[Automatic discriminatory analysis of visually evoked potentials waveforms in normals and amblyopes].
We presented a method of discriminatory analysis for the discrimination of P-VEP waveforms in frequency domain, and used this analysis in the discrimination of the P-VEP waveforms of normal eyes and amblyopic eyes. In this analysis, the amplitudes and the phases of the first to the sixth harmonics of P-VEP waveforms were calculated, thus 12 parameters of the P-VEP waveform were obtained for the discriminatory analysis. The P-VEP waveforms of thirty-one normal eyes and thirty-one amblyopic eyes were used to establish the discriminatory system. The result of clinical application showed that this method of Discriminatory Analysis was effective for the discrimination between normal and amblyopic P-VEP.
