Abstract

Before VEP use in clinics, we studied in statistical significance between borh eyes, intrasubject varciabilty intersubject variability (between incdividul) and changes of VEP cmponents between ignorance and attention in losujects (20eyes). There was no statistically significant difference between both eyes in each component of VEP and the variability of intersubjects was larger than that of intrasubjects. The smallest variability of intersubject was N1, P1 latency and that of intrasubject was PI latency in each component of VEP. When subjects were ignored, N1-P1, P1-N2 and steady VEP amplitude decreased significantly but N1, P1 and N2 latency were no significant difference.
