Abstract: after myopia, due to the less use of adjustment and more use of collective function, the imbalance of adjustment and collective function is caused, and the internal rectus muscle is in an excessive tension state for a long time. Over time, the internal rectus muscle function is insufficient, and the collective function of both eyes is weakened accordingly, so it is very easy to cause exophoria or exotropia.
myopia is also called myopia, because this kind of eye can only see near but not far. At rest, the parallel light from infinite distance, after refraction of the refractive system of the eye, synthesizes the focus at the set of the retina, and forms an unclear image on the retina. The hyperopia is significantly reduced, but the near vision is still normal. Although myopia is a common ophthalmic disease, But often can not cause us to pay attention to this disease, many people think that myopia does not need treatment, this view is wrong!
1. Visual fatigue
due to unclear vision and enhanced eye regulation, eye muscles are in an excessive tension state for a long time, which is easy to cause eye fatigue. There may be eye swelling, eye pain, orbital pain, dizziness, nausea and other symptoms.
2. Cause strabismus. After myopia of
, due to the use of less regulation and more collective function when looking close, resulting in the imbalance of regulation and collective function, the internal rectus muscle is in an excessive tension state for a long time. Over time, the internal rectus muscle function is insufficient and the collective function of both eyes is weakened, so it is very easy to cause exophoria or exotropia.
3. Macular hemorrhage and degeneration
degenerative myopia due to fundus lesions, can cause macular hemorrhage, retinal and choroidal atrophy and degeneration, which seriously affect vision.
4. Retinal detachment
high myopia due to the elongation of the eye axis and the liquefaction and degeneration of the vitreous, the fiber cords in the vitreous can adhere to the retina and pull the retina. When the eyeball is impacted by external forces or trauma, it can cause retinal rupture and retinal detachment. Retinal detachment is the most serious complication of high myopia, Vision is extremely decreased. If not treated in time, it can lead to blindness.
5. Flying mosquito disease
“flying mosquito disease”: due to the liquefaction of the vitreous in the eye, the elasticity of the eyeball is reduced, which can produce floating objects in the vitreous, that is, “vitreous turbidity”, and black shadows such as dot, arachnoid and filamentous flutter in front of the eyes, commonly known as “flying mosquito disease”.
6. Will genetic
myopia be inherited. About 5% of myopic patients are related to heredity, usually more than 600 degrees. If both parents are highly myopic, the possibility of genetic offspring will be 90%. If one of the parents is highly myopic, the possibility of genetic offspring is 50%, but there are also incomplete manifestations.
