EOG, ERG and VEP reflect the function of different levels of the visual system. Therefore multiple testing (especially VEP and ERG) is necessary for reducing false positive and false negative and increasing the accuracy of prediction.

• EOG,ERG,VEP反映视系统不同平面的功能,故多项联测(尤其是VEP和ERG)对减少假阳性和假阴性,提高预测准确性是必要的。
