Abstract

Hemispheric retinal vein occlusion(HSRVO) involves the venous return from approximately one-half of the retina and have characteristics of both central retinal vein occlusion and branch retinal vein occlusion. We have clinically analized in 20 patients that were classified as the HSRVO from June 1988 to December 1993 in the aspect of spheric distribution of diseased retina, sex, age, associated systemic diseases, ocular sequale. The patients were comprised of 6 males and 14 females. The average age was 57.5 years. There were no significant differences in superior and inferior spherical distribution. The most common associated systemic disease was hypertension(40%) and the next was diabets mellitus(20%). As sequle, macula edema in 9 cases and retinal neovascularization and vitreal hemorrhage in 5 cases were found. But iridis rubeosis or neovascular glaucoma was not found. Clinically, HSRVO is closer to branch retinal vein occlusion than central retinal vein occlusion.
