Cataracts are usually found in older people, but in recent years more and more children with congenital cataracts have been discovered. This may be due to the mother having a cold during pregnancy, for example. And congenital cataracts can then cause severe amblyopia. Amblyopia in children is a developmental disease. Zhao Jun told reporters that the main factors that cause amblyopia are: 1) strabismus; 2) refractive error; 3) form deprivation; 4) congenital cataract. ”The child’s visual development, 0-3 years old belongs to the critical period, before the age of 12 years old belongs to the sensitive period.” According to experts, amblyopia is actually a child with delayed and disturbed eye function after birth, resulting in visual impairment, which often may also be accompanied by strabismus, color weakness, no binocular monocular function, no stereoscopic sense, etc. Talking about the dangers of amblyopia, if not treated promptly and effectively, children will not only have difficulty learning to drive when they grow up, but also cannot engage in work related to mapping and various fine eye use. The most worrying thing is that many parents have very little knowledge about eye care, and less than 1% of children with amblyopia can really be treated effectively, making children’s vision decline year by year. The first thing you need to do is to take a look at the two eyes and see if they are in good condition. First of all, the pupils of both eyes are examined, the refractive error is fully corrected, and the refractive error of both eyes is adjusted according to the visual acuity of the amblyopic eye, and then glasses are prescribed. Then, the healthy eye once a day drops 1% atropine drops, forcing the amblyopic eye to look far or look close, in order to exercise the amblyopic eye, so that the amblyopic eye vision progresses. 2, wear needle and bead training: after the child wears corrective glasses, use red thread to wear needles or beads, each time wear 200-300 needles or 200-300 beads, prompt more near vision. To improve visual acuity. 3.Masking method: Masking method is the most commonly used method to treat amblyopia. This method uses a three-layer black cloth as a blindfold to cover the healthy eye, inhibit the dominant eye to force the amblyopic eye to exercise, according to the patient’s age and visual acuity, the nature of the gaze to determine the length of the cover. The younger the patient is, the shorter the duration of coverage. Atropine drops can also be used instead of covering. Atropine can temporarily reduce the distance and near vision, which is a disguised masking method. 4, after the image therapy: is the correction of paracentric gaze, improve vision method, the use of the protection of the central concave area of the fundus, with 3o, 5o, 7o round black dot after the image of the mirror, 6V15W strong light shine macular area, so that it produces after the image, suppress paracentric gaze, excite the central vision function, at this time to look at the visual mark (cross or visual acuity table can see the E word), twice a day, each time repeatedly do 2-3 times. 5, red filter method: the macular area of the fundus contains only cone cells, cone cells are sensitive to red light, forcing the central concave gaze, inhibit the paracentral area, there are many such treatment instruments in China, the filter wavelength is 620-700nm, raw minutes flashing 60-80 times is appropriate. 6, correction of amblyopia methods include drug therapy method: appropriate amount of supplemental trace elements zinc, copper, because it is related to the retina, optic nerve metabolism, also useful levodopa oral vision improvement, must pay attention to the use of methods.
