3D technology helps children with amblyopia regain "three-dimensional sense"
Release date: 2017-06-08
Amblyopia is the second-ranked disease in children's eye disease incidence. If children are not treated promptly and effectively, they will not only have low vision, but also live in a near-flat world for a lifetime without a sense of three-dimensionality. The visual perception 3D system, which has been used clinically for nearly 5 years in China, has been proven to effectively help amblyopic children to restore good binocular visual function and regain the "three-dimensional sense".
The reporter recently saw in the examination room of the eye muscle specialist in Beijing Tongren Hospital that the 5-year-old Binbin (a pseudonym) wore polarized 3D eyes, staring at the circle and cross symbol on the screen, slowly moving the mouse with his right hand, trying Put the cross symbol inside the circle. "Well, I put it in!" When Bin Bin was pleased to confirm the left mouse button, the reporter clearly saw that there was a distance of nearly 2 cm between the two symbols on the screen. Soon, the system popped up the results, showing that the eye position threshold was offset by 15 degrees.
"Squint, ametropia, anisometropia and form deprivation are the four major causes of amblyopia in children." Fu Jing, director of the eye muscle specialist at Beijing Tongren Hospital, said that with the visual perception system, doctors can more accurately perform on children. There are 7 items of eyesight, distortion, and stereoscopic vision. According to the results of the examination, professional technicians design personalized treatment plans and use interactive algorithms to generate bio-image information. The child can be treated at the hospital or at home. After logging in to the computer system, wear 3D eyes for online training. “Parents generally have good feedback and feel that the new training system is more interesting. Children are more willing to do it and the recovery effect is good.â€
Binocular vision is the basis for many precise movements in life. The golden period of binocular vision development is before the age of 2, and it is basically stagnant by the age of 13. If a child with amblyopia does not establish binocular vision before the age of 13, the world in his eyes will be blurred and flat, unable to judge the three-dimensional structure and distance. Fu Jing introduced, "The traditional method of amblyopia correction is mainly to wear vision correction glasses, and at the same time, with cover, tool training and other treatment methods, the focus is on restoring vision, and neglecting the establishment of binocular vision."
Beijing Tongren Hospital used this technology to examine and treat about 300 children. Among the patients who completed the examination and treated for a period of time, the children's visual acuity improved, especially the visual function recovery of both eyes was obvious. At present, this technology has been included in the Health Science and Technology Achievements and Appropriate Technology Promotion Project of the Beijing Municipal Health and Family Planning Commission, and has been extended to 8 hospitals in 8 districts and counties in Beijing.

The purpose of the sterilization box is to store the equipment in the process of packaging, sterilization, transfer, storage and so on. These orthopeadic instruments working mode is suitable for high pressure steam sterilization, not suitable for dry heat sterilization, ethylene oxide sterilization, ultraviolet sterilization, microwave sterilization and formaldehyde sterilization. The sterilization instrument box is divided into two parts,the cover and the body. The central area of the box cover is the filter system of the disinfection box, which is composed of quick filter system clasps and filter paper. The clasps need to be fixed by double keys, and the fixed sound can be heard during operation, which can effectively avoid the accidental loss of filter paper. Filter paper can be reused for 1 000 times, has chemical resistance, its chemical properties will not change with time, and its hardness exceeds steel. There is also a safety fit for the filtration system around the box cover, namely a silicone washer and a tension retaining ring. On both sides of the box there are handles, locks and sockets for indicating signs.
