Marginal keratitis is an inflammation of the cornea characterized by reduced vision, a painful red eye, sensitivity to light, foreign body sensation, and a mucopurulent discharge. It is a common, transient, usually unilateral condition that may be associated with chronic staphylococcal blepharitis. Patients presenting with the above listed symptoms should be referred to an ophthalmologist for a diagnosis. Marginal keratitis can be successfully treated using topical steroids.
