Purpose: To report a case of Xanthomonas maltophilia endophthalmitis and to increase awareness of its potential as an intraocular pathogen.
Method: Case report.
Results: A 76-year-old woman developed X maltophilia endophthalmitis after cataract extraction. To eradicate the infection, we performed two vitrectomies and treated the patient with numerous intravitreal antibiotic injections.
Conclusions: X maltophilia is a potential intraocular pathogen in an immunocompetent host. If the infection takes a persistent course, persistent topical and intravitreal antibiotic treatment and possibly vitrectomy are needed to eradicate the infection.
