Answer

Most community-acquired cases of bacterial keratitis resolve with empiric therapy and are managed without cultures. However, cultures are indicated in cases that involve a corneal infiltrate that is central and large and extends to the middle to deep stroma, cases that are unresponsive to antibiotic therapy, and cases that have atypical clinical features suggestive of fungal, amoebic, or mycobacterial keratitis.
