摘　　要：目的　观察视神经病变患者视锥细胞颜色视觉运动觉的变化。方法　分别应用蓝、绿条状视标显示在黄、紫色背景上,保持视标与背景间存在着亮度对比,以分离检查26眼视神经病变蓝及绿视锥细胞的视觉运动觉功能。结果　视神经病变患者蓝、绿视锥细胞视觉运动觉的位移和闪烁阈值为1.78mm±0.49mm、0.44±0.38、1.72mm±0.63mm、0.32±0.33,分别与正常值0.57mm±0.24mm、0.96±0.09、0.71mm±0.37mm、0.89±0.18比较,均具有显著性差异(P<0.001)。结论　蓝及绿视锥细胞的视觉运动觉是反映视神经病变早期视功能损害的一个重要指标。Objective In order to assess the change of cone's color motion perception in neuropathy.Methods Motion perceptions of blue,green cones of 26 neuropathy were isolated by blue,green vertical line stimulus displayed on the yellow,purple background respectively and there were luminance contrast between stimulus and background.Results The displacement threshold and flicking threshold of motion perception from blue,green cones in neuropathy were 1.78mm±0.49mm,0.44±0.38,1.72mm±0.63mm,0.32±0.33,compared with the normal group 0.57mm±0.24mm,0.96±0.09,0.71mm±0.37mm,0.89±0.18 respectively,there were obviously differences between them( P <0.001).Conclusions Blue and green cones' motion perception may reveal visual nerve damage in early neuropathy.
