• Trophozoites and cysts of amebas were found within the necrotic cornea of an enucleated eye. The organism was identified, by indirect immunofluorescent staining using specific antiserum, to be Acanthamoeba castellani. This case report illustrates the difficulty of clinical diagnosis and typical inefficacy of medical therapy shown in other reports of this rare keratitis.
