Changsha Evening News, Changsha, February 1 (Correspondent Wenbo) 13 years old, should be an innocent age, happily studying and living, but Tongtong (pseudonym), who has just entered the second year of junior high school, has been living in a hazy vision because he has suffered from ultra-high myopia since he was a child.
When he was 4 years old, his myopia was as high as 900 degrees, and the child always mistook his father.
When Tongtong was 2 years old, she always liked to squint and stand in front of the screen to watch TV, and after her parents reminded her many times, she would still involuntarily come closer to watch; When going out with his parents, the child always recognizes his father for himself. At that time, his father was fatter, and when the child saw his fat uncle, he ran over and called his father. Tongtong's mother, Ms. Zhang, recalled.
At first, the parents thought that the child was young and ignorant, but as Tongtong often rubbed her eyes and walked and often wrestled, this aroused Ms. Zhang's vigilance. She took the young Tongtong to the hospital for examination several times, but because Tongtong did not cooperate with the examination, she returned fruitlessly.
Two years later, 4-year-old Tongtong went to the hospital again for examination, and the doctor said that her eyes were short-sighted, and both were as high as 900 degrees, and since then she has been wearing thick and heavy glasses.
Since then, the myopia of school-age Tongtong has still grown rapidly, increasing by more than 100 degrees every year, the lenses are getting thicker and thicker, affecting the appearance, the child has become very shy, and the hobbies are also restricted, and parents are more anxious about the child's eye health and worry about various complications of high myopia. Ms. Zhang took Tongtong to many hospitals, and the answers she got were that there was no better ** and intervention method except for the child's glasses control.
The surgery puts "armor" on the child's eyes
After many inquiries, the parents found Lin Jiang, a pediatric ophthalmologist from Sichuan Eye Hospital. After a detailed examination by Lin Jiang, the axial length of the left eye of 13-year-old Tongtong was 30 mm, and the axial length of the right eye was 29 mm (most normal axial lengths were 23.)5 to 24 mm, for every 1 mm of growth, the myopia increases by about 275 degrees), the myopia degree in both eyes is up to 1600 degrees, and the unaided visual acuity is only 005, significant arcuate spots can be seen in the fundus, the retinal veins in the fundus are atrophied and thinned, showing leopard sign changes, and the peripheral non-oppressive leukodegeneration.
Lin Jiang patiently alleviated the anxiety of parents. She explained that myopia is irreversible, but it can be prevented and controlled, and the top priority is to help children personalize the progression of myopia control and avoid irreversible damage to visual function caused by pathological myopia complications.
Due to the growing eye axis of patients with high myopia, the human eyeball is like a "balloon" that blows up bigger and bigger. The "white shell" (i.e., sclera) of the eyeball has a fixed size, the growth of the eyeball is too fast, far beyond the normal range, and the various layers of the eyeball cannot grow at the same time, such as the local choroid, retina will be thinned and atrophied, and it is easy to have retinal tears or even retinal detachment, retroscleral staphyloma, macular splitting or hemorrhage, neovascularization and other complications, and strenuous exercise, excessive eye use, etc. should be avoided.
At present, "posterior scleral reinforcement" is an important surgical method to control the progression of pathological myopia. The mechanism is to mechanically strengthen the sclera, thicken and strengthen the eye wall, slow down the rate of axial growth, and thus slow down the progression of myopia; It can also improve the blood circulation of the choroid and retina, improve visual function, and prevent or reduce the occurrence of serious complications.
After Lin Jiang patiently explained the condition and suggestions to Tongtong's mother in detail, Tongtong's mother and Tongtong understood the principle of surgery and were very willing to accept the operation**. After a perfect preoperative routine examination, Lin Jiang was the chief surgeon, and with the full cooperation of the operating room and the anesthesiology department, he performed "bilateral posterior scleral reinforcement" under general anesthesia for Tongtong. The surgery was a success, and Tongtong was discharged from the hospital and had regular follow-up visits as instructed by the doctor.
Take care of the bright future of children with professionalism.
Lin Jiang introduced that before the age of 6 is the critical period of children's eye development, and problems must be dealt with in a timely manner, especially children with high myopia. Whether it is congenital or acquired factors, the axial lengthening, the collagen synthesis and decomposition disorder in the sclera, the sclera thinning and unable to resist intraocular pressure, the appearance of posterior scleral staphyloma, fundus macular neovascularization, hemorrhage, choroidal atrophy and other eye diseases, corrected vision deterioration, visual field defects, decreased central vision, blindness, etc., will seriously affect the child's eye health, and need early detection, early intervention, and early **.
Lin Jiang said that children and adolescents with rapidly developing progressive myopia, with an annual progression of more than 100 degrees, an eye axis greater than 26 mm, and the formation of posterior scleral staphyloma with or without vision loss; Posterior scleral reinforcement is done as soon as possible to improve fundus microcirculation and protect visual function, which is of great significance for reducing serious fundus complications of high myopia and avoiding low vision or blindness. "Posterior scleral reinforcement" uses the reinforcement material to integrate with the own sclera, change the biomechanical characteristics of the original sclera, and prevent further expansion of the eyeball and progressive lengthening of the eye axis.
