Myopia: what is this disorder and why does it appear
Myopia in children occurs due to an abnormal structure of the eyeball. Normally, the eye has a non-ideal spherical shape, and the optical system of vision refracts light rays in such a way that they are focused on the retina. In this case, a person sees a clear image at different distances.
In the case of myopia, the eye has an elongated shape, and the higher the degree of impairment, the stronger the back wall of the eye organs is stretched. In this case, the refracted rays simply do not reach the retina and are focused on the area in front of it.
Because of this, the image at long distances is perceived blurry, and with a high degree of myopia, visibility deteriorates even at medium distances.
Experts distinguish three degrees of children's myopia:
- Up to -3 diopters - weak;
- Up to -6 diopters - medium;
- From -6 diopters - high.
Causes of myopia in children
- The hereditary factor plays a significant role in the occurrence of myopia. If both parents have visual impairments, with a 50% chance, myopia in a child will manifest itself even before adulthood. At the same time, the proportion of short-sighted children whose parents do not have vision problems is less than 10%. Science explains this by the heredity of defects in collagen, which is involved in the construction of the sclera - the outer shell of the eye organs, which is responsible for protecting and supporting the eyes;
- Increased stress on the eyes, which leads to overstrain of the visual system. It is for this reason that in most cases, myopia in children develops after entering school, when the load on vision increases significantly. Additional factors can aggravate the situation: an improperly organized workplace, lack of lighting, prolonged work at a computer and the use of mobile gadgets, too little distance between the eyes and a book or notebook;
- Weakening of the body due to diseases or birth injuries, improper lifestyle or poor nutrition.
Types of myopia
Specialists divide children's myopia into the following types:
- False - in this case, a significant decrease in visual acuity is indeed observed, however, it is not caused by an elongation of the eyeball, but by a spasm of accommodation of vision, that is, the ability of the eye to focus on objects near and far. This disorder is caused by problems with the ciliary eye muscle. False childhood myopia responds well to treatment - hardware and medicinal (special drops are prescribed). Also, gymnastics for the eyes, proper rest and breaks during study have a positive effect. But the use of glasses for vision correction with such a diagnosis can have negative consequences. If false myopia is not treated, it can later turn into true.
- True - can manifest itself at any age, while if there is a hereditary factor or prematurity, myopia is considered congenital. With true myopia, there is a change in the shape of the eye, which we wrote about above. If every year there is a deterioration in vision by one diopter or more, myopia is considered progressive. In this case, the child needs serious treatment and constant monitoring by a specialist.
Signs of myopia in children
Since myopia can manifest itself at any age, it is important for adults to monitor the behavior of children and recognize the first "bells" in time. Remember that a child may not be aware of their vision problems, simply not understanding how it should be normal. Therefore, ideally, children should undergo a preventive examination by an ophthalmologist at least once a year, and adults should promptly respond to alarming symptoms:
- The child often squints when looking at distant objects;
- There are regular complaints of headache, especially after eye strain - reading, doing homework, using a computer or mobile gadgets;
- The child brings the book close to the eyes, bends low over the notebook, comes closer to the TV to view the image;
- Blinking becomes more frequent, the child constantly rubs his eyes.
If you notice one or more symptoms, take your child to an ophthalmologist immediately!
Treatment of myopia in children
To combat the violation, conservative and surgical methods are used. The treatment strategy directly depends on the degree of myopia and its progression. If the annual deterioration of vision does not exceed 1 diopter, conservative treatment is prescribed.
Conservative treatments for myopia
The main measures in the treatment of myopia are primarily aimed at combating the progression of the disorder, unfortunately, the complete elimination of myopia is not always possible.
In order to prevent a further decrease in visual acuity, it is important to provide the eyes with proper rest, strengthen the eye muscles and diversify the diet. How can you help a child?
- Include in the children's diet foods that are rich in vitamins that are good for the eyes - seafood, fresh vegetables, fruits and berries (preferably blueberries, carrots, spinach, grapefruit, apricots, pumpkins);
- Perform eye exercises with your child, after consulting with an ophthalmologist on this topic. Classes with a small child should take place in a playful way, with the obligatory participation of adults, school-age children can study on their own, but it is important to control the regularity and correctness of the exercises;
- Make sure that the child sleeps enough and takes breaks while doing homework, using mobile gadgets and a computer, reading;
- Organize the child’s workplace according to all the rules: select furniture that matches his height (during classes, the child needs the opportunity to comfortably rest his elbows on the table without pulling his shoulders up and not slouching), provide enough lighting.
