A case of bilateral lacrimal fistula associated with Down syndrome.

INTRODUCTION: Congenital lacrimal fistulae are a developmental disorder and can be associated with other hereditary developmental diseases. CASE REPORT: A patient with Down syndrome presented with events of recurrent dacryocystitis and lacrimal fistulation on 1 eye. A DCR surgery with excision of a fistula had been performed 2 years before. The investigation under general anesthesia also revealed a clinically unrecognized lacrimal fistula on the contralateral side. COMMENT: The case report documents a unique case of bilateral congenital lacrimal fistulae in association with Down syndrome. Dacryocystitis in patients with Down syndrome could result from a congenital lacrimal fistula.
