Optical coherence tomography angiography (OCTA) is an innovative technique based on OCT, enabling the visualization of vessels in the various chorio-retinal layers in three dimensions without dye injection. It enables identification of the various retinal vascular plexi. This technique provides a new semiological analysis, with a better understanding of chorio-retinal vascular architecture, but it has certain limitations, as it is a static test sensitive to various artifacts linked to movement or changes in chorio-retinal architecture. OCTA is currently promising for the diagnosis of various non-inflammatory pathologies, but remains insufficient for therapeutic decision-making, and must be compared with data from older multimodal imaging techniques.
