N₇₀–P₁₀₀ and P₁₀₀-N₁₄₅ amplitudes of P-VEP.

<p>(A) The N₇₀–P₁₀₀ amplitudes significantly decreased after optic nerve semi-transection compared with the control eyes at the same time point (P_3d<0.05, P_1w<0.01, P_2w<0.001, P_4w<0.001, P_8w<0.001, n = 6/group). (B) The P₁₀₀-N₁₄₅ amplitudes significantly decreased after the optic nerve injury compared with the control groups at the same time point (P_3d<0.05, P_1w<0.01, P_2w<0.001, P_4w<0.001, P_8w<0.001, n = 6/group), the amplitudes tendency of both (A) and (B) decreased gradually as time prolonged in the experimental groups individually. Both (A) and (B) amplitudes have no significant difference at different time points among the control groups. (P>0.05, n = 6/group). Error bars indicate SD.
