New findings in posterior amorphous corneal dystrophy. 1984

S P Dunn, and J H Krachmer, and S S Ching

Eight members of a family spanning five generations were found to have posterior amorphous corneal dystrophy. This rare abnormality was noted in both its centroperipheral and peripheral forms. The following five heretofore unrecognized features were noted: (1) hyperopia, (2) flattened corneal topography, (3) anterior iris surface and stromal abnormalities, (4) fine iris processes extending to Schwalbe's line for 360 degrees, and (5) extension of the opacity to the limbus. The presence of this dystrophy in a 6-month-old family member further suggests the possibility that it is a congenital abnormality.

D007498	Iris	The most anterior portion of the uveal layer, separating the anterior chamber from the posterior. It consists of two layers - the stroma and the pigmented epithelium. Color of the iris depends on the amount of melanin in the stroma on reflection from the pigmented epithelium.

D003315	Cornea	The transparent anterior portion of the fibrous coat of the eye consisting of five layers: stratified squamous CORNEAL EPITHELIUM; BOWMAN MEMBRANE; CORNEAL STROMA; DESCEMET MEMBRANE; and mesenchymal CORNEAL ENDOTHELIUM. It serves as the first refracting medium of the eye. It is structurally continuous with the SCLERA, avascular, receiving its nourishment by permeation through spaces between the lamellae, and is innervated by the ophthalmic division of the TRIGEMINAL NERVE via the ciliary nerves and those of the surrounding conjunctiva which together form plexuses.

D003317	Corneal Dystrophies, Hereditary	Bilateral hereditary disorders of the cornea, usually autosomal dominant, which may be present at birth but more frequently develop during adolescence and progress slowly throughout life. Central macular dystrophy is transmitted as an autosomal recessive defect.
