Purpose: To evaluate the association between disorganization of the retinal inner layers (DRIL) and visual acuity (VA) after anti-VEGF treatment for macular edema (ME) due to branch retinal vein occlusion (BRVO). Methods: Sixty eyes of 60 patients were retrospectively investigated. Baseline characteristics and factors analyzed on optical coherence tomography (OCT) examination at the final visit were evaluated in association with VA at the final visit. Results: DRIL was detected in 39 eyes at the final visit. The central subfield thickness was significantly higher in the eyes with DRIL. While DRIL length at the final visit showed a significant association with final VA on univariable analysis, only age and ellipsoid zone disruption on OCT at the final visit were found to be significantly associated with VA on multivariable analysis. Conclusions: DRIL had only a minor role in determining VA after anti-VEGF treatment for ME due to BRVO.
MH with or without RD in highly myopic eyes could be successfully treated with PPV leaving ILM flap floating in vitreous fluid at the edge of the MH. After the ILM peeling, further manipulation of the ILM flap to cover the MH would not be necessary for the treatment of MH in high myopia.
PurposeTo study the pathophysiology of subfoveal serous retinal detachment (SRD) observed in eyes with extramacular branch retinal vein occlusion (BRVO).MethodsWe retrospectively reviewed the medical records of nine patients (nine eyes) with extramacular BRVO with macular complications that were examined using optical coherence tomography (OCT).ResultsExtramacular BRVO was observed in the inferior area in three eyes, in the superior area in five eyes, and in the nasal area in one eye. Visual acuity was moderately disturbed (median, 0.6; range, 0.2–0.9, measured using the Landolt chart). One eye showed extensive SRD that was connected to the area affected by BRVO through the subretinal space. In eight of the eyes, focal SRD was observed beneath the fovea without subretinal connections to the area affected by BRVO. However, all these eyes showed marked retinal swelling in the outer retina, particularly in the outer plexiform layer. In two of the eyes, detailed OCT examinations showed a small break on the external surface of the retina connecting the swollen outer retina with the underlying SRD. All eyes showed hyperreflective foci in the outer retina, most frequently along the inner boundary of the outer plexiform layer and external limiting membrane.ConclusionExtramacular BRVO is often accompanied by focal SRD beneath the fovea. Leakage from the retinal capillaries affected by BRVO travelled via the outer plexiform layer and caused SRD under the fovea.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
