Retinal Vein Occlusion Treatment
Blood and nutrient circulation to and from the surface of the retina is mostly done through one vein and one artery. If these passages or any of the smaller branches connected to them are blocked, blood flow to the retina can become seriously disrupted. Blockage of one of these passages is known as occlusion, and can result in sudden vision loss.
The retinal vein carries blood away from the body, and may cause blood to build up and hemorrhage if it is blocked. Retinal vein occlusion, also known as venous stasis retinopathy, can also cause swelling, bleeding and growth of abnormal blood vessels which can in turn lead to other serious eye diseases.
This condition is most common in men and women over the age of 50, although the risk continues to increase with age. Other risk factors may include high blood pressure, high cholesterol, diabetes, smoking, glaucoma and, rarely, blood clotting and inflammatory conditions.
Although there is no cure for retinal vein occlusions, there are several treatment options available to help minimize risks, treat symptoms, and prevent further vision loss. The best treatment for each patient depends on the severity and location of the blocked vein, but may include laser photocoagulation or intraocular injections.
