PURPOSE To explore the relationship between ocular position control ability and stereopsis recovery in children with intermittent exotropia, and to analyze the influencing factors of distance stereopsis recovery. METHODS In this retrospective study, 78 children with small angle intermittent exotropia received vision training for 3 months. All patients were examined for distance stereopsis with the synoptophore and for near stereopsis with the Titmus stereogram before and after the training. The patients were divided into low and high Newcastle Control Score (NCS) groups. The stereopsis of the two groups was compared. Logistic regression analysis was used to analyze the influencing factors of distance stereopsis recovery. RESULTS Among 78 children with intermittent exotropia, 33 had near stereopsis (42.3%) and 22 had distance stereopsis (28.2%); the difference was significant (P < .05). After 3 months of training, there were statistically significant differences between distance and near stereopsis in the low NCS group and the high NCS group (chi-square = 7.127, P = .008; chi-square = 13.005, P < .001). The number of children with distance and near stereopsis in the low NCS group increased significantly compared with before training (chi-square = 13.471, P < .001; chi-square = 22.244, P < .001). Multivariate logistic regression analysis showed that age of onset (odds ratio [OR] = 3.768, P = .001), near point of convergence (OR = 0.347, P = .002), and NCS (OR = 0.142, P = .002) were risk factors that affected stereopsis recovery in children with small angle intermittent exotropia. CONCLUSIONS Control ability is one of the important indicators to assess the severity of intermittent exotropia. The worse the control ability, the more difficult the recovery of stereopsis. Age of onset, near point of convergence, and NCS are risk factors that affect the recovery of distance stereopsis. [J Pediatr Ophthalmol Strabismus. 2021;58(6):350-354.].

控制能力对儿童间歇性外斜视立体视觉恢复的影响。

目的探讨间歇性外斜视患儿眼位控制能力与立体视觉恢复的关系，分析远距离立体视觉恢复的影响因素。方法 在这项回顾性研究中，78 名小角度间歇性外斜视儿童接受了 3 个月的视力训练。在训练前后，所有患者都用同视器检查了远立体视，并用 Titmus 立体图检查了近立体视。将患者分为低和高纽卡斯尔控制评分 (NCS) 组。比较两组的立体视觉。采用Logistic回归分析远距离立体视觉恢复的影响因素。结果 78例间歇性外斜视患儿中，近立体视33例（42.3%），远视立体视22例（28.2%）；差异显着（P < .05）。训练 3 个月后，低 NCS 组和高 NCS 组的远近立体视觉差异有统计学意义（卡方 = 7.127，P = .008；卡方 = 13.005，P < .001）。与训练前相比，低NCS组有远距离和近立体视觉的儿童数量显着增加（卡方= 13.471，P < .001；卡方= 22.244，P < .001）。多变量逻辑回归分析显示发病年龄（优势比 [OR] = 3.768，P = .001）、收敛点附近（OR = 0.347，P = .002）和 NCS（OR = 0.142，P = .002 ) 是影响小角度间歇性外斜儿童立体视觉恢复的危险因素。结论控制能力是评估间歇性外斜视严重程度的重要指标之一。控制能力越差，立体视觉的恢复就越困难。发病年龄、近点收敛点和 NCS 是影响远立体视恢复的危险因素。[J Pediatr Ophthalmol 斜视。2021;58(6):350-354.]。
