摘要：A Portion of optic nerve that is visible in the retinal fundus is called the optic disc (OD).Optic disc is one of the vital information in detecting the diseases in the retina by implementing an image processing algorithm. Algorithm focuses on the properties and the characteristics of the optic disc. Optic disc has got its own shape, color, size and intensity used to detect it in the retinal images. The optic disc is the entrance of the optic nerve and the vessels in the retina called blind spot. Blind spot in the retina has the cone cells, rod cells which captures the impulses and convert them into proper images and carry them to the brain. Detection of optic disc is useful in diagnosing the pressure within the skull that causes this disc to bulge forward. The pressure within the eye squeezes off the blood supply, and reduced blood supply starves the retina from nourishment, and ultimately the nerve cells start to die - glaucoma. A novel approach is proposed to investigate the screening performance on the glaucoma disease, and to differentiate the normal and glaucomatous eyes, this screening system is designed. With Cup to disc ratio (C/D), the classification among the normal and the glaucomatous images was found. When the cup to disc is greater than 0.3 (cup to disc> 0.3mm), it is considered as the glaucoma affected eye.
