意义目前，弱视的治疗是遮挡或惩罚较强的对侧眼。不到 30% 的患者使用这些治疗可以改善立体视觉。为了改善这些结果，该小组提出了一种治疗方法，通过在家中使用的游戏形式的感知学习来刺激立体视觉。目的本研究的目的是确定计算机视频游戏形式的随机点刺激 (RDS) 知觉学习是否能改善有弱视病史的患者的立体视觉。方法 32 名先前接受弱视治疗的立体缺陷患者（7 至 14 岁）参与了一项前瞻性、随机、双盲研究。参与者在家中使用 RDS 软件进行感知学习计划。在实验组中，立体视觉的需求增加，直到达到最低的可检测视差。在对照组中，刺激间隔是一个常数（840 到 750"）。使用 Randot 学龄前立体视觉测试 (RPST) 和 Wirt Circles 评估立体视觉。结果中位顺应性为 100%（四分位距 [IQR] = 78.50 到100). Log10 立体视觉结果在组间有显着差异 (RPST, P = .041; Wirt Circles Test, P = .009). RPST 的立体视觉改善中位数为 50% (IQR = 0.00 to 75%) 和 0% (IQR) = 0.00 至 7.5%），分别为实验组和对照组（P = .008）。Wirt Circles 改善分别为 46.42%（IQR = 6.25 至 73.75%）和 0%（IQR = 0.00 至 57.50%），分别为实验组和对照组 (P = .089)。当成功被认为是 RPST 增加 70% 时，组间立体视力改善没有差异（P = .113）；当成功被认为是 Wirt 圆两个级别的增益和 140" 或更低的立体视 (P = .023) 时，它在统计学上是不同的。使用 RPST 测量时，立体视在 6 个月后保持稳定，而使用 Wirt 测量时，两名受试者的立体视恶化圆圈结论在游戏环境中使用 RDS 在家中直接刺激立体视觉可以改善有弱视史的立体缺陷受试者的立体视觉。

A Random Dot Computer Video Game Improves Stereopsis

SIGNIFICANCE Currently, treatments for amblyopia are occlusion or penalization of the stronger fellow eye. Fewer than 30% of patients improve stereoacuity using these treatments. In order to improve these outcomes, this group proposes a treatment to stimulate the stereoacuity through perceptual learning in a game format for use at home. PURPOSE The aim of this study was to determine whether perceptual learning with random dot stimuli (RDS) in the form of a computer video game improves stereopsis in patients with a history of amblyopia. METHODS Thirty-two stereo-deficient patients (7 to 14 years old) previously treated for amblyopia participated in a prospective, randomized, double-blind study. Participants followed a perceptual learning program at home using RDS software. In the experimental group, the demand of stereopsis was increased, until reaching the lowest detectable disparity. In the comparison group, the stimulation interval was a constant (840 to 750"). Stereoacuity was evaluated with the Randot Preschool Stereoacuity Test (RPST) and the Wirt Circles. RESULTS Median compliance was 100% (interquartile range [IQR] = 78.50 to 100). Log10 stereoacuity outcomes were significantly different between groups (RPST, P = .041; Wirt Circles Test, P = .009). Median stereoacuity improvement with RPST was 50% (IQR = 0.00 to 75%) and 0% (IQR = 0.00 to 7.5%), respectively, for experimental and comparison groups (P = .008). Wirt Circles improvement was 46.42% (IQR = 6.25 to 73.75%) and 0% (IQR = 0.00 to 57.50%), respectively, for experimental and comparison groups (P = .089). Stereoacuity improvement was not different between groups when success was considered a 70% gain in RPST (P = .113); it was statistically different when success was considered a gain of two levels on Wirt Circles and stereoacuity 140" or less (P = .023). Stereoacuity remained stable after 6 months when measured with RPST, whereas it worsened in two subjects when measured with Wirt Circles. CONCLUSIONS Direct stimulation of stereopsis at home using RDS in a game environment improves the stereoacuity in stereo-deficient subjects with a history of amblyopia.
