TitleBacterial Profile and Antibiotic Susceptibility Pattern of Bacterial Keratitis at Tertiary Hospital in Riyadh
PurposeTo identify the most common predisposing factors and causative organisms of bacterial keratitis as well as its antibiotic profile in tertiary care hospital in Riyadh, Saudi Arabia.
MethodsA retrospective study of all cases had a positive culture of bacterial keratitis from corneal scraping. Age, gender, diabetes mellitus, contact lens use, history of eye trauma, ocular diseases, recent ocular surgeries, current and recent medications, initial and final visual acuity (VA) (final VA was based on the last follow up), location and size of the infiltrate, presence of hypopyon and complications were identified.
ResultsThe most common cause of bacterial keratitis was Staphylococcus epidermidis (N=61) followed by Streptococcus pneumoniae (N=23). Trauma was the most common predisposing factor (38.4%) while the contact lens was identified only in 14 cases (7.9%). All organisms tested were sensitive to vancomycin and there was high resistance toward penicillin (90%).
ConclusionThe results of our study will be helpful in clinical practice and accurate select of antimicrobial therapy.
