Pediatric Metarrhizium anisopliae keratitis.

Metarrhizium anisopliae (M. anisopliae) is an entomopathogenic fungus used as an agricultural pesticide in many countries, including the United States. M. anisopliae grows optimally at 25°C and is therefore considered safe to humans. We report a case of a 12-year-old girl who is a soft contact lens wearer with M. anisopliae corneal ulcer who was treated effectively with topical natamycin after identification of the organism by corneal culture. Topical amphotericin B was not effective.
