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 Branches of the Retinal Vein become blocked it is called Branch Retinal Vein Occlusion (BRVO). If the branches blocked supply blood to the macula which is responsible for central vision, some central vision loss occurs
