[Carotid-ophthalmic aneurysms and visual abnormalities].

    Summary

    Directly clipping carotid-ophthalmic aneurysms is risky. Visual problems are common with these aneurysms, and surgical outcomes vary, with some patients improving after optic nerve decompression.

    Area of Science:

    • Neurosurgery
    • Vascular Neurology
    • Ophthalmology

    Context:

    • Carotid-ophthalmic aneurysms pose unique surgical challenges due to their anatomical location near critical structures.
    • Visual abnormalities are a significant clinical manifestation associated with these aneurysms.

    Purpose:

    • To analyze the incidence and characteristics of visual abnormalities in patients with carotid-ophthalmic aneurysms.
    • To evaluate surgical outcomes and their impact on visual function following treatment.

    Summary:

    • Thirty patients with 33 carotid-ophthalmic aneurysms were studied, with 10 experiencing preoperative visual deficits.
    • Visual acuity and visual field defects were common, often progressive in intact aneurysms and sudden in ruptured cases.
    • Surgical intervention in 7 patients resulted in visual improvement in 3 cases with successful optic nerve decompression, while 2 deteriorated due to direct clipping complications.

    Impact:

    • Highlights the risks associated with direct clipping of carotid-ophthalmic aneurysms.
    • Emphasizes the importance of careful surgical technique to preserve or improve visual function.
    • Underscores the link between aneurysm projection and the occurrence of visual symptoms.
