Ocular neuromyotonia
Reviewed by Fiona Rowe

The authors report a cohort of ten patients (nine female) with ocular neuromyotonia (ONM) for clinical signs and symptoms, treatment methods and outcome. Six had affected vertical muscles including superior oblique, inferior rectus and superior rectus. Four had affected lateral rectus muscles. Episodes were predominantly every 10-40 minutes and lasting from a few seconds to minutes. Episodes were repeated and recurrent throughout the day. Two cases had previous cranial radiation, two had thyroid eye disease and one had superior oblique myokymia that progressed to ONM. Treatment was typically with carbamazepine or Gabapentin.
