Clinical features and prognosis of Miller Fisher syndrome.

The authors reviewed the clinical features and outcome of Miller Fisher syndrome (MFS) for 50 consecutive patients with MFS including 28 patients who received no immunotherapy. Besides the characteristic clinical triad (ophthalmoplegia, ataxia, and areflexia), pupillary abnormalities, blepharoptosis, and facial palsy are frequent in MFS, whereas sensory loss is unusual despite the presence of profound ataxia. Patients with MFS usually had good recovery and no residual deficits.
