Slit lamp examination showed teardrop-like stromal infiltration of the superior cornea. Corneal and conjunctival scrapings were obtained and a corneal biopsy was performed. Results. Microscopic examination of smears demonstrated no bacteria and fungi. Corneal biopsy revealed dichotomously branching, septate hyphae suggestive of Aspergillus species.
