Dysconjugate gaze in hepatic coma

L R Caplan, D Scheiner

    Annals of Neurology
    |September 1, 1980
    PubMed
    Summary
    This summary is machine-generated.

    Hepatic encephalopathy can cause eye movement abnormalities, including divergence at rest and dysconjugate gaze. This rare oculomotor dysfunction in metabolic encephalopathy highlights potential neurological effects.

    Area of Science:

    • Neurology
    • Ophthalmology

    Background:

    • Metabolic encephalopathy, a condition affecting brain function due to metabolic disturbances, can manifest with diverse neurological symptoms.
    • Oculomotor dysfunction is an uncommon but recognized complication of metabolic encephalopathy.

    Observation:

    • An elderly female patient experiencing hepatic encephalopathy presented with specific eye movement abnormalities.
    • The patient exhibited ocular divergence at rest and dysconjugate gaze following caloric stimulation.

    Findings:

    • The observed oculomotor dysfunction, including ocular divergence and dysconjugate gaze, was directly associated with an episode of hepatic encephalopathy.
    • These findings suggest a potential link between metabolic disturbances affecting the liver and the control of eye movements.

    Implications:

    • This case underscores that metabolic encephalopathy, even without apparent structural brainstem lesions, can lead to significant oculomotor deficits.
    • Further research may elucidate the precise mechanisms by which metabolic derangements impact the brainstem pathways controlling ocular motility.
