Dancing Eye syndrome

or Opsoclonus Myoclonus Syndrome, which is a much less suggestive name, and not only a partially correct description!

Features:

  • rapid involuntary eye movements in all directions¬†(opsoclonus)

But also

  • ataxia
  • marked irritability, sleep disturbance.

Typically in young children, under 3. About half will have neuroblastoma. The rest assumed to be autoimmune.
