    Abstract:
    PURPOSE: To investigate the therapeutic efficacy and optimal drug dose of an intravitreally implantable voriconazole (VCZ) drug delivery system (DDS) in experimental endophthalmitis of Aspergillus fumigatus. METHODS: Vitrectomy was performed in albino rabbits with intravitreal inoculation of susceptible A. fumigatus. The animals were randomized into groups of control, polylactic-co-glycolic acid implantation, VCZ injection, and intravitreal VCZ DDS containing 0.5, 0.9, and 1.2 mg of VCZ, respectively. The therapeutic effect was assessed by clinical observation, histology, and microbiology. RESULTS: The inflammation in the VCZ injection and DDS groups was milder than the untreated and polylactic-co-glycolic acid groups (P ≤ 0.046). The 0.9-mg and 1.2-mg DDS groups presented milder anterior chamber and vitreous inflammation than the injection group during the first 3 weeks (P ≤ 0.044), but only the 1.2-mg DDS group had clearer vitreous thereafter (P ≤ 0.037). Smear and fungal culture showed negative results in all DDS groups. Normal histologic structure of the retina was observed in the eyes recovering from endophthalmitis. CONCLUSION: The therapeutic effect of intravitreal VCZ DDS on fungal endophthalmitis appears to be significantly better than intravitreal injection of VCZ. The optimal dose of VCZ in the DDS in this study was 1.2 mg.
