我们对４６例正常人（８９眼）和３５例（５１眼）视神经病变病人记录其稳态闪光视诱发电位，其中５８．８％的患眼视力＜０．１。记录的波形通过离散傅里叶转换，提取基波和二次谐波的振幅和相位作为波形的特征值。结果表明，患眼总的异常率为８０．４％。异常改变可呈现４种类型：振幅降低，相位异常，振幅降低和相位异常，平坦波形。就稳态闪光视诱发电位对视神经病变诊断的意义及临床应用的优点进行了讨论。 We recorded steady-state flash visual evoked potentials in 46 normal subjects (89 eyes) and 35 (51 eyes) optic neuropathy patients, of whom 58.8% had visual acuity <0.1. The recorded waveforms extract the amplitudes and phases of the fundamental and second harmonics as the eigenvalues ​​of the waveforms by discrete Fourier transform. The results showed that the total abnormal rate of eyes was 80.4%. Abnormal changes can present four types: amplitude reduction, phase anomalies, amplitude reduction and phase anomalies, flat waveforms. The significance of steady-state flash visual evoked potentials in the diagnosis of optic neuropathy and the advantages of clinical application are discussed.
