AIM: To compare the therapeutic effect of the improved flushing probing of lacrimal passage and probing flush integrated for treatment of congenital nasolacrimal duct obstruction.

METHODS: Totally 252 cases(273 eyes)of congenital nasolacrimal duct obstruction, admitted in our outpatient department from July 2008 to September 2012 were observed; One hundred and forty cases(156 eyes)were treated with improved flushing probing of lacrimal passage treatment, and 112 cases(117 eyes)were treated with probing flush integrated treatment; The therapeutic effects of the two methods were compared and followed-up time was 1 week to 1 month.

RESULTS:The improved flushing probing of lacrimal passage group had 152 eyes successful probing at once, 2 eyes failed during follow-up. The probing flush integrated group had 107 eyes successful probing at once, 8 eyes failed during follow-up. Difference between the two groups was statistically significant(P<0.05).

CONCLUSION:Compared the effect of treatments of congenital nasolacrimal duct obstruction,the improved flushing probing of lacrimal passage is significantly better than probing flush integrated.
