Isolated abnormalities of pursuit gaze were studied in 8 patients with unilateral acute (hemorrhage) or chronic (tumor) lesions of the parieto-occipital lobes. Ipsilateral pursuit was impaired in all patients, being superimposed with cogwheel saccades. Foveal pursuit was more disturbed than full-field pursuit. Impairment of contralateral pursuit was observed in all patients, but was severe only after acute involvement of the nondominant hemisphere. These findings provide further evidence for some asymmetric organization of hemispheric command of ocular movements. In these patients with hemianopia, the bilateral alterations of pursuit gaze probably correspond to an inter- and intrahemispheric disconnection syndrome.
对8例患有顶枕叶单侧急性（出血）或慢性（肿瘤）病变的患者进行了孤立性追踪注视异常的研究。所有患者的同侧追踪均受损，并伴有齿轮样扫视。中央凹追踪比全视野追踪受干扰更严重。所有患者均观察到对侧追踪受损，但仅在非优势半球急性受累后才严重。这些发现为眼球运动半球控制的某些不对称组织提供了进一步的证据。在这些偏盲患者中，追踪注视的双侧改变可能对应于半球间和半球内的分离综合征。
