Cornea 552 Exposure Keratitis Definition

Keratitis resulting from drying of the cornea in the case of lagophthalmos.

Epidemiology: Exposure keratitis is a relatively frequent clinical syndrome. For example, it may occur in association with facial paralysis following a stroke.

Etiology: Due to facial nerve palsy, there is insufficient closure of the eyelids over the eyeball (lagophthalmos), and the inferior third to half of the cornea remains exposed and unprotected (exposure keratitis). Superficial punctate keratitis (see above) initially develops in this region and can progress to corneal erosion (see Fig. 18.5) or ulcer.
