Glaucoma Detection Using Optic Cup and Optic Disc Segmentation

Abstract — Glaucoma is a chronic eye disease. In Glaucoma the optic nerve head is progressively damaged. It is very important to detect Glaucoma disease in time, because it can be cured and it leads to permanent vision loss. In this paper, optic cup and optic disc segmentation is used for assessment of optic nerve head. Segmentation is based on superpixel classification. It consists of optic disc and optic cup segmentation based on superpixel classification. For optic disc and optic cup segmentation adaptive histogram equalization and Gabor filter are used basically for classifying each superpixel as disc or non disc Finally Cup to disc ratio CDR is evaluated and compared with threshold value for detection of glaucoma
