Abstract：
OBJECTIVE: The aim of this pilot study was to determine whether viewing an immersive 3D movie with large disparities in a cinema resulted in improved visual acuity (VA), stereoscopic depth perception (ST), and improved eye alignment in residual amblyopic children and children without amblyopia.
METHODS: A total of 24 children aged between 5 and 12 years with a history of anisometropic and/or strabismic amblyopia, that had been previously treated and who currently have residual amblyopia (N = 14), and in children with typical development without amblyopia (N = 10) viewed the movie in 3D Sing 2 in a cinema for 110 minutes. Visual acuity, stereoacuity and ocular deviation were assessed before viewing the movie, and three months later. Stereoacuity and ocular deviation were also measured immediately after viewing the movie.
RESULTS: We observed an improvement in visual acuity in the non-dominant (amblyopic) eye 3 months after viewing the movie in the amblyopic group (P<0.001). Stereopsis improved immediately after viewing the movie (P = 0.02), and after 3 months by ≈ 40% (P = 0.01). Moreover, improvements in stereopsis were also observed in children without amblyopia (P = 0.04). No significant changes in ocular deviation were observed in either group.
CONCLUSIONS: These pilot results suggest that brief exposure to large disparities by viewing a 3D movie in a cinema can help to improve stereopsis and visual acuity in children aged 5‒12 years with previously treated amblyopia, and provide a rationale for a randomized clinical trial.

摘要：
目的：这项初步研究的目的是确定在电影院中观看具有较大差异的沉浸式3D电影是否会提高视敏度（VA）。立体深度感知（ST），改善残余弱视儿童和无弱视儿童的眼睛对齐。
方法：共有24名年龄在5至12岁之间的儿童，有屈光参差和/或斜视性弱视史，以前接受过治疗，目前患有残余弱视（N=14），在没有弱视的典型发育的儿童（N=10）中，在电影院中观看了3DSing2电影110分钟。视敏度,在观看电影之前评估立体敏锐度和眼睛偏差，三个月后.还在观看电影后立即测量立体敏锐度和眼睛偏差。
结果：我们观察到弱视组在观看电影3个月后，非优势（弱视）眼的视力有所改善（P<0.001）。观看电影后，立体视觉立即改善（P=0.02），3个月后约40%(P=0.01)。此外，在无弱视的儿童中也观察到立体视觉的改善(P=0.04).两组均未观察到明显的眼偏变化。
结论：这些初步结果表明，通过在电影院观看3D电影来短暂暴露于较大的差异可以帮助改善5-12岁以前接受过弱视治疗的儿童的立体视觉和视力。并为随机临床试验提供了理论基础。
