The summer holidays are over, and the days of getting up early and coming home late are as busy as a war are finally over for now. The biggest feeling during this vacation is that there are too many patients, so I don’t have enough time to communicate with parents who are anxious to see their children’s vision decline. Here, I would like to give some simple answers to some of the questions that parents are most concerned and most eager to know.
There are many reasons why more and more children are experiencing astigmatism.
1. As children now use their eyes too early, they often watch TV and learn to draw for a long time within three years old, and use their eyes excessively; while the eye development is the fastest within three years old, the eye development is in immature stage, and most children have combined astigmatism and farsightedness, so if they use their eyes excessively, it not only makes their eyes develop in the direction of myopia, but also often causes an increase in astigmatism;
2. Many infants and toddlers have a combination of impingement, ocular eczema, conjunctivitis or ptosis, so children often rub their eyes, tear and squint, which is also an early cause of astigmatism;
3. Poor physical condition and picky eaters can cause astigmatism due to nutritional imbalance, resulting in abnormal eye development;
4, the child’s eye posture is not correct. Squinting, squinting, and head tilting are often signs of astigmatism, and are also causes of increased astigmatism;
5. The presence of astigmatism in the parents. Genetic factors are also one of the mechanisms of astigmatism;
After the occurrence of astigmatism, a certain degree of astigmatism can lead to abnormal eye function, as the child’s vision is still in the developmental stage. The dangers of astigmatism are as follows.
1, leading to myopia. Astigmatism often leads to myopia due to the principle of visual defocus because of the difficulty of imaging objects on the retina; therefore, for many children who have astigmatism but still have good vision, it is most important to prevent myopia and eye fatigue;
2. Causes amblyopia. Due to the presence of astigmatism, if the child is unable to image objects on the retina, it will lead to meridian amblyopia. Therefore, prevention and treatment of amblyopia caused by astigmatism is most important for children over 3 years old and up to 7 years old;
3. Strabismus occurs. Most children, due to the presence of astigmatism, will have a certain compensatory head or eye position, such as skewed head, squinting eyes. This situation tends to deepen astigmatism and lead to strabismus;
What are the precautions to take after astigmatism occurs?
1, further refractive examination to clarify the child’s astigmatism refractive development state machine astigmatism on the vision hazard; and then take effective measures;
2. Change the child’s eye habits and picky eating habits. Do not rub the eyes and squint and squint to see things;
3, regular astigmatism examination. Children’s astigmatism changes more slowly than myopia, but in the course of their lives will also develop towards a certain pattern, such as cis-rational astigmatism gradually increases and decreases, and crystal compensation gradually decreases;
4. Wearing glasses reasonably. Astigmatism wearing glasses purpose in addition to correct vision, the most important is to relieve visual fatigue. Therefore, we are not only concerned about the improvement of the child’s visual acuity, but most importantly, whether the child is in a normal visual state.
A few concepts about astigmatism:
1. There are physiological and pathological astigmatism. Physiological astigmatism generally does not develop, but only some physiological changes with age. However, pathological astigmatism will gradually increase.
2. Astigmatism cannot be corrected by medication or prescription lenses at present. Therefore, wearing glasses is to improve visual function and prevent complications from arising. However, for an adolescent child, it is especially important to wear glasses because the vision is in the perfect and mature stage;
3. Children with astigmatism often have a combination of binocular vision abnormalities, so they often have a crooked head to see things. Therefore, many children with TV squint have a combination of astigmatism;
