Abstract

Recent advancements in the treatment of amblyopia have adapted visual media (video games and movies) into dichoptic tasks to promote binocular function. This study demonstrates the feasibility of a treatment based on another important daily task: reading. We propose that dichoptic e-book applications may serve as an alternative treatment for binocular vision in amblyopia.

We developed a prototype of a dichoptic e-book reading application (D.E.B.R.A), that was installed on Android tablets used for participant assessments. Participants read e-books in anaglyph red/green/black presentation, which allowed for monocular and binocular contrast to be adjusted independently. Amblyopic and control participants were then tested on their reading speed and questioned about their comfort using the application.

We found that participants were able to read in the dichoptic presentation, albeit slower than when the books were presented in the typical “binocular” form. This suggests that the visual system can integrate information from both eyes to support reading. For some amblyopic participants, reducing the contrast of text seen by the fellow eye increased their reading speed in accordance with current research on balancing the contrast of the two eyes to unlock binocularity. At the end of each session, participants provided feedback on their comfort using the application.

Overall, this study demonstrated that amblyopes can read with both eyes when text is presented in a dichoptic format. Thus, our findings suggests that the dichoptic e-book reading application could provide an effective framework for an amblyopia treatment protocol.

一种改善弱视视力的新型双视阅读工具的研制。

弱视治疗的最新进展是将视觉媒体（视频游戏和电影）融入到双视任务中，以促进双眼功能。这项研究证明了一种基于另一项重要日常任务——阅读——的治疗方法的可行性。我们建议，二分电子书应用程序可能作为一种替代治疗双眼视力弱视。我们开发了一个二分法电子书阅读应用程序（D.E.B.R.A）的原型，安装在用于参与者评估的Android平板电脑上。参与者阅读红/绿/黑三种颜色的电子书，这样可以独立调整单眼和双眼的对比度。然后测试弱视和对照组参与者的阅读速度，并询问他们使用该应用程序的舒适度。我们发现，参与者能够以双视形式阅读，尽管比以典型的“双眼”形式阅读慢。这表明视觉系统可以整合来自两只眼睛的信息来支持阅读。对于一些弱视参与者来说，降低另一只眼睛看到的文本对比度可以提高他们的阅读速度，这与目前关于平衡两只眼睛对比度以解锁双眼的研究一致。在每个疗程结束时，参与者就他们使用应用程序的舒适度提供反馈。总的来说，这项研究表明，当文本以两视格式呈现时，弱视者可以用两只眼睛阅读。因此，我们的研究结果表明，双视电子书阅读应用程序可以为弱视治疗方案提供有效的框架。

期刊介绍： Vision Research is a journal devoted to the functional aspects of human, vertebrate and invertebrate vision and publishes experimental and observational studies, reviews, and theoretical and computational analyses. Vision Research also publishes clinical studies relevant to normal visual function and basic research relevant to visual dysfunction or its clinical investigation. Functional aspects of vision is interpreted broadly, ranging from molecular and cellular function to perception and behavior. Detailed descriptions are encouraged but enough introductory background should be included for non-specialists. Theoretical and computational papers should give a sense of order to the facts or point to new verifiable observations. Papers dealing with questions in the history of vision science should stress the development of ideas in the field.
