An oculogyric crisis is the paroxysmal, involuntary upward deviation of the eyes. The eyelids are often retracted. Attacks last from a few minutes to a few hours.

It may occur in patients sensitive to:

• phenothiazines
• haloperidol
• metoclopramide

Rarely oculogyric crises are seen in cases of postencephalitic Parkinson's disease.
