Background The multifocal visual evoked potential (mfVEP) is a useful tool for evaluating optic nerve disease and visual defects secondary to optic nerve or retinal ganglion cell damage. Objective The aim of this study was to establish technical guidelines and normative values of the peak time and amplitude of the mfVEP in adolescents. Participants and methods This is a prospective study conducted on 20 healthy adolescents (40 eyes) 10 girls and 10 boys. Their age ranged between 10 and 15 years with a mean of 12.50 ΁ 1.48. Monocular mfVEP was obtained from each eye separately. The peak time and amplitude of the P1 wave of each individual response were measured and then expressed in the form of four quadrants. Results The peak time and amplitude of the P1 wave showed no statistical differences between the four quadrants and no correlation to the age. There were no statistically significant differences between girls and boys or between left and right eyes regarding the peak time and the amplitude of the P1 wave. Conclusion We obtained normative data of mfVEP of the adolescents in our lab as a preliminary work for further application in different neuro-ophthalmological disorders.
