Descemet's Membrane
Descemet's Membrane (pronunciation: /dɛsˈmeɪz ˈmɛmbreɪn/) is a thin, tough, clear layer of tissue in the cornea of the human eye. It is named after French physician Jean Descemet, who first described it in detail in the 18th century.
Etymology
The term "Descemet's Membrane" is derived from the name of its discoverer, Jean Descemet. Descemet was a French physician and anatomist who made significant contributions to the field of ophthalmology.
Description
Descemet's Membrane is the basement membrane that lies between the stroma and the endothelial layer of the cornea. It is composed of collagen and other proteins, and serves as a protective barrier for the cornea. It is also involved in the repair process when the cornea is injured.
