Keratitis Due to Achromobacter xylosoxidans in a Contact Lens User.

OBJECTIVES: Ocular infections due to Achromobacter xylosoxidans are extremely uncommon; their diagnosis is a challenge and the optimal treatment remains controversial. We present a case of A. xylosoxidans in a contact lens user and a review of the literature to facilitate diagnostic suspicion and empirical therapeutic management.

METHODS: Review of the literature in PubMed and MEDLINE. We also document a case diagnosed in our department in January 2016.

SETTING: Hospital Clínico Universitario Lozano Blesa, Zaragoza, Spain.

RESULTS: According to the literature, clinical manifestations and antibiotic sensitivity of A. xylosoxidans varied greatly. Our patient with no history of keratopathy presented three risk factors that made the diagnosis suspicious. The infection was resolved with topical moxifloxacin and fluorometholone.

CONCLUSIONS: A. xylosoxidans is an uncommon cause of infection, but must be suspected in atypical keratitis, reported contact with warm or still waters, use of contact lenses, or previous corneal damage. In these cases, microbiological studies and antibiotic sensitivity testing are particularly important.
