What happens when a retinal vein is blocked?
When a retinal vein is blocked, it cannot drain blood from the retina. This leads to hemorrhages (bleeding) and leakage of fluid from the blocked blood vessels.

There are two types of RVO: 1 Central retinal vein occlusion (CRVO) is the blockage of the main retinal vein. 2 Branch retinal vein occlusion (BRVO) is the blockage of one of the smaller branch veins.
What is the function of blood vessels in the brain?
Blood vessels provide this supply. In a stroke, a small blood clot blocks the flow of blood through one of the arteries in the brain, and the area that is not getting blood becomes damaged.
Where is the lens located in the eye?
The front of the eye contains a lens that focuses images on the inside of the back of the eye. This area is the retina. The retina is where the eye focuses the images we see. It is covered with special nerve cells which convert light into signals that are sent via the optic nerve to the brain, where they are recognized as images.

What happens when your eye is blocked?
It's similar to retinal artery occlusion, which is sometimes called an eye stroke. The damage happens when a blocked vein keeps blood from draining from the retina. That raises pressure inside your eye, which can cause bleeding, swelling, and fluid leaks. Retinal vein occlusions can harm your eye in minutes.
What causes blurry vision?
Eye Stroke. Retinal Vein Occlusion. Glaucoma Treatment. Your retina is a thin layer of tissue that lines the back of your eyeball.

This can give you blurry vision or even sudden permanent blindness ...

What is retinal vein occlusion?
Retinal vein occlusion usually occurs when one of the following occurs: A retinal vein is 'pinched off' through the pressure of an artery lying on top of the vein. A retinal vein is blocked with a blood clot or fragment of fatty deposit (atherosclerotic plaque) in the wall of the artery.

The combination of high blood pressure, high lipid levels and diabetes is called metabolic syndrome and is a particularly strong risk factor for retinal vein occlusion. For each of these risk factors, good management will greatly reduce the risk of complications, including retinal vein occlusion.
What is the name of the membrane that lines the back of the eye?
The retina is a thin, light-sensitive membrane that lines the back of your eye. An occlusion is a medical term for blockage so retinal vein occlusion means the retinal vein is blocked. This stops blood draining away from the retina and blood 'backs up' behind the blockage.

Retinal vein occlusion can cause very profound visual loss. This is more commonly seen in central retinal vein occlusion, which affects the whole of the retina, (including the macula where central vision is formed).
What is fluorescein angiography?
Fluorescein angiography. This allows the ophthalmologist to look in detail at the blood vessels in the eye, and how the blood is flowing through them. A dye is injected (usually into your arm). This dye will then pass to, and move through, the blood vessels at the back of your eye.
What is the back of the eye?

Cardiovascular diseases are diseases of the heart or blood vessels caused by atheroma. Patches of atheroma are like small fatty lumps that develop within the inside lining of arteries. Atheroma is also known as 'hardening' of the arteries (atherosclerosis). A patch of atheroma makes an artery narrower.
What causes a bleed in the eye?
Retinal vein occlusion is a blockage in the blood vessel of your eye that can result in sight loss. The retinal veins carry away used blood from the nerve cells in the retina. When one of these veins becomes blocked, the used blood cannot drain away. This causes the blood to collect in the veins, which causes swelling and hemorrhage (bleeding).
