Clustering Based Approach for Segmentation of Optic Cup and Optic Disc for Detection of Glaucoma

Glaucoma is a disease in which damage of the optic nerve of eye leads to progressive and irreversible vision loss. It is caused due to enlargement of the optic cup present inside the optic disc. It can be detected by calculating the CDR value which is the ratio of segmented optic cup to the segmented optic disc. Optic disc is the point from where various ganglion cells exit from eye to form an optic nerve. On the other hand, optic cup is a depression of the variable size present inside the optic disc. This paper initially presents a review analysis of existing techniques followed by a novel approach with improved accuracy.
