AIM:To investigate the clinical effect of lacrimal endoscope with canalicular incision for canaliculitis.

METHODS: A case-control study.Forty-three patients with canaliculitis were collected from September 2013 to October 2014 in our hospital. The patients were divided into case group with lacrimal endoscope with canalicular incision for 22 cases, and control group with canalicular concretion extruded and antibiotic injection within lacrimal canaliculi for 21 cases. The patients' 1a follow-up was carried out to observe the clinical effect of these two groups and to conduct statistical analysis.

RESULTS:The effective rate was 100% with 21 patients cured, one patient improved and no treatment failure for case group. The value was 71% with 10 patients cured, 5 patients improved and 6 treatment failure(surgical treatment)for control group. It had a better effective rate for canaliculitis treatment in case group, compared to control group. The difference was statistically significant(P<0.05).

CONCLUSION:The treatment of lacrimal endoscope with canalicular incision was minimally invasive, safe and effective for canaliculitis.
