We did clinical analysis of 14 patients who had bilateral BRVO. The peak age distribution of the patients was between 60 and 69 years of age. In this 14 patients, there were 12 women and 2 men, and the most commonly associated systemic disease was hypertension(50%). In majority of patients, the interval of disease onset between two eyes was within two years. Complications developed, including maculopathy, retinal neovascularization, vitreous hemorrhage, glaucoma, and retinal detachment. Twenty one of 28 eyes(75%) had a final visual acuity of 0.4 or less. The larger the size of capillary nonperfusion was the higher was the incidence of neovasculgulation was an effective means of prevention of vitreous hemorrhage in BRVO with neovascularzation, and vitrectomy that was done in case of persistent vitreous hemorrhage improved final visual acuity. Our findings suggest that women with history of unilateral BRVO associated with hypertension in seventh, decade have high risk of occurrence in fellow eyes within two years.
