Abstract
Trigeminal anesthesia yields neurotrophic keratopathy, a degenerative disease of the ocular surface that may cause corneal blindness. Concomitant paralytic lagophthalmos secondary to facial paralysis places the neurotrophic cornea at increased risk. Conservative therapies for neurotrophic keratopathy do not address its underlying pathophysiology. Nerve transfers to re-establish corneal sensory innervation have demonstrated effectiveness for therapeutic management of this challenging disease. Herein we characterize indications and surgical techniques for corneal neurotization.
