This is a problem for many parents. Many babies in infancy have what appears to be strabismus, but it’s not, it’s what they call “opposite eye”. In most cases, this is because the nasal bridge has not developed and the inner canthus is blocking the white of the eye on the nose. In a small number of children, the position of the eye is really abnormal, which requires a doctor’s examination to confirm, and cannot be treated immediately after diagnosis. Why can’t intervention begin until the age of three? Because, the treatment of strabismus is first to correct the refraction, that is to use glasses to solve, the degree, and then to see if the strabismus can return to normal, if it does, there is no need for surgery, if it does not restore the eye position, then only talk about surgical treatment. Therefore, strabismus is not always treated surgically once it is diagnosed. Children as young as three years old can cooperate with the doctor’s examination, including the identification of vision charts, cooperation with various instruments, eye position examination, etc. Many tests cannot be performed when the child is too young, so of course the diagnosis cannot be confirmed, not to mention how to choose a treatment plan. If a child needs immediate surgery, the body’s ability to adapt to the stress of general anesthesia and the ability to cooperate with medical care before and after surgery can all meet the standard. For children older than three years old, once strabismus is diagnosed, it is better to first determine if it is caused by a problem with the eye muscles, and if so, to operate as soon as possible, and if not, to treat the cause. Regarding strabismus surgery, adults can adjust the surgical plan at any time under local anesthesia, and most of them can be solved in one surgery. In contrast, children are operated under general anesthesia, and the eye position changes immediately after the anesthesia takes effect, so it is impossible to judge the eye position intraoperatively, let alone adjust it, so the surgery can only be performed according to the plan designed by the surgeon before the surgery. Individual differences are always a problem in the medical field, that is, the same treatment, implemented in different individuals with the same symptoms, the results will be completely different. Therefore, parents of children should first be prepared that strabismus surgery may be performed twice or even three times to obtain satisfactory results. Amblyopia, the concept is the best corrected visual acuity. A child with low vision, if it can be adequately corrected to normal indicators, is no amblyopia, if the correction is less than normal, then there is no doubt that amblyopia. Usually myopic children rarely form amblyopia, so amblyopia is generally hyperopic, astigmatic children will get. There is no easy way to treat amblyopia, which is to correct the vision with glasses after adequate dilatation, and then insist on eye shielding and amblyopia training. Special emphasis should be placed on the fact that amblyopia treatment must be completed best before the age of 8. After the age of 8, it is difficult to make progress and there is little chance of recovery. This means that parents should not wait for amblyopia to be detected and start treatment early, leaving as much time as possible between the ages of 8 and 8. What is my child’s visual acuity? It is impossible to know exactly what the vision of an infant is like after birth because the eyes follow the object. If necessary, a VEP can be used to assess the child’s vision. After one and a half years of age, a child’s visual acuity can be measured only if the child knows the patterns of fish, quilts, umbrellas, flowers, scissors, etc. After 2 and a half years of age, a normal visual acuity chart can be checked when the child can distinguish between up and down, left and right. It is not correct that many parents are overly concerned about the results of the vision test. Vision itself is a subjective indicator, which is affected by the psychological state of the person being tested and the test taker, in addition to physical state, mental state, light, distance and many other factors that affect the vision test, so doctors do not pay much attention to the results of the vision test, which is only used as a reference indicator. For example, a person with 0.2 vision may have 200 degrees of myopia or 400 degrees of myopia; a child with 100 degrees of myopia may be able to see 0.8 or 0.3 because of the difference in adjustment ability; what is important is not the results of the vision chart but the results of the optometry. Many hospital doctors are eager to quickly dilate the pupil, check the vision and examine the light. In fact, this is a waste of time for both sides. The measured prescription after fast dilatation still does not indicate the true prescription and is meaningless. Slow dispersion is the only reliable way to understand the true condition of your child’s refraction. Slow dispersion is inconvenient, as the child needs to be medicated for three days and then go to the hospital on the fourth day for an optometric examination, which is the most realistic result for the child. However, it takes close to 20 days to recover the pupil size, during which time the child cannot see bright light, needs to wear sunglasses, cannot see near things, and cannot read and do homework, so usually slow dispersion can only be implemented during holidays, otherwise it affects learning. For example, I’ve seen children with a maximum of 300 degrees of myopia become 225 degrees after fast dispersal and disappear completely after slow dispersal! This is pseudomyopia, which requires medication and eye rest to consolidate the results of pupil dispersion. It is also necessary to review after six months of vacation and slow dispersion again if necessary. This is troublesome and inconvenient, but it’s better than wearing glasses for real myopia, right? Of course, if the result of slow dispersion is still myopia, then unfortunately, your child has myopia and needs glasses to correct his or her vision. This correction is not after what means the child does not need to wear glasses, but the use of glasses so that the child wears glasses vision normal, convenient for daily life and learning only. 18 years old after the child can consider laser treatment myopia removal, before this method is not discussed. 13 years old after the consideration of wearing OK lenses, which is similar to contact lenses at night to sleep, corneal contact lenses, daytime vision can be normal without glasses to correct vision. OK lenses are not a real cure for myopia, but a temporary removal of myopia during the day through nighttime corneal shaping to achieve normal vision. The original vision and prescription is restored after a few days of not wearing them. It works well and can prevent myopia from growing too fast, but the risk is fatal, once you get keratitis, that is the serious type of keratitis that rapidly develops into an ulcer, the condition develops rapidly and ferociously, too late to treat, the consequences are severe. Children under the age of 13 have no choice but to wear glasses with frames. To sum up, if you suspect that your child has a problem with his or her eyes, go to a regular hospital as soon as possible and get a thorough examination according to the normal treatment routine, so as not to delay the valuable treatment.
