Chairman's Message Computer Made from Dna and Enzymes Glaucoma Classification from Optic Nerve Images

Glaucoma is one of the major causes of preventable blindness in the world. It induces nerve damage to the optic nerve head via increased pressure in the ocular fluid. It is presently detected either by regular inspection of the retina, measurement of the Intra Ocular Pressure (IOP) or by a loss of vision. It has been observed that nerve damage precedes the latter two events and that direct observation of the nerve head could therefore be a better method of detecting glaucoma, if the observations could be made reliably. This paper describes our work in enhancing and segmenting the optic nerve head in images of the retina and classification according to the severity of stages. Once glaucomatous disc is segmented its shape is compared with normal optic disc which reflects the severity of the nerve damage. Finally once the nerve head has been located, the shape will be quantified and stored as a feature vector for further analysis.
