Abstract

There have been various report about visual prognosis in branch retinal vein occlusion according to location and size of occluded vessel, status of perifoveal capillary ring, presence of retinal ischemia and hypertension. We therefore sought to determine prognostic indicators of BRVO by observing retrospectively the natural course of the BRVO with macular ischemia. To do that, we devide 63 eyes with BRVO into groups according to the macular perfusion status on high-quality fluorescein angiography. The patients without broken capillary ring exhibited better initial, final visual acuity and visual improvement. The patients with the extent of macular ischemia under 90degree exhibited better initial and final visual acuity but same visual improvement. There were no statistically significant difference in visual prognosis according to the status of perifoveal capillary ring, extent of macular ischemia and presence of hypertension.
