本文用多焦视诱发电位研究屈光不正性弱视眼在视野不同离心度的视功能变化。刺激图形由６１个小六边形组成。刺激野直径约１３．６度。在电脑程序控制下，各六边形同时并互相独立地进行刺激，自动分离提取到各自的反应波形。屈光不正性弱视眼与正常对照眼比较，在刺激图形中心区潜伏期延长，振幅下降，差异有显著性。本研究证实，屈光不正性弱视眼视野中心区视功能下降比周边区显著
In this paper, multifocal visual evoked potentials of refractive amblyopia eyes visual field of different visual function changes. The stimulus graphic consists of 61 small hexagons. Stimulation field diameter of about 13.6 degrees. Under the control of a computer program, the hexagons simultaneously and independently stimulate each other, and automatically extract and extract their respective reaction waveforms. Refractive amblyopia eyes compared with the normal control eyes, stimulation of the central area of the figure latency, amplitude decreased, the difference was significant. This study confirmed that visual acuity decreased in the central area of refractive amblyopia than in peripheral areas significantly
