MRCP revision battle 30.2: Oculogyric Crisis

The key features of an oculogyric crisis are restlessness and upward deviation of the eyes (although this only occurs in severe cases).

Oculogyric crises may be precipitated by a range of drugs including:
  • neuroleptics
  • metoclopramide/domperidone
  • nifedipine
  • TCA
  • carbamazepine

Several clinical conditions can also cause oculogyric crises, for example:
  • parkinsons disease
  • post encephalitis
  • bilateral thalmic infarction
  • MS

Treatment is with procyclidine, an anticholinergic.

On to the next battle...
