The Retina in the back of the eye, which senses light and sends vision signals to the brain, contains the one artery and vein in the eye. When plaque builds up and blocks the vein, blood and fluid can push into the retina. When the Main Retinal Vein becomes blocked it is called Central Retinal Vein Occlusion (CRVO). This blockage cases the walls of the vein to leak blood and fluid into the retina causing buildup in the Macula. This leads to central vision loss.
