Bilateral congenital lacrimal fistulae: a case report.

A congenital lacrimal fistula is a rare developmental anomaly, usually unilateral. While it is often asymptomatic, some patients present with epiphora or discharge. We report the case of a 4-year-old boy with bilateral lacrimal fistulae. No other systemic, nasal, or ocular anomalies were found. In the absence of significant symptoms, we decided on a course of observation. In this article, we discuss the embryologic basis of congenital lacrimal fistulae, as well as the typical presentation and possible treatment modalities. The presence of a lacrimal fistula is an indication to search for a variety of underlying systemic and ocular anomalies.
