    This study details a rare case of acute multiple sclerosis (MS) presenting with vision loss and leg symptoms. Small arteriolar disease was observed, suggesting a novel pathway in MS pathogenesis.

    Area of Science:

    • Ophthalmology
    • Neurology
    • Vascular Biology

    Background:

    • Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease of the central nervous system.
    • Typical MS presentations involve neurological deficits, but retinal vascular involvement is less common.

    Observation:

    • A 25-year-old male presented with acute MS symptoms including unilateral blindness, urinary difficulty, and lower limb paresthesias/weakness.
    • Ophthalmic examination revealed retinal ischemia due to superior temporal arteriole occlusion, optic disc edema, and periphlebitis.

    Findings:

    • Retinal signs resolved within three weeks, leaving persistent optic disc pallor.
    • The presence of small arteriolar disease in this MS case is an unusual finding.

    Implications:

    • This case highlights a potential, less-recognized pathogenetic mechanism in multiple sclerosis.
    • Further research into small vessel disease may offer new therapeutic targets for MS.
