What is the retinal artery?

The central retinal artery is a blood vessel inside the eye. It provides essential nutrients to the retina. The retina lines at the back of the eye and is full of cone cells and rods, which transmit messages to the occipital lobe in the brain's cerebral cortex.

What causes retinal occlusion?

Retinal vein occlusion happens when a blood clot blocks the vein. Sometimes it 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.

How is retinal artery occlusion diagnosis?

Diagnosis. The diagnosis is suspected when a patient has acute, painless, severe vision loss. Funduscopy is usually confirmatory. Fluorescein angiography is often done and shows absence of perfusion in the affected artery.

How common is retinal occlusion?

Globally, an estimated 16.4 million adults are affected by RVO (2.5 million by CRVO and 13.9 million by BRVO). The age and sex standardized prevalence is 5.20 (per 1000) for any RVO, 4.42 for BRVO, and 0.80 for CRVO in the population aged ≥30 years.

Is central artery of retina an end artery?

The central retinal artery is an end-artery that joins the optic nerve 1cm behind the globe and enters the retina on the optic nerve head.

What type of artery is the central retinal artery?

The central retinal artery (Zinn's artery) is a branch of the ophthalmic artery. It provides arterial supply to the inner surface of the eye. Specifically, this artery provides the majority of the retinal arterial supply except for the layer of cones and rods.

Can vascular occlusion lead to a stroke?

Patients with acute central retinal artery occlusion (CRAO) are at heightened risk of having a subsequent stroke or heart attack and need to be sent to an ER immediately.

Can retinal artery occlusion be cured?

Unfortunately, there is no cure or good treatment for retinal artery occlusions. The main cause of vision loss in patients with retinal artery occlusions is due to a lack of blood flow to the retina.

Can retinal vein occlusion go away?

There's no cure for retinal vein occlusion. Your doctor can't unblock the retinal veins. What they can do is treat any complications and protect your vision.

What is a stroke in the eye called?
