Abstract

This study was performed to investigate the visual prognosis in ischemic and nonischemic central retinal vein occlusion(CRVO), to investigate the difference in clinical course of two types, and to identify prognostic factors for poor visual outcome. Fifty seven patients with CRVO were included. Eyes were classified into ischemic or nonischemic type by indirect ophthalmoscopy and fluorescein angiography. Among 58 eyes, 27 eyes(46.6%) were of the nonischemic CRVO and 31 eyes(53.4%) of the ischemic CRVO. Nonischemic CRVO was more common in patients under 45 years and had more benign clinical course than ischemic CRVO. Factors significantly related to visual outcome were initial visual acuity in ischemic CRVO(P<0.01) and the presence of systemic disease in nonischemic CRVO(P<0.01). Hypertension and diabetes were the most commonly associated systemic diseases. The leading causative factors for poor visual outcome were chronic macular edema and neovascular glaucoma in ishemic CRVO, and chronic macular edema in nonischemic CRVO.
