Analysis view of optical coherence tomography angiography.

<p><i>Blue box</i>: Scan size is 4.50 x 4.50 mm and Ring Width on angioflow view is 0.75 mm (750μm). The signal strength index is “75”. Measurement mode is “density”. Reference line is “RPC (radial peripapillary capillaries)”. <i>White line</i> on angioflow view; Sectorial division of peripapillary region including nasal, inferonasal, inferotemporal, superotemporal, superonasal, and temporal regions was performed using Garway-Heath regionalization. The measured vessel densities of each region are presented in the right chart (green box) as %. <i>Scattered red dots</i> on B-scan view(left) indicates the detection of blood movement (angioflow). On right B-scan view, <i>red line</i> indicates internal limiting membrane while <i>yellow line</i> indicates RNFL posterior boundary using standard OCT-A software (version 2015.1.0.90). Red line to yellow line is the RPC layer.
