)--Linking the Frontier of Technology, Serving Business InnovationRecently, Leap Motion shared a case study in which the medical technology company Vivid Vision utilized VR and the Leap Motion hand-tracking module to treat amblyopia. Previously, Qingting Network had reported on Vivid Vision’s use of eye-tracking technology to stimulate binocular vision in both retinas via VR, thereby alleviating patients’ visual impairments.
Currently, Vivid Vision’s solutions have been implemented in over 300 ophthalmology hospitals worldwide. In two independent studies, the solutions received positive feedback, with researchers concluding that this medical technology will ultimately benefit millions of people globally.
Vivid Vision CEO James Blaha stated that Vivid Vision utilizes VR games in clinical settings to treat patients. These games incorporate gesture-based actions, such as grasping, to exercise patients’ eye-hand coordination skills, while enabling real-time monitoring of their performance. A key feature of the Vivid Vision VR therapy is its ability to calibrate binocular visual function by presenting different images to each eye, thereby gradually reducing the disparity in visual acuity between the two eyes.
Another feature of the Vivid Vision treatment protocol is that it is more engaging than traditional behavioral therapy. It offers six different games, including a space shooter with multiple difficulty levels, suitable for all age groups. Patients must maintain binocular coordination to succeed, thereby effectively strengthening the weaker eye. Meanwhile, patient performance in the games is monitored in real time, allowing physicians to better assess treatment efficacy.
It is reported that there are approximately 135 million people with amblyopia worldwide, and Blaha is one of them. Specifically, he suffers from strabismus. Because his eye fixation point differs from that of the general population, his brain began to ignore the visual input from his non-dominant eye, leading to progressively worsening vision and a loss of depth perception. For this condition, early treatment is typically critical, as traditional therapies are rarely effective in patients older than eight years of age.
Therefore, Blaha decided to use VR and Leap Motion to train his brain to adapt to the symptoms in both eyes, thereby improving his vision. Within a week, he was able to perceive stereoscopic depth and read using his strabismic eye (the non-dominant eye).
Clinical trial results indicate that the Vivid Vision treatment regimen not only improves visual acuity but also enhances patients’ depth perception. Andrea, a 35-year-old patient, reported that when she first launched the “Bubbles” game in Vivid Vision, the visual experience seemed unusual; only after describing this sensation to her physician did she realize it was her first time perceiving 3D depth.
In the study, the mean LogMAR visual acuity score of children under 11 years of age improved from 0.23 to 0.06 (with 0.0 representing perfect visual acuity), indicating that these children with amblyopia achieved near-perfect vision after treatment.
