Detection of Diabetic Maculopathy

The macula is an oval-shaped central part of the retina that controls the eye’s central vision. Macular degeneration caused by diabetes or age-related macular degeneration can result in blurry vision and even blindness. The macula of the eye is impacted by diabetes-related retinal degeneration known as diabetic macular edema (DME). That could cause serious issues or perhaps result in total blindness. Hence it is very important to understand and treat the problem early. Early detection of diabetic maculopathy (DM) is possible through regular checkups of diabetic patients but the availability of ophthalmologists is significantly less compared to the number of diabetic patients. It has created great interest in the automatic detection of diabetic maculopathy systems. In this paper, we have performed a review of different methods used in the detection of DM along with mentioning its pre-processing techniques and databases used. The results of each method are discussed.
