On the visual disturbances associated with massive basal aneurysms.

A Fisher, R L Cooper

    Proceedings of the Australian Association of Neurologists
    |January 1, 1976
    PubMed
    Summary

    Massive basal aneurysms can cause varied visual disturbances, making diagnosis challenging. Impaired visual acuity is the most frequent defect, followed by bitemporal hemianopia and junction scotoma.

    Area of Science:

    • Neuro-ophthalmology
    • Vascular Neurology

    Background:

    • Massive basal aneurysms pose diagnostic challenges due to diverse visual pathway compromise.
    • Understanding visual defects associated with these rare aneurysms is crucial for accurate diagnosis and management.

    Observation:

    • A critical analysis of visual defects was performed in five patients with large anterior basal aneurysms.
    • These findings were correlated with existing literature, including studies by Jefferson and Bull.

    Findings:

    • Impairment of visual acuity is the most common visual defect.
    • Bitemporal hemianopia is the second most frequent visual defect.
    • Junction scotoma is the third most frequent visual defect.

    Implications:

    • This study clarifies the clinical features of visual disturbances caused by massive basal aneurysms.
    • The findings aid in diagnosing and managing patients with these rare neurological conditions.
    • Improved understanding of visual field defects can guide surgical or therapeutic interventions.
