Retinal Vein Occlusions occur when there is a blockage of veins carrying  blood with needed oxygen and nutrients away from the nerve cells in the retina.

There are two main types of occlusion:

• Central Retinal Vein Occlusion (CRVO)  is a blockage in the retina’s main vein.
• Branch Retinal Vein Occlusion (BRVO) is a blockage in a smaller vein.

Like with many eye conditions, early detection and prevention is key.
