Optical iridectomy for corneal opacities in Peter's anomaly.

摘要

Three children were born with partial corneal opacity and anterior segment anomalies but no cataract (Peter's anomaly type 1). In each affected eye, the corneal scar was off center and encroached on the visual axis. Glaucoma (if present) was controlled medically or surgically, after which an optical iridectomy was performed in each eye (in lieu of a penetrating keratoplasty). After surgery, in all patients the pupil extended beyond the corneal opacity and the corneal opacity decreased slightly. All could fixate and follow around the opacity. Optical iridectomy should be considered in selected cases of congenital corneal opacities.
