Comparative Efficacy of Topical Moxifloxacin Versus Ciprofloxacin and Vancomycin in the Treatment of P. aeruginosa and Ciprofloxacin-Resistant MRSA Keratitis in Rabbits

Topical moxifloxacin 0.5% and ciprofloxacin 0.3% have similar efficacy in the treatment of Pseudomonas aeruginosa keratitis in rabbits. Topical moxifloxacin 0.5% and vancomycin 50 mg/mL have similar efficacy in the treatment of ciprofloxacin-resistant MRSA keratitis in rabbits. These results suggest a potential value for topical moxifloxacin as a broad-spectrum agent in the treatment of bacterial keratitis.
