Aims:to assess microorganisms causing CNLDO. To see efficacy of probing as compared to silastic intubation. Material and methods:100 patients were enrolled in the study. Patients came with epiphora and mucous discharge. Inclusion criteria for the study was patients presenting with CNLDO (Presence of atleast one sign of NLDO:Epiphora, increased tear lake, and/or mucopurlent discharge), Age upto 9 years. Exclusion criteria:Punctual or canalicular abnormality, H/o previous surgery, H/o faciomaxillary trauma, cleft lip/ cleft palate or any facial deformity, acute dacryocystitis, previous history of probing. Sample size was 100 patients. Results: Haemophilus influenzae and Streptococcus pneumonia were the most common microorganisms (n= 56, 40.5%; n= 37, 26.8% respectively) followed by Moraxella catarrhalis (n=19, 13.7%), Staphylococcus aureus (n=17, 12.3%), Pseudomonas aeruginosa (n=9, 0.65%). In conclusion the mocobiological study of CNLDO may have a value in predicting the obstruction.
