In vitro Activity of Fluoroquinolones, Vancomycin, and Gentamicin Against Methicillin-Resistant Staphylococcus aureus Ocular Isolates

MRSA ocular isolates exhibited a relatively high rate of in vitro resistance to all fluoroquinolones tested, including the fourth generation. In contrast, MRSA isolates were found to be highly sensitive to vancomycin and gentamicin.
