Why does myopia have exophthalmos?

Abstract: the eyes can’t see distant objects clearly. Distant objects can’t be imaged in the retina, but form a focus in front of the retina, which is called myopia. Axial myopia causes eye deformation. The deeper the degree, the longer the eye axis, and the more prominent the eye will look.

As myopia, what are you most distressed about? Can’t see clearly, is it uncomfortable to wear glasses, or is it ugly to wear glasses… For many people, the most annoying thing should be that they are becoming more and more myopic, and their eyeballs are becoming more and more prominent. They have become what we call “goldfish eyes”,

Today I’ll talk to you about how to solve the problem of “goldfish eyes”.

Why does myopia have exophthalmos?

Why does myopia have exophthalmos?

The eyes can’t see distant objects clearly. Distant objects can’t be imaged in the retina, but form a focus in front of the retina, which is called myopia. Axial myopia causes eye deformation. The deeper the degree, the longer the eye axis, and the more prominent the eye will look.

Myopic people need to adjust their eyes in order to see objects clearly. If they adjust excessively for a long time, the ciliary muscle cannot stretch flexibly. Due to excessive adjustment, the extraocular muscle exerts pressure on the eyeball, the intraocular pressure increases, the intraocular tissue congests, the eyeball wall is compressed and gradually extends, and the anterior and posterior axis of the eyeball becomes longer, forming axial myopia. Due to the elongation of the anterior and posterior axis of the eyeball, Therefore, the eyeball is often prominent.

Eye protrusion are not caused by glasses.

In addition, the eye protrusion that causes myopia also has a visual effect, that is, glasses have a cosmetic effect. After wearing myopia glasses, the concave lens reduces the image of the eyeball, which looks smaller and used to it, forming a visual standard. When you take off your glasses and see the real eyeball, the change is obvious. You will inevitably feel that the eyes are deformed obviously. The greater the degree of glasses, the more obvious the feeling is.

Have no better treatment at present, but they can be improved. Please read on.

Myopia lenses can prevent and treat exophthalmos: because the eyeball of teenagers is still in the development stage, regulatory myopia is very easy to develop into axial myopia. Especially for high myopia, the anterior and posterior diameter of the eyeball is significantly prolonged, and the appearance is exophthalmos. If myopia is corrected normally at the beginning, this situation will be alleviated or even not occur.

Myopia surgery can improve the phenomenon of ocular process?

Myopia surgery can improve the phenomenon of ocular process?

Because the refractive power of the cornea accounts for 3 / 4 of the refractive system of the whole eye, as long as the curvature of the cornea is changed a little, the refractive system of the whole eye can be changed. Therefore, most of the current myopia operations are done on the cornea. Using excimer laser to cut corneal tissue is equivalent to making a lens on the cornea to change the corneal curvature, so as to change the degree of myopia to achieve the purpose of not wearing glasses.

The corneal thickness of our normal people is 500-570um. 15um corneal tissue is consumed for every 100 degrees of myopia, and our ocular axis is about 23mm (mm), so we can’t recover exophthalmos after myopia surgery. But if you don’t wear glasses for a long time, you will gradually get used to the phenomenon of exophthalmos, so some people will have this feeling. When you see someone who doesn’t have exophthalmos 2 years after myopia surgery.
