[Lagophthalmic keratopathy].

Exposure keratopathy is a non-infectious keratitis which follows any pathological process that limits eyelid closure, thus leaving the cornea unprotected during blinking or during sleep. Lagophthalmos is most frequently determined by peripheral facial nerve palsy and by exophthalmos/proptosis. The therapeutical approach includes both etiological and symptomatic treatment, as well as the treatment of corneal lesions, an attitude often associated with a good functional prognosis.
