Helminthosporium corneal ulcers.

Two cases of fungal corneal ulcer caused by Helminthosporium are discussed. Dematiacious fungi are pigmented filamentary molds of which Helminthosporium is representative. Ulcers due to such dematiacious fungi seem to have a better prognosis than other types of fungal corneal ulcers. The importance of classifying fungal ulcers is emphasized. Therapy is considered for these keratomycoses.
