Diabetic retinopathy (DR) is a condition that occurs in individuals who have diabetes. It makes gradual damage to the retina, the light-sensitive lining at the back of the eye. Diabetic retinopathy is a serious sight- threatening complication of diabetes. DR is the main reason of loss vision in people if not detected and treated in time. Computer Aided Diagnosis (CAD) system helps to identify Diabetic retinopathy in fundus images. In this paper we discuss and review about various techniques to find nonproliferative and proliferative Diabetic retinopathy diseases. The paper also focuses on qualitative and quantitative comparison of the existing literature with limitation in order to develop a better and more effective method. It is an attempt to gathering the available algorithms for future research.
