RESUMO
High myopia is the main cause of visual impairment in the world. With the development of society, the myopia rate is increasing year by year. The development of high myopia is closely related to the progressive extension of the eye axis, and a series of fundus changes will inevitably occur with the extension of the eye axis, such as comus, lacquer cracks, choroidal neovascularization, macular choroidal atrophy, retinal detachment, posterior scleral staphyloma, etc. At present, characterized by younger age and high degree, myopia has become the main cause of blindness in China. This paper briefly summarizes the latest research on the morphological changes of the optic disc, macula, retina, choroid and sclera of high myopia, aiming to provide references for the development of intelligent prediction models, clinical diagnosis and further research on the treatment measures in combination with the fundus morphology of high myopia.
