Congenital perforated cornea in Peter's anomaly.

A male infant was born with a perforated left cornea associated with bilateral central corneal defects caused by mesodermal dysgenesis. Smears and culture of the perforated cornea revealed no infectious agents, and there was no evidence of systemic infection in the child or mother at birth. Histopathologic material excised during keratoplasty was compatible with persistent hyperplastic vitreous, possibly causing a forward displacement of the lens/iris diaphragm with pressure on the corneal endothelium and possible dissolution of the cornea leading to perforation. The relationship of increased intraocular pressure in this case was unknown.
