Dynamic regulation of barrier integrity of the corneal endothelium
WebThe transparency of the cornea stroma is dependent on the tissue hydration. The stroma is composed of 200 or more lamellae, 2-μm thick with widths varying from 10 to 250 μm that span from limbus to limbus and overlap each other at varying orientations. The total thickness of the human stroma varies from 450 to 550 μm.
