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.
