Effect of endoscopic canaliculus opening operation for proximal lacrimal duct obstruction / 国际眼科杂志(Guoji Yanke Zazhi)

ABSTRACT

@#AIM: To investigate the feasibility, effect and safety of endoscopic canaliculus opening operation with lacrimal drainage tube for proximal lacrimal duct obstruction.<p>METHODS: Totally 52 patients(61 eyes)with proximal lacrimal duct obstruction were examined in the Third Affiliated Hospital of Nanchang University from June 1 2016 to June 1 2018, and all were treated by endoscopic canaliculus opening operation with lacrimal drainage tube. Lacrimal drainage tube was removed after 2-3mo. All patients were followed up from 6-12(mean 7.3±2.2)mo. The operation effect and complications were observed.<p>RESULTS: All patients were treated by endoscopic canaliculus opening operation with lacrimal drainage tube successfully. The recovery rate was 85%, improvement rate was 8%, ineffective rate was 7%, effective rate was 93%. Without serious complications occurred after operation.<p>CONCLUSION: Endoscopic canaliculus opening operation with lacrimal drainage tube for treating the proximal lacrimal duct obstruction, could locate precisely and fully open the normal lacrimal duct with high success rate, safe and feasible.
