Abstract: Diabetic Retinopathy (DR) is a medical condition which affects the normal vision of a human. Patients having long history of diabetes tend to be affected by DR. An increased level of blood sugar may lead to an eye disease termed as DR. Early detection of DR helps the ophthalmologists to advise proper treatment to save the vision of the patient. In this paper, a survey has been carried out and different techniques are discussed to extract different features. Exudates, Microaneurysms and abnormal growth of blood vessels are some of the symptoms of DR. Preprocessing of an image is always required to obtain a contrast enhanced image. The paper provides overview of some of the preprocessing techniques used till now and different methods to extract exudates, microaneurysms and blood vessels are discussed.
