BACKGROUND: Pressurized probing and irrigation is the method of choice for @entity11939 after conservative therapeutic strategies have failed. The aim of this study was to evaluate age @entity734 and success rates of different therapeutic options. MATERIAL AND METHODS: A prospective cohort study of @entity1 with @entity11939 was performed. All @entity1 treated during the period between May 2009 and June 2010 were included. Surgical success was defined as the absence of @entity9467 and mucous discharge for a postoperative follow-up of 3 months. Odds ratios (OR) and 95   % confidence intervals (CI) of different variables were estimated using logistic regression. RESULTS: A total of 111 @entity1 (137 eyes) underwent treatment for @entity11939 . The mean age of the @entity1 was 7.7 months (range 1-30 months). The success rate of probing under local anesthesia was 85.5   % (n   =   100). Probing under general anesthesia without intubation of the lacrimal pathway was successful in 28.6   % (n   =   2). Treatment under general anesthesia with intubation of the lacrimal pathway had a success rate of 94.2   %. If the primary treatment was complicated the OR was 1.9 (95   % CI: 0.7-5.1), for males the OR was 1.7 (95   % CI: 0.8-3.5) and in cases of a positive family history the OR was 1.5 (95   % CI: 0.7-3.3). With every increasing month of age the risk not to be treated successfully increased (OR: 1.3, 95   % CI: 1.2-1.5). CONCLUSION: Syringing under local anesthesia is an effective therapy. The highest success rates were found at the ages of 1-6 months. Therapy with additional @entity1346 tube intubation was highly successful.
