Abstract Purpose:Corneal crosslinking(CXL)is a treatment to prevent the progression of keratoconus, and infection is a rare but serious complication of CXL. Herein, we report a case of severe infectious keratitis after CXL in a patient with atopic dermatitis.

Case:The patient was a 24-year-old male with a history of atopic dermatitis. He underwent CXL for keratoconus using the standard method of corneal epithelial detachment at his previous clinic. Three days after the procedure, he developed ocular pain in his right eye, following which he was referred to our hospital because of suspicion of infectious keratitis. At the time of the initial examination, edema of the entire right cornea, central corneal infiltration, and epithelial defects were observed, and the visual acuity of the right eye was 30 cm hand motion. Smear examination and culture tests failed to identify the causative organism. Treatment was started with topical antimicrobial eye drops(vancomycin hydrochloride, hourly;1.5% levofloxacin hydrate, hourly)and systemic antibiotic administration(minocycline hydrochloride 200 mg/day, cefazolin sodium 3 g/day). Nine months later, a full corneal transplant was performed, and the patient had good postoperative corrected visual acuity(1.2).

Conclusion:We experienced a case of suspected a severe corneal infection with an unknown pathogen after CXL. The detection rate of Staphylococcus aureus is high in patients with atopic dermatitis, as in this case, and the problem of resistant bacteria has been reported. Therefore, we believe that caution is necessary when performing CXL with corneal epithelial removal.
