目的:确定正常人在不同运动速度绿、红光栅刺激时的等亮度点值,探讨色觉和运动觉相互作用特性。方法:自行研制能同时诱发运动觉和色觉的运动颜色光栅刺激器,用眼电图(electrooculograph,EOG)方法记录诱发视动性眼球震颤(optokinetic nystagmus,OKN),确定不同运动速度时受检查者OKN换相时的绿、红亮度比值(即等亮度点)。共测试16例(32只眼)正常人,男6人,女10人,年龄20～51岁。结果:于5个等级光栅运动速度:595,400,301,239和200mm/s,测得其对应等亮度点的均值分别为:0.525,0.425,0.397,0.391,0.367。经统计学分析,595mm/s组的等亮度点均值与其他各组间有非常显著性差异(P<0.01),其他组间的等亮度点均值均无显著性差异(P>0.05)。结论:运动速度快的情况下会影响人眼对颜色的感觉。眼科学报1997;13:186—188。
OBJECTIVE: To determine the equivalent brightness points of normal subjects at different green and red grating motions, and to explore the interaction between color vision and motor activity. Methods: A kinematic color grating stimulator that can induce both motion and color vision was developed. The optokinetic nystagmus (OKN) was recorded by electrooculography (EOG), and the subjects under different motion velocities OKN green, red when commutating brightness ratio (ie, the same brightness point). A total of 16 cases (32 eyes) were normal, 6 males and 10 females, aged 20 to 51 years. Results: At 5 levels of raster motion speed: 595, 400, 301, 239 and 200 mm / s, the corresponding mean brightness values were 0.525,0.425,0.397,0.391,0.367 respectively. The statistical analysis showed that the average brightness at 595mm / s group was significantly different from other groups (P <0.01), but there was no significant difference among the other groups (P> 0.05). Conclusion: The fast moving speed will affect the human eye to the feeling of color. Journal of Ophthalmology 1997; 13: 186-188.
