Abstract

We observed 44 eyes of 43 patients who were diagnosed as macular edema in branch retinal vein occlusion(BRVO) by fluorescein angiogram, which had been followed up over 6 months after argon-green laser photocoagulation. In our cases, sixth decade of age was most commonly affected and there were no significant difference in sexual prevalence and laterality. Eighty six percent was 0.5 or less in initial visual acuity and 59.1% was 0.5 or more in final visual acuity. Increased visual acuity of 2 lines or more was 61.4% and decrease was only 9.1%. After laser treatment, visual improvements of each comparing group were as follow: 60.7% in superotemporal and 62.5% in inferotemporal, 56.5% in hypertensive patients and 66.7% in normotensive patients, 61.5% in below 6 months from onset of symptom until entry into laser photocoagulation and 61.1% in over 7 months, and there were no significant statistical difference.
