Abstract
BACKGROUND: This case report describes the course and therapeutic management of a fast-spreading bacterial keratitis caused by multidrug-resistant (MDR) Pseudomonas aeruginosa (P. aeruginosa). CASE PRESENTATION: A 27-year-old male contact lens wearer presented with a multi-resistant, fast spreading P. aeruginosa keratitis. After initial resistance to various antibiotic therapies, testing revealed a MDR P. aeruginosa. The keratitis was treated successfully with specially prepared 50 mg/ml off-label meropenem eye drops for 18 days as well as systemic meropenem for seven days with rapid improvement of the corneal infiltrate. CONCLUSION: This case report demonstrates the combination of topical and systemic meropenem as a useful treatment option for corneal ulcers caused by MDR P. aeruginosa.
