Visual Outcome and Bacterial Sensitivity After Methicillin-Resistant Staphylococcus aureus-Associated Acute Endophthalmitis

MRSA infection accounts for 18% of culture-positive cases of endophthalmitis in this study and was associated with a poor visual outcome in two-thirds of our patients. MRSA organisms may be resistant in vitro to all generations of fluoroquinolone antibiotics, but do seem to be sensitive to gentamicin and vancomycin. The incidence of MRSA endophthalmitis seems to have increased significantly since the Endophthalmitis Vitrectomy Study was published in 1996.
