Long term high myopia may cause ocular complications

Abstract: macula is a yellow cell rich in lutein at 0.35cm below the temporal side of the optic disc. The depression in the center of the macula is called the central depression, which is the place where the human eye has the sharpest vision.

the onset age of myopia in China is advancing. The direct consequence of the aging of myopia is the extension of the course of myopia in Chinese myopia patients.

under the influence of prolonging the course of myopia, The distribution of people’s myopia will become more and more high myopia (generally refers to myopia above 500 degrees in the international community), resulting in more obvious ocular manifestations such as leopard shaped fundus and optic disc atrophy arc. In addition, long-term high myopia may also lead to a variety of fundus diseases, such as maculopathy, retinal hole, retinal detachment, etc., and even permanent visual function damage.

According to the data, the macula is a yellow cell rich in lutein at 0.35cm below the temporal side of the optic disc. The depression in the center of the macula is called the central depression, which is the place where the human eye has the sharpest vision. If a person has long-term (≥ 10 years) high myopia, the possibility of macular disease is significantly higher than that of ordinary people.

If a person has a macular hole, it will directly lead to a sharp decline in his eye vision. For example, if his corrected vision after wearing glasses can reach 1.0, his corrected vision may directly drop to 0.1 after the macular hole, and the visual damage is extremely serious. What’s more terrible is that most of the damage is irreversible. Even with surgical treatment, the postoperative recovery effect of some patients is not very ideal.

in addition, peripheral retinal degeneration, hole and retinal detachment are also possible fundus complications caused by long-term high myopia. The reason is that after long-term high myopia, the ocular axis is gradually elongated (the length of the ocular axis in normal people is 23 mm to 24 mm, and the distance of the ocular axis in high myopia can reach more than 26 mm). The elongated ocular axis can lead to degeneration and thinning of the peripheral retina, which makes the retina prone to crack or even fall off.
