Abstract:
Objective To determine the effect of posterior vitreous detachment on the prognosis of branch retinal vein occlusion (BRVO). Methods One hundred and sixteen patients (116 eyes) with BRVO who underwent vitreous examination were retrospectively studied.The relationship of vitreous conditions to posterior segment neovascularization and macular edema was statistically investigated. Results In 40 ischemic cases,12 of 25 eyes (48.0%) with no posterior vitreous detachment (PVD) or partial PVD developed retinal or optic disc neovascularization ,or both,but only one of the 15 eyes (6.7%) with complete PVD developed neovascularization during a mean follow-up period of 10.7±2.2 months (P＜0.05).Diffuse macular edema was found in 45 eyes (38.8%).The incidence of macular edema was significantly higher in eyes with vitreomacular attachment (51.5%) than in those with vitreomacular separation (22.0%)(P＜0.01). Conclusion It was suggested that complete PVD may play a role in protecting eyes with BRVO from posterior segment neovascularization and macular edema.
