The use of digital devices provides a wide range of possibilities for measuring and improving visual function, including concepts such as perceptual learning and dichoptic therapy. Different technologies can be used to apply these concepts, including, in recent years, the introduction of virtual reality (VR) systems. A preliminary experience in treating anisometropic amblyopia through an immersive VR device and using prototype software is described. A total of 4 children were treated by performing 18 office-based sessions. Results showed that distance VA in amblyopic eyes remained constant in two subjects, whereas the younger subjects improved after the training. Near VA improved in three subjects. All subjects showed an increase in the stereopsis of at least one step, with three subjects showing a final stereopsis of a 60 s arc. A total of three subjects showed an increase of approximately 0.5 CS units for the spatial frequency of 3 cpd after the training. Results from this pilot study suggest that visual training based on perceptual learning through an immersive VR environment could be a viable treatment for improving CS, VA, and stereopsis in some children with anisometropic amblyopia. Future studies should support these preliminary results.
数字设备的使用为测量和改善视觉功能提供了广泛的可能性，包括感知学习和双眼分视疗法等概念。可以使用不同的技术来应用这些概念，近年来，虚拟现实（VR）系统的引入就是其中之一。本文描述了通过沉浸式VR设备和使用原型软件治疗屈光参差性弱视的初步经验。共有4名儿童接受了18次门诊治疗。结果显示，两名受试者弱视眼的远视力保持不变，而年龄较小的受试者在训练后视力有所改善。三名受试者的近视力有所提高。所有受试者的立体视至少提高了一个等级，三名受试者最终的立体视达到了60秒弧度。共有三名受试者在训练后，对于3 cpd的空间频率，对比敏感度增加了约0.5个对比敏感度单位。这项初步研究的结果表明，通过沉浸式VR环境进行基于感知学习的视觉训练可能是改善一些屈光参差性弱视儿童对比敏感度、视力和立体视的一种可行治疗方法。未来的研究应支持这些初步结果。
