Branch Retinal Vein Occlusion (BRVO)
There are veins and arteries that carry blood throughout your body, including your eyes. The eyes' retina has one main vein and one main artery. If branches of the retinal vein become blocked, it's called branch retinal vein occlusion (BRVO).
When the vein gets blocked, fluid and blood will spill out into the retina. This fluid also causes the macula to swell, thus affecting your central vision. Eventually, nerve cells in the eye can die, and you'll lose vision in areas with poor blood circulation.
Central Retinal Vein Occlusion (CRVO)
Just like how the veins and arteries carry blood throughout the body, it also carries blood to the eyes. There is one main vein and one main artery in the eye, and when the main retinal vein gets blocked, it's called central retinal vein occlusion (CRVO).
After the vein is blocked, blood and fluid spill out into the retina, causing the macula to swell. This affects your central vision. Eventually, without proper blood circulation, the nerve cells in your eye can die, and you will lose more vision because of this.
