Advances in the application of optical coherence tomography angiography in the diagnosis of common fundus diseases

Abstract

Optical coherence tomography angiography (OCTA) is a new noninvasive fundus angiography technique that has been widely used in recent years, and compared with traditional optical coherence tomography, OCTA has a higher resolution and a faster scanning speed. Compared with fundus fluorescein angiography and indocyanine green angiography, OCTA has its own advantages in the diagnosis and treatment of various fundus diseases, such as no need for the injection of contrast agent, a short time for examination, and clear display of the three-dimensional structure of retina and choroid. Although OCTA cannot replace fundus fluorescein angiography in clinical practice at present, it can still be used as an important auxiliary examination in the diagnosis of fundus diseases. Fer this reason, our article reviews the advances in the application of OCTA in the diagnosis of common fundus diseases such as senile macular degeneration, retinal vein occlusion, diabetic retinopathy, and central serous chorioretinopathy.
