摘　　要：目的:分析分离性垂直偏斜(DVD)合并间歇性外斜视患者的临床特征,探讨间歇性外斜视患者的发病年龄及双眼视功能水平与DVD的关系。方法:回顾性分析177例患者的临床资料,将其分为组1:DVD合并间歇性外斜视;组2:单纯间歇性外斜视;组3:单纯DVD。比较并分析3组病人的发病时间、术前立体视功能及垂直分离偏斜程度。结果:DVD合并间歇性外斜视患者的发病月龄(45.0月)早于单纯间歇性外斜视(82.9月)(P<0.01)。其双眼视功能较单纯间歇性外斜视组差(P<0.01)。组1与组3的垂直分离斜度分别为14.5△±9.6△、23.7△±15.4△,差异有统计学意义(P<0.05)。结论:DVD合并间歇性外斜视发病年龄较早,双眼视功能较差。视觉发育早期双眼视功能的破坏可能是影响DVD发生发展的重要因素。DVD合并间歇性外斜视中的水平方向眼位偏斜对垂直斜视度有一定影响。Objective： To describe the characteristics of dissociated vertical deviation （DVD） in patients with intermittent exotropia and determine whether the age of strabismus onset and the degree of stereopsis are related to the development of DVD in patients with intermittent exotropia and DVD. Methods： 177 patients were retrospectively recorded and divided into three groups： （1） intermittent exotropia with DVD; （2） intermittent exotropia without DVD and （3） simple DVD. Age of strabismus onset, binocular vision function, and vertical deviation measurements were analyzed. Results： 39 patients with intermittent exotropia and DVD were identified. In intermittent exotropia with DVD and intermittent exotropia without DVD group, the mean age of strabismus onset was 45.0 months and 82.9 months, respectively （P〈0.01）. Group 1 showed worse binocular visual function than group 2 （P〈0.01）. The measurements of vertical devia- tion in group 1 and 3 were 14.5△±9.6△ and 23.7△±15.4△, respectively （P〈0.05）. Conclusion： Intermittent exotropia with DVD is characterized by earlier onset of strabismus and worse stereopsis, which suggest that poor binocular visual function in early period of life may be related to the development of DVD. Horizontal deviation in DVD patients with intermittent exotropia may have effect on the size of vertical deviation.
