RETINAL VASCULAR DISEASES
Central Retinal Vein Occlusion
Central retinal vein occlusion (CVO) is characterized by diffuse retinal hemorrhages in all quadrants of the retina, and dilated and tortuous retinal veins.
The clinical appearance may vary from a few scattered retinal hemorrhages with a few cotton-wool spots to very extensive retinal hemorrhages occurring throughout the fundus.
The two major complications associated with CVO are persistent macular edema, and neovascular glaucoma secondary to iris neovascularization.
