title: Anomalous effect of subconjunctival miconazole on Candida albicans keratitis in rabbits.
abstract: After intrastromal injection of a standardized inoculum of Candida albicans blastoconidia in Dutch-belted rabbits, the efficacy of subconjunctival therapy with amphotericin B and miconazole was evaluated using a quantitative isolate recovery technique. The subconjunctival injection of miconazole resulted in the recovery of significantly more viable organisms compared to the number recovered in controls (2,000 micrograms daily, P less than .02; 3,000 micrograms daily, P less than .01, respectively). Amphotericin B, in contrast, in dosages of 500 or 1,500 micrograms daily, had a significant therapeutic effect (P less than .03). The anomalous response to subconjunctival therapy with miconazole seen in this model suggests an effect on host defense mechanisms.
