Clinical observation of the treatment for chronic dacryocystitis under lacrimal endoscope

AIM:To evaluate the clinical efficacy of lacrimal dredge under lacrimal endoscope for treating chronic dacryocystitis. METHODS: Sixty patients(64 eyes)with chronic dacryocystitis were examined and treated by lacrimal endoscope combined with full lacrimal intubation. All patients were followed up for 3-6 months postoperatively. RESULTS: Forty-five eyes of 64 eyes were cured, no tears, irrigation of lacrimal passage unobstructed. Thirteen eyes get partly recover, but there were still mild overflow tears, and although lacrimal passages can be flushed, but there were still partly lacrimal duct obstruction. The rest 6 eyes were invalid and still tears, irrigation of lacrimal passage obstructed. The total effective rate was 90.6%. CONCLUSION: The diagnosis and treatment of nasolacrimal duct obstruction under lacrimal endoscope is a safe and effective way.
