Detection of Diabetic Retinopathy using Deep Learning: A Review

Abstract. Throughout the globe, 1.6 million people annually fall prey to dia- betes. And an alarming total of 422 million people throughout the world have been diagnosed with diabetes, most of the contribution to this number being from low and middleincome countries. Diabetic retinopathy is the number one cause of blindness in the world. It generally affects people from ages 25 to 65.It occurs when the blood vessels present in the retina get damaged by hyper - glycemia or prevents blood from passing through the eyes. It is crucial to treat diabetic retinopathy early. If left untreated, it eventually leads to blindness. The proposed methodology is to use Convolutional Neural Networks with ResNet inorder to diagnose diabetic retinopathy. Fundal cameras are used to obtain retinalimages. The aim is to detect and prevent this disease, where it is challenging to perform medical tests. As per the research study, the images will be prepro- cessed, segmented, enhanced, and then the extraction of features such as micro aneurysms and hemorrhages will occur. Based on this, the disease will be clas- sified into mild, moderate, severe, or proliferative. In the future, this model may also be used to detect other conditions, such as glaucoma and macular degener- ation.Published By: Blue Eyes Intelligence Engineering and Sciences Publication (BEIESP) © Copyright: All rights reserved
