What is strabismus? It is a condition in which the visual axes of a person’s two eyes are not parallel. Strabismus can be either congenital or developed after birth. According to the manifestation of strabismus, it is divided into internal strabismus, external strabismus, vertical strabismus and other special types of strabismus. Internal strabismus and exotropia are more common in clinical practice. Strabismus is not only cosmetically unsightly, but also causes loss of “stereoscopic” (three-dimensional vision) perception, and because the brain suppresses the image messages received by the strabismic eye, most strabismus will lead to amblyopia if it occurs in infancy or childhood. The severity of amblyopia due to strabismus varies, and some severe amblyopia is legally defined as equivalent to blindness. Treatment for strabismus 1. The child should go to a regular hospital for an eye examination at the age of three, including visual acuity, fundus, and the presence of strabismus. If the examination reveals unequal or widely different visual acuity in the eyes, immediate dilated pupil examination should be conducted to clarify whether there is refractive error, and if so, timely correction and insistence on wearing glasses. If you wait for your child to grow up and then treat, you will miss the best time for treatment. 2, amblyopia training Children with strabismus, if conditions permit, it is best to go to the hospital for stereoscopic or synoptic machine training. Children with strabismus have their vision corrected after wearing glasses, but the visual function of both eyes is often still impaired. These trainings not only help a lot to correct the position of strabismus, but also play a good role in the recovery of visual function of both eyes and the establishment of stereoscopic perception. 3.Surgical treatment Children who are not effective or still have strabismus after 1 to 2 years of treatment by the above methods, or those who are too late for strabismus treatment, need to undergo surgical correction on the basis of wearing glasses. For congenital strabismus, surgery is required around the age of 1 to 2 years, and for other strabismus, surgery can be performed at the age of 3 to 6 years depending on the specific situation. Pediatric strabismus surgery not only improves the appearance, but more importantly, restores the stereoscopic sense of the eyes, so the idea of waiting until the child grows up to have surgery is wrong.
