To explore the effect of applying binocular visual training after slanted lateral rectus recession on orthophoric rate and binocular visual function recovery on patients with convergence insufficiency-type intermittent exotropia (CI-IXT).
A total of 76 CI-IXT child patients treated at the Strabismus and Pediatric Ophthalmology Department of our hospital from June 2019 to June 2020 were selected as the research objects, and those who met the inclusion criteria were equally divided into group A (63 eyes) and group B (61 eyes) according to the sealed envelope randomization. All child patients accepted the slanted lateral rectus recession, and after that, those in group A accepted the binocular visual training and those in group B accepted the conventional visual function rehabilitation training, so as to compare their position of eye, the best corrected visual acuity, etc., after training for statistical analysis.
Compared with group B after one month of surgery, group A had significantly less patients with grade I binocular vision function ( < 0.001) and more patients with grade II and III vision function ( < 0.05); between group A and group B, after 3 months and 6 months of treatment, the number of eyes with normal stereoscopic vision was significantly higher in group A ( < 0.05); at 15 days, 1 month, 3 months, and 6 months of treatment, the visual strain scores of group A were significantly lower ( < 0.001); after treatment, the number of orthophoria eyes was significantly higher in group A ( < 0.001), while the numbers of overcorrected eyes and undercorrected eyes were significantly higher in group B ( < 0.001); and the total incidence rate of adverse reactions was significantly lower in group A ( < 0.05).
Applying binocular visual training to child patients with CI-IXT after slanted lateral rectus recession can promote the recovery of binocular vision and ensure higher safety, and further study will help to establish a better solution for the affected children.
探讨对集合不足型间歇性外斜视（CI-IXT）患者行斜肌后徙术后应用双眼视觉训练对正位率及双眼视觉功能恢复的影响。
选取2019年6月至2020年6月在我院斜视与小儿眼科接受治疗的76例CI-IXT患儿作为研究对象，将符合纳入标准的患儿按密封信封随机法等分为A组（63眼）和B组（61眼）。所有患儿均接受斜肌后徙术，术后A组接受双眼视觉训练，B组接受传统视觉功能康复训练，比较两组训练后的眼位、最佳矫正视力等情况并进行统计学分析。
术后1个月，与B组相比，A组双眼视觉功能Ⅰ级患者明显减少（<0.001），Ⅱ级和Ⅲ级视觉功能患者增多（<0.05）；治疗3个月和6个月时，A组立体视觉正常眼数明显多于B组（<0.05）；治疗15天、1个月、3个月和6个月时，A组视觉疲劳评分明显更低（<0.001）；治疗后，A组正位眼数明显多于B组（<0.001），而B组过矫眼数和欠矫眼数明显多于A组（<0.001）；A组不良反应总发生率明显更低（<0.05）。
对CI-IXT患儿行斜肌后徙术后应用双眼视觉训练可促进双眼视觉恢复并确保更高安全性，进一步研究将有助于为患病儿童建立更好的解决方案。
