Many papers have reported that motion perception asymmetry (MPA) is replaced by motion perception symmetry (MPS) by the 4th to 5th month after birth, when stereopsis starts to occur in normal infants. Duane's syndrome is a congenital motor abnormality, it does, however, reportedly show good stereopsis. We confirmed the stereopsis in Duane's syndrome and checked the motion perception (MP) by using the Reversing Grating Test to investigate if the congenital motor abnormality affects the MP in patients whose binocular sensory system is well developed. Thirty-eight Duane's syndrome patients aged 3 to 45 years were included in the present study. They were divided into 24 cases of Duane I, 9 cases of Duane II, 5 cases of Duane III. The Titmus Stereo Tests, Lang Stereotest, and TV-Random Dot Stereo Test were used to examine the stereopsis. Thirty-four patients had good stereopsis, and 4 had poor stereopsis. None of them showed MPA in any spatial frequencies (1/ 4, 1/2, 1 cycles/degree) examined. The Reversing Grating Test is useful for examining MPA in strabismus patients with eye movement limitations.
许多论文报道，出生后第4至5个月，当正常婴儿开始出现立体视觉时，运动感知不对称（MPA）会被运动感知对称（MPS）取代。杜安综合征是一种先天性运动异常，但据报道其立体视觉良好。我们确认了杜安综合征患者的立体视觉，并使用反转光栅测试检查了运动感知（MP），以研究这种先天性运动异常是否会影响双眼感觉系统发育良好的患者的MP。本研究纳入了38例年龄在3至45岁的杜安综合征患者。他们被分为杜安I型24例、杜安II型9例、杜安III型5例。使用Titmus立体视觉测试、Lang立体视觉测试和电视随机点立体视觉测试来检查立体视觉。34例患者立体视觉良好，4例患者立体视觉较差。在任何检查的空间频率（1/4、1/2、1周期/度）下，他们均未表现出MPA。反转光栅测试对于检查有眼球运动限制的斜视患者的MPA很有用。
