摘要：Diabetic retinopathy (DR) and glaucoma are the commonest complications of diabetes and is one of the leading causes ofblindness. Early detection of occurrence of DR can greatly help in effective treatments. Very effective treatments are available and areoptimally used when retinopathy is detected early. For this reason screening programs for early detection of retinopathy is essential part.The retinal fundus photographs are the main resources for screening of DR. In this work we tried to locate the eye optic disc and optic cupusing k-means algorithm, morphological operation and watershed transform. Segmented optic disc and cup are then used to compute thecup to disc ratio for DR screening, for grading the disease we use micro aneurysms. Micro aneurysms are the clinical sign of DR theyappear small red dots on retinal fundus images, their detection can be used to grade the DR in different stages
