Topical and Oral Voriconazole in the Treatment of Fungal Keratitis

Abstract

We describe two patients with fungal keratitis refractory to standard antifungal therapy whose conditions were managed with voriconazole. The first case is a patient with endophthalmitis and corneal ulcer due to Candida parapsilosis after receiving a corneal transplant. The patient was treated with amphotericin but showed no signs of improvement. Topical voriconazole, oral voriconazole, and intravitreal voriconazole yielded signs of improvement. The second case is a 63-year-old male who underwent a month of empiric treatment with 0.2% topical amphotericin for fungal keratitis but showed no signs of improvement. Treatment was then provided with 1% voriconazole. Both cases showed effective treatment with voriconazole. Voriconazole may be considered as a new method to treat fungal keratitis refractory to standard antifungal therapy.
