Early detection of amblyopia in children requires early treatment

Abstract: Recently, many parents consult children’s amblyopia through the Internet. So, what kind of eye disease is amblyopia? What is the reason for the formation, what is the harm, and how to prevent it? Amblyopia is a disease in which the best visual acuity of one or both eyes is lower than normal, but no ocular organic changes corresponding to the visual acuity decline are found.

clinically, amblyopia often shows that the best corrected visual acuity is lower than normal, strabismus, ametropia Crowding phenomenon (the ability to distinguish a single visual target is better than that of a line of visual targets when checking eyesight), lack of stereopsis, etc. in today’s increasingly fierce social competition, binocular visual function is abnormal, which indicates the reduction of employment opportunities, the reduction of the space to obtain knowledge and information and give play to personal ability. In serious cases, it will also produce certain psychological obstacles, which will create difficulties in their own image, work, education and making friends Negative impact.

causes of amblyopia

1 The different images projected on the macula of both eyes hinder the fusion of objects and images. In order to eliminate interference and binocular interaction, the brain selectively inhibits the visual information transmitted by the affected eyes, causing the suppressed eyes to form amblyopia. For example, in amblyopia caused by strabismus, the visual axes of both eyes are not parallel, resulting in abnormal retinal correspondence. There are great differences in the visual information and images collected by the macular fovea of both eyes on the same object, resulting in diplopia and visual confusion. In order to eliminate this interference, the visual cortex consciously inhibits the image information transmitted by strabismus eyes, In the sensitive period of visual development, the result of long-term inhibition is the decline of strabismus vision and the formation of amblyopia.

  2. Form deprivation, the quality of the object image projected on the macula is low, and can not form a focused image after brain processing. For example, in children with congenital cataract and complete blepharoptosis, above the critical period of visual development, these factors lead to insufficient light entering the fundus of the eye and forming a clear image, resulting in amblyopia of refractive interstitial opacity eyes. In how many cases, the formation of amblyopia is the result of the interaction of the above two factors, such as high ametropia, high myopia, hyperopia, astigmatism or anisometropia but not corrected in time, that is, there are factors of mutual inhibition of binocular competition and form deprivation factors of blurred images of both eyes. Generally speaking, amblyopia is easy to form when myopia exceeds – 10d, or the difference between two positive spherical lenses is greater than 1.5D, the difference between cylindrical lenses is greater than 1.0d, and the difference in myopia is greater than – 6D.

how to prevent amblyopia?

and

usually think that the visual system matures around the age of 3, and the visual development between the ages of 3-8 still has a certain plasticity, and even extends to a certain extent.) Therefore, the prevention and treatment of amblyopia should start with dolls, early detection and early treatment, and most children’s vision can still return to normal. Because children are naturally naughty and their attention is not easy to concentrate, it is difficult to accurately evaluate their eyesight. Here are some methods for parents.

  1. If the child is small and cannot check the visual acuity chart, you can use the color ball to shake in front of your eyes to see whether the child’s eyes move with the movement of the ball and whether the range of movement of the two eyes is consistent; If one eye is attracted, the other eye looks elsewhere, or the range of movement of the two eyes is different, you need to see a doctor to see if there is strabismus or ametropia, which leads to the imbalance of vision of the two eyes.

  2. Cover the children’s eyes alternately to see the children’s reaction. If the child’s left eye is covered, the child has no reaction and still plays as usual; When covering the right eye, there is obvious resistance, crying, grasping the cover with your hand and other reactions. It indicates that the right eye has good vision, the main eye, and the left eye may have amblyopia.

  3. Visual acuity chart method. Children should be taught to check their eyesight chart when they are about 3 years old. We can make use of children’s nature of being willing to be praised to encourage and praise more in the process of vision examination, so that they can cooperate with vision examination. For children suspected of amblyopia, comprehensive ophthalmic examination should be carried out to exclude organic diseases such as congenital cataract, vitreous hemorrhage, retinopathy of prematurity, as well as mild optic nerve hypoplasia, mild optic nerve atrophy and mild macular abnormalities, which are most easily ignored.

here, it should be emphasized that the key to vision development is visual stimulation. The development of visual pathways in the central nervous system requires the brain to receive equally clear and focused images from both eyes. Any lesion that seriously interferes with the development of brain visual pathway can lead to amblyopia. For example, children’s eyelids bitten by mosquitoes and flies, long-term edema and inability to open, or eye trauma, covering and bandaging the affected eye with gauze for a long time after intraocular surgery may cause amblyopia. For children with congenital cataract or congenital severe blepharoptosis, after surgery, everything must not be good, but amblyopia treatment. There are many methods of

and

to treat amblyopia, but the overall goal is only one: to enable patients to obtain the best vision. The first and most important step of treatment is to project a clear image on the fovea of the macular region. For children with deprivation amblyopia, we should find the exact cause and remove it. For ametropic amblyopia, children must wear glasses to correct this obvious ametropia. On this basis, children are encouraged to use amblyopia. They can use cover therapy, depression therapy and other ophthalmic treatments.

there are many factors affecting the curative effect, which can be summarized as:

1 Age of treatment: the earlier the age of treatment, the greater the possibility of vision recovery. Most of the effects of preschool treatment are better, and the effects are worse after the age of 9 or 11-12.

  2. Severity of amblyopia: according to the best corrected visual acuity of children, they can be divided into mild, moderate and severe cases: mild amblyopia with the best corrected visual acuity of 0.6-0.8; 0.2-0.5 is moderate amblyopia; Those less than or equal to 0.1 are severe amblyopia. Among them, the curative effect of mild amblyopia is good, followed by moderate amblyopia, and moderate amblyopia is the worst.

  3. Cooperation degree of parents and children’s compliance: first, parents should understand the treatment methods adopted by doctors, actively cooperate, encourage children and increase children’s compliance. For example, in the process of covering therapy, if parents do not understand or children are afraid of children’s ridicule,Or do not feel good-looking and other reasons, resulting in children often remove or uncover the eye mask to peep from the lens. These practices will reduce the effect of covering treatment, or even completely ineffective.

and

are always the most important early detection and treatment for the prevention and treatment of amblyopia. Parents and patients work together to achieve the therapeutic effect.
