Sudden monocular visual loss in pseudotumor cerebri.

B T Troost, R L Sufit, M G Grand

    Archives of Neurology
    |July 1, 1979
    PubMed
    Summary

    Sudden vision loss in patients with benign intracranial hypertension may not stem from intracranial pressure. Prompt neuro-ophthalmologic evaluation is crucial to identify other causes, such as subretinal neovascular membranes, for effective treatment.

    Area of Science:

    • Neuro-ophthalmology
    • Medical research

    Background:

    • Benign intracranial hypertension (BIH) can cause papilledema.
    • Sudden monocular visual loss is a concerning symptom in patients with BIH.

    Observation:

    • A patient with BIH and papilledema experienced sudden, painless monocular visual loss.
    • Initial treatment focused on reducing intracranial pressure due to fear of further visual deterioration.

    Findings:

    • Neuro-ophthalmologic evaluation revealed the visual loss was caused by a subretinal neovascular membrane, not solely intracranial pressure.
    • Vision improved, papilledema resolved, and headaches ceased after discontinuing medical therapy for intracranial pressure.

    Implications:

    • In cases of minimal papilledema, sudden visual deterioration warrants a thorough search for alternative causes beyond elevated intracranial pressure.
    • This case highlights the importance of comprehensive neuro-ophthalmologic assessment to avoid potentially unnecessary treatments for intracranial hypertension.
