Silicone intubation of the lacrimal system: loop retraction as a complication.

Inadvertent retraction of silicone tubing after nasolacrimal intubation occurs with some frequency. This problem may be managed in sequential fashion with probing, dacryocystostomy or dacryocystorhinostomy depending on the needs of the patient at the time of occurrence and the original rationale for utilization of the technique.
