Abstract

We evaluated the macular circulatory change with fluores- cein angiography in 41patients (44eyes) who were diagnosed to have branch retinal vein occlusion and followed for 6 months or longer. Final visual acuity improved to 0.5 or better in more than half of cases in their last follow up. The initial corrected visual acuity and size of macular ischemic area were the potent prognostic factors. All cases that showed initial visual acuity of above 0.5 had smaller macular ischemic area and obtained final visual acuity of above 0.5. Visual prognosis of patients with ischemic area less than 1quadrant was much better than those with larger ischemic area. The state of perifoveal capillary network was also potent prognostic factor. Final visual prognosis was slightly better in patients with intact perifoveal capil-lary network than those with broken network. Systemic hypertension and venous occlusive site were not associated with visual prognosis. The relationship between visual improvement and state of perifoveal capillary network was not certain.
