Corneal Sensitivity After Trigeminal Block

  • Jörg Draeger

Abstract

The loss of corneal reflex and the subsequent neuroparalytic keratitis are of clinical importance in a patient with trigeminal neuralgia in whom the fifth nerve has been surgically severed. Trigeminal neuralgia is characterized by exquisitely painful attacks which often last only a few seconds, but may recur up to a hundred times a day. The attacks may be triggered by chewing or talking (trigger points). In secondary trigeminal neuralgias the etiology can easily be determined (e.g. tumors of the cerebellopontine angle, herpes zoster, multiple sclerosis); no etiology is found in cases of idiopathic trigeminal neuralgia (i.e. typical or genuine neuralgia). Most frequently affected are the second and third branches of the trigeminal nerve.
