Childhood albinism. Visual electrophysiological features.

Flash ERGs and VEPs, and VEPs to pattern onset and pattern reversal stimulation were recorded in young albino children and compared to age-matched, normally pigmented, controls. In albinos, the ERG had a significantly larger a-wave, and significantly shorter latencies for both the a-wave and b-wave. VEPs to flash, pattern onset and pattern reversal stimulation all showed an occipital crossed asymmetry when comparing responses from each eye. However, the findings for flash stimulation were more consistent and reliable than those to either form of pattern stimulation.
