title: Pigmented pupillary pseudomembranes as a complication of argon laser iridotomy.
abstract: Two cases are reported in which pupillary pigment occlusion occurred after argon laser iridotomy, reducing visual acuity and preventing fundus visualization. Laser-induced inflammation and subsequent long-term miotic therapy are probably responsible for this complication. Periodic pupillary dilatation is recommended in eyes that require miotics to control their intraocular pressure after laser iridotomy.
