Acetazolamide –friend to foe

Abstract

Bilateral acute angle closure attacks are rare and usually secondary to drugs or concurrent microspherophakia. Acetazolamide, a sulphonamide medication used in controlling intraocular pressure, is known to cause uveal effusion precipitating secondary acute angle closure attack. Here we report a well-documented case of concurrent bilateral angle closure with shallowing of the anterior chamber, supra-ciliary effusion, and serous and hemorrhagic choroidal detachment after administration of oral acetazolamide that resolved on withdrawing the insulting agent.
