Abstract
Lagophthalmos is an inability to close the eyelid in a peripheral facial (VII) nerve palsy, with partial opening of the palpebral fissure. A similar phenomenon may be observed with aberrant regeneration of the oculomotor nerve, thought to be due to cocontraction of the levator palpebrae superioris and superior rectus muscles during Bell’s phenomenon.
