The prevalence of strabismus in children is about 2%, and the earlier the onset of strabismus, the greater the impact on visual acuity and binocular visual function. Through a large number of cases of children’s strabismus surgery and synthesizing the surgical experience of famous pediatric ophthalmologists at home and abroad, we have summarized the norms of children’s strabismus surgery treatment. 1.For strabismus appearing sexually before the age of one, the surgery should be performed before the age of three after the amblyopia is cured. 2.Strabismus appearing in early childhood should be operated early when it has influence on binocular vision function. 3.Internal strabismus and exotropia with strabismus ≥15△ and vertical strabismus ≥10△ are the starting point of surgery. 4.If the vertical strabismus is <10△, but the hypotropia is obvious and the head is tilted, hypotropia reduction can also be performed. The effect of hypotropia reduction is closely related to the degree of hypotropia. In other words, the more significant the hyperactivity of the inferior oblique muscle, the more significant the effect of reduction surgery; the lesser the hyperactivity of the inferior oblique muscle, the lesser the effect of reduction surgery. If the degree of hyperactivity of the inferior oblique muscle is not symmetrical in both eyes, increasing the amount of surgery on the inferior oblique muscle for those with obvious hyperactivity will not achieve the effect of balance on both sides. 5. Rotational deviation of more than 10 degrees suggests the presence of bilateral superior oblique muscle paralysis. For common external rotation strabismus, Harada-Ito surgery of the superior oblique muscle can be considered. 6, Idiopathic nystagmus compensates for the head position with more than two lines of visual acuity improvement than the first eye position, and surgery can be chosen.
