Ultrasound biomicroscopy in pupillary block glaucoma secondary to ophthalmic viscosurgical device remnants in the posterior chamber after anterior chamber phakic intraocular lens implantation.

摘要

A 25-year-old woman developed pupillary block glaucoma in the right eye after implantation of an angle-supported phakic intraocular lens despite a preexisting moderate-sized iridectomy. Ultrasound biomicroscopy (UBM) showed ophthalmic viscosurgical device retention in the posterior chamber and a full-thickness, patent-appearing iridectomy at 12 o'clock. The intraocular pressure gradually decreased to normal after a neodymium:YAG laser iridotomy was performed midperipherally at 9 o'clock. To our knowledge, this is the first report of UBM findings of this complication.
