Ocular Toxicity of Topical Antifungal Agents

Abstract
• We studied, in a rabbit, the ocular toxicity of topical 1% solutions or suspensions of amphotericin B, flucytosine, miconazole nitrate, and ketoconazole. Flucytosine, miconazole, and ketoconazole did not retard the closure of 8.5-mm corneal epithelial defects; amphotericin B greatly retarded the closure of such defects. Amphotericin B produced dramatic pathologic changes in this model; these changes worsened with each day of therapy. Ketoconazole produced modest biomicroscopically and histologically detectable pathologic changes in the regenerating corneal epithelium; flucytosine and miconazole did not produce such changes.
