Most astigmatism in children is caused by congenital development and cannot be cured by treatment. Most astigmatism originates from the cornea. Because the eye is susceptible to pressure from the eyelid during development, it affects the refractive power of the cornea and causes astigmatism in the cornea. In addition, if the cornea is traumatized, after eye surgery, or after corneal disease has healed, it can also cause acquired irregular astigmatism. Mild astigmatism has no effect on vision and therefore does not need to be treated. However, significant astigmatism can have an impact on vision, especially in children with astigmatism greater than 150 degrees, which can easily lead to amblyopia. Current ophthalmologists believe that when a child is 2 to 3 weeks old, he or she must go to a regular hospital ophthalmology department for a routine eye exam, the purpose of which is early vision screening. If abnormal visual acuity is found, or an abnormal refractive state, further medical astigmatism is required, and if it is indeed found to be caused by high astigmatism, glasses need to be worn in a timely manner to correct it, which can effectively prevent the occurrence of amblyopia. Therefore, if astigmatism is found in children, there is no need to panic, but be sure to choose the local regular hospital ophthalmology examination, follow the doctor’s instructions for timely correction.
