A Rare Polymicrobial Keratitis Involving Chryseobacterium meningosepticum and Delftia acidovorans in a Cosmetic Contact Lens Wearer

OBJECTIVE: To report an unusual case of keratitis in a cosmetic contact lens wearer caused by two rare organisms. METHOD: Case report. RESULTS: A 14-year-old cosmetic contact lens user presented with a paracentral corneal ulcer in her right eye. The cosmetic lenses were bought online. The cultures from corneal scrapings and contact lenses demonstrated heavy growth of Chryseobacterium meningosepticum and Delftia acidovorans. The treatment with topical ciprofloxacin and fortified gentamicin was effective, and the infection resolved with corneal scar after 5 weeks. CONCLUSION: Use of cosmetic contact lenses and buying them online is a fairly common practice among teenagers. This can lead to serious eye infection as in this case. To our knowledge, this is the first report of contact lens-related keratitis simultaneously involving these two rare organisms.
