收集了１１０ 例弱视儿童模式视觉诱发电位资料，经分组研究和统计学分析，结果表明：①弱视儿童Ｐ波潜伏期ＬＰ１００与正常人比较差异有显著性（Ｐ＜ ０．０５）；②弱视儿童按弱视程度分轻、中、重三组，自身比较，Ｐ波潜伏期和振幅各组间差异无显著性（Ｐ＞ ０．０５）。
The data of visual evoked potentials of 110 children with amblyopia were collected and analyzed by grouping and statistical analysis. The results showed that: (1) The latent period of P wave in amblyopia children was significantly lower than that in normal subjects (P <0.05); The degree of amblyopia in mild, moderate and severe three groups, their own comparison, P wave latency and amplitude differences between the groups was not significant (P> 0.05).
