data using Wilcoxon rank sum test, permutation test and Spearman correlation to analyze hemoglobin A1c (HbA1c), weight, and PA metrics (maximum steps per episode, cadence, daily steps, and 6-minute walk). RESULTS: Poststudy HbA1c level was associated with maximum steps (r = -0.63, P = .03) and 6-minute walk (r = -0.50, P = .09). Baseline weight was associated with average cadence (r = -0.76, P = .007), and poststudy weight was associated with average cadence (r = -0.60, P = .041) and maximum steps (r = -0.62, P = .03). CONCLUSIONS: Cadence and maximum steps per episode reflect PA intensity and were associated with HbA1c and weight in adults with diabetes.

CHOROIDAL NEOVASCULARIZATION SECONDARY TO PHOTODYNAMIC THERAPY FOR CENTRAL SEROUS CHORIORETINOPATHY: Incidence, Risk Factors, and Clinical Outcomes.

PURPOSE: To investigate the incidence, risk factors, and clinical outcomes of complicated choroidal neovascularization (CNV) after reduced-fluence photodynamic therapy (PDT) for central serous chorioretinopathy. METHODS: This is a retrospective consecutive interventional study including 559 eyes from 520 patients treated by reduced-fluence PDT for central serous chorioretinopathy. The incidence of complicated CNV within 3 months after PDT was calculated. Baseline demographics and ocular findings were investigated to identify risk factors. The clinical course of complicated CNV was analyzed. RESULTS: Seven cases experienced development of active CNV after PDT within 3 months with a median interval of 4 weeks (range, 2-12 weeks). The incidence was estimated as 1.25% (95% CI, 0.55-2.62%). Complicated CNV developed in 6 among 138 eyes (4.35%) with flat irregular pigment epithelial detachment and in 1 among 421 eyes (0.24%) without flat irregular pigment epithelial detachment (P < 0.001, Fisher's exact test). The median best-corrected visual acuity recovered from 20/100 at the time of CNV development to 20/20 after anti-vascular endothelial growth factor injections (median, 3 times). CONCLUSION: In approximately 1%, reduced-fluence PDT for central serous chorioretinopathy may be complicated by CNV, which can be well controlled with anti-vascular endothelial growth factor injection. Flat irregular pigment epithelial detachment increases the risk of secondary CNV following PDT.

FEMALE REPRODUCTIVE FACTORS AND THE RISK OF EXUDATIVE AGE-RELATED MACULAR DEGENERATION: A Nationwide Cohort Study.

PURPOSE: To evaluate the association between female reproductive factors and the incidence of exudative age-related macular degeneration (AMD). METHODS: A total of 1,297,388 postmenopausal women over 50 years of age who participated in both national health screening and cancer screening in 2009 were identified using the Korea National Health Insurance System database. Data on female reproductive factors were collected using a self-administered questionnaire. Patients were followed up until 2018, and the incident cases of exudative AMD were identified. The hazard ratios and 95% confidence intervals for exudative AMD were estimated using the multivariable-adjusted Cox proportional hazard model. RESULTS: During a mean follow-up of 7.27 years, 4,086 patients were newly diagnosed with exudative AMD. The hazard ratio (95% confidence intervals) for exudative AMD was 1.14 (1.01-1.31) for a reproductive period ≥40 years compared with a reproductive period <30 years, 1.72 (1.48-2.00) for patients with ≥5 years of hormone replacement therapy, and 1.29 (1.09-1.52) for those with 2 to 5 years of hormone replacement therapy compared with those who never underwent hormone replacement therapy. CONCLUSION: Female reproductive factors were associated with the risk of exudative AMD. Greater lifetime exposure to endogenous and exogenous estrogen was associated with a higher incidence of exudative AMD.

Measuring Community Mobility in Survivors of Stroke Using Global Positioning System Technology: A Prospective Observational Study.

