Computer Aided Diagnosis Methods for Classification of Diabetic Retinopathy Using Fundus Images

Diabetic Retinopathy is an eye disease, which can be commonly seen among the patients having diabetes. It is the significant cause of irreversible vision impairment. So, early detection is needed for the reduction of severe vision loss. Computer-Aided Diagnosis (CAD) method is required for large number of image screening to avoid the tedious process and the time consumption of the Ophthalmologist. In this paper, recently developed CAD techniques are analyzed with respect to performance evaluation and the challenges are discussed, some suitable solutions are suggested for improving the system to be more accurate.
