Over the years, strabismus is a disease that has plagued many children, which has left parents at their wits’ end. Ophthalmologists point out that due to children’s incorrect eye habits, it is likely to induce strabismus and other eye problems to appear. Let’s take a look together. The common causes of strabismus are: 1, refractive error this child is born with high hyperopia, astigmatism, a few have high myopia, the refractive error of both eyes are similar or equal, the vision of both eyes are often similar or equal. If these children do not wear proper glasses, they can see the outside world like a camera without a good focus, always blurred, so that the impulse from the eye to the brain is weaker than the normal eye, so that the neural pathway from the eye to the visual center of the cerebral cortex is poorly developed, resulting in strabismus. This kind of strabismus is called refractive strabismus. When two eyes look at an object at the same time, the impulses from each eye to the brain are different, forming two clear and unequal objects in the brain’s visual cortex, and the brain cannot fuse them into one. In this way, the visual center actively inhibits the blurred image and only responds to the clear image, and over time, the eye with the deeper degree forms a strabismus, which is a refractive strabismus. 3. Strabismus is a common cause of strabismus. This child has strabismus or has had strabismus. When a strabismic child looks at an object with one eye, such as a table, the image of the table falls in one part of the eye, while the other eye looks at the table, the image of the table falls in another part of the eye, and the impulses from different parts of the eye to the brain respond to two images, which forms diplopia. On the other hand, the image next to the table falls to the macular area of the strabismus eye, so that this image and the image of the table in the brain of the other eye overlap together, creating a visual disorder, due to diplopia and visual disorder, the child feels extremely uncomfortable, so the cerebral cortex actively inhibits the impulses coming from the strabismus eye, and the vision of the strabismus eye decreases to become strabismus. 4, Formal deprivation during birth for some reasons, such as congenital cataract, congenital ptosis or inappropriate masking affects the light stimulus entering the eye, so that the eye cannot produce normal impulses, and there is no normal impulse transmission to the visual center, so that the development of the pathway from the eye to the visual center is affected, resulting in strabismus. 5, congenital strabismus This is a rare kind of strabismus, meaning that it is born with unclear reasons, some people believe that it is related to the hemorrhage of the fundus and the visual pathway during the neonatal period, and some are accompanied by tiny congenital nystagmus. Through the introduction of the above content, you should have an understanding of the causes of strabismus, the incidence of this disease is increasingly high, as parents, must take a serious look, if your health appears the symptoms of the disease, do not delay the diagnosis, should go to a regular hospital in a timely manner, so as not to miss a good opportunity for treatment.
