Gross and microscopic features of the post-mortem eyes. (A) The anterior surface of the iris is smooth and lacks normal architectural landmarks, including crypts, contraction furrows, and collarette. (B) A cleft (arrow) separates the two layers of the iris stroma. The anterior layer of the iris stroma (asterisk) lacks the iris pigment epithelium. (C) Anterior segment at a scanning magnification manifests the incompletely cleaved anterior chamber angle with peripheral iridocorneal attachment (arrow) and a central duplication of the iris stroma (hematoxylin–eosin stain; original magnification ×5). (D) The anterior layer of the duplicated iris stroma is composed of thick-walled iris stromal blood vessels surrounded by the normal iris stromal constituents and lacks the smooth muscle and iris pigment epithelium. A cleft separates the anterior duplicated iris stroma from the underlying iris tissue with smooth muscle (arrow) and iris pigment epithelial bilayer (arrowhead) (hematoxylin–eosin stain; original magnification ×50). (E) The crystalline lens demonstrates fragmentation and liquefaction of cortical lens fibers (arrow), compatible with cataract formation (hematoxylin–eosin stain; original magnification ×25). (F) The ciliary body processes are markedly hypoplastic (arrow).
