Trauma-induced altitudinal hemianopsia.

S B Eiden, C L Barron

    Journal of the American Optometric Association
    |June 1, 1987

    Summary
    This summary is machine-generated.

    Traumatic brain injury can cause vision loss by damaging the occipital cortex and leading to anterior ischemic optic neuropathy. This case highlights visual field defects and reduced acuity following a car accident.

    Area of Science:

    • Ophthalmology
    • Neurology
    • Trauma Research

    Background:

    • Automobile accidents can cause significant physical trauma, including to the visual system.
    • Understanding the pathways of visual processing is crucial for diagnosing and treating vision loss.

    Observation:

    • A 55-year-old female experienced bilateral inferior altitudinal visual field defects post-trauma.
    • The patient presented with reduced visual acuities and optic disc pallor in both eyes.

    Findings:

    • Diagnostic data indicated primary damage to the occipital cortex, the brain's visual processing center.
    • A secondary complication of bilateral anterior ischemic optic neuropathy was suspected.

    Implications:

    • This case underscores the complex impact of traumatic brain injury on visual pathways.
