Abstract

To investigate the effect of high-order aberrations (HOAs) on pattern-reversal visual evoked potentials (PR-VEPs), we measured PR-VEPs with HOAs either retained or corrected with an adaptive optics (AO) system for 12 subjects. The PR-VEPs at different spatial frequencies were recorded for the dominant eye of each subject. The results indicated that the amplitude of the first positive P1 wave at 1-16 cpd (except 2 cpd) and the second negative N2 wave at 12 and 16 cpd were raised statistically significantly with HOA correction. This confirmed the contributions of the HOAs to the alterations in PR-VEPs, and suggested that HOAs should be corrected to realize accurate PR-VEP testing.

摘要

为研究高阶像差（HOAs）对图形翻转视觉诱发电位（PR-VEPs）的影响，我们对12名受试者使用自适应光学（AO）系统保留或校正HOAs的情况下测量了PR-VEPs。记录了每个受试者优势眼在不同空间频率下的PR-VEPs。结果表明，在1-16周/度（除2周/度外）时第一个正向P1波的幅值以及在12和16周/度时第二个负向N2波的幅值在HOA校正后有统计学显著升高。这证实了HOAs对PR-VEPs改变的影响，并表明应校正HOAs以实现准确的PR-VEP检测。
