Escape from the flat world, 3D technology helps visually impaired children regain their "three-dimensional sense"

Amblyopia is the second most common eye disease in children. If the child does not receive timely and effective treatment, not only will he or she have low vision, but he or she will also live in a nearly flat world for the rest of his or her life, without a sense of three-dimensionality. The visual perception 3D system, which has been used clinically in China for nearly five years, has been proven to effectively help amblyopic children restore good binocular vision function and regain a "sense of three-dimensionality". Let's learn more about the relevant content with the editor of Medical Electronics.

Escape from the flat world, 3D technology helps visually impaired children regain their "three-dimensional sense"

The reporter recently saw in the examination room of the eye muscle department of Beijing Tongren Hospital that 5-year-old Binbin (pseudonym) was wearing polarized 3D glasses, staring at the circle and cross symbol on the screen, and slowly moving the mouse with his right hand, trying to put the cross symbol into the circle. "Okay, I put it in!" Binbin happily clicked the left mouse button to confirm, but the reporter clearly saw that there was still a distance of nearly 2 centimeters between the two symbols on the screen. Soon, the system popped up the result, showing that the eye position threshold was offset by 15 degrees.

"Strabismus, refractive error, anisometropia and form deprivation are the four major causes of amblyopia in children." Fu Jing, director of the ophthalmic muscle department of Beijing Tongren Hospital, said that using the visual perception system, doctors can more accurately perform seven tests on children, including binocular perception of eye position, distortion, stereopsis, etc. Based on the test results, professional technicians will design a personalized treatment plan and use interactive algorithms to generate biological image information. Children can receive treatment in the hospital or at home. After logging into the computer system, they can wear 3D glasses for online training. "Parents generally give good feedback. They feel that the new training system is more interesting, children are more willing to do it, and the recovery effect is also good."

Binocular vision is the basis of many precise movements in daily life and work. The golden period for binocular vision development is before the age of 2, and it basically stagnates at the age of 13. If a child with amblyopia does not develop binocular vision before the age of 13, the world in his eyes will be blurry and flat, and he will not be able to judge three-dimensional structures and distances. Fu Jing introduced, "The traditional method of correcting amblyopia is mainly to wear vision correction glasses, combined with treatment methods such as occlusion and tool training. The focus is on restoring vision, but ignores the establishment of binocular vision."

Beijing Tongren Hospital has used this technology to examine and treat about 300 children. Among the patients who have completed the examination and received treatment for a period of time, the children's vision has improved significantly, especially the recovery of binocular vision function. At present, this technology has been included in the health science and technology achievements and appropriate technology promotion projects of the Beijing Municipal Health and Family Planning Commission, and has been promoted to 8 hospitals in 8 districts and counties in Beijing.