BACKGROUND AND PURPOSE: Returning to community mobility is important for people recovering from a stroke, yet few studies have directly measured this construct following inpatient rehabilitation. Using global positioning system (GPS) technology, we examined community mobility of survivors of stroke (SS) over the first year after discharge and compared them to an age-matched comparison group without neurological impairment. METHODS: We conducted a prospective observational study that included SS (n = 14) and age- and location-matched comparison subjects (CS; n = 6). All participants identified target locations important to their community mobility goals and wore a GPS unit during the first, fifth and ninth weeks after discharge, or from baseline for CS, and at 26 and 52 weeks' follow up. The 6-minute walk test (SMWT), Berg balance test (BBT), Reintegration to Normal Living (RNLI), and Short Form-36 Quality of Life Survey Physical Functioning domain (SF-36-PF) were collected. Number of trips and percentage of targets visited were extracted from GPS data. RESULTS: Twelve of 14 SS completed 9 weeks, 7 completed the full year, and no CS withdrew. The SS took fewer trips and attained fewer targets compared with CS at weeks 1 and 9, but not at weeks 5, 26, and 52. All 4 clinical outcome measures were significantly correlated to trips (Spearman r for SMWT = 0.5067, BBT = 0.3841, RNLI = 0.4119, and SF-36-PF = 0.4192). DISCUSSION AND CONCLUSIONS: Directly measured community mobility in SS was decreased through 9 weeks following discharge from inpatient rehabilitation. The limited strength of bivariate correlations between clinical measures and number of trips supported the uniqueness of the community mobility construct.Video Abstract available for more insights from the authors (see Supplemental Digital Content 1, available at: http://links.lww.com/JNPT/A277).

PHOTODYNAMIC THERAPY FOR SYMPTOMATIC SUBFOVEAL RETINAL PIGMENT EPITHELIAL DETACHMENT IN CENTRAL SEROUS CHORIORETINOPATHY: Outcomes and Prognostic Factors.

PURPOSE: To report the clinical outcomes of reduced-fluence photodynamic therapy (PDT) for symptomatic subfoveal retinal pigment epithelial detachment (RPED) in central serous chorioretinopathy and identify prognostic factors affecting treatment outcome. METHODS: This retrospective interventional study included 35 eyes of 35 patients with serous subfoveal RPED with choroidal hyperpermeability. Cases with evidence of age-related macular degeneration were excluded from the study. Reduced-fluence PDT was applied to each patient. Best-corrected visual acuity, anatomical resolution of RPED, subjective symptom improvement, and complications were analyzed. RESULTS: One month after reduced-fluence PDT, 28 eyes (80.0%) manifested complete resolution of subfoveal RPED. Among the patients whose eyes manifested complete resolution, 19 (67.9%) reported subjective vision improvement. This subjective improvement was significantly associated with the presence of dysmorphopsia at baseline. Logarithm of the minimal angle of resolution visual acuity improved from 0.15 (Snellen equivalent of 20/28) to 0.09 (20/25) between baseline and 3 months after PDT (P = 0.008). Older age and increased RPED height were independent risk factors of poor resolution of RPED after PDT. The mean follow-up period after treatment was 10.4 ± 13.6 months; recurrence of RPED did not occur in any case. CONCLUSION: Subfoveal RPED in central serous chorioretinopathy responded well to reduced-fluence PDT, especially in younger patients with less RPED. Dysmorphopsia, rather than decreased visual acuity, is a main symptomatic presentation in subfoveal RPED.

Fibromyxoma of the Orbit.

Fibromyxomas are rare tumors that are not commonly seen in the orbit. The authors present a case of orbital fibromyxoma. A 42-year-old male presented with proptosis of the right eye that began 1 month prior. Magnetic resonance imaging revealed the presence of an orbital mass in the right eye, with low signal intensity on T1-weighted images and heterogeneous high-signal intensity on T2-weighted images. The patient underwent excisional biopsy of the orbital tumor through a Krönlein approach. The tumor originated from the inferior rectus muscle. Histopathologic analysis demonstrated scattered spindle cells, with both fibrous and myxoid stroma. Immunohistochemical staining was positive for Vimentin and negative for S-100 protein and CD34. The tumor was diagnosed as orbital fibromyxoma. The patient showed no evidence of recurrence over 18 months of follow-up after operation.

