近视眼儿童的增加与有机磷农药慢性中毒有关的报告已引起人们的注意。另有人记录有机磷慢性中毒者的ERG,发现a波潜伏期延长。由此,为了瞭解近视眼、有机磷农药及ERG之间的关系,作者特记录6～19岁近视眼学生的ERG,测量a波峰值时间及波动电位(O_1、O_2、O_3及O_4)平均值,并与正视眼儿童的ERG作了比较。ERG记录前充份扩瞳,于暗适应15分钟后进行。刺激光源距眼前30cm,强度为20焦耳。有效电极用白金丝做成环形角膜接触镜式电极,无关电极为记录脑电图用的银电极,贴于前额皮
The increase of children with myopia and chronic organophosphate pesticide poisoning reports have attracted people’s attention. Another record of chronic organophosphate poisoning ERG and found that a wave latency is prolonged. Therefore, in order to understand the relationship between myopia, organophosphorus pesticides and ERG, the authors recorded the ERG of 6-19-year-old myopic students and measured the a-wave peak time and the average of the fluctuating potentials (O_1, O_2, O_3 and O_4) And compared with ERG in children with eyesight. Full dilation before ERG recording, dark adaptation 15 minutes later. Stimulate the light source from the front of 30cm, the intensity of 20 Joules. The effective electrode is made of white gold wire contact lens cornea, irrelevant electrodes for recording EEG silver electrodes, affixed to the forehead skin
