OCTA在近视眼底血流量化的应用
|
Abstract:
近视的发展趋势逐年上升，成为全球的第二大致盲疾病。OCTA是近15年来新兴的技术，具有无创的特点，可以量化血流参数，使视网膜、脉络膜变得可视化，通过具体的数值方式来表现近视病人脉络膜血流和厚度的变化。本文综述了近年来OCTA在近视、高度近视眼后段成像及量化的研究进展，并讨论了这些发现的临床意义，为近视防控效果的评估提供了新的参考指标。
The prevalence of myopia has been increasing annually, making it the second leading cause of blindness worldwide. Optical Coherence Tomography Angiography (OCTA) is a relatively new technology that has emerged over the past 15 years. It is non-invasive and capable of quantifying blood flow parameters, making the retina and choroid visible. This allows for the representation of changes in choroidal blood flow in myopic patients through specific numerical methods. This article reviews recent advancements in OCTA imaging and quantification of the posterior segment in myopia and high myopia, discusses the clinical significance of these findings, and provides new reference indicators for evaluating the effectiveness of myopia prevention and control.
