Treatment of Diabetic Retinopathy

There are two types of Diabetic Retinopathy: Nonproliferative Diabetic Retinopathy (NPDR) and Proliferative Diabetic Retinopathy (PDR). NPDR, commonly known as Background Retinopathy, is an early stage of Diabetic Retinopathy. In this stage, tiny blood vessels within the retina leak blood or fluid. The leaking fluid causes the retina to swell or to form deposits called exudates. Many people with diabetes have mild NPDR, which usually does not affect their vision. When vision is affected it is the result of Macular Edema and/or Macular Ischemia.
