Pediatric Canaliculitis and Stone Formation

Abstract

A 5-year-old girl with a remote history of idiopathic thrombocytopenic purpura presented with a history of partial nasolacrimal duct obstruction unresolved with standard treatments of probing, irrigation, and lacrimal system intubation. Surgical exploration revealed canaliculitis with dacryolith formation within the inferior canalicular system. After punctoplasty and removal of the dacryoliths, the patient had full resolution of symptoms. Although the diagnosis is uncommon in this age group, it should be included in the differential diagnosis of chronic or recurrent pediatric nasolacrimal obstruction.
