Descemet’s membrane


The basement membrane that lies between the corneal proper substance, also called stroma, and the endothelial layer of the cornea. It is composed of a different kind of collagen (Type IV) than the stroma. The endothelial layer is located at the posterior of the cornea. Descemet’s membrane, as the basement membrane for the endothelial layer, is secreted by the single layer of squamous epithelial cells that compose the endothelial layer of the cornea.

Syn: Posterior limiting lamina, posterior elastic lamina, lamina elastica posterior, and membrane of Demours.

Origin: Named after French physician Jean Descemet (1732–1810).
