IN THE case reported in the preceding section, a persistent and systematic alteration in visual space perception was described in a case in which (consequent to a shrapnel injury of the posterior portion of the right parietal lobe) hemiparesis had developed but practically normal fields of vision were observed on standard perimetric examination. In the following case, an almost identical disorder in the perception of spatial relations was observed in a patient with shrapnel injuries of the occipital lobe. In contrast to the first case, the injury resulted in demonstrable homonymous field defects, but was not accompanied with any further changes in sensory or motor function.
