Strabismus is a vision problem that many parents are concerned about because it not only affects the child’s appearance, but also causes amblyopia and scoliosis, so strabismus needs to be brought to the attention of parents. Because strabismus seriously affects the aesthetics of the patient, adults with strabismus are also prone to low self-esteem, affecting their work and even their friendships. Xiao Qiang, a strabismic child living in Haidian District, Beijing, is often nicknamed by his classmates, many of whom call him cross-eyed, thus casting a shadow over his psychological development and causing him to be withdrawn and have low self-esteem. Even if the visual acuity of the strabismic eye is normal, the visual field is not as open as that of a normal person, and most importantly, there is no image blending ability and stereo vision. For patients with paralytic strabismus, due to the paralysis of the eye muscles, they often adopt some special head positions such as deviated head and sideways face to overcome the discomfort when viewing objects, which is medically called “compensatory head position”. If not corrected early, it can lead to deformities in the development of the whole body, such as scoliosis of the spine. It can be seen that strabismus is not only a cosmetic problem for patients, so in order to reduce and avoid these complications, parents must take it seriously and achieve early detection and early treatment.
