To report several cases of secondary infection by fungus in herpes simplex keratitis.
Case summaryA retrospective chart review was performed on 3 eyes of 3 patients who were without improvement and diagnosed with fungal keratitis by smear and culture on prior presentation with herpetic keratitis. Two cases were diagnosed with fungal keratitis, based on the results of culture. Fungal keratitis by Candida albicans was improved with antifungal agents, but a case caused by Fusarium species was more aggravated, regardless of antifungal agents. One case was improved by antifungal medications, which was diagnosed with fungal keratitis by the fungal hyphae manifestation on KOH preparation.
ConclusionsSecondary microbial infection should be considered, when the lesion had no improvement with antiviral agents in herpetic keratitis.
