研究表明多焦视诱发电位可反映对应于视野各部位的客观视功能 ,然而 ,电极位置的改变对多焦视诱发电位的波形影响很大。本研究探索单极记录与双极记录的多焦视诱发电位的波形差异 ,以便为临床使用多焦视诱发电位提供依据。对象与方法1.对象 :正常对照眼 30例 30眼 ,其中男 18例 Studies have shown that multifocal evoked potentials can reflect the objective visual function corresponding to various parts of the visual field, however, the electrode position changes have a great influence on the multifocal visual evoked potential waveform. This study explores the differences between the multifocal evoked potentials of unipolar and bipolar recordings in order to provide a basis for the clinical use of multifocal evoked potentials. Subjects and methods 1. Subjects: 30 cases of normal control 30 eyes, of whom 18 were male
