Angle Closure Glaucoma
Introduction
Angle-closure glaucoma is glaucoma associated with a physically obstructed anterior chamber angle, which may be chronic or, rarely, acute. Symptoms of acute angle closure are severe ocular pain and redness, decreased vision, colored halos around lights, headache, nausea, and vomiting. Intraocular pressure (IOP) is elevated. Immediate treatment of the acute condition with multiple topical and systemic medications is required to prevent permanent vision loss, followed by the definitive treatment, iridotomy. (See also Overview of Glaucoma .) Angle-closure glaucoma accounts for about 10% of all glaucomas in the United States.
