The retina is located at the back of the eye and is responsible for receiving light from the front of your eye and converting this light into neural signals, which are processed by your brain into the images you see. In order to function efficiently, your retina requires healthy blood flow, as blood delivers vital nutrients and oxygen. When one or more blood vessels in your retina become blocked, a build-up of blood can inhibit the functioning of the retina and cause loss of vision.

CMV (cytomegalovirus) retinitis is a viral infection that affects the retina at the back of your eye. The retina's job is to receive images and transfer them to your brain for processing, so any infection in this area of your eye can damage your sight. CMV retinitis typically affects those with a weakened immune system, and the virus that causes the condition is related to the herpes virus. Those at an increased risk of developing this illness include organ transplant patients, those with HIV or aids, anyone undergoing chemotherapy and those taking medication to suppress the immune system.
