This is the point at which the optic nerve enters the eye passing through the sclerotic membrane, the choroid layer, and finally the retina. The optic disc, a red disc found in the posterior pole, has a mean diameter between 2 x 1.5 mm. There are no photoreceptors in the optic disc, and for this reason it is also known as the blind spot.

Abstract
e-Ophthalmology is the use of information and telecommunications technologies to provide or support a group of activities related to ophthalmic care. Chronic glaucoma is an ocular disease characterized by optic neuropathy that leads to progressive loss of the visual fields and often is associated with elevated intraocular pressure levels. Glaucoma is an important public health problem because it is one of the main causes of blindness worldwide and generates an important demand for ophthalmologic consultations. The aim of this chapter is to discuss the application e-Ophthalmology-based models in the diagnosis and follow-up of chronic glaucoma. The authors describe the current status of the use of e-Ophthalmology-based models in the screening and follow-up of chronic glaucoma, the main advantages of these models, the technologic requirements for their implementation, and future trends in this field.
