Keratitis is an inflammation of the cornea—the domed, transparent circular portion of the front of the eyeball that lies over the pupil. There are several types, including: Superficial Punctate Keratitis- typically seen in dry eye. Interstitial Keratitis- typically seen in various infections. Herpes Simplex Viral Keratitis- a common virus affecting millions. Traumatic Keratitis- results when a corneal injury leaves scar tissue.