Prospective study of bilateral mix-and-match implantation of diffractive multifocal intraocular lenses in Koreans.

BACKGROUND: To evaluate monocular and binocular visual outcomes for near, intermediate, and far distance in patients implanted with diffractive multifocal intraocular lenses (IOLs) with different add power contralaterally. METHODS: This is a prospective contralateral study. Two diffractive multifocal IOLs with different added power were implanted bilaterally in twenty patients. TECNIS® ZKB00 (+ 2.75 D) was implanted in a dominant eye, and TECNIS® ZLB00 (+ 3.25 D) was implanted in a non-dominant eye. Uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA), uncorrected near visual acuity (UNVA), and manifest refraction (MR) values were measured at 1 month and 3 months postoperatively. At the 3-month follow-up, defocus curve, contrast sensitivity, and reading performance were evaluated. Quality of vision, overall satisfaction, and spectacle independence were evaluated by questionnaire. RESULTS: Postoperative binocular UDVA, visual acuity at 80 cm, 60 cm, 50 cm, 43 cm, 33 cm were - 0.08 ± 0.10, 0.12 ± 0.14, 0.09 ± 0.09, 0.07 ± 0.11, 0.14 ± 0.09, 0.25 ± 0.11 logMAR. The binocular defocus curve showed an extended range of good visual acuity with sharp vision being observed from 0 D to - 2.50 D defocus (logMAR≤0.1). Reading performance was significantly improved compared to baseline. All patients were spectacle-free at distance, and 94.74% of the patients did not require glasses for near and intermediate vision. CONCLUSIONS: Mix-and-match implantation of diffractive multifocal IOLs with different add power provides an excellent wide range of vision, as well as high levels of visual quality and patient satisfaction.

Comparison of astigmatism prediction error taken with the Pentacam measurements, Baylor nomogram, and Barrett formula for toric intraocular lens implantation.

BACKGROUND: To evaluate and compare the astigmatism prediction errors taken with the Pentacam measurements, Baylor nomogram, and Barrett formula for toric intraocular lens (IOL) implantation. METHODS: Phacoemulsification with toric Precizon IOL implantation was performed in 41 eyes with corneal astigmatism (range, 1 to 5 diopters (D)) determined by IOLMaster and SimK on Pentacam. Preoperative corneal astigmatism measurements were obtained from IOLMaster readings (IOLMaster, Baylor-IOLMaster, and Barrett-IOLMaster) and Pentacam readings (SimK, Baylor-SimK, Barrett-SimK, wavefront, true net power, total corneal refractive power, and vector derived by manual vector summation using corneal front and back astigmatism). Prediction error and intraclass correlation coefficient (ICC) between the measured (or calculated) astigmatism by IOLMaster and Pentacam and the estimated corneal astigmatism estimated by IOL toricity power and residual astigmatism were determined. RESULTS: The centroid errors in prediction error with IOLMaster, SimK, Baylor-IOLMaster, Baylor-SimK, Barrett-IOLMaster, Barrett-SimK, wavefront, true net power, total corneal refractive power, and vector were 0.59@103, 0.61 @103, 0.37@161, 0.41@162, 0.24@171, 0.36@162, 0.42@106, 0.04@8, 0.07@82, and 0.03@82, respectively, in with-the-rule (WTR) astigmatism eyes at postoperative 3-month. They were 0.22@87, 0.20@74, 0.16@21, 0.54@10, 0.43@3, 0.33@19, 0.51@25, 0.31@58, 0.29@50, and 0.14@50 in against-the-rule (ATR) astigmatism eyes. Of the ten modalities, vector showed the lowest WTR astigmatism prediction error and the highest ICC between the predicted and the estimated corneal astigmatism for both WTR and ATR eyes. CONCLUSION: Vector summation using anterior and posterior corneal surface power taken with the Pentacam yields the least astigmatism prediction error and is a promising tool for determining toric IOL cylinder power.

Outcomes of epiretinal proliferation embedding technique in the surgery for full-thickness macular hole.

