Acute Upgaze Deviation

    • Sudden involuntary upgaze of both eyes
    • May be episodic or sustained
    • Common causes: syncope, seizure, dystonic reaction to neuroleptics (“oculogyric crisis”), isolated benign developmental disorder in otherwise normal neonates
    • Uncommon causes: habit spasm (tic disorder), carbamazepine toxicity, hypoxic encephalopathy
    • Core neuro-ophthalmic feature
      • Upgaze of both eyes of variable duration
    • Possible accompanying clinical features
      • Recent exposure to neuroleptic agents or carbamazepine, evoking an “oculogyric crisis”
      • Dystonic facial and/or extremity postures, forced thoughts or emotions as part of an “oculogyric crisis”
      • Involuntary movements of the face or extremities called “habit spasms” or “tic disorder”
      • Tonic–clonic extremity movements as part of a seizure
      • Flapping wrist flexion tremor (“asterixis”) in hypoxic-ischemic, post-infectious, paraneoplastic, or metabolic encephalopathy
      • Ocular bobbing in hypoxic-ischemic encephalopathy or metabolic encephalopathy
      • No accompanying clinical manifestations when this is a developmental disorder in normal neonates
    • Imaging features
      • Usually normal
      • Multifocal cerebral, brainstem, cerebellar restricted diffusion in hypoxic-ischemic encephalopathy
      • Brainstem signal abnormalities in ocular bobbing
    • Psychogenic upgaze deviation
    • Look for accompanying manifestations in order to make an organic diagnosis
    • Depends on the underlying condition
    • Should resolve within months if this is an isolated manifestation in otherwise normal neonates
