Abstract
Globally, glaucoma is the major cause of visual impairment. It is a chronic eye disease in which
optic nerve damages progressively due to the raised Intraocular Pressure (IOP) of the eye. The
technique proposed in this paper allows automatic detection of the glaucoma using digital
fundus image by extracting the features like vertical cup to disc ratio (CDR), its area ratio,
horizontal to vertical CDR and the ratio of area of blood vessels in inferior-superior region to that
in the nasal-temporal region of the Optic Disc (OD) (ISNT Ratio) by segmenting OD, cup and
