METHODS: A total of 64 patients who had undergone an operation for intermittent exotropia were recruited and divided into the training group and the control group based on whether they would receive the dichoptic training. The dichoptic training was conducted for 3 months in the training group and the control group would not accept any form of orthoptic therapy. Assessments of binocular visual functions and deviation were conducted at baseline, 3-month and 6-month follow-up.
RESULTS: Twenty-nine participants in the training group (mean 9.69 ± 2.66 years old) and 26 participants in the control group (mean 8.41 ± 2.64 years old) completed follow-up. At both 3- and 6-month follow-ups, the training group showed superior distance stereopsis compared to the control group, with near stereopsis only showing significant difference at the 6-month follow-up. Additionally, the training group exhibited significantly less distance exo-deviation drift than the control group at these times, and no significant difference was observed in near exo-deviation drift between the groups. The control group had a significantly higher rate of suboptimal surgical outcomes at both the 3- and 6-month follow-up. However, no significant differences were observed in simultaneous perception and fusion functions between the two groups.
CONCLUSIONS: Online video game-based dichoptic training has the potential to become a novel postoperative rehabilitation strategy for patients with intermittent exotropia.
方法:选择64例间歇性外斜视手术患者,根据是否接受双联训练分为训练组和对照组。训练组进行3个月的双视训练,对照组不接受任何形式的矫正治疗。在基线时进行双眼视觉功能和偏差的评估,3个月和6个月随访。
结果:训练组29名参与者(平均9.69±2.66岁)和对照组26名参与者(平均8.41±2.64岁)完成随访。在3个月和6个月的随访中,与对照组相比,训练组显示出更好的距离立体视觉,近立体视在6个月的随访中仅显示出显着差异。此外,在这些时间,训练组的距离外偏差漂移明显少于对照组,两组间近外向漂移无显著差异。在3个月和6个月的随访中,对照组的手术结局次优率明显更高。然而,两组的同时感知和融合功能无显著差异.
结论:基于在线视频游戏的双床训练有可能成为间歇性外斜视患者的一种新的术后康复策略。
