目的：介绍一种基于3D偏振检查系统的儿童双眼中心视野生理盲点检查方法及其研究机制。方法通过3D显示器和偏振光眼镜，受试者双眼进入完全分视状态，分别同时注视形状、大小、灰度相同的两个garbor斑，通过计算机程序描记中心视野的生理盲点范围，程序切换完成双眼检查。结果正常视力儿童27人（54眼），在检查视角固定情况下，其生理盲点范围位于中心注视点两侧，水平498.17±47.09像素至736.33±39.02像素之间，垂直方向上方52.08±29.89像素至下方213.42±41.14像素之间；生理盲点横径为238.17±26.57像素，垂直径为266.33±49.86像素。高度近视存在视盘萎缩弧时，生理盲点呈现月牙形改变。结论3D偏振光检测系统测量时间短且结果可量化，是一种适于儿童检查的新方法。

Objective To introduce a new type of inspection method for physiological blind spot in binocular vision field.Methods The binocular vision separation was performed using polarized glasses and three-dimensional video technology. Binocular suppression was detected using two different sized targets. The testing eye gazed one garbor spot,The other garbor spot was controlled by mouse operation, moving from the center to the edge of the display. Program recorded the No. 2 garbor spot as the standard vanishing point, tracing the blind spot range in central visual field.Results The examination included 27 normal children (54 eyes). Under the condition of fixed inspection angle, the scope of its physiological blind spot was located at both sides of central fixation point. In horizontal direction, it located from 498.17±47.09 pixels to 736.33±39.02 pixels. In vertical direction, it was from above 52.08 ± 29.89 pixels to below 213.42± 41.14 pixels. Horizontal diameter of physiological blind spot was 238.17 ±26.57 pixel, the vertical diameter was 266.33± 49.86 pixels. Conclusions 3D polarized binocular vision in-spection system is a novel method for measuring physiological blind spot for children.
