Optokinetic nystagmus (OKN) was tested in 15 patients with unilateral strictly occipital brain lesions and complete homonymous hemianopia and compared with findings in a group of normal controls. Quantitative analysis of the results in the patients revealed a bilateral disorder of OKN. When the stimulus was moved in the direction opposite to the hemianopic field, there was a significant decrease in optokinetic gain, and the amplitude of nystagmus decreased. There was no correlation between OKN and size of the residual macular field.
对15例单侧枕叶脑病变且完全性同侧偏盲患者进行了视动性眼震（OKN）测试，并与一组正常对照者的结果进行比较。对患者结果的定量分析显示OKN存在双侧障碍。当刺激物向与偏盲视野相反的方向移动时，视动增益显著降低，眼震幅度减小。OKN与残余黄斑视野大小之间无相关性。
