Visual dysfunctions in optic tract lesions.

M B Bender, I Bodis-Wollner

    Annals of Neurology
    |March 1, 1978
    PubMed
    Summary
    This summary is machine-generated.

    Neoplasms and aneurysms affecting the optic tract commonly cause blurred vision and optic atrophy. These conditions can lead to varied visual field defects and reduced visual acuity in patients.

    Area of Science:

    • Neuro-ophthalmology
    • Neurology
    • Oncology

    Background:

    • Optic tract lesions, including neoplasms and aneurysms, can present with diverse visual disturbances.
    • Understanding these visual manifestations is crucial for early diagnosis and management.

    Purpose of the Study:

    • To summarize characteristic visual symptoms and signs in patients with optic tract neoplasms or aneurysms.
    • To correlate visual findings with underlying pathologies.

    Main Methods:

    • Retrospective review of 12 patients with optic tract neoplasms or aneurysms.
    • Detailed analysis of presenting visual symptoms, visual acuity, visual fields, and funduscopic findings (optic atrophy).
    • Correlation of visual deficits with imaging and clinical data.

    Main Results:

    • Blurred vision was the most frequent initial symptom.
    • Optic atrophy was observed in 7 out of 12 patients.
    • Visual field defects included uniocular central scotomas, homonymous scotomas, and incongruous/incomplete field combinations.

    Conclusions:

    • Optic tract neoplasms and aneurysms present with a spectrum of visual impairments.
    • Early detection of visual changes is vital for timely intervention.
    • Associated endocrine and cognitive deficits may occur.
