Abstract
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.
