Review Article


There are two types of clinical signs of diabetic retinopathy: red lesions and bright lesions. Red lesions which include microaneurysms are early signs of diabetic retinopathy. Microaneurysms are clinically important initial qualities of retinopathy. Their number increases with the severity of retinopathy. Hemorrhages are also signs of diabetic retinopathy which appear after microaneurysms. This work has concentrated on the review of the development of several techniques to automate the detection and classification of suggestive features of red lesions of first retinopathy progress.


Microaneurysms Hemorrhages Red lesions Diabetic retinopathy 



The authors would like to express their deep sense of gratitude to Dr. Sonal A. Jain, Saraswati Skin and Eye Care Centre, Mumbai, for providing guidance on red lesions in fundus images.
