Abstract: some high myopia will be complicated with simple glaucoma. The intraocular pressure is often not high, and the visual acuity gradually decreases. It is often mistaken for myopia, resulting in misdiagnosis. In case of such patients, the examination of visual field and fundus should be emphasized in order to strive for early diagnosis, early treatment and save vision., There are signs of vision loss and perceptual allergy symptoms: while eye fatigue occurs, many people are also accompanied by eye burning, itching, dryness and swelling pain. In severe cases, the pain spreads to the deep orbit, even causes migraine, and can also cause pain in the pillow, neck, shoulder and back. This is caused by fatigue perceptual allergy of sensory nerves in the eyes., Eye fatigue symptoms: reading for a long time, feel the handwriting overlap or serial. Look at the object in front. It’s ambiguous and unstable. These are the manifestations of ciliary muscle regulation failure caused by eye fatigue. In addition, some children and adolescents will have recurrent wheat granuloma and blepharitis, all indicating that the “prelude” of myopia has been played., Symptoms of general nervous disorders: some children with good grades will be bored with learning, become irritable and their academic performance will decline. Sleepy and sweaty at night, the body is easy to be tired, and has symptoms such as dizziness and loss of appetite. These are the manifestations of central and autonomic nerve disorders caused by eye fatigue, and are also the signals of impending myopia., If you get myopia, you must prevent complications. Cataract: it is manifested as brownish black nuclear cataract. If you remove the turbid lens in time or implant the intraocular lens at the same time, you can often remove the glasses at the same time to improve the far vision, but there is a risk of postoperative retinal detachment., Glaucoma: some high myopia will be complicated with simple glaucoma. The intraocular pressure is often not high, and the visual acuity gradually decreases. It is often mistaken for myopia, resulting in misdiagnosis. In case of such patients, the examination of visual field and fundus should be emphasized in order to strive for early diagnosis, early treatment and save vision.,
vision loss is an omen of
and
perceptual allergy symptoms: while eye fatigue occurs, many people are also accompanied by eye burning, itching, dryness and swelling pain. In severe cases, the pain spreads to the deep orbit, even causes migraine, and can also cause pain in the occipital, neck, shoulder and back, which is caused by fatigue perceptual allergy of sensory nerves in the eyes.
eye fatigue symptoms: reading for a long time, feeling the handwriting overlapping or serial. Look at the object in front. It’s ambiguous and unstable. These are the manifestations of ciliary muscle regulation failure caused by eye fatigue. In addition, some teenagers and children will repeatedly have wheat granuloma and blepharitis, which all show that the “prelude” of myopia has been played.
symptoms of systemic nervous disorders: some children with good grades will be bored with learning, become irritable and their academic performance will decline. Sleepy and sweaty at night, the body is easy to be tired, and has symptoms such as dizziness and loss of appetite. These are the manifestations of central and autonomic nerve disorders caused by eye fatigue, and they are also the signals of myopia.

have myopia and must prevent complications.
and
cataracts: they are brown black nuclear cataracts. If turbid lenses are removed in time or intraocular lenses are implanted at the same time, glasses can be removed at the same time to improve hyperopia, but there is a risk of postoperative retinal detachment.
glaucoma: some high myopia will be complicated with simple glaucoma. The intraocular pressure is often not high, and the visual acuity gradually decreases. It is often mistaken for myopia, resulting in misdiagnosis. In case of such patients, we should emphasize the examination of visual field and fundus, so as to strive for early diagnosis, early treatment and save vision.
macular hemorrhage and macular degeneration: it is more common in high myopia patients above middle age. Sometimes the latter is the result of the former development, and the incidence rate of the two is 45%. This disease has obvious damage to central vision and can not be corrected.
and
retinal holes (including macular holes): in addition to the macular part, they often occur in the equatorial part or peripheral part of the fundus, mostly horseshoe shaped or circular holes. On this basis, it further developed into retinal detachment. According to statistics, myopia accounts for more than 80% of the incidence of retinal detachment. If it is not treated in time (surgery or laser), it can cause irreversible permanent blindness.
vitreous lesions: almost all patients with myopia have different degrees of vitreous opacity in the middle and late stage. In severe cases, it can change in strip, block, network or membrane, and some have vitreous liquefaction, concentration or detachment. These lesions are the hotbed of retinal detachment, because the denatured vitreous organic cord can adhere to the retina and other parts, mechanically tear off a piece of tissue, cause a hole, and then retinal detachment.
true and false myopia should distinguish
the so-called false myopia is a fatigue state before true myopia. If this state can not be relieved in time, the organic changes in the eyes will form true myopia. Mydriatic optometry is needed to judge true and false myopia. The purpose of mydriasis is to relieve eye fatigue and relax the tense muscles, so that the tested diopter is accurate.
if the naked eye vision can reach 1 after mydriasis. 0, that is “pseudomyopia”, which can be cured in a short time. For example, the use of drugs, acupuncture, ear embedding needles and physiotherapy instruments can relax tense muscles, relieve fatigue and restore vision to normal. If you don’t want treatment, as long as you let your eyes look into the distance and pay attention to rest, your eyesight may also recover.
if the naked eye vision is lower than 0 after mydriasis. 8. It is “true myopia”. Once true myopia is irreversible, it is an organic change of the eyeball. The front and rear axes of the eyeball become longer. External objects are imaged in front of the retina through the refractive system of the eye. There is no clear object image on the retina, of course, there will be no good vision. In addition to surgery, no method can shorten the eyeball and change the diopter, which is the reason why myopia is difficult to cure.
at present, all kinds of refractive surgery of eyes are the only method that can treat myopia and reduce diopter. For example, excimer laser keratectomy (PRK) and laser in situ keratomileusis (LASIK) are used to decompose some tissues and cells of the corneal anterior elastic layer and stromal layer under the control of computer
