The Retina Is A Light-sensitive Membrane That Lines The Back Of The Eyes, And A Healthy Retina Is Vital To Normal Vision.

Leitgeb A, et al. In its most advanced stage, new abnormal blood vessels proliferate increase in number on the surface of the retina, which can lead to scarring and cell loss in the retina. Avastin, Lucentis, and Eylea vary in cost and in how often they need to be injected, so patients may wish to discuss these issues with an eye care professional. When fluid from blood vessels leaks into the macula, it can swell making vision blurry. Cataract also tends to develop at an earlier age in people with diabetes.

Symptoms can include: Sudden loss of vision in one or both eyes Retinopathy of prematurity — An ophthalmologist examines the inside of the eye for abnormalities. More severe vision loss can occur if the macula or large areas of the retina are detached.
