Primary Open Angle Glaucoma
Introduction
Primary open-angle glaucoma is a syndrome of optic nerve damage associated with an open anterior chamber angle and an elevated or sometimes average intraocular pressure (IOP). Symptoms are a result of visual field loss. Diagnosis is by ophthalmoscopy, gonioscopy, visual field examination, and measurement of central corneal thickness and IOP. Treatment includes laser surgery and/or topical medications (eg, prostaglandin analogs, beta-blockers) and often requires incisional surgery to increase aqueous drainage.
