Central retinal vein occlusion is blockage of the main vein carrying blood from the retina (the light sensitive membrane at the back of the eye). This means that blood cannot easily drain away from the retina, leading to a build-up of pressure in the retinal vein. As a result, fluid and blood start to leak from this vein, causing swelling and damage to the retina.
Central retinal vein occlusion affects men and women equally and is more common in older people. The disease is long-term debilitating because it causes loss of vision and can lead to blindness.
