Daytime Orthokeratology Associated With Infectious Keratitis by Multiple Gram-Negative Bacilli: Burkholderia cepacia, Pseudomonas putida, and Pseudomonas aeruginosa

Abstract

PURPOSE: To report a case of a corneal ulcer in a patient who wore orthokeratology contact lenses during the day. METHODS: Case report. RESULTS: A 16-year-old girl who underwent orthokeratology treatment developed a corneal ulcer in her right eye. The refractive status of the affected eye was -5.75 -1.75 x 180, and the best-corrected visual acuity was 20/40. Corneal topography showed the temporal upper dislocation of a central flattened zone in the right eye. The patient had worn orthokeratology contact lenses during the day for more than 4 years. Her ulcer became worse after treatment with tobramycin and gentamicin for 1 day. After treatment with ciprofloxacin, the ulcer healed, and visual acuity returned to 20/20 with spectacle correction. Cultures of the cornea, contact lens, and lens solution all grew Burkholderia cepacia, Pseudomonas putida, and Pseudomonas aeruginosa. CONCLUSIONS: Improper fitting of lenses and contamination of lenses or solutions in orthokeratology therapy are risk factors for a corneal ulcer, even when patients wear orthokeratology lenses only during the day.
