What are the causes of strabismus? 70

It is closely related to refractive error and is often accompanied by farsightedness, myopia, or astigmatism.

Strabismus can be divided into two categories: common strabismus and paralytic strabismus.

Common strabismus**.

congenital factors;

Caused by functional abnormalities such as the brain's higher neural reflex activity and the accommodative fusion of the eye;

There is some relationship with genetics, but most patients with strabismus do not have a clear family history.

A common cause of paralytic strabismus.

Congenital anomalies, caused by lesions of the nerve nucleus innervating the extraocular muscles and the extraocular muscles themselves;

Certain diseases may cause intracranial tumors, cerebrovascular accidents, inflammation, trauma, diabetes, and orbital inflammation. Some patients with intracranial tumors have symptoms that only manifest in the eyes, and other symptoms appear later, so they should seek medical attention as soon as possible to avoid delaying the timing of intracranial tumors.

Glasses must be matched to a regular glasses line, I don't know if it is a problem with glasses, it is recommended to consult an ophthalmologist.

Most of the squints have the following three points:

First, the development of visual function is imperfect, and the extraocular muscles cannot be well coordinated, and external unstable factors, such as fever and fright, can promote the occurrence of strabismus.

Second, congenital anomalies, abnormal position of extraocular muscles can also cause punctate hemorrhage in the brain during childbirth, paralyzing extraocular muscles.

Third, the characteristics of eye development, children's eyeballs are small, the eye axis is short, most of them are farsighted, and because of the strong contraction ability of children's corneal lens nodal muscle, the coordination ability needs more inward turn, and excessive use is easy to lead to esotropia. Then we must protect our eyes in normal times, and we must develop good eye habits to avoid suffering from strabismus.

The causes of strabismus are, first, anatomical factors, that is, congenital anatomical abnormalities, including congenital esotropia and congenital exotropia, and congenital vertical strabismus is also related to it; the second is the accommodating factor, which refers to strabismus caused by abnormal refractive state; The third is the neural fusion factor, that is, after the child is born, the central nervous system is not fully developed, and his fusion cardinal function is insufficient, resulting in the two images can not be completely fused, and strabismus appears.

Strabismus can occur due to the following reasons:

1. Abnormal eye development. Many strabismus patients mostly occur in childhood, children's eyeballs are relatively small, the eye axis is relatively short, many are farsighted, coupled with children's cornea and lens refraction force is relatively large, ciliary muscle contraction force is also relatively strong, which is the ability to adjust is relatively strong, it will be very easy to lead to the occurrence of strabismus. Patients with strabismus need to accept more accommodation in order to see clearly, which will cause excessive divergence in the eyes, which will also cause esotropia.

2. Insufficient central control of eye movements. Esotropia occurs if the collection is too strong, the abduction is insufficient, or if both conditions are present. On the contrary, too much abduction and insufficient collection can cause strabismus.

3. Imperfect development. Many children will have imperfect development in infancy and early childhood, and there are some unstable factors that will easily cause strabismus.

4. Congenital anomalies. There are many patients with strabismus who are caused by congenital abnormalities, that is, the position of the congenital extraocular muscles is abnormal, the extraocular muscles themselves are abnormal, the mesoderm is not completely differentiated, and the separation of the eye muscles is not particularly good, etc., which will easily cause strabismus.

Depending on the type of strabismus, it can generally be divided into surgical and non-surgical methods.

1) The surgical method is to adjust the strength of the external eye muscle and the position of the attachment point by surgical means, so that the eye position tends to be normal.

Congenital esotropia (cross-eyed) and upper and lower strabismus usually require surgery**, and non-accommodative and oblique strabismus usually need to be corrected by surgery.

2) Non-surgical method: Not all strabismus requires surgery**, if it is accommodative esotropia, it can be corrected as long as appropriate farsighted glasses or bifocals are worn. If there is also a refractive abnormality of medium to high intensity, it is often necessary to wear glasses to correct it, and axial correction training can be used to help restore monovision and increase the fusion ability of both eyes.

If amblyopia is also present, amblyopia training is also indispensable**.

Strabismus caused by refractive error is recommended to take medication in time to correct the refractive error. It is recommended to take two sachets of Leyan Vision Nutrients every day, and if you insist on taking it for a period of time, the refractive error will gradually be corrected, and the strabismus will gradually improve or even recover.
