Strabismus and amblyopia are common diseases that affect children’s vision, and according to a survey, the prevalence of strabismus and amblyopia among children and adolescents in China has exceeded 1%. Strabismus refers to the asymmetrical position of the two eyes, with one eye focused on the target while the other is off the target. Although strabismus can occur at any age, it is most prevalent in children between the ages of 3 and 6. There are many causes of strabismus, both congenital and acquired, such as trauma, inflammation, tumors, and blood circulation disorders. Amblyopia is low vision, always below 0.9, regardless of the type of glasses worn. Most amblyopia is caused by strabismus, high myopia, farsightedness, astigmatism that has not been corrected for a long time, a large difference between the refractive states of the two eyes, and something blocking light from entering the eye for a long time during infancy. The eyes are the windows to the soul, the first of the five senses, and strabismus not only damages the image of the human body and negatively affects the child’s mind, causing low self-esteem and loneliness and affecting the normal development of personality and psychology, but strabismus can also cause amblyopia. Both strabismus and severe amblyopia can seriously affect the visual function of both eyes, resulting in a lack of stereo vision. The lack of stereoscopic vision may cause difficulties in driving, operating precision instruments, and performing delicate operations, which may limit the child’s ability to learn and choose a career as an adult. In addition, children with paralytic strabismus often have to tilt their heads and faces sideways to eliminate double vision, which affects the development of the child’s bones and can lead to spinal curvature if the head position is not corrected in time. How to find out if a child has strabismus or amblyopia? Usually, it is important to observe whether the two eyes are symmetrical, whether the two eyes are looking at the same time or whether there is a tilted head. It is also important to note that children who adopt a strange posture to look at things may also be a sign of strabismus, such as preferring to turn their heads sideways and rolling their eyes upward, which may indicate strabismus. In addition to correcting the eye position to improve the appearance, the treatment of strabismus is more important than functional treatment, including amblyopia treatment and the restoration of normal visual function in both eyes. During childhood, the visual system is in the vigorous stage of growth and development and has plasticity, the younger the age, the greater the possibility of restoring the function of binocular vision. After the age of 14, the cure rate for amblyopia is only 1-2%, and after adulthood, the cure rate is almost zero. At this time, strabismus surgery can only improve the appearance of the eye. Many children with amblyopia suffer from lifelong regrets because of delayed treatment. In addition, it is important to emphasize that the treatment of amblyopia is a long-term process, and it is normal to see no obvious results in a year and a half, and it takes up to 7-8 years to be cured, so don’t let your laziness cause great regret in your child’s life.
