Optical coherence tomography angiography (OCTA) is an imaging which can applied in ophthalmology to provide
detailed visualization of the perfusion of vascular networks in the eye. compared to previous state of the art dye-based imaging,
such as fluorescein angiography. OCTA is non-invasive, time efficient, and it allows for the examination of retinal vascular in
3D. These advantage of the technique combined with the good usability in commercial devices led to a quick adoption of the new
modality in the clinical routine.
