Retinal vein occlusion happens when a blood clot blocks the vein, causing varying degrees of vision loss. Treatment options depend on the location and size of the blockage.
The retina requires a constant blood supply to and from its tissues. When a clot blocks the retinal vein, the used blood in your retina can’t be drained away, causing swelling, haemorrhage and bleeding that can damage your sight.
Sometimes, retinal vein occlusion happens because the veins of the eye are too narrow.
It is more likely to occur in people with diabetes, and possibly high blood pressure, high cholesterol levels, or other health problems that affect blood flow.
The symptoms of retinal vein occlusion range from subtle to very obvious.

Treatment decisions depend on whether your vision loss involves the macular or not.
