a thickening of the cornea may indicate swelling swelling usually occurs from damage to the back the layer of the cornea associated with aging trauma or disease of the eye the swelling can be observed for progression or medically treated with topical hyper osmotic agents
The cornea works like a powerful refracting medium, contributing to the focusing power of the eyes. It is kept clear by pumping of water from the endothelium layer. When there is water retention in the cornea area, it causes corneal swelling, which leads to corneal edema.To keep the cornea dry and clear, the endothelium cells regularly drive out fluids from the cornea. This endothelium is made of a single layer of cells.These cells do not regenerate when injured.he cornea works like a powerful refracting medium, contributing to the focusing power of the eyes.
