Abstract
Optical coherence tomography angiography (OCTA) is an noninvasive, rapid and reproducible technology which can provide high resolution view of the vascular structures and quantifies the vessel densities in retina and choroid. Myopia can be divided into simple myopia and pathologic myopia. The mechanism of myopia is not clear while it is closely related to the vessel density. For simple myopia, OCTA can monitor the course and deepen the understanding of myopia by quantifying the vessel densities in each layers and sectors and the foveal avascular zone. For pathologic myopia, OCTA has an advantage of observing the choroidal neovascularization, chorioretinal atrophy and Zinn-Haller arterial circle which can contribute to the early diagnosis and management and follow-up to estimate the prognosis. However, there are several limitations of OCTA which need to be improved, including in the process of acquiring high-quality images, accurate layering and dynamic observation.
