Acanthamoeba keratitis. (A) Photograph depicting the two peripheral corneal-ring infiltrates (arrows) in this patient. (B) Low magnification photomicrograph of H&E stained corneal epithelium scraped from the areas of infiltrates shown in panel (A). A double-walled cyst characteristic of Acanthamoeba is appreciated against the cellular background. (C) Higher magnification views of the cyst at two focal planes demonstrate the presence of the Acanthamoeba exocyst (double arrow head), endocyst (single arrowhead), and nucleolus (arrow).
