Nailfold capillaroscopy with a commercially available optical coherence tomography angiography for ophthalmic use

Optical Coherence Tomography (OCT) has had a revolutionary impact in evaluation of anatomical structures of the eye and became an important part of everyday clinical practice and research14 Technological advances have enhanced various aspects of OCT images including scanning speed, resolution and measurement of vascular flow.9 Optical Coherence Tomography Angiography (OCTA) is an imaging modality that enables blood vessels to be visualised via motion contrast imaging of red blood cells moving across sequential B scans at a given cross-section.6 Originally designed for the retina, OCTA is also being established as a useful non-invasive tool in imaging cornea and anterior segment of the eye.15
