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.
