Abstract
- Infectious keratitis is the most common serious ocular infection, and may be caused by various bacteria, fungi, viruses and parasites. The authors performed prospectively an epidemiological study to identify risk factors and causative organisms, and to evaluate clinical manifestations, methods and results of treatment in infectious keratitis under the identical protocol from April 1995 to September 1997. Logistic regression analysis [univariate analysis and multivariate analysis] was used to evaluate possible risk factors. Six hundred sixty cases of infectious keratitis reported from 19 hospitals were studied. Two hundred eighty-three organisms[247 bacteria, 32 fungi, 4 acanthamoeba] were detected in 626 eyes with infectious keratitis excluding 34 pherpetic keratitis. The Pseudomonas aeruginosa, coagulase negative staphylococcus, Staphylococcus aureus and Serratia marcescens were the major orgnisms in bacterial keratitis. Aspergillus, Fusarium and Candida were the major isolates in fungal keratitis. Contact lens wear was a risk factor for bacterial keratitis. Female, age[less than 40 years] and occupation[student, house-wife, office worker, servise] were associated with bacterial keratitis. Risk factors in herpetic keratitis were age[between 40 and 59 years] and ocular adnexal diseases. Male was associated factor with herpetic keratitis.
