Enterobacter cloacae Keratitis in a Patient with Severe Dry Eye: A Rare Case

Corneal ulcers are vision-threatening emergencies.Bacterial pathogens such as Staphylococcus, Streptococcus, and Pseudomonas are most frequently implicated in microbial keratitis. 1The integrity of the corneal epithelium is critical in preventing infections, as it acts as a physical and immunological barrier.Enterobacter cloacae is a Gram-negative rod in the Enterobacteriaceae family, commonly present in the environment and human gut microbiota.Although increasingly linked to nosocomial infections, 2 ocular involvement remains rare.The prevalence of E. cloacae keratitis ranges from 0.13% to 15.3%. 1,3Most documented cases involve penetrating keratoplasty (PK), graft failure, chronic corneal edema, or topical corticosteroid use. 3,4,5,6
