The retina is supplied by blood from one main artery and carried back out by only one vein. Both form small branches inside the eye that help to supply the whole retina. Blockage of the central vein is called ‘central retinal vein occlusion’ and blockage of a smaller branch of the vein is called ‘branch retinal vein occlusion’. They can seriously affect the vision in which case treatment is required.
