      Central retinal artery occlusion (CRAO) is an ophthalmologic emergency and an important cause of acquired blindness. Occlusion of the central retinal artery is usually secondary to one or more serious systemic diseases, often carotid artery or cardiac valvular disease, although hypercoagulability, atrial fibrillation and autoimmune diseases are significant contributors as well.[1,2] A minority ...

      Central Retinal Artery Occlusion: Pathophysiology. Etiology is typically emboli from carotid artery or heart lodging in central retinal artery at laminar constriction. Emboli of cardiac origin are more likely than emboli of carotid origin to cause artery occlusion. Other possible etiologies: Giant cell arteritis (GCA) Intraluminal thrombosis

      There are two main types of retinal vein occlusions: Central Retinal Vein Occlusion (CRVO) and Branch Retinal Vein Occlusions (BRVO). The names correspond to where the blockage is located. The major cause of both CRVO and BRVO is mechanical in nature with the vein being compressed by an anatomical narrowing or an artery that has become hardened ...

      Central retinal artery occlusion is the blockage of blood to the retina of one eye. It usually causes sudden loss of eyesight in one eye. You are higher risk if you are older or have high blood pressure, glaucoma, or diabetes. You are also at higher risk if your blood is thicker and stickier than normal.

      If the central artery becomes blocked, then little to no blood will enter your eye, and it will affect all of your vision in that eye. This type of occlusion is a central retinal artery occlusion (CRAO). If the blockage happens in one of the branch arteries, then only some of your sight in that eye will be affected.

      There are two main types of retinal artery occlusions: Central Retinal Artery Occlusion (CRAO) and Branch Retinal Artery Occlusions (BRAO). The names correspond to where the blockage is located. The major cause of both CRAO and BRAO is a blockage of the artery from an embolism (usually a cholesterol or calcific plaque) that has migrated from ...

      Central retinal artery occlusion (CRAO) is an ischemic injury to the retina that frequently results in permanent blindness.1 The central retinal artery has a lumen diameter of roughly 2mm and occlusion of this artery is usually the result of an embolus lodging either at the point where the vessel penetrates the optic nerve or just prior to the point where it enters the globe as it crosses the ...

      Slide: Angiogram of retinal vessels. Branch Retinal Artery Occlusion. In some cases, instead of having obstruction of the central retinal artery, an embolus can wind up in a smaller branch, causing a branch retinal artery occlusion. The area of the retina that is perfused by the obstructed branch will lose its transparency and its function.
