Purpose: To report a case of subacute methicillin-resistant coagulase-negative Staphylococcus hominis endophthalmitis after re-operation for penetrating keratoplasty in a patient who had a penetrating keratoplasty rejection.
Case summary: A 74-year-old man with underlying diabetes and hypertension who underwent bilateral penetrating keratoplasty at another hospital underwent penetrating keratoplasty reoperation due to corneal transplant rejection in the right eye. He had a history of end-stage glaucoma in the right eye and the visual acuity was finger counting at 30 cm. About 25 days postoperatively, the corneal epithelial defect was first found. Treatment based on suspicion of herpes simplex virus infection did not result in improvement and endophthalmitis was suspected in the right eye about 35 days after surgery. Anterior chamber irrigation, pars planar vitrectomy, and intravitreal antibiotic injection were performed. Culture revealed methicillin-resistant coagulase negative Staphylococcus hominis. After 2 months of treatment, the anterior chamber and vitreous inflammation decreased and best corrected visual acuity in the right eye recovered to 0.06.
Conclusions: Subacute endophthalmitis caused by methicillin-resistant coagulase-negative Staphylococcus may occur after penetrating keratoplasty. Transplant failure due to infection can be avoided with vitrectomy and antibiotic treatment at the right time.
