Resumen
ALANON, F.J. et al. Ballon dacryocystoplasty (DCP) for treatment of pediatric patients with congenital nasolacrimal duct obstruction after failed primary probing. Arch Soc Esp Oftalmol [online]. 2007, vol.82, n.10, pp.609-614. ISSN 0365-6691.
Purpose: To determine the efficiency of lacrimal balloon catheter dilatation to treat congenital nasolacrimal duct obstruction in children who had failed two lacrimal system probings. Methods: Between October 2004 and June 2006 we performed a prospective study of balloon catheter dilatation for congenital nasolacrimal duct obstruction in 30 lacrimal systems. The mean age was 32.4 months (range 18-72 months). The patients were divided into 3 types of obstructions: partial, proximal and simple membranous at the valve of Hasner and into 2 age categories: category 1 (18-36 months) and category 2 (> 36 months). The patients were evaluated 2 weeks, 3 months and 6 months after balloon catheter dilatation, with Munk's score and ophthalmic evaluation using a dye disappearance test being assessed. Clinical patency was defined as a complete resolution of signs and symp-toms (Munk 0) and a negative disappearance test (grade 0). We used the chi-squared test with Yates´ correction for statistical analysis. Results: The procedure was successful in 83.33% of the cases and there were no complications. Statistical analysis showed no significant difference between the 3 types of obstructions treated, and age at treatment did not affect the outcome. Conclusion: DCP is a safe, effective therapy, easy and fast to perform and should be used in the treatment of congenital nasolacrimal duct obstruction after failure of two lacrimal system probings.
