Retinal Vascular Occlusion – What it is, Causes and Treatments we should all know. Also, Retinal Vascular Occlusion affects the eye specifically the retina. The retina is the light-sensitive layer of tissue that houses the back of your eye . It’s covered with special cells called rods and cones that convert light into neural signals and send those signals to the brain so you can see. The retina is vital for vision. The vascular system includes blood vessels called arteries and veins, which carry blood throughout your body, including your eyes .
Your retina requires a constant supply of blood to ensure your cells get enough nutrients and oxygen. Blood also removes the waste your retina produces. However, it is possible for one of the vessels that carry blood to or from the retina to become blocked or have a blood clot . This is called Retinal Vascular Occlusion .
