Computerized macular edema detection using OCT images: A review

This article reviews the existing approaches that are used for computerized detection of Macular Edema (ME), which is one of the leading causes of blindness among majority. It takes place when there is unusual leakage and accumulation of fluid inside the macula from broken blood vessels within the nearby retina. Any disorder that damages blood vessels inside retina can reason. The signs of ME are not apparent in the early stages and it is difficult to diagnose at its advanced stages. Optical coherence tomography (OCT) is the modern day eye exam approach which gives cross sectional location of retinal layers, and can be utilized for the earlier detection of ME. Different algorithms were implemented to detect ME from OCT images. This article focuses on identifying a computerized algorithm that could detect ME at earlier stages with great level of accuracy.
