摘　　要：光学相干断层扫描血管成像(optical coherence tomography angiography,OCTA)是一种非接触、无创的、快速的血管造影技术,它通过检测红细胞在血管内的光学相干断层扫描(optical coherence tomography,OCT)信号的变化来提供血管影像。由于这项技术不需要注射血管造影剂,使得它比传统的眼科血管造影技术更安全。在前节疾病的检查中,OCTA不仅能够量化前节血管的范围和密度,还显示出良好的成像质量,为临床监测疾病的病程和对治疗的反应提供客观的评价。Optical coherence tomography angiography(OCTA)is a noncontact,noninvasive,and rapid angiography technique.It provides vascular images by detecting changes in the optical coherence tomography(OCT)signal of red blood cells in the blood vessel.Since this technique does not require injection of angiography,it is safer than traditional ophthalmic angiography.In the examination of anterior segment diseases,OCTA can not only quantify the range and density of anterior segment blood vessels,but also shows good imaging quality,providing an objective evaluation for clinical monitoring of the disease course and response to treatment.
