Primary Open Angle Glaucoma (POAG)

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 topical drugs (eg, prostaglandin analogs, beta-blockers) and often requires laser or incisional surgery to increase aqueous drainage.
