  • Title: Left Superior Homonymous Quadrantanopia due to Giant Virchow-Robin Space.
    Author: Lim M, Micieli JA.
    Journal: Case Rep Ophthalmol; 2023; 14(1):274-277. PubMed ID: 37465118.
    Abstract:
    A 51-year-old man was referred by his optometrist for an incidental finding of a visual field defect. Humphrey 24-2 SITA-Fast visual field testing revealed a left superior homonymous quadrantanopia, and magnetic resonance imaging of the brain showed a 2.0 × 0.5-cm oblong-shaped cerebrospinal fluid space posterior to the right basal ganglia. This space coursed close to the lateral geniculate body and was thought to represent a giant perivascular (Virchow-Robin) space. This case demonstrates that patients with a visual field defect without other neurological symptoms could be a result of an enlarged Virchow-Robin space along the visual pathway.
