Abstract:
Optical coherence tomography angiography (OCTA) obtains information of retinal and choroidal blood flow by processing the difference between repeated scan of the same voxel.OCTA can be used in fundus diseases because of noninvasive,three-dimensional and high resolution aquisition.OCTA is able to detect the alteration of blood flow in fundus diseases,especially in imaging the retinal and choriocapillary blood flow in normal fundus,age-related macular degeneration (AMD),diabetic retinopathy (DR),retinal vascular occlusion,etc.In this paper,the basic principle of OCTA and its applications in normal eyes,AMD and choroid neovascularization,DR,idiopathic parafoveal capillaries expansion of type 2,retinal vascular obstruction,central serous chorioretinopathy and polypoidal choroidal vasculopathy diagnosis are reviewed.
