The bias of slow phase velocity (SPV) of optokinetic nystagmus (OKN) caused by an acute labyrinthine lesion was examined in 8 patients using differnet optokinetic stimulus velocities. In all patients a directional preponderance of OKN-SPV was found corresponding to spontaneous nystagmus. This was due to enhancement of nystagmus SPV to the side of the lesion and depression of SPV in the opposite horizontal direction. The preponderance of OKN on the average increased with the intensity of spontaneous nystagmus and decreased along with recovery. These vestibularly induced differences in OKN-SPV range up to 70%. A differentiation is discussed between OKN preponderances caused by labyrinthine lesions and brain stem lesions.
我们使用不同的视动刺激速度，对8例急性迷路病变患者视动性眼震（OKN）慢相速度（SPV）的偏差进行了检查。在所有患者中，均发现OKN-SPV的方向优势与自发性眼震相对应。这是由于眼震SPV向病变侧增强，而在相反水平方向的SPV降低。OKN的优势平均随自发性眼震强度增加而增加，并随恢复而降低。这些前庭诱发的OKN-SPV差异高达70%。本文讨论了迷路病变和脑干病变引起的OKN优势之间的区别。
