Abstract: Diabetes is a condition where glucose level in the body is high. It is one of the prominent causes of retinal diseases. The survey done by the International Diabetes Federation (IDF) in 2017 states that, as of now 425million people on the earth are experiencing diabetes and that India is the second biggest nation [1]. People with diabetes may experience retinal disease such as Diabetic Retinopathy (DR), Diabetic Maculopathy (DM), etc. Knowing at the right time about these diseases and keeping the glucose level in the body properly helps in avoiding retinal diseases. DR is one of the retinal diseases found in diabetic patients which may lead to painless vision loss. Hard Exudates (HEs) are the accumulated fat formation in the retina leaked from damaged blood vessels of the retina and it is an early clinical sign of DR and DM. Thus, detection of HE at an early stage helps in preventing vision loss in patients. This survey paper gives a short presentation about the human eye, retina, diabetes and its complications. This paper also talks about the various methods/techniques that are used in automatic detection of hard exudates and the various issues involved in it.
Keywords: Hard Exudates (HEs), Fovea, Macula, Optic Disk, Diabetic Retinopathy (DR), Diabetic Maculopathy (DM).
