Abstract

Our goal in this study was to determine the efficacy, time course and mechanisms underlying the improvement of stereo vision using 3D virtual reality (VR) games to improve depth perception in adults with a history of abnormal early visual experience due to strabismus, anisometropia and/or amblyopia. Participants engaged in 30 home-based training sessions, supplemented by 5 in-lab assessments to monitor progress. The training protocol utilized a diverse set of VR games targeting stereoacuity, anti-suppression, and binocular alignment. The stereo training games employed various depth cues to facilitate stereo vision recovery. Clinical, psychophysical and virtual reality tests were conducted to evaluate changes in stereoacuity, binocular balance, and interocular alignment. Results revealed significant improvements in stereoacuity for most participants following training, whereas outcomes for binocular balance and ocular alignment were more variable. Together, these findings suggest that VR-based training can reliably enhance stereoacuity in adults with abnormal visual histories, though individual variability highlights the need for personalized approaches and further investigation of underlying mechanisms.

双眼视力异常的成人深度知觉的恢复

在这项研究中，我们的目的是确定使用3D虚拟现实（VR）游戏改善立体视觉的功效、时间过程和机制，以改善因斜视、屈光参差和/或弱视而有早期视觉体验异常史的成年人的深度感知。参与者参加了30次以家庭为基础的培训课程，并辅以5次实验室评估来监测进展。训练方案利用了一套不同的VR游戏，目标是立体灵敏度、抗抑制和双目对准。立体视觉训练游戏采用不同深度线索促进立体视觉恢复。通过临床、心理物理和虚拟现实测试来评估立体视敏度、双目平衡和眼间对齐的变化。结果显示，大多数参与者在训练后的立体视敏度有显著改善，而双眼平衡和眼对准的结果则变化较大。总之，这些研究结果表明，基于vr的训练可以可靠地增强具有异常视觉史的成年人的立体视敏度，尽管个体差异突出了个性化方法和进一步研究潜在机制的必要性。

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.
