6只新西兰兔进行了视网膜光损伤的实验。每只免的一眼接受间接检眼镜光照(视网膜幅照度为318mw/cm~2)1小时,另一眼作对照,比较了照光前,照光后1,6小时,1,2,3,7,10,20利30天的照光眼组和对照组的暗适应视网膜电图 a 波和 b 波振幅差,结果表明照光后1小时,于各种刺激光条件下照光眼组的视网膜电图 a 波和 b 波振幅较对照组降低,其中由Ⅰ_1强度蓝光和Ⅰ_(16)强度白光刺激引出的 a波和 b 波振幅差在二组间均有显著性意义(P<0.05),6小时后,照光眼组的振幅已恢复,以后各时间照光眼组的振幅与对照眼组相接近,自6小时后,统计学上二组间振幅差均无显著性差异(P>0.05)。
Six New Zealand rabbits were tested for retinal photodamage. Each of them received an indirect ophthalmoscope at a light exposure (retina amplitude of 318mw / cm ~ 2) for 1 hour, while the other as a control, compared with the light before the light after 1,6 hours, 1,2,3,7,10 , The 20-day and 30-day illumination of the eye group and the control group of dark adaptation of the a-wave and b-wave amplitude difference, the results show that one hour after illumination, under various stimulating light conditions, the electroencephalogram a wave and The amplitude of b wave was lower than that of the control group. The difference of a wave amplitude and b wave amplitude induced by Ⅰ_ (Ⅰ) intensity blue light and Ⅰ_ (16) white light stimulus was significant between the two groups (P <0.05). After 6 hours, The amplitude of the ocular group has been restored. After that, the amplitude of the oculomotor group is similar to that of the control group. After 6 hours, there is no significant difference in amplitude between the two groups (P> 0.05).
