方法：2011-05/2012-08在我院就诊的远视屈光不正性弱视儿童，按不同最佳矫正视力(best corrected vision acuity， BCVA)分为3组，P-VEP检查分析比较不同组间及与正常儿童的P₁₀₀波峰潜时和振幅的变化。

结果：正常组P₁₀₀波峰潜时101.43±6.82ms，P₁₀₀波振幅为11.27±5.38μV。在不同程度弱视组间P₁₀₀波峰较正常组潜时延迟，分别为视力高于0.5组110.54±8.47ms，视力0.3～0.5组118.76 ±6.21ms，视力低于0.3组124.54±7.36ms，且各组间差异有统计学意义(P<0.05)。P₁₀₀波振幅均较正常下降，分别为轻度组 9.94±5.28μV，中度组8.57±7.21μV，重度组7.49±5.07μV，各组间比较差异有统计学意义(P<0.05)。

结论：远视屈光不正弱视儿童的图形视觉诱发电位弱视眼的P₁₀₀波峰潜时延迟、P₁₀₀波振幅下降。且P₁₀₀波峰潜时延迟、P₁₀₀波振幅下降与弱视程度相关。

METHODS: We did P-VEP examination for the hyperopic refractive children from May 2011 to August 2012. We divided these children into three groups according to different best corrected vision(BCV): better than 0.5 amblyopic group, 0.3-0.5 amblyopic group and lower than 0.3 amblyopic group. Their P₁₀₀ latency and amplitude were measured and compared with normal children group.

RESULTS: The healthy eye's P₁₀₀ latency was 101.43±6.82ms, P₁₀₀ amplitude was 11.27±5.38μV. P₁₀₀ latency delay and P₁₀₀ amplitude decline in amblyopic group. Better than 0.5 amblyopic group, 110.54±8.47ms, 9.94±5.28μV; 0.3-0.5 amblyopic group 118.76±6.21ms, 8.57±7.21μV; and lower than 0.3 amblyopic group 124.54±7.36ms, 7.49±5.07μV. P₁₀₀ latency and amplitude have significant different between groups(P<0.05).

CONCLUSION: P₁₀₀ latency delay and P₁₀₀ amplitude decline in hyperopic refractive amblyopia and the changes are associated with degree of amblyopia.
