Abstract

Purpose. To identify the major pathogens in adult dacrocystitis and pediatric nasolacrimal duct obstruction. Methods: Microbiology records at The New York Eye and Ear Infirmary from June to November, 1995 (6 months) were reviewed. All cultures from the lacrimal sac were accumulated for analysis. Results: Patients fell into two age groups: 1.) Adult, mean age 61.6 yr (range: 19-88 yr) and 2.) Pediatric, mean age 1.05 yr (range: 2.5 wk-6 yr). Thirty-six isolates were obtained from 25 adult patients, and 21 isolates were obtained from 18 pediatric patients. Major lacrimal sac isolates from adult patients were coagulase negative Staphylcoccus (28%) and Staphylococcus aureus (25%) as compared to Haemophilus influenzae (19%), coagulase negative Staphylococcus (14%), and Pseudomonas aeruginosa (10%) in pediatric patients. Conclusions: Staphylcoccus species were the most commonly isolated pathogens from the lacrimal sac of adults with dacrocystitis and children with nasolacrimal duct obstruction, but H. influenzae and P. aeruginosa were important pathogens in pediatric nasolacrimal duct obstruction. These results demonstrate a bimodal age distribution for infectious agent-related pathology of the nasolacrimal drainage system and a difference in the predominant organisms isolated from the two age groups. Knowledge of the most common isolates allow appropriate selection of topical and/or systemic antibiotics in the primary treatment of these entities.
