Two Cases of Congenital Lacrimal Fistula

Abstract

 We encountered two cases of unilateral congenital lacrimal fistula, both of which were treated surgically, and good outcomes were achieved. In one case, MRI was performed under sedation as part of preoperative assessment; however, it proved to be of limited value. Although no definitive treatment policy has been established for congenital lacrimal fistulas, the method of inserting a bougie into both the lacrimal fistula and the inferior lacrimal punctum is considered a useful surgical approach. This method facilitates the identification of the fistula's attachment site, thereby reducing the risk of injury to the lacrimal canaliculus.
