High myopia is common in the Asian population,with an incidence of about 4％.Most of them are axial myopia,and the posterior pole of the eyeball is elongated in the anterior and posterior axis.Axial length can cause changes in the retinal vascular system,such as narrowing of blood vessels,reduction of blood flow velocity,loss of capillaries,and choroidal neovascularization due to weak areas of the retina.Therefore,its effect on blood flow in the macular area and optic disc area should be considered in the diagnosis and treatment.Optical coherence tomography angiography can display the vascular morphology of the retina and choroid in layers,which provides a basis for diagnosis and follow-up evaluation.This article reviews the application of this technology in high myopia,so as to provide ideas for diagnosis and treatment.
