Abstract

PURPOSE-To study the bacteriological etiology of dacryocystitis and antibiotic susceptibility of pathogens. METHODS- An observational study done between November 2019 and April 2021.Specimens obtained by cotton swabs from the lower conjunctival fornix, from the puncta by pressing over the lacrimal sac or by performing lacrimal syringing. Specimens were inoculated on culture media. Bacterial identification was followed by Antibiotic Susceptibility Testing. RESULTS-Out of total 50 patients, 74% had chronic and 26% had acute dacryocystitis. Gram positive bacteria were the most isolated bacteria(77.2%). In chronic dacryocystitis, the predominant bacteria were Staph.epidermidis (36%), while in acute dacryocystitis it was Staph.aureus (40%). Against gram-positive bacteria, Vancomycin and Linezolid were most sensitive(100%) and against gram-negative, Amikacin was most sensitive(100%).CONCLUSION- A knowledge of the etiology of dacryocystitis contributes to the choice of antimicrobial agent.
