光学相干层析血管扫描在视网膜静脉阻塞中的应用

Application of optical coherence tomography angiography in retinal vein occlusion

视网膜静脉阻塞(RVO)是眼科临床常见的眼底视网膜血管性疾病。RVO属于视网膜血管性疾病,观察发病后视网膜血管尤其是毛细血管的变化对于视网膜静脉阻塞的治疗以及预后的观察评估有着重要的意义。一直以来,荧光素眼底血管造影(FA)是检查视网膜血管性疾病的金标准,但是FA是一项有创检查,存在有过敏等风险。近年来,光学相干层析扫描血管成像(OCTA)是一种快速、非侵入性的新型血流成像技术,不仅能够定性的分析眼部血管形态,更重要的是能够无创性定量测量眼部血管及血流灌注,同时还能对深部病变进行评估。对OCTA在视网膜静脉阻塞中的应用、优点及局限性进行综述。

Retinal vein occlusion (RVO) is a commonly encountered retinal vascular disease in the ophthalmology department. RVO is a retinal vascular disease. Observing the changes of the retinal blood vessels, especially the capillaries, is of great significance for the treatment of retinal vein occlusion and the observation and evaluation of its prognosis. Fluorescein angiography (FA) has long been the gold standard for the examination of retinal vascular diseases, but it is an invasive examination, allergies and may cause allergies and carries other risks. The recently emerging optical coherence tomography angiography (OCTA) is a rapid, non-invasive blood flow imaging technology. It can not only qualitatively analyze the shape of the eye's blood vessels, but more importantly, it can help to perform non-invasive quantitative measurement of the blood vessels and blood perfusion in the eye, as well as assessment of deep lesions. This article reviews the application, advantages, and limitations of OCTA in retinal vein occlusion. Retinal vein occlusion.
