Abstract

1 Introduction</h5> Application of noninvasive techniques in automatic retina analysis is an important area in medicine [1] . The information extracted from the analysis of digital images can be used to determine the existence of ocular diseases, such as glaucoma [2] .</P>The optic disc (or optic papilla) yields the clearest area in images of the rear pole of the retina. Anatomically in a normal papilla, the vascular network emerges from the choroids through the center of the nervous fibers that constitute the optic nerve. In turn, the optic nerve passes through a tube-like structure toward the brain. Glaucoma, an ocular asymptomatic neuropathy, creates excessive intraocular pressure and an increase in size of the excavation (or cup) in the papilla. This excavation produces a thickening of the wall of the papilla, which then pushes the blood vessels (arterial and venous) located within the optic disc boundary (called also the vascular bundle ) toward the nasal side of the affected eye(s). In time, the increased size of the cup and the displacement of the vascular bundle, damages the optic nerve. If left untreated, glaucoma causes first a progressive irreversible loss of peripheral vision and finally leads to blindness. Glaucoma occurs
