Background and objective: Glaucoma is a ocular disorder which causes irreversible damage to the retinal nerve fibers. The diagnosis of glaucoma is important as it may help to slow down the progression. The available clinica methods and imaging techniques are manual and require skilled supervision. ...
Glaucoma is a neuro-degenerative disorder of the eye and it leads to permanent blindness when untreated or detected in the later stage. The main cause of glaucoma is the damage of the optic nerve, which occurs due to the increase of eye pressure. Hence the early detection of this disease ...
Chapter 7 Glaucoma 135 136 C H A P T E R 7 "Glaucoma" is a generic term for a common group of ocular diseases which, if untreated, can result in an irre- versible loss of visual function. An inappropriate intraocular pressure linked to damage to the neuronal tissue in the optic nerve...

Introduction Childhood glaucoma is a relatively rare but potentially blinding eye disorder characterized by elevated intraocular pressure (IOP) and optic nerve damage, which can be caused by a diverse group of conditions.1 Five in 100 000 children born in Great Britain each year are diagnosed as...
a slow loss of peripheral vision in one or typically both eyes eventually leads to loss of central vision. Because of this loss pattern, affected persons do not notice a change in their vision until their loss is advanced and affects the central vision, in which case damage is permanent and...
A rare genetic disorder that usually manifests itself at birth or within the first year of life, but may emerge up to the age of 3. Glaucoma A multifactorial optic disk neuropathy with a complex genetic basis, in which there is a characteristic acquired loss of retinal ganglion cells and at...
Glaucoma is a neurodegenerative disorder characterized by the progressive functional impairment and degeneration of the retinal ganglion cells (RGCs) and their axons, and is the leading cause of irreversible blindness worldwide. Current management of glaucoma is based on reduction of high intraocular pre...
Thus proper segmentation of optic disk and optic cup plays an important role in detecting the disorder. In this paper an adaptive threshold based method which is independent of image quality and invariant to noise is used to segment optic disk, optic cup, Neuroretinal rim and cup to disk ...
