Retinal vein occlusion (RVO) is a common vascular disorder of the retina and one of the most common causes of vision loss worldwide. Specifically, it is the second most common cause of blindness from retinal vascular disease after diabetic retinopathy.
The blood then leaves the retina via the vein. The central retinal vein is located very close to the eye nerve (optic nerve). What is Central Retinal Vein Occlusion? Central Retinal Vein Occlusion (CRVO) is caused by a blood clot in the vein that drains the blood from the retina of the eye. The artery brings continuous blood to the retina but the blood can not leave the retina because of the block in the vein.
