• A model of chronic herpetic keratitis was developed by injecting rabbits subconjunctivally with a corticosteroid. A levamisole hydrochloride-treated group of these rabbits developed milder, more rapidly healing epithelial lesions than an untreated group. Although most of the untreated rabbits developed stromal disease, almost all of the lesions in the levamisole-treated animals were limited to the epithelium.
