Congenital ectropion uveae with glaucoma.

Abstract

Congenital ectropion uveae (CEU) is a rare, nonprogressive anomaly characterized by the presence of iris pigment epithelium on the anterior surface of the iris stroma, often associated with neurofibromatosis and occasionally with other ocular anomalies. We present eight patients with unilateral CEU. Seven patients had glaucoma in the involved eye, while the eighth was a 10-week-old infant. In the two patients with bilateral glaucoma, the second eye was similar to the first, but without CEU. Three patients had neurofibromatosis, two had facial hemihypertrophy, one had Rieger's anomaly, one had Prader-Willi syndrome, and one had no systemic anomalies. Two had initially been misdiagnosed as having a large pupil in the involved eye and one as having a Horner's syndrome in the uninvolved eye. The finding of CEU in an infant warrants continued observation for the development of glaucoma and disorders of neural crest origin.
