Treatment of retinal vein occlusions
The most important things that you can do to reduce the risk of developing retinal vein occlusions is to control the glucose level and blood pressure level as well as possible with the assistance of your primary care physician. If a retinal vein occlusion develops and fluid collects at the central retina (macular edema), the current treatment is to inject anti-VEGF medications into the eye and (Avastin®, Lucentis® and Eylea®). This helps to stabilize blood vessels and reduce leakage of the blood vessels. After several injections, the fluid often improves. The amount of visual improvement, however, depends on the degree to which the retina had been damaged during the initial vein occlusion. Sometimes, injections are required for several years depending on the health and stability of the damaged blood vessels.
Occasionally, abnormal blood vessels develop and this may need to be treated with laser treatment. Less commonly, new blood vessels can grow in the front of the eye and cause very severe glaucoma. As such, it is important that the eyes be checked regularly by a retina specialist to be sure that the retina has stabilized and does not require additional treatment.
