I. Introduction
Diabetic Retinopathy (DR) is an optical retinal symptom affected with rich blood sugar levels. The retina absorbs energy from the blood vessels. Diabetic Retinopathy develops when blood sugar (glucose) levels rise. This will choke the small vessels which serve to cutoff the retina’s blood circulation [28] and eyes try to grow fresh blood vessels, which will not mature properly and will tend to degrade. Classifying Diabetic Retinopathy into two different types first one is non-proliferative [28] (NPDR) and second one is Proliferative [25] (PDR), Non-proliferative [28] (NPDR) syndrome is distinguished by lesions in the early stages. Proliferative (PDR) syndrome is recognized by the neovascularization of thin blood vessels.
