    Herpes Simplex (Disciform Keratitis)

    Disciform keratitis is a form of herpes simplex infection manifest as a disc-shaped, local area of corneal edema and haze accompanied by anterior uveitis. It occurs in patients who have had dendritic keratitis previously (which is due to live, replicating virus), but, in some patients, dendritic keratitis may not have been recognized because they were not evaluated at the time it was active. Disciform keratitis probably represents an immunologic response to dead virus.
