What is amblyopia? Amblyopia is a condition in which the best corrected visual acuity is below the visual acuity level of children of the same age, or the difference in visual acuity between the two eyes is more than 2 lines, due to monocular strabismus, uncorrected high refractive error, refractive aberration, and form deprivation during visual development. How to detect amblyopia early? 1. The visual acuity of children under 3 years old is not up to the standard: the visual acuity of children under 3 years old is less than 0.5; the visual acuity of children 4-5 years old is less than 0.6; the visual acuity of children 6-7 years old is less than 0.7; 2. What are the dangers of amblyopia? For amblyopic children, if the amblyopic eye is not treated in time, the vision cannot be improved, which will seriously affect their learning; amblyopia will cause the development of stereoscopic vision disorder, so the patient cannot accurately judge the orientation, position and distance of objects, which will affect the future life of the patient and the choice of occupation. How is amblyopia treated? Remove the cause of amblyopia as soon as possible, such as wearing appropriate glasses or having surgery to correct strabismus, congenital cataract surgery, etc.; insist on personalized and effective amblyopia training; review regularly to avoid recurrence. How to detect strabismus in children at an early stage? Parents should pay more attention to their children’s behavior in life, such as children are afraid of light, tearful, like to squint one eye in the sunlight; children are prone to serial reading, blurred vision and sometimes double vision when studying; often tilt their heads when looking at things; myopia is growing faster. Why is it necessary to treat strabismus? 1, affect the aesthetics, and may affect the psychological health due to the abnormal appearance, thus causing their isolation, low self-esteem; 2, cause amblyopia, strabismus patients are prone to the formation of strabismic amblyopia, resulting in poor vision in the strabismic eye; 3, loss of stereo vision, affecting career choice; 4, skeletal development deformity, some strabismus patients, due to eye muscle paralysis, often use the crooked head, side face and some other special head position, if not early If strabismus is not corrected early, it will lead to deformities of the whole body skeletal development, such as scoliosis of the spine and asymmetric facial development. How to treat strabismus? Except for a small percentage of internal strabismus, most strabismus requires surgery; the main goal of strabismus surgery is to restore binocular vision, but it is also an aesthetic procedure, so minimally invasive strabismus surgery with minimal trauma and quick healing is needed; it is important to assist with the necessary functional training after surgery. What are the risks of myopia in children? Myopic children have difficulty seeing far away from their eyes, which makes life and learning difficult; they are prone to visual fatigue, which affects their academic performance; if not corrected in time, it can lead to exotropia, which can affect stereopsis development; as children are growing and developing, once they have myopia, they tend to develop quickly, and if they progress to high myopia, the risk of blindness such as retinal fissures and retinal detachment increases significantly. How to prevent and control myopia? How to effectively prevent and control myopia in children? Early detection and treatment; individualized prevention and control measures based on the patient’s specific conditions, such as taking into account the child’s genetic factors, eye habits, sports habits, nutritional status, adjustment function and growth rate; scientific refractive correction glasses; strict control of indications and timely prescription of keratoplasty lenses to control the rapid development of myopia; active treatment of diseases that cause rapid myopia growth, such as abnormal Actively treat diseases that cause rapid myopia growth, such as abnormal binocular vision, fusion hypofusion and intermittent exotropia; choose the right time to perform posterior scleral reinforcement to avoid the continuous progression of high myopia; increase the time of outdoor exercise, strengthen nutrition, and do not deviate from the diet; train visual function and relieve fatigue; and review regularly. Can congenital nystagmus be treated? Yes, it can be treated. Treatment can reduce the nystagmus to improve visual acuity and improve visual function. How is congenital nystagmus treated? Some congenital anomalies can be treated surgically, such as congenital cataracts, congenital corneal clouding, etc. Most patients have a combination of refractive error, which requires glasses. For patients with congenital nystagmus who do not need to tilt their heads to see, the nystagmus can be reduced through a procedure called “extraocular muscle proprioceptive resection”. Why do children need “contact lenses”? The need to improve vision. High astigmatism is the most common cause of amblyopia, but frames are limited in their ability to correct it and “distort” it significantly. With RGP contact lenses, a unique tear lens is formed between the lens and the spectacle, which provides good vision correction and high patient comfort; the need to balance both eyes and develop stereopsis. If the difference in refractive error between the two eyes is more than 250 degrees, and the difference in the size of the object after correction with frame glasses is more than 5%, it will prevent the formation of stereopsis. But wearing “contact lenses” can avoid the above phenomenon; the need to control the rapid development of myopia. Corneal shaping lenses are special contact lenses that are worn at night and are a more effective means of controlling myopia.
