What is Retinal Vein Occlusion (RVO)?

Retinal vein occlusion occurs when one of the four retinal veins, or the central vein, becomes blocked by a blood clot. This means that blood cannot drain away from the retina as easily.

Is it a form of stroke?

Any blockage in an artery or vein is considered an occlusion or stroke. When the flow of blood returning from the retina is blocked, it is often because a blot clot is blocking the retinal vein. This condition is called retinal vein occlusion (RVO). If the artery is blocked (retinal artery occlusion), the supply of oxygen and nutrients is severely disrupted and leads to more serious consequences to vision.
