记录１４对弱视双生子儿童的视觉诱发电位，其中单卵双生子８对，双卵双生子６对，共有弱视患者２１人，正常视力者７人，探讨了双眼和单眼刺激时视觉诱发电位的遗传特性。结果表明，这些受试儿童左右眼间ＶＥＰ波的主要分析参数差异无显著性，而双眼刺激时的ＬＰ１、ＡＰ１、及ＮＰ１对内方差有极显著性差异（Ｐ＜０．０１），这些参数的遗传度也较大。因而，我们认为视觉诱发电位具有遗传特征，双眼刺激ＶＥＰ波形的Ｐ１００波潜伏期及其振幅可作为弱视双生子儿童卵别鉴定的参考指标，同时表明弱视的发生可能与遗传有关。
The visual evoked potentials of 14 children with amblyopia were recorded. Among them, 8 pairs of monozygotic twins and 6 pairs of twins had 21 eyes with amblyopia and 7 eyes with normal vision. The visual evoked potentials Genetic characteristics. The results showed that there was no significant difference in the main analysis parameters of left and right VEP waves in these children, while there was a significant difference (P <0.01) between the inner variance of LP1, AP1 and NP1 in both eyes when stimulated by both eyes. These parameters Heritability is also greater. Therefore, we believe that the visual evoked potential with genetic characteristics, eyes stimulated VEP waveform P100 wave latency and its amplitude can be used as amblyopic asparental children do not identify the reference index of eggs, also shows that the occurrence of amblyopia may be related to genetic.
