Purpose: To report a case of corneal ulcer caused by Stenotrophomonas maltophilia monomicrobial infection in an otherwise healthy patient, devoid of underlying medical conditions or predisposing factors.Case summary: A 48-year-old male patient, who was normally healthy without a history of systemic disease, eye trauma, and eye surgery, presented with acute left eye pain that had manifested one day prior. Ophthalmic examination revealed conjunctival injection, corneal edema, and localized corneal ulceration in the left eye. Suspecting infectious keratitis, diagnostic procedures including gram staining, bacterial and fungal cultures, and antibiotic susceptibility testing were promptly instituted. Bacterial culture identified S. maltophilia, prompting an eight-week course of topical gatifloxacin therapy. The subsequent clinical course exhibited improvement, with lingering corneal haziness and the restoration of visual acuity to 1.0.Conclusion: The case featuring the single detection of S. maltophilia, known to cause hospital-acquired opportunistic infections, emphasizes the importance of culture and antibiotic susceptibility testing in the treatment of keratitis. Remarkably, in a patient with a normal immune status and in the absence of factors predisposing to S. maltophilia infections, there were no discernible causative factors damaging the ocular surface environment.

Purpose: To report a case of contact lens-related infectious keratitis caused by three different bacterial species.Case summary: A 40-year-old man presented with pain and redness in his left eye. His best-corrected visual acuity (BCVA) in the affected eye was 20/25. Slit-lamp examination revealed a 3 × 3 mm corneal epithelial defect with infiltration located 1 mm inferior to the pupil. Following admission, a microbial culture test was performed, and empirical antibiotic therapy was initiated. On the fourth day, Pseudomonas aeruginosa was isolated from the corneal sample and the contact lens, while Serratia marcescens and Stenotrophomonas maltophilia were isolated from the contact lens case. Based on the results of the antibiotic susceptibility tests, 0.5% moxifloxacin, fortified amikacin, and ceftazidime were administered topically and intravenously. The corneal epithelial defect reduced to 1 × 1 mm by the eleventh day of admission. After two months, BCVA improved to 20/20 with no remaining corneal epithelial defect, although an inactive corneal opacity persisted at the previous ulcer site.Conclusions: Contact lens wear can be associated with polymicrobial keratitis involving three distinct Gram-negative bacteria, which may present greater treatment challenges compared to monomicrobial keratitis. Microbial culture testing of the contact lens, its case, and corneal scrapings is essential for identifying the causative organisms and selecting appropriate antibiotic therapy.
