[Treatment refractory multidrug-resistant bacterial keratitis].

This article reports a case of severe, treatment refractory infectious keratitis. Multiple samples of the cornea and the anterior chamber were taken without detection of any pathogens. Ultimately a multidrug-resistant Pseudomonas aeruginosa was isolated and successfully treated with tobramycin and amikacin, according to its antibiotic sensitivity. If there is a clinical suspicion multiple samples should be taken and multidrug-resistant pathogens considered as a differential diagnosis.
