Pupillary Block, Angle-closure Glaucoma Produced by an Anterior Chamber Air Bubble in a Nanophthalmic Eye

Arch Ophthalmol. 1996;114(9):1145-1146. doi:10.1001/archopht.1996.01100140347021

Acute angle-closure glaucoma is a real ophthalmic emergency that requires prompt therapy. Pupillary block is the most common mechanism leading to acute angle-closure glaucoma, and it occurs when the flow of aqueous humor from the posterior chamber to the anterior chamber is obstructed by a functional block between the pupillary portion of the iris and the lens. The flow of aqueous humor through the pupillary aperture can be impeded in several ways.1 We report a unique case of acute pupillary block, angle-closure glaucoma that developed secondary to an air bubble, which was occluding the pupillary aperture.

Report of a Case.  A 65-year-old Hispanic woman, who had nanophthalmos, underwent cataract extraction via phacoemulsification; the procedure was complicated by a small tear in the Descemet membrane. At the end of the procedure, a large air bubble was infused into the anterior chamber to unfold the tear and prevent its extension.Eight
