Current View References

For the selected Preset (shown on the left), the location of upper and lower boundaries
are indicated. The appearance of the Current View References for Angiography looks like

•Thickness Map: Overlay an image with a thickness map. You can choose to add
the thickness map to either the AngioPlex viewport (left), the Structure viewport
(right), or both. The thickness map is a topographic representation of the total
retinal thickness (ILM to RPE). The surfaces of the ILM and RPE layers are
segmented in the same manner as CIRRUS HD-OCT structural images (for
example the Macular cube 512x128).
•Fundus Image: Overlay both the AngioPlex image and the Structure image with
the Fundus Image.
Slice Navigators: Overlays the blue (fast B-scans) and magenta (slow B-scans) on the
images. Turn them off by deselecting the option. Hovering over the icons provides a brief
description of what the icon does, as shown on the following page.
