Pattern visual evoked potentials (VEPs) and behavioral visual acuity measured with forced-choice preferential looking techniques (FPL) were obtained from 172 pediatric patients between the ages of 4 months and 10 years. More children younger than 2 years of age successfully completed monocular testing by pattern VEP than by FPL methods. For children older than 2 years, we were equally successful in completing each of the two tests. Of those children who completed both tests, the VEP results agreed with Snellen, Allen, and "E" acuity measures more often (66%) than did the FPL results (50%). Both tests were more sensitive than Allen single characters in detecting interocular acuity differences in children younger than 3 years of age.
对172名年龄在4个月至10岁之间的儿科患者进行了图形视觉诱发电位（VEP）检查，并采用强迫选择优先注视技术（FPL）测量了行为视力。与FPL方法相比，更多2岁以下的儿童通过图形VEP成功完成了单眼测试。对于2岁以上的儿童，我们在完成这两项测试中的任何一项时都同样成功。在完成两项测试的儿童中，VEP结果与斯内伦、艾伦和“E”视力测量结果的一致性更高（66%），高于FPL结果（50%）。在检测3岁以下儿童的两眼视力差异方面，这两项测试都比艾伦单字符测试更敏感。
