Eight complications caused by myopia

Abstract: myopia is more and more in China, and it is not a big problem in our view. In fact, its hidden harm is very great and will have a great impact on our life. So what are myopia complications? What are the complications of myopia?, Myopia is more and more in China, which is not a big problem in our view. In fact, its hidden harm is very great and will have a great impact on our life. Let’s talk about the complications of myopia. If you want to know, you can come in and have a look., What is myopia complication? Generally, myopia will not develop in adulthood, and those who continue to develop after the age of 25 are called progressive myopia. From now on, the diopter is more than 6.0d, so it is called high myopia. Because this kind of myopia has ocular pathological changes, it is also called pathological myopia or degenerative myopia. Almost all high myopia have axial growth and significant thinning of sclera at the posterior pole of the eye. The main pathological changes are atrophy and thinning of retina and choroid, which are aggravated year by year. As a result, there are many serious complications, most of which can cause blindness. It is the sixth blinding disease in China., What are the complications of myopia? First, posterior scleral staphyloma. The attack rate of posterior scleral staphyloma was 77.1%. The primary manifestations were posterior enlargement of the posterior pole of the eyeball, degeneration and atrophy of the optic nerve and perimacular retina, and decreased corrected visual acuity. The higher the degree of myopia, the higher the incidence of posterior scleral staphyloma., II. Retinal atrophy, degeneration, hemorrhage and hole.

what are myopia complications

generally myopia will not develop in adulthood, and those who continue to develop after the age of 25 are called progressive myopia. From now on, the diopter is more than 6.0d, so it is called high myopia. Because this kind of myopia has ocular pathological changes, it is also called pathological myopia or degenerative myopia. Almost all high myopia have axial growth and significant thinning of sclera at the posterior pole of the eye. The main pathological changes are atrophy and thinning of retina and choroid, which are aggravated year by year. Therefore, it produces many serious complications, most of which can cause blindness. It is the sixth blinding disease in China.

what are the complications of myopia

1. The incidence of posterior scleral staphyloma

was 77.1%. The primary manifestations were posterior enlargement of the posterior pole of the eyeball, degeneration and atrophy of the optic nerve and perimacular retina, and decreased corrected visual acuity. The higher the degree of myopia, the higher the incidence of posterior scleral staphyloma.

II. Retinal atrophy, degeneration, hemorrhage and hole

because of the factors such as longer ocular axis and posterior scleral staphyloma, patients with high myopia simply present retinal degeneration and hole, resulting in hemorrhage and retinal detachment, resulting in blindness.

3. Retinal detachment

retinal detachment is the most common complication of myopia. Due to axial elongation and intraocular dystrophy in myopia, cystic degeneration and lattice degeneration often occur around the retina. The retina in the degenerative area is very thin and prone to perforation. Some have been perforated and formed in sexual holes. In addition, vitreous liquefaction and increased mobility lead to retinal detachment. In retinal detachment, 70% are myopia.

IV. cataract

myopia has abnormal intraocular nutrition metabolism, which changes the capsular permeability of the lens, gradually produces turbidity due to lens nutritional disorder and metabolic disorder, and gradually decreases vision, resulting in concomitant cataract. This kind of cataract develops slowly, mainly core opacity and posterior capsule opacity.

v. the filter curtain structure at the atrial angle of glaucoma

myopia is abnormal, so the outflow resistance of aqueous humor in the eye is large, which is easy to cause the increase of intraocular pressure. According to statistics, 30% of high myopia have glaucoma, which will cause the gradual loss of vision.

VI. flying mosquito disease

high myopia can produce real vitreous degeneration or liquefaction, resulting in significant flying mosquito disease. Consciously float the light, Mars, light or shadow in front of you.

VII. The attack rate of subretinal rebirth vessels

is 5% – 40%. It is characterized by bleeding in the eyes, which is very nervous for most people and a threat to vision. If it occurs, it is best to see a doctor as soon as possible.

VIII. Strabismus and amblyopia

myopia can cause exotropia or exotropia. If the difference of myopia degree between two eyes is greater than 300 degrees, it is easy to cause exotropia and amblyopia with deep degree.
