Diabetes is the term most commonly referred to diabetes mellitus. DM is a condition in which the body is not able to
satisfactorily process ingested sugar. Diabetic Retinopathy (DR) is a disorder of the retina resulting vision loss. It is usually due
to damage to the blood vessels of the retina, occurring (for example) as a complication of diabetes (diabetic retinopathy) or high
blood pressure. For the analysis and detection of DR retinal fundus images are commonly used. Therefore, to detect these retinal
abnormalities such as blood vessels, exudates, haemorrhages, microaneurysms automatic detection systems are used. So the
automated analysis of the fundus image is an important task which will be helpful for the doctors to analyse any sectional
blindness or thorough blindness. The objective is to present briefly various works in segmenting and detecting different lesions
occurring in diabetic retinopathy patients. In this paper, we present a review for the detection of diabetic retinopathy from retinal.
