Abstract

Optical coherence tomography angiography (OCTA) is an advanced noninvasive method of 3D imaging and quantitative analysis of the retinal and choroidal microvasculature. It allows detecting manifestation and progression of diabetic retinopathy, planning treatment and evaluating its results. OCTA expands our understanding of microvascular changes in retinal vascular plexuses in different stages of disease and deepens understanding of its pathogenesis. Keywords: optical coherence tomography angiography; fluorescein angiography; diabetic retinopathy; foveal avascular zone; retinal blood flow
