Types
Superficial keratitis involves the superficial layers (i.e. the epithelium) of the cornea. After healing, this form of keratitis does not generally leave a scar.
Deep keratitis involves deeper layers of the cornea (i.e. The epithelium, Bowman's Membrane and often stroma), and the natural course leaves a scar upon healing that impairs vision if on or near the visual axis. This can be reduced or avoided with the use of topical corticosteroid eyedrops.
