Abstract

Sudden loss of visual acuity and visual field can occur in the vast majority of BRVO patients. One third to half of the patients recover from impared cision even without specific treatment, but it is unlikely when complication such as macula edema, capillary nonperfision, neovascularization and vitreous hemorrhage are accompanied. The authors reviewed 55 patients with branch retinal vein occlusion(55 eyes) in regard of the size of capillary non perfusion, and divided them into two groups; the perfused group(15 eyes) in which the area of capillary non perfusion is less than 5 disc diameter, and the nonperfused group(40 eyes) in which the area is more than 5 disc diameter. The freqnency of the development of neovascularization and vitreous hemorrhage, and the final visual outcome between two groups were compared. Neovascularization occurred in 3 eyes of perfused group and 23 eyes of nonperfused group, and vitreous hemorrhage occured in 4 eyes of nonperfused group, and vitreous hemorrhage occurred in 4 eyes of nonperfused group. There was no statistic al difference between two groups in the final visual acuity.
