Secondary acute angle closure glaucoma: a complication of AIDS.

A 58-year-old man with advanced AIDS presented to the emergency department complaining of headache and decreased vision bilaterally. On evaluation, he was found to have intraocular pressures of 69 and 65 mm Hg. After topical treatment with miotics and apraclonidine, he was given intravenous acetazolamide (Diamox) and peripheral iridotomy was performed. The pressures did not improve significantly. Secondary acute angle closure glaucoma was diagnosed. Emergency physicians should consider this diagnosis when evaluating AIDS patients with visual complaints.
