The surgical management of congenital lacrimal fistulae.

Congenital lacrimal fistulae are developmental anomalies of the lacrimal apparatus that are usually symptomatic, frequently causing epiphora and occasionally causing fistulitis or dacryocystitis. They may be associated with other abnormalities of the lacrimal system or with systemic anomalies. Complete excision alone, or in combination with nasolacrimal intubation and/or dacryocystorhinostomy is recommended for treatment.
