In the face of heavy schoolwork and unavoidable electronic products, how to grasp the child's vision health? Here, optometrists emphasize; Myopia can be prevented and controlled, incurable, prevention is the top priority, to children and adolescents to establish and improve the refractive development file, is an effective myopia early warning method.
Children's vision development is a process of growth, just like the height development from low to high, with age, the development of the eyeball also goes through the process of eye axis from short to long, vision from farsighted to square vision.
The eye axis is the distance between the front and back diameter of the eyeball, when the child is just born, the eye axis is generally about 18mm, the average growth of the eye axis in the first year is 2.5 to 3.5mm, the third year after birth can reach 22mm, and the 5-year-old is close to adulthood. Under normal circumstances, the eye axis changes from 5 to 15 years old are very small, usually no more than 1 mm. After the age of 18, with the end of the growth and pronunciation period, the eye axis reaches about 24 mm, and the growth will generally stop or basically stop. If the eye axis grows at an overdrive, it becomes myopia, and the possibility of pathological myopia is not excluded.
Establish a standardized refractive file to detect eye refractive errors such as high hyperopia, myopia, astigmatism and amblyopia as early as possible. Early detection of eye disease in infants and young children. To check the refractive state of your child's eyes, you should check the ophthalmology department of a regular hospital. In addition to optometry, the ophthalmologist will check the child's eye position (to determine the presence of strabismus), lens (to determine the presence of congenital cataracts), and fundus (congenital glaucoma or other fundus lesions) at the same time, which is equivalent to a comprehensive physical examination of the baby's eyes.
From the age of 3, children should establish a refractive development profile. Children aged 3 to 12 years and adolescents under 18 years of age are actively targeted for refractive examination every 3 to 6 months. It will have a multiplier effect with half the effort. Refractive development file safety generally includes recording and tracking naked eye vision wearing glasses car positive vision, photogram optometry and computer refraction, eye axis, fish membrane curvature, eye position, intraocular pressure, anterior segment health status, etc., each examination result can be compared with the normal value of the same age and themselves, if the relevant indicators are abnormal, you can timely warn and take relevant measures.
Xi'an Aier Eye Hospital, located at No. 6 Zhangba East Road, Yanta District, Xi'an City, is a regional ophthalmic diagnosis and treatment hospital built in accordance with high standards in northwest China. The hospital covers an area of 13,000 square meters, with 101 beds and 4 clean laminar flow operating rooms. Led by Professor Hao Yansheng, a well-known ophthalmologist in China, the backbone medical team of the hospital is composed of masters and doctors, with cataracts, glaucoma, fundus diseases, ocular surface and corneal diseases, oculoplastic surgery, strabismus and pediatric ophthalmology, refractive surgery, medical optometry, function and morphology and other ophthalmic sub-professional departments.
