Ophthalmoparesis may be observed in up to 25% of patients with GBS. Limitation of eye movement most commonly results from a symmetrical palsy associated with cranial nerve VI. Ptosis from cranial nerve III (oculomotor) palsy also is often associated with limited eye movements. Pupillary abnormalities, especially those accompanying ophthalmoparesis, are relatively common as well. Papilledema secondary to elevated intracranial pressure is present in rare cases. Tonic pupils have been reported but only in severe cases.
