Clinical Outcomes of Nasolacrimal Probing and Silicone Intubation in Patients with Congenital Nasolacrimal Duct Obstruction

ABSTRACT

PURPOSE: To investigate the efficacy and factors affecting the success rates of nasolacrimal probing and silicone intubation (SI) in patients with congenital nasolacrimal duct obstruction (CNLDO). METHODS: We retrospectively reviewed the medical records of patients including 69 eyes of 59 patients who received probing and 61 eyes of 49 patients who received SI. In patients with probing, the age, sex, and history of conservative treatment were analyzed in the success and failure groups, and a success rate comparison was conducted by dividing these values into postnatal group 1 ( 12 months, the success rate of probing was lower than in patients 12 months.
