The Anterior Chamber Angle measurements provided by CIRRUS HD-OCT are not intended
to be a substitute for gonioscopy, which is the current reference standard for evaluating the
anterior chamber angle configuration. For example, during gonioscopy, end users can view
the ACA through a mirror/prism under dynamic conditions, and can examine the angle
over the full extent. CIRRUS HD-OCT provides an optical image of the angle as represented
(and analyzed) by the software at a single location.
In Wide Angle-to-Angle Analysis
In addition to providing a wide view image of the anterior chamber, angle tools and
calipers are provided with the Wide Angle-to-Angle Analysis to allow angle measurement
as shown in
Figure 8-28

High Definition Images Analysis
For all raster scans, High Definition Images is the only available analysis.
When you select a high-definition raster scan from the Analysis screen scan list, the High
Definition Images analysis for that scan is automatically displayed.
The High Definition Images analysis screen displays the following:
• Signal strength, scan length, scan angle, line spacing, and image tools
• A fundus image with an overlay showing the location of the scan lines
• For multi-line scans, thumbnails of the scan line images
• A single larger image of the selected scan line for HD 1 Line 20x scans
