Alagille's syndrome or arteriohepatic dysplasia is a unique and uncommon congenital disorder exhibiting a combination of systemic and ocular abnormalities. It is of interest to the ophthalmologist presenting with a combination of anterior and posterior segment anomalies and it is unique for the paediatrician in that these anomalies distinguish this condition from all other causes of neonatal jaundice. The authors describe a case of a young girl with Alagille's syndrome who developed bilateral acute angle closure, a hitherto unreported finding in this condition.
