AIM: To evaluate the safety and efficacy of retrograde lacrimal intubation for treatment of nasolacrimal duct obstruction.

METHODS: This study included 92 patients(106 eyes)with nasal lacrimal duct obstruction from August 2010 to February 2011. Retrograde intubation was performed with local anesthesia for all cases, and, the tube was removed after 3-6 months. Then, the patients were followed up for 12-18 months.

RESULTS: The intubation was successful in all eyes, and the tubes were removed conventionally at 3-6 months. Among them 84 patients(97 eyes)were unobstructed when the tubes were removed, and the effective rate was 91.5%.

CONCLUSION: Retrograde lacrimal intubation is safe, minimal invasion, effective, less bleeding and good efficacy, is an effective way to cure nasolacrimal duct obstruction.
