1. Congenital esotropia: Infantile esotropia, also known as congenital esotropia, refers to esotropia occurring within 6 months after birth. The causes are mostly congenital ametropia, congenital medial rectus fascia abnormality, congenital lateral rectus paralysis, heredity and so on. The degree of ametropia is not great, and the eyes can often stare at the target alternately, which does not have the basic conditions for establishing binocular vision. Visual function development is the most harmful, and the best operation age is 6 months to 6 months. I will have surgery after I am 2 years old.

, often leaving different degrees of visual impairment. 2. Accommodative esotropia: It is caused by excessive accommodative convergence, which is often manifested as involuntary head deviation and neck deviation when children see things. It can be divided into complete esotropia and partial esotropia. Complete accommodative esotropia mostly occurs in 2-5 years old, mostly with moderate and high hyperopia. At first, esotropia only happened when staring at fine targets. Once wearing glasses, hyperopia can be corrected and strabismus can disappear, so glasses can be corrected in time without surgery. Partial accommodative esotropia usually occurs at the age of 65,438+0 ~ 3 years, often accompanied by hyperopia, astigmatism, anisometropia and so on. After wearing glasses to correct hyperopia, surgery is still needed. 3. Benign pseudoesotropia: How wide and flat is the nasal root between the eyes of infants, and the white part inside the eyeball is covered by the skin on the nasal side. It seems that dark circles are all located on the nasal side of the eyeball. This phenomenon can naturally recover with the gradual development of the bridge of the nose after the baby is four or five years old.
