Traumatic bitemporal hemianopsia: case report

P A Tibbs, W H Brooks

    The Journal of Trauma
    |February 1, 1979

    Summary
    This summary is machine-generated.

    Traumatic optic chiasm injury causing bitemporal hemianopsia is rare after head trauma. Intrachiasmatic contusion, edema, and hemorrhage are likely causes, necessitating ophthalmologic monitoring and potential steroid treatment.

    Area of Science:

    • Ophthalmology
    • Neurology
    • Trauma Surgery

    Background:

    • Optic chiasm trauma from head injuries is infrequently documented.
    • Bitemporal hemianopsia, a specific visual field defect, can result from optic chiasm damage.

    Observation:

    • A patient presented with a hemianopic field defect 12 days post-frontal basilar skull fracture.
    • This visual impairment suggests damage to the optic chiasm.

    Findings:

    • The likely cause of the visual defect is intrachiasmatic contusion, edema, and hemorrhage.
    • The injury mechanism involves trauma to the optic chiasm within the skull base.

    Implications:

    • Early diagnosis and management of optic chiasm trauma are crucial for visual preservation.

  • Serial ophthalmologic examinations are recommended to monitor visual field changes.
  • Consideration of corticosteroid therapy may be beneficial in managing inflammation and edema.
