Survey on Detection of Various Retinal Manifestations of Eye

Identification of retinal diseases using various techniques is a very important area of ophthalmology. Traditional methods are highly subjective which are based on manual observation and highly prone to error. So, it is very essential to establish an automatic system for screening vision threatening diseases like diabetic retinopathy and others for huge number of people. Now days, image processing has become a very effective tool for the automated detection of abnormalities in retinal images. In this paper, the basic terminology related to automatic detection of various retinal manifestations is discussed. It also describes the steps required for automatic detection as well as the techniques used to implement these steps in recent years.
