Oculogyric crisis (OGC) is a rare sudden, paroxysmal, dystonic reaction that may manifest in response to specific drugs, particularly neuroleptics, or medical conditions, such as movement disorders. This neurological phenomenon is characterized by a sustained dystonic, conjugate, involuntary upward deviation of both eyes lasting seconds to hours. The term oculogyric is applied in reference to the simultaneous upward movement of both eyes, although the reaction may encompass a variety of additional responses.[1] The reaction is not life-threatening.[2]
For clarification, oculogyric seizures, also termed versive seizures, represent one of the manifestations of epilepsy. These seizures exhibit the same upward eye movement observed in OGC but are classified as a specific subtype of epilepsy.[3]
