First of all, you should get to know what exactly corneal edema is. The cornea of the eyes is the media through which the eyes get enough oxygen and waters from the tears. At the same time, because the cornea is directly exposed to the outer world, it can very easily be infected, and it can take a very long time to recover. The corneal edema will cause the decrease of endothelial cells, the increase of corneal thickness, and the decline of the corneal transparency. The early state of the corneal edema is limited in the corneal epithelium, which leads to a sharp drop in the eyelight. If left untreated, the conditions of the patient can become more serious. Therefore, people who get corneal edema should get correspondent treatment in time. One of the method is to use hypertonic glycerin, hyperosmotic glucose, high permeability eye ointment and so on, to dehydrate the corneal epithelium and transfer the water into the tears. For people who get symptoms of high eye pressure, they should take active measures to decrease the eye pressure such as using
acetazolamide diamox to ease the edema. And if needed, the patient can take a transplant surgery of cornea.
