Diabetic retinopathy (DR) is a complication that causes changes in blood vessels present in the retina, which leads to vision loss at later stages, and has no or lesser symptoms during the initial stages. Diabetic patients present around the globe are prone to DR, and it is one of the leading causes of vision loss. Various intelligent systems are continuously evolving to assist ophthalmologists in identifying the retinal abnormalities. In this research, recent computer-aided diagnosis (CAD) systems are analyzed based on the nature of data, recent approaches taken in classifying DR, performance comparison using statistical parameters, existing limitations, and challenges. The comparison results indicate that developing a precise CAD system in identifying DR is still an open research problem. The objective of this research is to survey recent research works, identify the gap, and provide useful insights that would help researchers working in this field to develop more efficient CAD systems.
