title: Congenital obstruction of the lacrimal passages in five consecutive generations.
abstract: Congenital epiphora due to absence or imperfection of lacrimal puncta and/or canaliculi was present in 21 members from five consecutive generations of a Sicilian family. The anomaly was transmitted as an autosomal-dominant characteristic with apparently complete penetrance and highly variable expressivity.
