Abstract
Aim- To determine the success rate of probing for congenital nasolacrimal duct obstruction in children under 2 years of age and to compare success rate of early and late probing in such children.
Material and Methods- The study was done in 55 children undergoing probing for congenital nasolacrimal duct obstruction. The children were divided in two groups. Group – I (6-12 months) and group- II (13-23 mnths). The procedure was performed with Bowman’s probe under general anesthesia. Patients were seen in OPD at 1st day,1st week, one month and 3rd month after probing. Success of probing was the main outcome measure and was defined as complete remission of watering, discharge and reflux of contents of the lacrimal sac on pressure at one week of the procedure.
Results- The success rate in group I was 96.66% and 80% in group II. The overall success rate by single probing was 89.9%.The decrease in success rate after 13 months was statistically significant(p<0.001)
Conclusions- Delay in initial probing beyond 13 months of age results in decreasing success as well as increasing complications of therapy.
Key Words –nasolacrimal duct obstruction, probing, general anesthesia, bowman’s probe.
