Ochrobactrum anthropi Keratitis with Focal Descemet's Membrane Detachment and Intracorneal Hypopyon.

Purpose. To describe a unique case of O. anthropi keratitis associated with a rare manifestation of Descemet's membrane detachment and intracorneal hypopyon and to discuss challenges in diagnosis and management. Methods. Best-corrected visual acuity was measured with Snellen letters. Corneal scrapings were performed and aerobic, viral, herpetic, acid-fast bacilli, Acanthamoeba, and fungal stains and cultures were obtained. Following evisceration, tissue was evaluated for histologic features and again stained for bacteria, mycobacteria, Acanthamoeba, fungi, and viral particles. Results. Initial presentation to our institute was notable for a corneal ulcer, focal Descemet's membrane detachment, and intracorneal hypopyon. Speciation of initial corneal scrapes revealed Ochrobactrum anthropi and initial management included fortified tobramycin. Despite medical therapy, the patient developed a corneal perforation and required subsequent evisceration. Conclusion. O. anthropi is an emerging ocular pathogen that has not been previously reported in cases of keratitis. As this pathogen becomes increasingly recognized as a source of ocular infections, it is important to identify and treat aggressively to avoid vision-threatening disease.
