Role of ultrasound biomicroscopy in managing pseudophakic pupillary block glaucoma.

We describe a case of anterior capsule adherence to the iris that occurred after phacoemulsification with in-the-bag intraocular lens (IOL) implantation. This adherence led to the development of pseudophakic pupillary block glaucoma. There were no synechias at the pupillary margin associated with the capsule-iris adherence. Ultrasound biomicroscopy, used to evaluate the anterior segment in vivo, clarified the mechanism of pseudophakic pupillary block. The pupillary block was relieved by a single laser iridotomy.
