Post-traumatic Fungal Keratitis and Endophthalmitis Caused by Coniochaeta Hoffmannii with Late Recurrence following Therapeutic Full-thickness Penetrating Keratoplasty.

BACKGROUND: To report a rare case of fungal keratitis and endophthalmitis due to Coniochaeta hoffmannii. METHODS: Case report. RESULTS: A 71-year-old immunocompetent male sustained a corneal laceration, traumatic cataract, and retinal detachment due to penetrating injury from a nail pulled from a wooden deck. The patient's postoperative course was complicated by infectious keratitis. Fungal cultures, DNA sequencing and analysis of the internal transcribed spacer sequence confirmed Coniochaeta hoffmannii. Topical and oral voriconazole treatments were initiated; however, due to impending perforation, a therapeutic corneal transplant was required. One year later, the patient developed a new corneal infiltrate at the graft-host junction: Corneal scrapings were culture positive for Coniochaeta hoffmannii. This was treated with topical and intrastromal voriconazole along with oral itraconazole 200 mg once daily for 8 months. CONCLUSIONS: Coniochaeta hoffmannii may cause recalcitrant keratitis and endophthalmitis, which required longstanding antifungal treatment.

Fungal keratitis caused by Metarhizium anisopliae complex.

PURPOSE: To report a case of fungal keratitis caused by Metarhizium anisopliae complex. METHODS: Case report. RESULTS: Our patient presented with a central corneal infiltrate. Fungal culture yielded a Metarhizium species. She was started on antifungal agents with no significant improvement. A therapeutic corneal transplant was performed after perforation. At two years follow up, she was free of infection. CONCLUSION: Metarhizium anisopliae is a very rare cause of keratitis. Although previous reported cases showed clinical improvement with antifungal agents, this case required surgical treatment to control the infection.
