Abstract:
High myopia is a state of refractive error with myopia over -6.00D. High myopia is typically accompanied by multiple fundus lesions, thus making patients with high myopia suffer from varying degrees of impairment in visual function. As an emerging auxiliary way in ophthalmology, optical coherence tomography angiography(OCTA)can efficiently and non-invasively obtain microvascular stratified images of the retina and choroid and quantitatively analyze blood flow signals. Since the advent of OCTA, there have been numerous studies observing fundus changes in those with high myopia through OCTA. In this paper, some studies in which OCTA is applied to obtain retinal and choroidal thickness from patients with high myopia are reviewed, with a view to revealing the correlation between high myopia and the parameters such as retinal thickness, choroidal thickness, vessel density and the area of the foveal avascular zone and providing novel ideas to deeply investigate the mechanism of high myopia and delay the occurrence and development of high myopia.
