Purpose: To determine the success rate of probing for congenital nasolacrimal duct obstruction in children older than 13 months of age.
Methods: In a retrospective study of 84 children, 13 months and older who underwent probing for congenital nasolacrimal duct obstruction, the age at probing was correlated with success of probing. The children were divided into two groups, Group 1(13 - 24 months) and Group 2 (>24 months). Success was defined as complete resolution of signs and symptoms. The chi-square test was used to analyse the result.
Results: The success rate was 88.1% in-group 1 and 80.1% in-group 2 (P = 0.84). There was no significant difference in the cure rate with increasing age (P = 0.6).
Conclusion: Probing is highly successful in the older age group and should remain the first line of treatment in older children.
