摘　　要：目的观察间歇性外斜视患者的眼位控制力及双眼视觉功能状况，寻找合适的眼位控制力检查方法及评分标准。方法收集2011年10月至2012年10月在保定市第二中心医院眼科门诊就诊的遮盖试验阳性患者分别检查眼位控制力及双眼视觉。眼位控制力参照Mayo评分标准，观察患者的远距离眼位控制力。根据用时不同计为0～5分。0分为外隐斜，5分为可疑恒定性外斜视，均予以排除。1-4分患者共40例，其中男性18例，女性22例，年龄7～15岁，平均（10．4±2．72）岁。依据控制力评分分为两组：1-2分为第一组，3-4分为第二组，每组各20例，比较两组患者的双眼视觉功能状况。双眼视觉应用Titmus《立体视觉检查图》检查近立体视，应用长春光电生产的同视机检查同时视、融合范围，随机点图片检查定量远立体视。结果第一组患者的同时视重合点位置、融合范围、远立体视锐度及近立体视锐度四项观察指标均优于第二组患者，差异具有统计学意义（P〈0．05）。结论不同控制力的间歇性外斜视患者双眼视觉功能具有差异，远距离眼位控制力检查方便，结果可靠。该评分可以作为评价间歇性外斜视患者病情轻重的指标之一。Objective To observe the eye position control and functional status of binocular vi- sion in intermittent exotropia patients, to find the suitable eye position control check methods and scoring criteria for oblique amblyopia. Methods Intermittent exotropia patients were collected from our department during October 2011 to October 2012, and the eye position control and visual func- tion was checked. In order to observe the eye position control, the marking methods of Mayo was used. The specific methods as follow： Patients stared at the 6 meters object, for masking experi- ment, and the time needed for eye restore was observed, according to the time different, assigned 0-5 points respectively. 0 point： exophoria, 5 point： Suspicious constancy exotropia. The patients dur- ing 1-4 point were 40 cases, including 18 males and 22 females, aged 7-15 years, mean 10.44-2.72 years old, and everyone were examined binocular vision. The process as follow： Application Titmus check figure in stereo vision inspection near stereopsis, Application with the machine to check at the same time, convergence range and far stereopsis. All 40 patients were divided into two groups： control over the score 1-2 fall into the first group, 3-4 into the second group, and comparison the binocular vision function of two groups of patients. Results The patients＇ simultaneous vision coincidence point location, the range of fusion, near and far stereo visual sharpness and stereoscopic sharpness of the first group were better than the second group of patients. There was significant dif- ference in statistics （P 〈0.05）. Conclusions Binocular vision fimction of intermittent exotropia pa- tients who have different control force, and through checking the eye position control judgment state of intermittent exotropia patients.
