The effect of three-dimensional video technology test in physiological blind spot in children
摘要
Abstract
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.关键词
