High myopia has a high genetic tendency, it not only shows in the excessive elongation of the axial length, but also lends to the formation and progression of various eye lesions, such as peripheral retinopathy, optic disc changes, posterior staphyloma, and myopic maculopathy, due to the mechanical stretching of the axial length to the ocular structure. In addition, high myopia increases the risk of several complications, such as glaucoma, cataract, and corneal disease. All these pathological changes will affect visual function and lead to irreversible vision impairment and blindness in the future. Therefore, it is important to pay attention to screening for optic disc abnormalities and posterior staphyloma, and regular monitor the changes of fundus, intraocular pressure, and lens. At the same time, high myopia has an impact on personal life such as study, psychology, sport, and work, and can reduce the quality of life as well as increase the cost of health care. The clinic should pay more attention to high myopia, prevent and control the development of high myopia from an early stage, in order to minimize its impact on ocular structure and visual function as well as its hazard to personal life and society.
