Isolated Microbes in Patients Admitted with Corneal Ulcer

Background and Objectives: Severe corneal ulcer is an ocular emergency. The aim of this study was to identify the predisposing factors, microbial isolates and therapeutic results of patients with corneal ulcer.Materials and Methods: In a prospective study, between" 2003-2004" all patients with corneal ulcer, who admitted to Nikookari hospital, were evaluated by corneal scraping. All samples were studied by gram staining and micro biological culture.Results: Corneal scraping was performed in 100 patients (M/F = 65/35, 51-80 years). Thirty one percent were farmer. Previous corneal surgery had been performed in 30% of patients. The most common organism in gram stain was staphylococcus Epidermidis (58%) and topical Cephazolin and Gentamycin were used in 89% of cases. Corneal ulcer was healed in 74% of patients with medical therapy.Conclusion: In this study, staphylococcus epidermidis was the most common organism and previous eye surgery was the most predisposing factor for development of corneal ulcer.
