Abstract
Purpose: To evaluate the efficacy of newly developed antifungal agents caspofungin and voriconazole in Candida albicans endophthalmitis in rabbit eyes. Methods: Thirty New Zealand white rabbits were divided into four treatment groups and one control group. One eye of each rabbit was infected by inoculation of 1 × 104 CFU/ml of C. albicans. Seventy-two hours after the inoculation, caspofungin 100 μg/0.1 ml in group 1 (n = 6), voriconazole 50 μg/0.1 ml in group 2 (n = 6), amphotericin B 10 μg/0.1 ml in group 3 (n = 6), itraconazole 10 μg/0.1 ml in group 4 (n = 6), and 0.1 ml NaCl 0.9% in control group (n = 6) were injected into the vitreous cavity. Clinical and histopathologic examination scores and microbiological analysis of vitreous aspirates were compared. Results: There was statistically significant difference in the clinical scores, histopathologic scores, and mean CFU/ml between the treatment and control groups (p < 0.05). In caspofungin and voriconazole groups, histopathologic scores and mean CFU were lower than other treatment groups and control group. Conclusions: Intravitreal injection of caspofungin and voriconazole was effective against C. albicans endophthalmitis in this experimental rabbit model.
