Glaucoma is an eye disease once it occurs, it cannot be cured. Be that as it may, in the event that it is starting stage doesn't take the therapeutic treatment its prompts the lasting visual impairment. Most of the literature surveys explain various techniques which are used with the help of the optic cup and optic disc to detect glaucoma. It tends to be successfully identified through the best possible segmentation of optic cup and optic disc. In this paper, we proposed about, NRR [neuro retinal rim] OTSU segmentation based technique. The disease will be confirmed by calculating the CDR [cup to disk ratio], RDR [rim to disk ratio], ISNT ratio [inferior, superior, nasal, temporal] and in analysis of glaucoma detection CDR and SVM [support vector machine] play the major role in identifying the glaucoma present or not. Our experimental technique has got the outcome of 94% accuracy.
