Description

<p>Optical coherence tomography angiography (OCTA) is a novel method that non-invasively visualizes retinal blood flow in three dimensions. OCTA has advantages over fluorescein angiography in that it can help to visualize the retinal capillaries in higher contrast. Computational advances and use of artificial intelligence have enabled the visualization of a wider field of view with higher image quality, which has facilitated in reducing the gap between fluorescein angiography and OCTA. While OCTA is a very useful imaging modality, there are some unique artifacts in OCTA imaging, which should be taken into consideration when interpreting OCTA images.</p>
