Recently, it has been identified as a cause of fungal keratitis, particularly among contact lens wearers.

Initial examination revealed a central corneal infiltrate. IVCM was performed prior to corneal scraping, which was then sent for direct staining, culture, and next-generation sequencing (NGS) and identified Pyrenochaeta unguis-hominis and Streptococcus oralis. Treatment included hourly topical voriconazole 2 %, natamycin 5 % and vancomycin 2.5 %, with additional epithelial debridement to enhance drug penetration. IVCM imaging allowed for real-time visualization and tracking of structures with the appearance of fungal hyphae, guiding the treatment course.
