Analysis of Diabetic Retinopathy in Retinal Fundus Images

Past few decades one of the most concerning issues in the current health care sector is progression of diabetes. The most common complication of diabetes is Diabetic Retinopathy (DR), which is one of the leading causes of blindness or vision loss in people. This paper aims to analyze diabetic retinopathy in retinal fundus images. Initially Pre-processing of the fundus image is performed. Then to detect the optic disc Principal Component Analysis (PCA) is used. Also morphological operations are carried out to determine the micro aneurysm in the fundus images. The performance analysis is carried out using Eigen value, variance. The results show performance is better in detection of the optic disc.
