Types of Retinal Vein Occlusion​

There are two types of RVO:

Central Retinal Vein Occlusion (CRVO)

In this type of RVO, the blockage occurs in the main retinal vein. It is the least common form of RVO, but is still a major sight-threatening condition.

Branch Retinal Vein Occlusion (BRVO)

The veins in the retina branch out and drain the blood from all areas of your retina. BRVO occurs when one segment of these branched veins becomes blocked. This form of RVO is about five times more common than CRVO.
