Abstract

The purpose of the study was to analyze chromatic visual evoked potential (VEP) responses to isoluminant red–green (R–G) and blue–yellow (B–Y) stimuli in 30 preschool children (1.5–6  years). The predominant part of the response consisted of a positive (P) wave, which showed age-related latency changes (linear decrease). P wave latency was shorter when using 21° compared to 7° R–G (p=0.004) and B–Y (p=0.044) stimulus and also when using 21° R–G compared to 21° B–Y stimulus (P=0.000). P wave amplitude did not show age-related changes. However, a lower amplitude was recorded when using 7° R–G stimulus (p=0.0013) and also when using B–Y compared to R–G stimulus. We may conclude that chromatic VEP to R–G and B–Y stimuli is reliably recorded in preschool children and that P wave to R–G stimulation shows a higher amplitude and shorter latency than to B–Y stimulus.
