PURPOSE: To analyze effects of isosorbide dinitrate (DNI) on corneal hyperalgesia and neutrophil infiltration in an experimental model of superficial keratitis induced by lipopolysaccharide (LPS). METHODS: Hyperalgesia was studied through the induction of inflammatory keratitis in rats (n=60), by corneal exposure to LPS. Following exposure, the inflamed eye was treated for four days, with one of the following solutions: topical DNI (200 μg, 65 μg and 20 μg), prednisolone 1% (PRED), and vehicle. Saline-exposed eyes (LPS -) underwent the same […]
