Retinal vein occlusion (RVO) is the second most common retinal vascular disease after diabetic retinopathy. RVO exists in two subtypes: CRVO (central retinal vein occlusion), which is less common and represents occlusion of the central retinal vein, and BRVO (branch retinal vein occlusion), which is 4-6 times more common and represents occlusion of some branches of central retinal vein. RVO is a relatively common and frequently devastating cause of visual loss mainly in older patients. Its prevalence varies according to studies in overall populations from 5.2 to 16 per 1000. Visual acuity is primarily decreased due to macular edema and retinal ischemia.

Central Retinal Vein

Retinal vein occlusion (RVO) is one of the most common causes of acquired retinal vascular anomalies in adults and is a common cause of visual loss. There is little data on the prevalence of RVO in the general population, although it is at least as early as 1855 and there are more than 3000 publications. The number of studies on the incidence of RVO is relatively small. Reduced vision in patients affected by RVO can result from retinal ischemia and/or accumulation of fluid in the center of the retina (macular edema). In this review, studies on epidemiology, prevalence, and incidence in central retinal vein occlusion and macular edema were summarized and evaluated.
