Myopia 700 degrees belongs to high myopia, if there is no lesion in the fundus, 700 degrees is not too nervous, as long as correction can be. Simple things like wearing frame glasses or contact lenses, and adults can also choose corneal surgery or IOL implantation to correct it. If 700 degrees of myopia is accompanied by fundus pathology, it is not just myopia but pathological myopia. This type of patient’s vision cannot be completely normal even after correction, and the risk of retinal detachment, fissure, macular hemorrhage and formation of blood vessels is much higher compared to normal people. These are mainly due to the lengthening of the eye axis caused by excessive elongation, protrusion of the eyeball, and dilatation of the posterior pole of the eye, resulting in lesions of the fundus.
