摘　　要：目的：评估健康婴儿的视觉诱发电位（VEP）。方法：选取34例神经系统及眼部均健康的、年龄为2-10月龄的婴儿,运用闪光VEP检查并比较双眼P3波潜伏期与振幅。结果：所有婴儿的P3波数据均被记录。其平均潜伏期为138-140ms,振幅为7-9μV。潜伏期不稳定。结论：病理状态下,婴儿的潜伏期或振幅可能不会出现变异。而由于视路和皮层的髓鞘发育会使其出现变异,应注意类似于P3波的皮层波或其他波出现。因此,使用闪光VEP检测年龄为1-3月龄的婴儿是不准确的。AIM： To evaluate visual evoked potentials （VEPs） in healthy infants. METHODS： Thirty - four neurologically and ophthalmologically healthy infants aged 2- 10 mo were enrolled. Flash VEPs were implemented, with main peak P3 latency, amplitude and differences of latency and amplitude between sides being investigated. RESULTS： In all cases main peak was registered. Its average latency was 138-140 ms and main amplitude 7-9 μV. Latency was variable. CONCLUSION： We propose that latency or amplitude deviation in this population may not happen due to pathological condition, but merely due to ongoing myelination of visual pathways and cortex modeling. Caution needed in attributing the main cortical peak as P3 or some other waves numbers. Cortical nature of the main flash visual evoked potentials peak in infants aged 1-3mo is doubtful.
