Epidemiology, Prevalence and Incidence in Central Retinal Vein Occlusion and Macular Edema

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 has a definition by the earliest until 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.
