Is cross-eyed strabismus?

Many people are very concerned about some changes in their bodies in life. Some people always feel that they always see things in one direction when they walk. Others also seem to have problems with their eyes. After careful observation, they find that they have cross-eyes, which is a kind of strabismus. There are many types of strabismus. Patients can choose the appropriate method for treatment based on the factors and pathological changes.

strabismus

Name of eye disease. The pupils of one or both eyes are often tilted toward the middle. Commonly known as cross-eyed or cross-eyed.

Symptoms of esotropia

The main manifestation of esotropia is that the pupils in the middle of the eyes are naturally or artificially moved closer to the middle, looking like two chickens fighting, so it is also called cross-eyes or crossed eyes.

When a normal person looks at the same object with both eyes, images of the object are formed on the retinas of both eyes and overlap in the visual center of the brain to become a complete, three-dimensional single object. This function is called binocular single vision. However, infants and young children are easily affected by external factors during the process of developing binocular single vision, causing one eye to focus on a target while the other eye deviates and cannot look at the same target, thus resulting in strabismus.

Causes and pathology

The formation of strabismus is divided into congenital strabismus and acquired strabismus according to the age of onset. Strabismus that develops within six months after birth is called congenital strabismus. Strabismus is related to genetic factors. Investigations have found that some congenital strabismus is hereditary. Not only children have strabismus, but parents or grandparents also have the same strabismus. Studies have shown that strabismus is a multi-gene inheritance, so the incidence of the disease in the family is not very obvious.

Strabismus that occurs after six months of age is called acquired strabismus. This type of strabismus usually develops and worsens gradually. Esotropia is common in children with high hyperopia. Due to high hyperopia, both distant and near vision are not clear.

When it is difficult to see things close up, the eyes need to make height adjustments in order to see clearly. Height adjustments will produce over-convergence, thus causing esotropia. Myopic eyes often do not need to adjust when looking at close objects, which results in convergence insufficiency and often causes exotropia.

Some children have amblyopia in one eye and cannot focus with both eyes. Over time, the amblyopic eye develops exotropia due to long-term disuse. This situation is particularly likely to occur in children because the brain's fusion function is still relatively fragile and unstable, or has not yet reached perfection and consolidation, and amblyopia can cause fusion function disorders, resulting in strabismus. In clinical practice, if children have anisometropia or high refractive error, they cannot form binocular vision and have no fusion function, which will eventually lead to strabismus. This is a very common cause of strabismus.
