Overview2660021169012 Rev. A 2017-12 CIRRUS HD-OCT User Manual9-8The AngioPlex Metrix fields appearonly when the default Superficial (SRL) Preset or RadialPeripapillary Capillaries (RPC) for ONH Angiography Analysis is selected (see "CIRRUSOCT Angiography Presets" on page 9-4.These AngioPlex Metrix fields provide information regarding vessel density and the FovealAvascular Zone (FAZ) and are described fully in "Vessel Density and CapillaryPerfusion" on page 9-11.This option is not available for Montage Angio.Current View ReferencesFor the selected Preset (shown on the left), the location of upper and lower boundariesare indicated. The appearance of the Current View References for Angiography looks likethe example margin graphic on the top left. The appearance of the Current ViewReferences for Montage Angio and ONH Angiography looks like the example margingraphic on the bottom left.In addition, selecting the Remove Projections check box (Angiography only) will removeprojection artifacts, such as decorrelation tails, from the images. Once the check box isselected, it remains so until unchecked. For more information, refer to "CIRRUS OCTAngiography Acceptance Criteria" on page 7-7.OverlaysThe appearance of the Overlay for Angiography looks like the example margin graphic onthe left. The appearance of the Overlay for ONH Angiography looks like the examplemargin graphic on the next page.•Thickness Map: Overlay an image with a thickness map. You can choose to addthe thickness map to either the AngioPlex viewport (left), the Structure viewport(right), or both. The thickness map is a topographic representation of the totalretinal thickness (ILM to RPE). The surfaces of the ILM and RPE layers aresegmented in the same manner as CIRRUS HD-OCT structural images (forexample the Macular cube 512x128).•Fundus Image: Overlay both the AngioPlex image and the Structure image withthe Fundus Image.Slice Navigators: Overlays the blue (fast B-scans) and magenta (slow B-scans) on theimages. Turn them off by deselecting the option. Hovering over the icons provides a briefdescription of what the icon does, as shown on the following page.
