Non-traumatic Alternaria keratomycosis in a rigid gas-permeable contact lens patient

摘要

Alternaria encompasses nearly 50 species of ubiquitous, saprophytic, dematiaceous asco-mycetes that are normal conjuctival flora in some individuals but can also cause opportunistic corneal infections, especially in the settings of agricultural trauma, surgery and topical steroid and antibiotic use. Soft contact lens wear may confer an additional risk of fungal keratitis but is rarely implicated with Alternaria,Here, we report the first case, to our knowledge, of non-traumatic, RGP-related Alternaria keratomycosis. Of 62 published cases of Alternaria keratomycoses (table 1), none involved rigid gas-permeable contact lens (RGP) wear.
