Congenital Lacrimal Fistula in a Seven-Year-Old Female: A Rare Cause of Epiphora

Abstract

Congenital lacrimal fistulas are rare epithelium-lined tracts that tend to have a direct communication between skin and the lacrimal drainage system. These are benign developmental abnormalities, that may require no treatment. This is a rare diagnosis since patients are usually asymptomatic and presents only when epiphora is associated. When symptomatic, congenital lacrimal fistula presents as epiphora, or mucoid discharge, rarely patients could develop nasolacrimal duct obstruction, which may present as recurrent dacryocystitis. Thorough clinical examination is the best way to diagnose the condition, where a fistula ostium may be found inferonasal to medial canthus of the eye. Further, lacrimal probing and irrigation is helpful. Surgical management of the fistula is advised only if the disease is symptomatic which ranges from simple excision to dacryocystorhinostomy. This is a report of one such patient with congenital lacrimal fistula which was treated surgically by fistulectomy.
