Optical Coherence Tomography Angiography in Retinal Disorders

1 Abstract Optical coherence tomography angiography (OCTA) is a new non-invasive imaging technique that employs motion contrast imaging. It generates high-resolution volumetric blood flow information through angiographic images. Fluorescein and indocyanine green angiography are still the gold standard angiographic procedures but OCTA is slowly becoming an essential clinical investigation since the past few years. This article will cover the principle and clinical applications of OCTA.
