Better understanding retinal and choroidal vascular diseases with optical coherence tomography angiography / 中华眼底病杂志

ABSTRACT

Optical coherence tomography angiography (OCTA) is a new and non-invasive imaging technique that is able to detect blood flow signal in the retina and the choroid within seconds.OCTA is different from the traditional angiography methods.The major advantages of OCTA are that it can observe blood flow signal in different layers of the retina and the choroid without injecting any dye,provide blood flow information that traditional angiography cannot provide,and enrich pathophysiological knowledge of the retinal and choroidal vascular diseases.,which help us to make an accurate diagnosis and efficient evaluation of these diseases.However there is a large upgrade potential either on OCTA technique itself or on clinical application of OCTA.We need to fully understand the advantage and disadvantage,and differences of OCTA and traditional angiography.We also need to know how to interpret the result of OCTA.With that we could make a fast diagnosis in a non-invasive way and improve our knowledge of the retinal and choroidal vascular diseases.
