AIM: To evaluate the surgery skill and efficacy of retrograde lacrimal intubation on treatment of chronic dacryocystitis with nasal endoscopic.

METHODS: Totally 45 patients(52 eyes)with chronic dacryocystitis in this study received retrograde lacrimal intubation by nasal endoscopic, and the tube was removed after placing 2-3 months. The efficacy was observed after surgery.

RESULTS: All operations on the patients were conducted successfully, and no serious complications during and after surgery. 41 eyes(79%)were cured, 4 eyes(8%)were improved and 7 eyes(13%)had no effective improvement. The effective rate was 87%.

CONCLUSION: Retrograde lacrimal intubation on treatment of chronic dacryocystitis with nasal endoscopic can make the surgery safer, easier and less injury.
