Retinal Vein Occlusions

Branch Retinal Vein Occlusion (BRVO) occurs when a small artery, hardened by age and/or high blood pressure compresses or squashes a retinal vein where they cross over. It usually affects only one eye. Vision may be blurred, distorted or obscured by intraocular bleeding.

Central Retinal Vein Occlusion (CRVO) causes very poor vision because the circulation within the eye slows down. The effects can range from slightly blurry vision through to a blind, painful eye.
