Abstract :
To assess the practical difficulties and results of probing for Congenital Naso Lacrimal Duct Obstruction
under topical anesthesia. 500 infants (650 eyes) were selected. Age ranges from 3-12 months and study was
done over a period of 10 years. Probing was done in those children in which medical treatment (antibiotic
drops and sac massage) have failed. Topical anesthesia (Lidocaine 4%/ Proparacaine 0.5%) was used for
probing. This procedure was successful in 95.2% in first & 98.4% in second sitting without any significant
complication. Thus probing under topical anesthesia is a shorter & convenient method.