Glasses and lenses
Correction of vision in the fight against myopia plays a decisive role! If you do not provide the child with normal "visibility", he will be forced to constantly strain his eyes. As a result, myopia will continue to progress further, causing not only visual discomfort, but also headaches. This will affect both the health and well-being of the child, and his daily life - grades will begin to deteriorate, the desire to learn will disappear.
Therefore, the sooner the child receives an adequate correction, the higher the chances of stopping the progression of myopia.
With myopia, both glasses and contact lenses (CLL) are equally effective. It is preferable for small children to wear glasses, but MCL is recommended to be prescribed from the age of 10. Experts recommend choosing glasses with plastic lenses - they are not only lighter, but also safer: it is more difficult to break such lenses, but even if this happens, the plastic does not shatter into small fragments, which means that the risk of injuring the eye is much lower. Given the mobile lifestyle of children, such a decision will quickly justify itself.
Contact lenses also effectively cope with children's myopia. In this, soft contact lenses with controlled peripheral defocus OK VISION DEFOCUS CONTROL LENS, bifocal (defocus) lenses, have especially proven themselves. Such lenses can slow down the progression of myopia.
The effectiveness of stopping the progression of myopia with bifocal contact lenses can be compared with the effect of orthokeratological lenses.
Night contact lenses for myopia control
Special orthokeratology lenses (OK lenses) are used only at night. The child sleeps in lenses, and takes them off in the morning, while good vision returns for the whole day. Night lenses contribute to the temporary correction of the shape of the cornea. OK lenses act on the center of the outer surface of the eye, making it flatter. Due to this, during the night, the corneal cells are gradually shifted to the periphery.
The essence of the orthokeratology technique is the redistribution of the surface cells of the cornea by pressing it down with the help of special lenses. Correction with OK lenses can slow down the progression of myopia in children.
Contact lenses, although recommended from the age of 10, have no age restrictions. This means that even first-graders can wear them. The main thing is that the child knows how to care for products and understands the importance of this. He must also be meticulous about personal hygiene, keeping lint or dirt out of his eyes, and handling lenses carefully so as not to inadvertently damage products.
Parents also need to monitor the timely replacement of lenses and compliance with their wearing regimen. That is, after the expiration of the period of use, you must give the child new SCLs, and also control that, for example, he does not sleep in daytime lenses.
If you are not sure that the child will cope with the care of the lenses, or you are afraid of missing the replacement period, pay attention to one-day SCLs.
The selection of correction occurs only after a complete diagnosis of vision. In the future, the child needs to undergo a scheduled examination by an ophthalmologist every six months. All these types of myopia correction are available at the Megaoptica Happy Look medical center. Our ophthalmologists will conduct a thorough examination and select the necessary method of correction.
If myopia continues to progress, you may need to resort to additional therapy or surgery.
Hardware treatment of myopia in children
This method of therapy has positively proven itself in the fight against the progression of myopia. For hardware treatment, modern medical equipment is used, aimed at training the eye muscles and accommodation. "Happy Look" provides a comprehensive hardware treatment of myopia in children.
Surgical treatment of childhood myopia
If the disease progresses dynamically, and vision is reduced by one or more diopters per year, ophthalmologists are forced to resort to surgical intervention. Without this, the development of the visual apparatus occurs with disturbances.
The operation has to be resorted to in the case when complications appear, for example, dystrophic changes in the retina.
As a rule, children with progressive myopia or retinal dystrophy undergo scleroplasty. The procedure is aimed at strengthening the back of the eye, which improves the metabolism in the tissues of the visual organs, as well as preventing the further development of the disease and elongation of the eye.
Summarizing
- At least once a year, take your child for a preventive medical examination by an ophthalmologist. Also watch his behavior - complaints of headaches after eye strain, increased blinking, an unconscious desire to reduce the distance between the eyes and a book, screen or notebook are alarming calls that require the attention of a specialist;
- Properly organize the child's workplace, provide his diet with products that are useful for vision, monitor proper rest and control the time spent at the computer or mobile gadgets;
- Ask for vision correction - the child should pick up glasses or contact lenses. If lenses are prescribed for correction, make sure that the child properly cleans the products and observes the wearing mode;
- Do regular eye exercises with your child;
- Follow the dynamics of the development of myopia.
