We report a case of acute postoperative endophthalmitis caused by vancomycin-resistant Staphylococcus hominis, treated at our hospital. An 80-year-old male presented 2 days after uncomplicated phacoemulsification and posterior chamber intraocular lens implantation, with a 24-hour history of progressive visual loss and redness in the operated (right) eye. On examination, best corrected visual acuity was counting fingers. Anterior segment examination revealed conjunctival injection, chemosis, corneal edema, and hypopyon. B-scan ultrasonography showed vitreous opacification, but no retinal detachment. Acute postoperative endophthalmitis was diagnosed. We performed vitrectomy with vancomycin in the irrigating solution, intraocular lens removal, and silicone oil tamponade. Culture of the vitreous grew Staphylococcus hominis. Antibiotic susceptibility testing showed the isolate was sensitive to trimethoprim/sulfamethoxazole and teicoplanin but resistant to ciprofloxacin, moxifloxacin, levofloxacin, cefazolin, and vancomycin. At 3 months, the visual acuity of the silicone oil-treated eye was 20/400.
