光相干断层扫描血管成像在青光眼临床中的应用进展

Advance in the Clinical Application of Optical Coherence Tomography Angiography in Glaucoma

光相干断层扫描血管成像(optical coherence tomography angiography, OCTA)是近年来新兴的血管成像技术,作为一种无创性、高效的检查工具,它能根据不同层次显示视网膜、脉络膜的血管密度并对其进行量化。目前认为眼部循环的改变与青光眼的病情进展密切相关,利用OCTA获得的视网膜血管密度与结构、功能参数有着密切的关系,结合不同检查结果可为青光眼的诊治及评估病情严重程度提供可靠参考。

Optical coherence tomography angiography (OCTA) is a new technique of vascular imaging. As a non-invasive and efficient diagnostic tool, OCTA can display and quantify the vascular density of retina and choroid according to different levels. At present, it is believed that the changes of ocular circulation are closely related to the progression of glaucoma, and the retinal vascular density obtained by OCTA is closely related to the structure and function parameters. Combining different examination results can provide reliable reference for diagnosis and treatment of glaucoma and assessment of severity of the disease.
