If the central retinal vein or one of its main four branches is occluded, retinal hemorrhage and retinal edema subsequently occur and frequently cause low vision or blindness in adults 1. This is ...

Retinal vein occlusion (RVO) is classified into central RVO (CRVO) and branch RVO (BRVO) 1 and is an ischemic event that affects the retina, which is a structure derived from the central nervous ...

A retinal artery occlusion is a blockage in one of the blood vessels that supplies your retina with blood. It usually occurs suddenly and can cause vision loss without causing pain. A retinal artery ...

What Is Retinal Vein Occlusion? Arteries supply the retina with blood, and veins carry blood away. Sometimes, a vein becomes partially or completely blocked. This is called retinal vein occlusion, or ...

Retinal vascular occlusion (RVO) occurs when small veins in the back of the eye become blocked, and blood cannot flow through them. The condition can affect vision but does not cause total blindness.

Coronary artery occlusion is a partial or total blockage of one of the arteries in your heart. It can cause shortness of breath and chest pain but sometimes doesn’t cause symptoms until you experience ...

Data from trials investigating the effects and risks of endovascular thrombectomy for the treatment of stroke due to basilar-artery occlusion are limited. We conducted a multicenter, prospective, ...

Surgical occlusion of the left atrial appendage has been hypothesized to prevent ischemic stroke in patients with atrial fibrillation, but this has not been proved. The procedure can be performed ...

CRVO occurs when blood can no longer travel through the main blood vessel that brings blood to the back of the eye. This can cause swelling, and it may lead to vision loss. The retina is a layer of ...

The balloon occlusion test (BOT) is a medical technique that is employed to determine if an artery can be transiently blocked without significantly affecting blood flow to the organ concerned. It is ...
