Fungal keratitis caused by Laetisaria arvalis.

A 53-year-old female presented with keratitis (right eye) after fall of insect 10 days back. The ulcer worsened in spite of aggressive treatment with topical natamycin (5%) and amphotericin-B (0.15%) eye drops and finally perforated. Iris tissue sealed the perforation site, and ulcer healed with formation of adherent leucoma. This case represents first reported case of keratitis caused by Laetisaria arvalis and stresses on aggressive course of keratitis caused by this fungus. Importance of DNA sequencing in identification of unidentified fungal species is also highlighted.
