An Approach to Locate Optic Disc in Retinal Images with Pathological Changes

The detection of retinal structure is an important prerequisite to diagnose retinal diseases automatically. The retina contains several important structures, such as optic disc (OD), fovea, and vessels. Optic disc is the region where blood vessels and optic nerves converge. There are no light-sensing cells in OD area, so optic disc is also called blind spot. In the normal retinal images, OD is the brightest part and looks like a pale, nearly circular or vertically slightly oval disk. Correct OD detection is the basic step for computer aided diagnosis of different eye diseases, such as diabetic retinopathy [1] and glaucoma [2].
