CRVO - Central Retinal Vein Occlusion
What is Central Retinal Vein Occlusion?
Central retinal vein occlusion (CRVO), is a medical condition in which there is a blockage of blood flow to the retina. A blockage in the central retinal vein can result in blurry or sudden loss of vision.
There are two types CRVOs:
-
Non-ischemic CRVO: This type of CRVO is not a symptom of an ischemic condition. The blood flow to the retina is only partially impeded and there is no damage to the retina.
-
Ischemic CRVO is: This type of CRVO is more severe and has a lower blood flow to the retina. This can lead to irreversible damage to the retina, and even more severe vision loss.
The most common cause of CRVO is a combination or combination of hypertension, diabetes, high blood cholesterol, and other medical conditions. These conditions can damage the blood vessels within the eye. This condition is more common in people over 65 and those with a history or cardiovascular disease.
The severity and extent of the damage to the retina will determine the treatment for CRVO. This may involve medications, laser therapy or surgery. It is crucial to have your vision checked by an eye doctor immediately in order to avoid further damage or vision loss.

What are the causes of Central Retinal Vein Occlusion?
Central retinal vein obstruction (CRVO), is usually caused by a combination factors. These factors include:
-
Blood clotting disorders: Conditions such as thrombophilia that increase blood clot risk can increase the likelihood of CRVO.
-
High blood pressure: Hypertension may cause damage to the blood vessels and increase the chance of developing CRVO.
-
Diabetes: High blood sugar can cause damage to the blood vessels and increase the chance of developing CRVO.
-
High cholesterol: Plaque buildup in blood vessels can lead to high cholesterol levels, which could increase the risk for CRVO.
-
Glaucoma: People with glaucoma (a condition that increases pressure in the eyes) may be at greater risk for developing CRVO.
-
Aging: CRVO occurs more frequently in older people, and the risk of developing it increases with age.
Although it may not be possible to pinpoint the exact cause of CRVO, there are usually a number of factors that damage blood vessels and increase the likelihood of obstructions or blockages in the central retinal vessel.
