Helminthosporium corneal ulcers.

We studied four cases of Helminthosporium corneal ulcers from four different institutions. One case occurred in an immune-deficient infant, another in a patient three months after removal of a foreign body; the third case occurred in a patient with a corneal dystrophy who was wearing soft contact lenses and using topical corticosteroids; and the fourth occurred in a patient with a history of multiple foreign bodies. Antifungal sensitivities were performed in three cases and showed relatively good sensitivity to available antifungal medications; even though all four patients improved, there was poor correlation between in vitro sensitivities and clinical response.
