Relapsing ophthalmoparesis-sensory neuropathy syndrome.

We studied two patients with recurrent sensory neuropathy and weakness of extraocular muscles. There was electrophysiologic evidence of multifocal demyelination of sensory nerves, with relative sparing of somatic motor nerves. Sural nerve biopsy in one patient showed segmental demyelination. We believe that these patients had an unusual form of inflammatory polyneuropathy--possibly a relapsing variant of the Miller-Fisher syndrome of acute idiopathic polyneuritis.
