摘　　要：近视的高患病率已成为全球关注的问题,眼球过度扩张引起的机械拉伸,可导致多种眼底并发症以及血管系统的损伤。然而,微血管的异常变化更加隐匿微妙,容易被忽视。因此更有赖于影像技术的创新和发展,相干光层析血管成像术(OCTA)是一种新的非侵入性成像技术,可快速、逐层获取视网膜和脉络膜微血管系统图像。本文对既往近视眼底血流灌注改变的研究结果进行综述,以期为近视防控和深入了解近视眼发病机制提供新的方向。The high prevalence of myopia has become a global concern.Mechanical stretching caused by excessive eyeball elongation leads to various anatomical changes in the fundus and vascular abnormalities,which tend to be subtle and easily overlooked.Therefore,it is more dependent on innovation and development of imaging technology.Optical co⁃herence tomography angiography(OCTA)is a new non-invasive imaging technology which can quickly obtain the retinal and choroidal microvascular images layer by layer.This review summarises previous findings on myopia blood perfusion,so as to provide a new direction for the prevention and control of myopia and understanding the pathogenesis of myopia.
