Clinical characteristics and outcomes of patients admitted with presumed microbial keratitis to a tertiary medical center in Israel.

PURPOSES

Microbial keratitis is commonly diagnosed worldwide, and continues to cause significant ocular morbidity, requiring prompt and appropriate treatment. The objective of this study is to describe the clinical characteristics and outcomes of patients with presumed microbial keratitis admitted to The Goldschleger Eye Institute, Sheba Medical Center, Tel Aviv University, Tel Hashomer, Israel.

METHODS

A cross-sectional study was conducted, in which the medical records of patients with presumed microbial keratitis admitted during a period of 3 years were reviewed.

RESULTS

Keratitis was diagnosed in 276 patients (51% males and 48.9% females). The mean age was 39.29 ± 22.30 years. The hospital length of stay ranged from 1 to 65 days (mean 5.69 ± 5.508). Fortified antibiotics were still used at discharge in 72% of the cases. Overall visual acuity improved significantly from the time of admission to the 1st-week follow up visit showing a p<0.001 on the Wilcoxon signed ranks test. Contact lens wearing was present in 36.1% of the patients, although there was no significant relation with severity of the presentation and visual outcome (p>0.05). The degree of hypopyon and cells in the anterior chamber was significantly related to the hospital length of stay (r Spearman=0.31; p<0.001 and r Spearman=0.21; p<.001, respectively) as well as to a worse visual outcome (r Spearman=0.32; p<0.01 and r Spearman=0.18; p=0.01, respectively). Of all patients, 2.3% required an urgent therapeutic penetrating keratoplasty, and 1% underwent evisceration. There was no enucleation.

CONCLUSION

Treating keratitis aggressively and assuring patient compliance is imperative for a good final visual outcome. Inpatient treatment may have a positive impact on this outcome.
