Abstract

Abstract: : Purpose: To determine the antibiotic susceptibility patternof coagulase-negative staphylococci (CNS) in patients undergoinganterior segment intraocular surgery.Methods: Conjunctivalcultures were obtained (prior to application of antibiotic orantiseptic agent) from 66 consecutive patients undergoing intraocularsurgery who consented to this prospective study. All bacteriaisolates were identified and antibiotic susceptibility determinedby Kirby-Bauer disc-diffusion technique.Results: A total of76 CNS were isolated.

This study suggeststhat fluoroquinolones and aminoglycosides are effective prophylacticantibiotics against most coagulase-negative staphylococci. Support:Edward E.
