Abstract: high myopia with posterior polar 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., General myopia will not develop in adulthood, and those who continue to develop after the age of 25 are called progressive myopia. In terms of diopter, Over 6.0d (600 degrees) is called high myopia. Almost all high myopia have eye axis 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 aggravate year by year. Therefore, many serious complications may occur, most of which can cause blindness. It is the sixth blinding disease in China. The main complications are:, Incidence rate of glaucoma in cataract, glaucoma and high myopia is 6 to 8 times higher than that in normal persons. However, due to the lack of obvious clinical symptoms of glaucoma, visual function is often concealed by symptoms of high myopia, and is easily overlooked. 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., Flying mosquito disease, high myopia can produce real vitreous degeneration or liquefaction, causing obvious flying mosquito disease. Conscious of the light, sparks, flashes or shadows floating in front of you., Posterior scleral staphyloma,
generally myopia will not develop in adulthood, and those who continue to develop after the age of 25 are called progressive myopia. In terms of diopter, Those with more than 6.0d (600 degrees) are called high myopia. Almost all high myopia have eye axis 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, many serious complications may occur, most of which can cause blindness. It is the sixth blinding disease in China.
The main complications are:
,
cataract, glaucoma
,
, high myopia incidence rate of open angle glaucoma is 6 to 8 times higher than that of ordinary people. But because of glaucoma clinical symptoms are not obvious, visual function decline is often covered by high myopia symptoms, easily overlooked.
and
are also common in high myopia with posterior polar cortical opacification of the amygdala, 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.
flying mosquito disease
high myopia can produce real vitreous degeneration or liquefaction, causing obvious flying mosquito disease. Consciously float the light, spark, flash or shadow in front of you.
posterior scleral staphyloma
is mainly manifested in 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.
retinal degeneration, hemorrhage, hole and detachment
due to the lengthening of the ocular axis, the thinning of the posterior half of the eyeball, the atrophy and degeneration of the retina and choroid, there are holes, leading to hemorrhage and retinal detachment of different ranges, resulting in visual loss. In addition, macular degeneration is also the biggest risk of high myopia, which shows visual deformation, vision decline, and eventually lead to blindness.
which operations can treat myopia
1. If unfortunately, the vision suddenly becomes very poor or things are distorted and deformed, it may be that the retina has been stripped. Go to a regular large hospital to find an ophthalmologist for diagnosis and treatment immediately.
2. Go to the ophthalmology department for fundus mydriasis examination at least every six months, If there are early lesions (such as cracks), laser treatment can be used first, so as to prevent deterioration into retinal detachment.
3. Patients should supplement an appropriate amount of vitamins A, C and e at ordinary times, and try to avoid ocular trauma and violent explosive movement.
Generally, the optic axis of patients is quite long, and it will be deepened due to acquired factors or congenital inheritance. Therefore, the incorrect eye use method must be corrected and eye repair surgery must be carried out in time to effectively prevent the further decline of vision. Myopia correction surgery is an excimer laser surgery carried out in many large hospitals. This surgery is more effective for patients with high myopia to improve their eyesight, but it is a corrective method. This excimer laser surgery has certain indications. When the degree is 600-1500, excimer laser treatment of high myopia is feasible, but whether this laser operation can be performed still needs preoperative examination, and the thickness of cornea is the key. If it exceeds 1500 degrees, laser treatment is very difficult. In this case, crystal implantation can be taken.
