Is strabismus hereditary?

Strabismus not only affects the normal vision of patients in life, but also causes problems when looking at distant objects or walking. Strabismus is a common disease in children. Once it occurs, it must be treated, otherwise it will cause the child's vision to gradually weaken and eventually cause hyperopia or myopia. Strabismus is also called cross-eyes, which will make the child's eyesight tilted when looking at things. Over time, it will become myopia and it is difficult to correct.

Is strabismus hereditary?

Strabismus is a common eye disease in children. Under normal circumstances, when we look straight ahead, both eyeballs are in the center position, and the positions of the two eyes are symmetrical when they turn in all directions. When one eye is in the middle when looking straight ahead, but the black pupil of the other eye is offset from the center, it is called strabismus. Strabismus can be divided into esotropia (commonly known as cross-eyed), exotropia (commonly known as squinting), hypertropia and hypotropia.

So how does strabismus develop? There are many reasons for strabismus. Some strabismus is related to genetics. One or both fathers have chromosomes causing strabismus in their genes, so it is inherited. Some strabismus is related to abnormal muscle development, while others are related to refractive errors. Strabismus can also be caused by colds, fever, trauma, intracranial lesions, myasthenia gravis, etc., which can cause movement disorders in one or more muscles of the eye, causing the eye movements of both eyes to become unbalanced, thus leading to strabismus. Strabismus is not only an eye disease that affects appearance, but more importantly, it can cause a serious decline or even loss of the patient's vision and binocular vision function.

Through what I have said above, I think friends have understood what strabismus is and how strabismus is formed. So it is not difficult to see that some strabismus is caused by genetics, while some is caused by other reasons besides genetics that I mentioned above.

The younger the age at which strabismus is treated, the better the treatment effect. Strabismus surgery is not only to correct eye position and improve appearance, but more importantly to establish binocular vision function. The best time for surgery is before 6 to 7 years old. Binocular vision training is performed after surgery to enhance and maintain stable stereoscopic vision function.

What causes strabismus?

Congenital abnormalities: caused by abnormal anatomical position or development of the extraocular muscles, or paralysis of the nerves that control the muscles. In medicine, strabismus that occurs within 6 months of birth is called congenital strabismus. In addition, there are also genetic factors. Strabismus is not inherited by all members of the family. This defect is often indirectly passed on to the next generation of children.

Generally, strabismus that occurs within 6 months after birth is called congenital strabismus. It does not have the basic conditions for establishing binocular vision and has the greatest harm to the development of visual function.

Incomplete development of visual function: binocular single vision function has not yet matured, and the extraocular muscles cannot be well coordinated. Usually, the peak period for strabismus in children is before the age of 5.

Immature development of the refractive system: Most children are farsighted. Due to their strong ability to accommodate, excessive accommodation will inevitably cause excessive convergence of the two eyes, which can easily lead to esotropia.

Dysregulation of the eye movement center: If convergence is too strong or abduction is insufficient, or both exist at the same time, esotropia will occur; conversely, if abduction is too strong, convergence is insufficient, or both exist at the same time, exotropia will occur.

Causes of strabismus: Strabismus often occurs after fever, cold, and surgical trauma. Fright, emotional tension or excessive mental stress can also induce strabismus.

Regardless of the cause, you must go to a regular ophthalmology hospital in time to ensure the effectiveness of strabismus treatment.

At present, strabismus is quite common, and it is a particularly serious eye disease among children. The occurrence of this disease will cause abnormalities in children's eyes and bring them serious harm. There are many factors that can induce strabismus.
