Localization in impaired spatial vision

The present study provides clear clinico-anatomical evidence for localization of the spatial vision pathway. We report the case of a 29-year-old woman with severe spatial vision impairment. Magnetic resonance imaging revealed distinct bilateral and symmetrical occipito-parietal damage. The right lesion affected the superior parietal lobule, the dorsolateral portion of the occipital lobe, the precuneus, and the cuneus. The left lesion affected the superior parietal lobule, the dorsolateral portion of the occipital lobe, the precuneus, an upper part of the cuneus, and the posterior portion of the middle and inferior temporal gyri.
