AB  - Diabetic Retinopathy (DR) is characterized by the progressive deterioration of retina with the appearance of different types of lesions, which includes microaneurysms, hemorrhages, exudates etc. Early detection of lesions plays a significant role in the diagnosis of DR. This paper analyses different methods for the automatic detection of lesions in the screening of DR. Automated lesion detection scheme mainly consists of four steps: vessel extraction and optic disc removal, pre-processing, candidate lesion detection and post processing. The paper gives a survey about the different methods that can be used in the screening of diabetic retinopathy.
