Blindness following tentorial herniation

J R Keane

    Summary
    This summary is machine-generated.

    Tentorial herniation can cause permanent blindness, even after treatment. Early diagnosis of brain masses using computed tomographic scans is crucial to prevent this rare neurological complication.

    Area of Science:

    • Neurology
    • Ophthalmology

    Background:

    • Tentorial herniation is a critical condition often resulting from supratentorial masses.
    • Neurological deficits can persist after surgical relief of herniation.

    Observation:

    • Seven patients experienced permanent bilateral visual loss as the primary neurological deficit post-tentorial herniation relief.
    • Causes included subdural hematomas, subdural empyemas, traumatic intracerebral hematoma, and postoperative infarction.

    Findings:

    • Optic atrophy was observed in three patients, suggesting damage to the visual pathway and posterior cerebral artery compression.
    • Computed tomographic (CT) scanning identified occipital infarction in two patients.

    Implications:

    • Early diagnosis of supratentorial masses via CT scanning is vital to prevent vision loss.
