The Macular Circulation State on BRVO According to Occlusion Site

ABSTRACT

We did clinical analysis on the macular circulatory state in 34 patients(34 eyes)who were diagnosed to have branch retinal vein occlusion and followed for over 6 months. After dividing them into two groups according to their occlusion sites, we evaluated the differences of foveal capillary ring state and size of macular ischemic area between the ones who had vein occlusion in their first retinal branches and the others in their second and the rest retinal branches. We were unable to find any differences between them. However, we could find statistical correlation between their visual acuities in acute stage of the disease and macular circulatory states even though we could not find any differences between their final visual acuities or degree of their visual improvement and circulatory states during follow up period.
