A case of neglected silicone tube in lacrimal duct for 20 years

Abstract

Purpose: To report a case of prolonged placement of a lacrimal silicone tube for 20 years, with evaluation of the lacrimal duct using lacrimal micro-endoscopy and inspection of deformation of the lacrimal tube. Observations: This study involved a case of dacryocystitis in which a silicone tube had been placed in the patient 20-years previous and that was treated conservatively. Although granulation tissue formation due to dacryocystitis in the lacrimal duct was observed under lacrimal micro-endoscopy, subjective and objective resolution of symptoms, including granulated tissue formation, was achieved after removal of the silicone tube and conservative medical treatment. Follow-up examinations performed over a 12-month period post treatment revealed no recurrence of epiphora or anatomical obstruction. Inspection of the lacrimal tube using the tension test revealed minimal changes in the tube in situ for 20 years. Conclusions and Importance: The findings in this case suggest both the lacrimal system and the silicone tube are tolerant to prolonged intubation, as long as the tube had been placed properly with careful observation. Our findings may encourage physicians to consider prolonged intubation for select cases of nasolacrimal duct obstruction.
