Bacterial keratitis: predisposing factors, clinical and microbiological review of 300 cases

To identify predisposing factors and to define clinical and microbiological characteristics of bacterial keratitis in current practice.

A retrospective analysis of the hospital records of patients presenting with bacterial keratitis and treated at the Quinze-Vingts National Center of Ophthalmology, Paris, France, was performed during a 20 month period. A bacterial keratitis was defined as a suppurative corneal infiltrate and overlying epithelial defect associated with presence of bacteria on corneal scraping and/or that was cured with antibiotic therapy.
