Ten corneal specimens obtained at the time of penetrating keratoplasty for long-standing refractory Acanthamoeba keratitis were reviewed. Histopathologic findings included epithelial denudation and variable degrees of necrosis, inflammation, and cysts or trophozoites of acanthamoeba in the stroma. No blood vessels were found in the stroma despite the presence of long-standing corneal inflammation. The absence of corneal stromal neovascularization on biomicroscopic and histopathologic examination is a sign of Acanthamoeba keratitis.

D012189	Retrospective Studies	Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.

D015823	Acanthamoeba Keratitis	Infection of the cornea by an ameboid protozoan which may cause corneal ulceration leading to blindness.	Keratitis, Acanthamoeba,Acanthamoeba Keratitides,Keratitides, Acanthamoeba
D015948	Keratoplasty, Penetrating	Partial or total replacement of all layers of a central portion of the cornea.	Keratoplasties, Penetrating,Penetrating Keratoplasties,Penetrating Keratoplasty
D016510	Corneal Neovascularization	New blood vessels originating from the corneal blood vessels and extending from the limbus into the adjacent CORNEAL STROMA. Neovascularization in the superficial and/or deep corneal stroma is a sequel to numerous inflammatory diseases of the ocular anterior segment, such as TRACHOMA, viral interstitial KERATITIS, microbial KERATOCONJUNCTIVITIS, and the immune response elicited by CORNEAL TRANSPLANTATION.
