Descemet's membrane

It is composed of different kinds of collagen (Type IV and VIII)[1] than the stroma.

[2] The corneal endothelium is a single layer of squamous cells covering the surface of the cornea that faces the anterior chamber.

Significant damage to the membrane may require a corneal transplant.

Damage caused by the hereditary condition known as Fuchs dystrophy (q.v.

[3] In the process most of the squamous cells of the donor membrane survive to dramatically and emphatically reverse the corneal deterioration (see DMEK surgery).
