Management of Prolapsed Silicone Tube Inserted for Treatment of Nasolacrimal Duct Obstruction

ABSTRACT

PURPOSE: To introduce a new surgical management for the prolapsed silicone tube into the ocular surface which was inserted for treatment of nasolacrimal duct obstruction. METHODS: Five eyes of 179 eyes treated with silicone tube intubation for nasolacrimal duct obstruction from May to December 2003 had a prolapsed silicone tube during the follow-up period. After local anesthesia, a Ritleng probe was inserted into the nasolacrimal duct. A polypropylene thread was passed into the Ritleng probe, and after removal of the probe, the thread was tied to a prolapsed silicone tube near a punctum and was pulled through the nose. The silicone tube was repositioned in the nasolacrimal duct. RESULTS: All the prolapsed silicone tubes were successfully repositioned without any significant complications. CONCLUSIONS: It is difficult to reposition a prolapsed silicone tube after silicone tube intubation for the treatment of nasolacrimal duct obstruction. We introduced an easy and effective method to reposition the prolapsed silicone tube.
