光学相干断层扫描血管成像在眼科的应用进展

Application of optical coherence tomography angiography in ophthalmology

摘要:

光学相干断层扫描血管成像(OCTA)是近年逐渐兴起的一种眼科非入侵式影像学检查方法，它是在光学相干断层扫描(OCT)的基础上逐渐发展起来并逐步应用于临床。OCTA通过扫描血管内流动的红细胞显示出眼底血流密度与眼底组织结构形态，在眼科相关疾病(尤其是眼底病变)的诊治及疗效评估方面具有很高的价值。OCTA具有高分辨率、易操作、快速扫描、三维成像等优势，现已被应用于眼科疾病(脉络膜新生血管、糖尿病视网膜病变、角膜和虹膜相关疾病、弱视、青光眼等)的评估和诊断。本文就OCTA技术在眼科疾病中的应用进行综述。

Abstract:

Optical coherence tomography angiography(OCTA)is a new noninvasive imaging method in ophthalmology. Based on optical coherence tomography(OCT), it has been gradually developed and applied in clinical practice. By scanning the red blood cells, OCTA can display the blood flow density and the structure and morphology of the fundus tissue, which has a high value in the diagnosis, treatment and efficacy of ophthalmological diseases(especially fundus lesions). With the advantages of high resolution, easy operation, rapid scanning and 3D imaging, OCTA has been applied in the evaluation and diagnosis of ophthalmic diseases(such as choroidal neovascularization, diabetic retinopathy, corneal and iris-related diseases, amblyopia, glaucoma etc.). This review is about the application of OCTA in ophthalmic diseases.
