Abstract:
Previously reported cases of lacrimal outflow dysgenesis have frequently been associated with developmental anomalies or systemic syndromes, raising potential red flags in affected children. We report an unusual case of familial punctal atresia with apparent genetic linkage to bilateral preauricular sinuses without any such comorbid syndromic features.
