Peter's anomaly: diagnosis by ultrasound biomicroscopy.

Author information

Department of Ophthalmology, New York Eye and Ear Infirmary, New York 10003, USA.


Peter's anomaly is a congenital corneal disorder characterized by a central leukoma and adhesions at the periphery of the corneal opacity. A 35-year-old man presented for clinical evaluation of suspected sclerocornea. High-resolution ultrasound biomicroscopy revealed iridocorneal adhesions throughout the anterior segment, a shallow anterior chamber, and abnormal hyper-reflectivity along the posterior corneal surface. Through ultrasound biomicroscopy, characteristics of Peter's anomaly were recognized, and a diagnosis was established. This case illustrates how ultrasound biomicroscopy aids in the clinical differentiation between Peter's anomaly and other causes of congenital corneal opacification.
