AIM: To investigate the independent influencing factors of endoscopic dacryocystorhinostomy in the treatment of lacrimal duct diseases.

METHODS: Retrospectively analysis of the cases of 280 patients(316 eyes)with lacrimal duct diseases treated by endoscopic dacryocystorhinostomy in Hankou Eye Hospital of Wuhan Aier from Oct. 2015 to Mar. 2019, summarizd the efficacy and analyzed the independent factors of efficacy by using the ordered Logistic regression.

RESULTS: The total cure rate was 52.2%, the total improvement rate was 30.7%, and the total invalid rate was 17.1%. Rhinitis(OR=95.58), frequency of eye ointment injection after operation(OR=0.001), history of lacrimal duct catheterization(OR=0.0009), history of lacrimal laser(OR=94.73),packing material(OR=0.002)were the independent factor influencing the efficacy.

CONCLUSION: Rhinitis and history of lacrimal laser are the factors to reduce the curative effect of endoscopic dacryocystorhinostomy; regular injection of eye ointment after operation, history of lacrimal duct catheterization and filling of absorbable materials, which are beneficial to improve the curative effect of operation.
