Strabismus is a common type of eye disease, which can affect the overall beauty and bring about a variety of psychological problems. Strab vision can cause vision loss and affect life and work. How does strabismus cause? What are the causes of strabismus?
1, genetic
strabismus has a certain genetic tendency. If both parents have strabismus, the child's chance of inheriting it will reach more than 70%. But this does not mean that all strabismus can be inherited, it is just that common strabismus has multifactorial genetic characteristics.
2. Congenital paralysis strabismus
When birth or within one year of birth, it can become congenital paralysis strabismus. The main causes are congenital abnormalities or infantile diseases. In addition, if the delivery of forceps or the delivery time is too long, it may damage the baby's external muscles or surrounding tissues, causing extraocular muscle paralysis. In addition, strabismus may also induce strabismus during infancy, trauma, tumor bleeding or persistent fever.
3, myopia
If myopia people have completed the eyes to look at objects close to each other, half of the person with the frontal eye needs to be adjusted, but the collection and adjustment dysregulation will be caused. At this time, in order to overcome the imbalance, balance will be obtained by weakening the set, resulting in an outer slope. Over time, it will cause visual fatigue and form extrinsic .
4, hyperopic eyes
hyperopic eyes are prone to intrastril , which is closely related to internal oblique adjustment and collection. To maintain binocular monovision, the collection will be over and continuously adjusted, resulting in internal strabismus. The object of the hyperopic eye falls behind the retina and needs to be over-adjusted to allow the object to fall on the retina. At this time, it will overstimulate and adjust the assembly, causing internal strabismus for a long time.
5. Trauma of the craniocerebral
When the craniocerebral trauma is trauma, it will cause peripheral nerve paralysis, resulting in eye muscle dysfunction. Although the eyes can turn outward, movement in other directions is limited, the eyeball is obliquely positioned outside, the pupil is wide open and there is diplopia.
6. One eye has low vision
When one eye has low vision or blind vision, it will cause the eyes to perceptually fusion disorder to form strabismus, which is called perceptual strabismus.
Warm reminder
Strab vision can be used reasonably to correct the corrective glasses under the guidance of a doctor. You need to expand your pupils to see if there are any lesions in the fundus, and then choose appropriate glasses after determining the refractive index. You need to have an optometry every year. Can adjust the eye degree in time as the condition changes. If the vision difference between the two eyes is too large, it can cover the healthy eyes. This will allow the slanted eyes to see things that are mostly stimulated by light, which promotes retinal development. If strabismus is very serious, it needs to be treated through surgery. Before the age of 7, it is the best time to undergo surgery. It can adjust the strength of the external eye muscles and the position of the attachment point, improve the appearance, and establish binocular vision.
