Advances in computerised image analysis and retinal imaging modalities have significantly contributed towards the growth of image-based diagnosis. Glaucoma is an ocular disorder which results in irreversible vision loss. The progression of glaucoma is quiet and in early stages does not show any symptoms. Vision loss due to glaucoma has been significantly increasing compared to other retinal disorders. The reliability in diagnosis of glaucoma is limited to the experience and domain knowledge of the ophthalmologist. A computer-based diagnostic system can be developed using image processing algorithms for screening large population at less cost, reducing human errors and thus making the diagnosis more objective. A review of the state-of-art methodologies employed for developing a computer aided diagnosis of glaucoma using retinal fundus image is addressed in this paper along with the future trends.
