Purpose: Ultrasound biomicroscopy (UBM) can be used to investigate the appearance of the anterior chamber in infants with congenital corneal opacity. This study investigated the association between the UBM-obtained clinical imaging of anterior chamber morphology and the clinical diagnosis in infants with congenital corneal opacity.
Subjects and methods: This study involved 19 eyes of 10 consecutive infants with congenital corneal opacity, 13 eyes with Peters anomaly (PA, 7 cases) and 6 eye with sclerocornea (SC, 3 cases), recruited at the Kyoto Prefectural University of Medicine, Kyoto, Japan between September 2001 and January 2009. In each subject eye, UBM findings were compared with the clinical diagnosis based on slit-lamp findings and intraocular pressure (IOP).
Results: UBM findings revealed partial angle closure in 10 PA eyes and in 5 SC eyes, absence of Descemet's membrane in 13 eyes and 6 eyes, and funicular fiber from the iris in 12 eyes and 6 eyes. All 6 eyes with SC showed normal IOP, while 9 eyes with PA were diagnosed as glaucoma.
Conclusion: Similarities in UBM appearance were observed between PA and SC. PA had a higher incidence of glaucoma; however, there was no relation between IOP and the UBM images.
