Retinal Vascular Diseases: Retinal Vein Occlusions
2 Self-Assessment AMA PRA Category 1 Credits™
Retinal vein occlusions refer to conditions in which there is an obstruction of blood flow out of the retina. This outflow obstruction can either affect the central retinal vein, causing central retinal vein occlusion (CRVO), or one of the branch retinal veins, resulting in branch retinal vein occlusion (BRVO). Visually significant complications can result including macular edema, retinal ischemia, and intraocular neovascularization. The prompt recognition and proper management of these conditions is important in limiting vision loss especially as newer treatment options become available.
