Keratitis is the inflammation of the front part of the eye, also known as the cornea. Most time the infection will begin in the outer layer of the cornea and can move deeper. The deeper it spread the greater the risk of impaired vision. Most experience moderate to intense pain. Depending on the cause of the inflammation the duration of it can be brief or long lasting and reoccurring. Worst possible case it can result in the loss of sight and permanent damage
There are several causes ranging from types of infections, dry eyes, injury, and other underlying medical diseases. An example of an infectious cause would be if you have or had herpes simplex virus, or an upper respiratory infection.
