Abstract

Purpose: To present the success rate in treating congenital nasolacrimal duct obstruction with hydrostatic pressure (Crigler method). Methods: Clinical data from 186 children aged up to 32 months treated from 1990 until 2005 were reviewed retrospectively. The procedure was repeated up to 3 times at a one week interval. Using EPI INFO version 6.04 software for analysis, data were tabulated and statistical significance was evaluated by applying chi-square and Kruskal-Wallis tests. Results: Leading age group was 1 to 5 months old (56.4%) for males and females. Affection was bilateral in 36.3%, 34.1% on right side and 29.6% on the left side. All cases had epiphora and 56.5% presented mucopurulent discharge. Cure was achieved with one massage for 43.6%, 23.3% with two, 17.4% with three and, with 4 and 5+ sessions in respectively 5.8% and 9.0%. Those 14 cases who did not respond to massage were treated with probing. Conclusion: The Crigler method was effective in managing congenital nasolacrimal duct obstruction cases.
