[Eye movement disorders in visual agnosia]

Abstract

By the aid of photooptical methods the authors studied eye movements in 6 patients with disorders of visual gnosis due to focal lesions in the occipitallbrain lobes. The examination included studies of a fixation of immovable objects, a tracing of linear and pendulum moving objects and a voluntary change of points of fixation in space. It was demonstrated that expressed symptoms of agnosia are accompanied by defects in the organization of all forms of opticomotor activity. The authors discuss problems of the pathogenesis of oculomotor disorders in optical agnosia.
