DUANES-SYNDROME WITH TRIGEMINAL NERVE INVOLVEMENT

A patient with Duane's syndrome and congenital sensory dysfunction of the ipsilateral trigeminal nerve is presented. Electrophysiological st udies of trigeminal function did not reveal any abnormalities. Hypopla sia of the caudal spinal trigeminal tract is the most likely underlyin g pathology. Duane's syndrome results from abnormal embryological deve lopment of the oculomotor nerves and may occasionally affect other cra nial nerves. Involvement of the trigeminal nerve, however, has not bee n reported previously.
