BACKGROUND
The purpose of this study was to determine if vision training with the EYEPORT system affects vision and reading performance. (Subsequent to this study, the "E.Y.E." has been renamed "EYEPORT")
METHODS
College students with normal vision (n = 31) participated in a blind, crossover study to assess within-subject and between-group effects of EYEPORT training. Half the subjects initially underwent training (10 minutes per day, 6 days a week for 3 weeks), and then crossed over to the no-train control condition (3 weeks); the other half underwent the reverse sequence. Vision and reading performance were assessed at baseline, 3 weeks, and 6 weeks.
RESULTS
Multivariate analyses (Hotelling's T2) found small improvements in vergence and accommodative facility, reading performance, and stereopsis response time after EYEPORT training (P < 0.025). Enhancements in reading performance and vergence facility were still present 3 weeks after cessation of training (P < 0.001).
CONCLUSIONS
The EYEPORT training system shows potential to enhance visual performance and reading ability. Studies are underway to assess its efficacy in symptomatic populations.
背景
本研究旨在确定使用EYEPORT系统进行视力训练是否会影响视力和阅读表现。（在本研究之后，“E.Y.E.”已更名为“EYEPORT”）
方法
视力正常的大学生（n = 31）参与了一项盲法交叉研究，以评估EYEPORT训练在个体内和组间的效果。一半受试者最初接受训练（每天10分钟，每周6天，共3周），然后交叉至无训练的对照状态（3周）；另一半则接受相反的顺序。在基线、3周和6周时评估视力和阅读表现。
结果
多变量分析（Hotelling's T2）发现，EYEPORT训练后，在集合和调节功能、阅读表现以及立体视反应时间方面有小幅改善（P < 0.025）。训练停止3周后，阅读表现和集合功能仍有提高（P < 0.001）。
结论
EYEPORT训练系统显示出增强视觉表现和阅读能力的潜力。正在进行研究以评估其在有症状人群中的疗效。
