Automatic Detection & Segmentation Of Optic Disc In Retinal Eye

Large number of people suffers from eye diseases in rural and semi urban areas all over the world. Current diagnosis of retinal disease relies upon examining retinal fundus image using image processing. Glaucoma is a group of progressive optic neuropathies that have in common a slow progressive degeneration of retinal ganglion cells (RGC) and their axons, resulting in a distinct appearance to the optic nerve head (ONH), often called ¿cupping¿. This damage to the ONH causes partial to full loss of the visual field, which is the portion of space in which objects are simultaneously visible in the steadily fixating eye . Damage to the visual field is irreversible; however, the loss can be transitory in the early stages of glaucoma. If the condition is untreated the damage to the affected visual field usually worsens and spreads until eventually complete loss of vision can occur.
