Chapter 1: Introduction to Glaucoma: Terminology, Epidemiology, and Genetics
The term glaucoma refers to a group of optic neuropathies characterized by optic disc excavation, or cupping, and corresponding patterns of vision loss.
Glaucomas are classified by age of onset (childhood vs adult onset), etiology (primary vs secondary), and gonioscopic assessment of the iridocorneal angle (open vs closed).
Elevated intraocular pressure (IOP) is a major risk factor for glaucoma; however, a large proportion of patients with primary open-angle glaucoma have IOP in the statistically normal range.
Glaucoma is a major public health problem and is the leading cause of irreversible blindness worldwide.
Many genes and genomic regions have been found to be associated with various types of glaucoma.
