Optic disk segmentation using superpixel classification

Glaucoma is a chronic eye disease in which the optic disc becomes progressively cupped, as axons die off. Curiously, this is the only optic nerve disorder in which severe cupping takes place. Vision loss takes place due to progression of the disease. Very few signs or symptoms are present in progression of disease and the vision loss from glaucoma is irreversible. Detecting the disease in time is important, as it cannot be cured. Current tests using intraocular pressure (IOP) are not sensitive enough for population based glaucoma screening. A more promising and superior method for glaucoma detection than other current methods is Optic nerve head assessment in retinal fundus images. Optic nerve head assessment can be done by a trained professional. However, manual assessment is subjective, time consuming and expensive. Therefore, automatic optic nerve head assessment would be very beneficial.
