Photographs of the right eye before and after treatment. a At the first visit, a whitish infiltration with a feathery edge, satellite (red arrow), and a brownish pigmented lesion (green arrow) on the epithelial surface and anterior stroma were presented at cornea. b One week after medical treatment, dense infiltrates and corneal plaques were found. c Five weeks after medical treatment, the lesion was replaced by a corneal scar without an overlying superficial corneal plaque and epithelial defect. d The lesion became a corneal scar after 2 months of treatment.

A whitish infiltration with a feathery edge, satellite, and a brownish pigmented lesion on epithelial surface and in the anterior stroma of the temporal site of the right cornea were found in his right eye with slit-lamp examination (Fig. 1a). The edge of the infiltrate remained dense, and the overlying epithelial defect and corneal plaque increased in size (Fig. 1b). After 5 weeks of treatment, the lesion was improved and replaced by a corneal scar without an overlying superficial corneal plaque or epithelial defect (Fig. 1c). Four weeks after discharge, the lesion improved, with no recurrence infiltration and no anterior chamber inflammation; however, the lesion was replaced with a corneal scar (Fig. 1d).
KOH examination (a) and calcofluor-white staining (b) showed numerous large septate hyphae. c, d Fungal culture revealed numerous dematiaceous fungi of Exserohilum rostratum (asexual state).

The KOH examination and calcofluor-white staining showed numerous large septate hyphae (Fig. 2a, b). The consequence of the previous fungal culture revealed numerous unidentified dematiaceous fungi (Fig. 2c, d).
