Is high myopia really passed on to the next generation? What complications should we worry about rather than heredity

I don't know when, there are more and more people wearing glasses around.

Especially for teenagers, with the popularity of electronic products, myopia is becoming more and more common. If you don't pay attention to eye health, the incidence of myopia increases year by year. If you don't adjust it in time, it is easy to cause high myopia.

Coupled with the pressure of study, teenagers' high myopia is further aggravated.

What on earth is high myopia?

In the clinical vision test standard, if the degree is more than 600 degrees, it can be called "high myopia".

However, this standard is often simple and rough, without considering the influence of astigmatism and whether there are lesions in the fundus.

Most people's myopia still belongs to axial myopia, which leads to the inaccuracy of light gathering on the fundus retina, resulting in unclear visual signals.

The clinical myopia is often affected by heredity and environment, and the genetic factor is high myopia.

Of course, myopia is not a simple genetic disease. It is often affected by many genes, so it can not be simply determined that the next generation of high myopia must also be high myopia and may be completely normal.

High myopia can also lead to these complications:

First, retinal detachment

A serious consequence of high myopia is retinal detachment.

When myopia occurs, the patient's eye growth and nutritional transport will be impaired. Over time, degeneration around the retina will occur.

After deformation, the retina will be very weak, which is prone to perforation. At the same time, coupled with the influence of factors such as increased activity, it will pull the retina and eventually lead to detachment.

Second, strabismus, amblyopia or cataract

To say strabismus and amblyopia, some people may not understand it.

One of the fundamental reasons for these results is high myopia, because in the state of high myopia, the eyes can not get enough nutrition supply, which will change the permeability of the lens, make the metabolism of the lens abnormal, and finally have the problem of not seeing clearly. This kind of performance is called cataract.

In addition, strabismus and amblyopia mainly refer to the large difference in the degree of myopia of both eyes, especially if the difference is more than 300 degrees. In the process of using the eyes, the force of the two eyes is uneven, and over time, it is easy to appear exophthalmos or amblyopia.

Third, glaucoma

High myopia brings a lot of nutrition to the human body, including glaucoma. This is because after suffering from high myopia, the structure of the filter curtain at the inner corner of the patient's room is abnormal, which will increase the resistance of aqueous humor outflow and promote the increase of intraocular pressure.

Normally, the vitreous should be colorless and transparent, but the eyeballs of people with high myopia gradually increase, but the vitreous has no change.

Over time, the vitreous cannot fill all the space in the eye, and eventually there will be liquefaction problems, causing vitreous turbidity, and eventually leading to glaucoma.

Fourth, macular degeneration

The predisposing cause of macular degeneration is the poor blood circulation of eyes in people with high myopia. The retina becomes ischemic for a long time. Over time, new vascular growth factors will grow in the retina.

The walls of these new blood vessels are particularly weak, but too violent actions will be stimulated and cause rupture and bleeding. First, macular hemorrhage will be formed, and then a large amount of blood will be absorbed. The new blood vessels will rupture again. Under the influence of repeated rupture and repair, they will form spots and eventually lead to macular degeneration.

Fifth, posterior scleral staphyloma

Relevant studies have found that the eyes of people with high myopia often extend backward, which makes the sclera of the posterior pole weak. Once the eye pressure increases, it will form posterior scleral staphyloma.

How to prevent these complications in patients with high myopia?

For patients with high myopia, the most important thing is to have regular ophthalmic examination, usually once every six months.

In particular, focus on the inspection of the fundus and thoroughly inspect the whole week's retina. If retinopathy can be found in time, it can be prevented by fundus laser photocoagulation, so as to effectively reduce retinal detachment.

In addition, it is worth mentioning that if the pupil dilation examination is carried out on the same day, it may be blurred for several hours. It is recommended not to drive or be accompanied by relatives.
