描述了五名患有视神经共济失调和触觉失用症的患者。他们还表现出在视觉引导下手指运动的困难。 CT 扫描显示，其中 3 例病变位于后顶叶区域，2 例病变位于前部。众所周知，后顶叶区域的病变可能会导致视觉引导运动的破坏。根据这两个病例，推测病变位于更靠前的位置时也可能发生相同的现象。假设视神经共济失调可能发生在顶枕区损伤或其枕额连接破坏之后。 (C) 1998 Elsevier Science B.V.
Five patients with optic ataxia together with tactile apraxia are described. They also demonstrated difficulty in finger movements under visual guidance. The CT scan showed lesions in the posterior parietal region in three and in two they were located anteriorly. It is well recognised that lesions in the posterior parietal area may cause disruption of visual guided movements. On the basis of the two cases it is postulated that the same phenomenon could occur with lesions located more anteriorly. The assumption is that optic ataxia may occur either following damage to the parieto-occipital region or to disruption of its occipitofrontal connections. (C) 1998 Elsevier Science B.V.
