Abstract:

With the development of optical coherence tomography (optical coherence tomography angiography, OCTA), quantitative study of choriocapillaris (choriocapillaris, CC) has become a novel evaluation method. The occurrence and development of eye diseases, such as retina and choroid are closely related to the morphology and function of choroidal vessels, especially the change of choriocapillaris. The CC flow deficits parameters, such as density, area and number can be obtained after processing and quantitative analysising images of CC layer from OCTA, assess changes in choroid blood capillary perfusion, explore the pathogenesis of related diseases and provide certain help for disease diagnosis and intervention therapy. This paper reviews the clinical application and research progress of choroid capillary flow deficits.

Key words: choroid, choriocapillaris, tomography, optical coherence, choroid flow deficits, central serous chorioretinopathy, age-related macular degeneration
