Introduction: Visual evoked potentials (VEPs) are potential differences recorded on the scalp in response to visual stimulation. They are obtained with slowly repeated stimuli. The aim of this study was to determine the normative values of the visual evoked potentials in our setting.
Methodology: We conducted a cross-sectional study from February 1 to April 30, 2019 at the Clinical Neurophysiology laboratory of the I.P. Ndiaye Clinic at CHNU Fann in Dakar (Senegal).
Results: We found that men had high averages of N75, P100 and N145 wave latencies and low averages of P100 wave amplitude (p>0.05). However, neither age nor body mass index influenced the parameters of VEPs.
Conclusion: Sex is important physiological variable in establishing laboratory normative values for VEPs. There is a marked difference between the sexes for the VEPs parameters.
