Automated Diagnosis of Glaucoma Using Cup to Disc Ratio

Image processing does the operations to get the enhanced image that will extract useful information. Glaucoma is one of the leading sources of irreversible blindness in people above 40 years old.It is an Eye disease also known as “Sneak thief of sight” caused when the IOP(Intra Ocular Pressure) of the Aqueous Humor fluid present in between Iris, Lens and Cornea, Iris increases. This fluid is produced and drained at the same rate by maintaining the constant Intra Ocular Pressure (IOP) at 16mm Hg. The IOP of the Aqueous Humor increases due to any block in the canal of schlemm, because of this increase in pressure of Optic Nerve and retina are compressed. This paper proposes a computational tool for detecting Glaucoma automatically.
