Abstract

The clinical results in 102 eyes of 97 patients with Branch Retinal Vein Occlusion(BRVO) were evaluated in aspect of distribution, associated findings, sequelae, early and final visual acuities, and the effect of argon laser photocoagulation. There were no significant differences in morbidity rate between male and female or between right and left eye. 68.6% of all BRVO were affected in superotemporal branch veins. As sequelae, cystoid macular edema in 58 cases, retinal neovascularization in 22 cases, vitreous hemorrhages in 14 cases, vitreous tractional band in 2 cases, and non-rhegmatogenous retinal detachment in 2 cases were found. Photocoagulation was performed with an argon laser at retinal neovascularization in 20 eyes, capillary non-perfusion and cystoid macular edema in 5 eyes, and retinal detachment in 2 eyes. Photocoagulation was an affective means of reducing macular edema and decreased the risk of neovascularization and vitreous hemorrhages from sites of large capillary non-perfusion and retinal neovascularization.
