Abstract: 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 lead to blindness., General 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. High myopia has obvious genetic factors, and it is autosomal recessive inheritance in domestic investigation., 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. The main complications are: 1. Flying mosquito disease: high myopia can produce real vitreous degeneration or liquefaction, causing obvious flying mosquito disease. 2. Conscious of the light, sparks, flashes or shadows floating in front of you., 2. Posterior scleral staphyloma: it is mainly manifested by the backward expansion of the posterior pole of the eye, which is the degeneration and atrophy of the nerve and the retina around the macula, and the decline of corrected visual acuity. The higher the degree of myopia, the higher the incidence., 4. Cataract: high myopia has cataract earlier than normal people, and most of them are core cataract. The difficulty of cataract surgery is often increased due to the relaxation of suspensory ligament, and the good or poor postoperative visual recovery is related to the degree of fundus retinopathy., 5. glaucoma: the incidence rate of open angle glaucoma is higher than normal people 6 to 8 times higher than that of normal people. However, glaucoma is often obscured by symptoms of high myopia due to its clinical symptoms. It is also common for high myopia to have cortical opacity at the posterior pole of crystalline body, and the dark adaptation time is relatively prolonged because the pathological changes of pigment epithelial cells in high myopia affect the reaction process of photochemical changes of visual cells., Because there are many complications of high myopia and can seriously affect visual function, patients with immediate dark shadow or decreased vision should pay great attention to it. It is suggested that patients with high myopia should go to a specialized hospital regularly to check the fundus and intraocular pressure, so as to facilitate early detection, early diagnosis and early treatment.,
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. High myopia has obvious genetic factors, which is autosomal recessive inheritance in China.
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. The main complications are:
1. Flying mosquito disease: high myopia can produce real vitreous degeneration or liquefaction, resulting in obvious flying mosquito disease. Consciously float the light, spark, flash or shadow in front of you.
2. Posterior scleral staphyloma: it is mainly characterized by the backward expansion of the posterior pole of the eye, the degeneration and atrophy of the nerve and the retina around the macula, and the decline of corrected visual acuity. The higher the degree of myopia, the higher the incidence.
4. Cataract: cataract occurs earlier in high myopia than in normal people, and most of them are core cataract. Often due to the relaxation of suspensory ligament and other reasons, the difficulty of cataract surgery will also increase, and the good and poor postoperative visual acuity recovery is related to the degree of fundus retinopathy.
5. glaucoma: the incidence rate of open angle glaucoma in high myopia is 6 to 8 times higher than that in normal persons. However, due to the clinical symptoms of glaucoma are not obvious, the visual function decline is often concealed by the symptoms of high myopia, and is easily overlooked. High myopia with posterior pole cortical opacity of crystalline body is also common, and the dark adaptation time is relatively prolonged because the pathological changes of pigment epithelial cells in patients with high myopia affect the reaction process of photochemical changes of visual cells.
and
patients with high myopia have more complications and can seriously affect visual function, so they should pay great attention to patients with dark shadow or decreased vision. It is suggested that patients with high myopia should go to a specialized hospital regularly to check the fundus and intraocular pressure, so as to facilitate early detection, early diagnosis and early treatment.
