Retinal Vein Occlusion is a medical condition in which blood vessels usually suffer from occlusion causing severe impairment to the retina and blindness in severe cases. A patient with Retinal vein occlusion suffers from an obstruction of the veins responsible for carrying blood away from the retina. Retina is basically is a layer of tissue at the back of the inner eye that transfigures light images to nerve signals and sends them to the brain. There are many risk factors involved with this disease such as Atherosclerosis, Diabetes and High blood pressure (hypertension). In very severe cases it can also cause other eye conditions, such as glaucoma, macular edema (leakage of fluid in the retina), or vitreous hemorrhage.

This sort of disease is really bad for the eyes and can cause major deterioration if not diagnosed and treated in time.

Treatment

Many people will regain vision, even without treatment. However, vision rarely returns to normal. There is no way to reverse or open the blockage.

You may need treatment to prevent another blockage from forming in the same or the other eye.

It's important to manage diabetes, high blood pressure, and high cholesterol levels. Some patients may receive aspirin (http://www.ncbi.nlm.nih.gov/pubmedhealth/PMH0000802/) or other blood thinners.
Treatment for the complications of retinal vein occlusion may include:


Focal laser treatment, if macular edema is present
Injections of anti-vascular endothelial growth factor (anti-VEGF) drugs into the eye. These drugs may block the growth of new blood vessels that can cause glaucoma. This treatment is still being studied.
Laser treatment to prevent the growth of new, abnormal blood vessels that leads to glaucoma

Expectations (prognosis)

The outcome varies. Patients with retinal vein occlusion often regain useful vision.

It is important to properly manage complications, such as macular edema and glaucoma. However, having either of these complications is more likely to lead to a poor outcome.

Complications


Glaucoma
Partial or complete vision loss in the affected eye

Calling your health care provider

Call your health care provider if you have sudden blurring or vision loss.

Prevention

Retinal vein occlusion is a sign of a general blood vessel (vascular) disease. The same measures used to prevent other blood vessel diseases, such as coronary artery disease (http://www.ncbi.nlm.nih.gov/pubmedhealth/n/pmh_adam/A007115/), may decrease the risk of retinal vein occlusion.

These measures include:


Eating a low-fat diet
Getting regular exercise
Maintaining an ideal weight
Not smoking

Aspirin (http://www.ncbi.nlm.nih.gov/pubmedhealth/PMH0000802/) or other blood thinners may help prevent blockages in the other eye.
Controlling diabetes is important in general, and it may also be helpful for preventing retinal vein occlusion.
