PURPOSE: The aim of this paper is to present the case report of a patient developing endophthalmitis after penetrating keratoplasty caused by a multidrug-resistant Pseudomonas aeruginosa, detected only in the contralateral donor tissue. CASE REPORT: A 77-year-old man underwent an uneventful penetrating keratoplasty with a preoperative culture-negative donor cornea; however, the fellow cornea grew multidrug-resistant Pseudomonas aeruginosa. The patient developed and was treated for endophthalmitis after penetrating keratoplasty, and aqueous and vitreous taps grew P. aeruginosa with antibiotic resistance identical to the isolate from the mate cornea. Sequence analysis of the 16S ribosomal gene from the two isolates and confirmation analyzing the sequence of P. aeruginosa heat shock protein gene (groES) were performed showing the same strain for both organisms. CONCLUSION: This case report documents the presence of the same multidrug-resistant P. aeruginosa causing endophthalmitis after penetrating keratoplasty and in the contralateral donor tissue, suggesting that we must be cautious in deciding to transplant tissues with positive culture in the contralateral donor cornea.
