Also known as strabismus, the cause of strabismus is related to heredity, but some strabismus is

Acquired sexual orientation

By, for example

extraocular muscle

Paralysis, or tissue fibrosis and imbalance; Or because of brain diseases, it is impossible to control the function of extraocular muscles, resulting in eye position deviation.

Except that the prepared glasses can deduct a certain degree of strabismus

There are two ways to cure it.

One is to do training

The second is surgery.

It depends on what kind of strabismus you have

You can consult a doctor for details.

Strabismus refers to both eyes.

ray axis

Incorrect, there are deviations from inside to outside and from top to bottom. Normal people's eyes should be parallel in front. When looking at an object, the image of the object falls on the retina of both eyes.

Macular fovea

In fact, it is the fusion ability of the brain that makes the images seen by two eyes merge into one. When strabismus patients notice an object due to incorrect eye position, the image of the object falls on the fovea of the normal eye.

squint

The eyes fall outside the fovea of the retina, so that visual objects will appear.

diplopia

Situation; The image of one eye is suppressed, losing the single visual function and stereoscopic impression of both eyes, and some will lead to poor vision and amblyopia. So strabismus is not only an aesthetic problem, but more importantly, if it is not treated in time, it will often cause strabismus.

be unable to recover

Abnormal visual function and amblyopia.

Strabismus can generally be divided into

Convergent strabismus

、

exotropia

Strabismus up and down

(1) esotropia: commonly known as cross-eyed. The eye position is shifted inward. Clinically, it can be divided into congenital and acquired strabismus. What happens between birth and birth is called

Congenital esotropia

. The deflection angle is usually large. Acquired esotropia can be divided into accommodation and non-accommodation.

Accommodative esotropia

Most of them are 2-3 years old, usually accompanied by medium height.

long sight

, or abnormal adjustment

cohesive force

And regulation ratio; Nonaccommodative esotropia and

Regulating force

It has nothing to do with refractive status.

(2) exotropia: that is, the deviation of eye position, which can be generally divided into intermittent and persistent exotropia.

intermitent exotropia

Because the patient has good image fusion ability, most of the time the eye position can be maintained in the normal position through image fusion ability, only

sometimes

Only when you are in the sun, or when you are tired and careless, do you show your eyes looking out. In order to avoid diplopia caused by exotropia, some children

The sun is shining.

regular meeting

Close one eye.

Eyes. Intermittent exotropia often develops into persistent exotropia, while occasional exotropia becomes persistent exotropia.

(3) Up-down strabismus: that is, the eye position inclines upward or downward, which is generally rare. Strabismus is often accompanied by head tilt.

The treatment of strabismus varies according to the type of strabismus, which can generally be divided into surgical treatment and non-surgical treatment.

(a) the surgical treatment is adjusted by the surgical method.

eye muscle

The strength and the position of the attachment point make the eye position tend to be normal. Congenital esotropia and strabismus mostly require surgical treatment, which is not accommodative.

Tilt degree

Large strabismus usually requires surgical correction.

(2) Non-surgical treatment: Not all strabismus needs surgical treatment. If it is accommodative esotropia, just wear appropriate hyperopia glasses or

Double optical mirror

It can be corrected. If there is no junior high school

Refractive abnormality

It is often necessary to wear glasses for correction, and in addition, axial correction training can help the recovery of monocular vision and increase the ability of image fusion. For example, training with a visual axis correction training machine, or wearing prism lenses. If there is amblyopia, amblyopia training is also an essential treatment.
