In brief: Random eye movements

The patient experiences constant irregular rapid eye motions in random directions, often in a sudden jerking fashion (myoclonus).
This was first described in children with neuroblastomas, but has been rarely associated with problems affecting cerebellar-brainstem connections in other diseases, such as even in multiple sclerosis.
