[Keratoconus in Alagille syndrome].

We report on a 20 year old white male with growth retardation, secondary hypothyroidism, typical facies, skin lichenification and brachydactylia due to arteriohepatic dysplasia. We found a bilateral keratoconus with corneal scaring but none of the other known ophthalmological findings. A keratoplasty was performed in the right eye. The pathogenesis of the keratoconus is unknown.
