Cornea7
- The corneal endothelial cell layer and its basement membrane (Descemet's membrane) act as a barrier to hydration of the corneal stroma by aqueous humor and are "pump" cells of the cornea that function to maintain hydration of the cornea at a specific level that maintains corneal stromal clarity through precise spatial arrangement of collagen fibers.
