Purpose: The aim of this study is to report the clinical characteristics, visual outcomes, and antibiotic susceptibilities of patients with Pseudomonas aeruginosa endophthalmitis.
Methods: The medical records of patients with culture-proven Pseudomonas aeruginosa endophthalmitis treated from June 2013 to December 2019 were reviewed.
Results: This study included 36 eyes of 36 patients. The clinical settings included ocular trauma (15/36), corneal ulcer (9/36), postoperative endophthalmitis (5/36), endogenous (3/36), and unknown (4/36). Sixteen patients underwent evisceration, 13 patients underwent pars plana vitrectomy (PPV), 2 patients were treated with only intravitreal antibiotics, and 5 patients did not undergo surgery. Only one patient achieved a visual acuity of 20/400, and the others had all counting fingers or below. The cultured Pseudomonas aeruginosa was 100% sensitive to gentamicin, tobramycin, amikacin, ciprofloxacin, and levofloxacin and, approximately 95% sensitive to meropenem, imipenem, and aztreonam.
Conclusion: The visual outcomes of Pseudomonas aeruginosa endophthalmitis were very poor, and the evisceration rate remained high. Pseudomonas aeruginosa has good susceptibility to gentamicin, tobramycin, amikacin, ciprofloxacin, and levofloxacin.
