Purpose: To assess the safety and efficacy of selective retina therapy (SRT) using a Q-switched neodymium-doped yttriumlithium fluoride laser with feedback systems in patients with idiopathic central serous chorioretinopathy (CSC). Methods: This randomized clinical trial enrolled patients having at least 3-month symptom of CSC. From month 3 visit, allsubjects in both groups were eligible for SRT retreatment if they showed persistent or recurrent subretinal fluid (SRF). The primaryoutcome was complete resolution of SRF by optical coherence tomography at 3 months after treatment. The secondaryoutcomes were changes in SRF, central macular thickness (CMT) and best-corrected visual acuity at the 1-, 3-, and 6-monthexaminations. Results: Sixty-eight CSC patients were included (SRT, 31; control, 37). After 1 and 3 months, complete resolution of SRF wasachieved in 25.8% and 54.8% of SRT group and 17.6% and 35.1% of controls. The differences were not statistically significant(p = 0.424 and p = 0.142, respectively). However, mixed model for repeated measures analyses showed that the reduction ofSRF and CMT were observed earlier in SRT group than in the sham group (least squares mean difference, -59.7 μm; 95% confidenceinterval, -98.2 to -21.2; p = 0.0029; least squares mean difference -67.0 μm; 95% confidence interval, -104.8 to -29.2;p = 0.0007, respectively). Significant reduction of SRF (≥50% reduction from baseline) was more frequently observed in SRTgroup (80.6%) than the sham group (44.1%) at month 1 (p = 0.007). Early reduction of SRF and CMT was more abundant inSRT group with symptom duration less than 6 months. Treatment related serious adverse events were not observed. Conclusions: SRT using a Q-switched neodymium-doped yttrium lithium fluoride laser with feedback system was safe in thistrial and effective for early resolution of SRF in the CSC patients. Early intervention with SRT can be a safe alternative for patientswith acute symptomatic CSC.

PURPOSE:: To evaluate changes in external limiting membranes (ELMs) in the foveae of patients with surgically closed macular holes. METHODS:: In this retrospective observational case series, spectral-domain optical coherence tomography scan images were obtained from eyes of patients with macular holes closed after vitrectomy. The integrity of the ELMs was evaluated at the fovea. In eyes with a restored ELM, the reflectivity of the ELM was estimated. RESULTS:: At a mean of 19 months (range, 3.0–59.7 months) after surgery, the integrity of the ELM was restored in 21 (77.8%) of 27 eyes with closed macular holes. The ELM was not restored in six eyes with glial sealing, in which glial tissues were present in the entire retinal layer. All 21 eyes with restored ELMs had an area of hyperreflectivity within the ELM observed at the thinnest part of the fovea; this was associated with an underlying photoreceptor defect. CONCLUSION:: Abnormally hyperreflective ELMs were frequently observed at the thinnest point of the fovea after macular hole surgery. These hyperreflective ELMs may be newly formed after surgery.

Retinal pigment epithelial detachment (PED) is a feature of many chorioretinal disease processes, the most common of which is age-related macular degeneration. PED has different pathophysiology depending on the subtype, and may be associated with choroidal neovascularization. It shows a characteristic pattern in accordance with the imaging modality, but there is no clear differentiating method between its various subtypes. It is necessary to use multimodal imaging for evaluating PED. Optical coherence tomography (OCT) angiography, a new-developed imaging technique, is safe and convenient compared to conventional angiography, but it has narrow range of images and sometimes it does not get a clear image because of technical problems. Nevertheless, OCT angiography shows different images compared to prior imaging tools, so it will help understanding and diagnosing PED.

PURPOSE:: To compare choroidal thicknesses among eyes with early age-related maculopathy (ARM), neovascular age-related macular degeneration, polypoidal choroidal vasculopathy, and central serous chorioretinopathy. METHODS:: Patients with age-related maculopathy (37 eyes), neovascular age-related macular degeneration (24 eyes), polypoidal choroidal vasculopathy (12 eyes), and central serous chorioretinopathy (31 eyes) underwent spectral-domain optical coherence tomography evaluations using a choroid scanning protocol. A horizontal linear section comprising 50 averaged scans was obtained of each macula. The choroidal thickness was measured from the outer border of the retinal pigment epithelium to the inner scleral border. Twenty-nine subjects with healthy eyes served as a control group. Analysis of covariance tests were performed to evaluate the effects of various diagnoses on choroidal thickness after removal of variance (covariates = gender, age, and refractive error). RESULTS:: Among the different covariates, age was associated with choroidal thickness (fovea: F = 12.067, P = 0.001). After controlling for age differences, the choroid was thicker in polypoidal choroidal vasculopathy (319.92 ± 68.66 μm) and central serous chorioretinopathy (367.81 ± 105.56 μm) patients than in controls (241.97 ± 66.37 μm) and age-related maculopathy patients (186.62 ± 64.02 μm). However, there were no significant differences in mean choroidal thickness between neovascular age-related macular degeneration (226.46 ± 102.87 μm) and any of the other diagnoses. CONCLUSION:: The choroid was thicker in eyes with polypoidal choroidal vasculopathy or central serous chorioretinopathy than in control or age-related maculopathy groups.

Purpose: To report a case of delayed sealing of full-thickness macular hole associated with diabetic retinopathy after vitrectomy with silicone oil tamponade. Case summary: A 63-year-old woman visited our clinic complaining of decreased visual acuity in her left eye. Fundoscopy showed a full-thickness macular hole with vitreomacular traction in the left eye and bilateral proliferative diabetic retinopathy. The patient underwent uncomplicated phacoemulsification and pars plana vitrectomy with silicone oil tamponade because her vision in the contralateral eye was only light perception. She was unable to maintain a prone position postoperatively due to anterior chamber hyphema. At 1.5 months after surgery, vitreomacular traction was removed but the hole was not sealed as observed on optical coherence tomography. Approximately 3 months after vitrectomy, the macular hole was sealed with minimal subfoveal fluid. At 6 months after vitrectomy, the macular hole was closed completely with no subfoveal fluid.