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.

Foveal atrophy in patients with active central serous chorioretinopathy at first presentation: characteristics and treatment outcomes.

BACKGROUND/AIMS: This study aimed to investigate the clinical characteristics and treatment outcomes of patients with active central serous chorioretinopathy (CSC) and foveal atrophy. METHODS: Patients diagnosed with active idiopathic CSC using multimodal imaging and followed up for at least 6 months were included. They were divided into two groups (foveal atrophy group vs foveal non-atrophy group) according to a cut-off central foveal thickness of 120 µm on baseline optical coherence tomography (OCT). Baseline characteristics, angiographic and tomographic features and treatment outcomes were compared between the two groups. RESULTS: Of the 463 patients, 92 eyes of 92 patients (19.9%) were in the foveal atrophy group and 371 eyes of 371 patients (80.1%) were in the foveal non-atrophy group. The baseline subretinal fluid (SRF) height was 111.3±76.8 µm in the foveal atrophy group and 205.0±104.4 µm in the foveal non-atrophy group on OCT images (p<0.001). Complete resolution of SRF after treatment was noted in 60.4% and 93.5% of patients in the foveal atrophy and foveal non-atrophy groups at the final visit, respectively (p<0.001). The foveal atrophy group showed worse visual acuity at baseline (logarithm of the minimum angle of resolution, 0.43±0.33 vs 0.13±0.18, p<0.001) and final visit (0.41±0.32 vs 0.05±0.15, p=0.035). CONCLUSIONS: CSC with foveal atrophy was associated with a shallow SRF height, low treatment efficacy and poor vision before and after treatment. We suggest that early active treatment should be considered for eyes with CSC accompanied by a persistent shallow SRF and foveal atrophy.

COVID-19 Vaccination and Ocular Adverse Events: A Self-Controlled Case Series Study From the Entire South Korean Population.

PURPOSE: This study aimed to assess the risk of ocular adverse events, including retinal artery occlusion (RAO), retinal vein occlusion (RVO), noninfectious uveitis (NIU), noninfectious scleritis (NIS), optic neuritis (ON), ischemic optic neuropathy (ION), and ocular motor cranial nerve palsy (OMCNP), following Coronavirus Disease 2019 (COVID-19) vaccination. DESIGN: Population-based self-controlled case series METHODS: This study utilized nationwide claims and vaccination data provided by the Korea National Health Insurance Service and Korea Disease Control and Prevention Agency. From the entire South Korean population of 52 million individuals, patients with incident RAO, RVO, anterior NIU, nonanterior NIU, NIS, ON, ION, or OMCNP between January 2021 and March 2022 were included. The postvaccination risk period was defined as up to 56 days after COVID-19 vaccination. The relative incidence rate ratios (IRRs) for RAO, RVO, anterior NIU, nonanterior NIU, NIS, ON, ION, and OMCNP during the risk periods were measured using conditional Poisson regression. RESULTS: The study included 6,590, 70,120, 137,958, 17,921, 15,492, 2,039, 49,089, and 11,312 cases of incident RAO, RVO, anterior NIU, nonanterior NIU, NIS, ON, ION, and OMCNP, respectively. The IRRs (95% confidence interval) during the early risk period (0-28 days) were 0.95 (0.88-1.01), 0.96 (0.94-0.98), 0.93 (0.91-0.94), 0.93 (0.89-0.96), 0.96 (0.92-1.01), 1.04 (0.92-1.18), 0.98 (0.95-1.00), and 0.91 (0.86-0.96), respectively. In the late risk period (29-56 days), the IRRs were 0.96 (0.89-1.03), 0.93 (0.91-0.96), 0.96 (0.95-0.98), 1.00 (0.95-1.04), 0.96 (0.91-1.01), 1.00 (0.87-1.15), 1.01 (0.98-1.04), and 0.95 (0.90-1.01), respectively. CONCLUSION: COVID-19 vaccination did not increase the risk of incident RAO, RVO, anterior NIU, nonanterior NIU, NIS, ON, ION, or OMCNP during the postvaccination period.
