What does corneal edema mean?
Corneal edema, also called corneal swelling, is a buildup of fluid in your cornea, the clear lens that helps focus light onto the back of your eye. One common cause of corneal edema is a problem that affects the inner layer of your cornea. In most normal eyes, membrane called endothelium pumps fluid out of the cornea.
Is corneal edema curable?
When corneal edema is caused by an underlying disease, treatment of that disease might improve or completely cure edema. Some types of infections such as herpes simplex stromal keratitis may cause corneal edema, and the use of corticosteroid eye drops can heal edema while treating the infection.
