Diabetes and the Eye
Damaged eye blood vessels may leak fluid into the retina. The retina swells (edema) and vision may be affected. Sometimes changes may resolve spontaneously and leave no permanent damage. At other times changes tend to progress and must be treated by retina subspecialists. Treatment is very important because it reduces additional visual loss.
When microscopic blood vessels over large areas of the retina are severely damaged the eye tries to compensate by inducing remaining blood vessels to multiply (“Neovascularization” – a form of “Proliferative Diabetic Retinopathy”). The new blood vessels are abnormal and are not helpful. Some types, if left untreated, may rupture and cause bleeding inside the eye with severe visual loss.
