Use of fluconazole in the treatment of candidal endophthalmitis.

Candidal endophthalmitis is a sight-threatening ocular infection that most frequently occurs as a complication of candidemia. While amphotericin B is considered the gold standard for the treatment of most invasive fungal infections, the optimal management of candidal endophthalmitis has not been determined. Fluconazole, a triazole antifungal agent, has been shown to be effective in the management of a number of invasive fungal infections in both immunocompromised and immunocompetent hosts. We describe the clinical features and outcomes for six patients with candidal endophthalmitis who were treated with fluconazole at our institutions, and we review 21 additional cases reported in the English-language literature. In total, fluconazole has been used as the sole therapy for candidal endophthalmitis in 14 patients; 16 eyes were infected. Endophthalmitis was cured in 15 of 16 eyes (94%), including five infections that were complicated by vitreitis. Successful treatment required the administration of fluconazole (100-200 mg po) daily for approximately 2 months. In addition, fluconazole has been used in combination with pars plana vitrectomy for the successful treatment of four cases of candidal endophthalmitis that were complicated by moderate to severe vitreitis. Fluconazole appears to be a safe and effective alternative or addition to conventional treatments for the management of candidal endophthalmitis. Prospective evaluation is required to more clearly define the role of this antifungal agent in the management of ocular infections due to Candida species.
