Delayed-onset Pseudomonas stutzeri endophthalmitis after uncomplicated cataract surgery

An 88-year-old woman had uneventful extracapsular cataract extraction with posterior chamber intraocular lens (IOL) implantation in her right eye. Seven weeks later, an anterior vitrectomy with removal of the IOL was performed because of endophthalmitis resistant to topical and systemic amoxicillin, cephalosporin, aminoglycoside, and steroids. Microbiological examination of the vitreous biopsy, capsule, and anterior chamber fluid disclosed Pseudomonas stutzeri, gram-negative nonfermentative bacteria sensitive to tetracycline, ceftazidime, gentamicin, ofloxacin, and piperacillin. Pseudomonas stutzeri should be considered in the treatment of delayed-onset endophthalmitis.
