Acute angle-closure glaucoma due to iris transfixation of a subluxated posterior chamber intraocular lens–capsular bag complex

Abstract

An 80-year-old woman with pseudoexfoliation syndrome developed subluxation of a posterior chamber intraocular lens (IOL)-capsular bag complex due to zonular rupture. She underwent a limited 25-gauge pars plana vitrectomy and iris transfixation of the subluxated IOL-capsule complex. The postoperative course was uneventful until the patient developed acute angle-closure glaucoma 3 weeks postoperatively. Ultrasound biomicroscopy confirmed pupillary block by the IOL-capsule complex. The patient was treated with intraocular pressure-lowering medications and a vitreous tap before a laser peripheral iridotomy could be performed successfully. The vision returned to normal, and the angle closure resolved. We recommend that a prophylactic surgical iridectomy be performed in patients with iris transfixation of a posterior chamber IOL-capsular bag complex.
