| Abstract: | P VEP were recorded with MVT III instrument under monocular and bionocular viewing conditions in 100 children with normal visual acuity and aged from 4 to 8. The standard values of latencies of N1, P1, N2 and the amplitude of N1 P1 were from those children. The latencies decreased while the amplitude increased as spatial frequency increased. No statistically significant difference was found in the latencies and amplitudes between the left and right eyes, but the amplitudes of females were slightly higher than those of males, and the latencies of females are shorter than those of males. Topography of P VEP shows symmetry in distribution of isopotential lines. |
