anywhere in the Iris Viewport centers the field of view of the camera over the click
point). A centering target overlays the video image for posterior segment scans. For
anterior segment scans, a graphical scan pattern appears to show the alignment scan
pattern position, size, shape, and orientation (see
Figure 6-19 above). It remains in
the center of the image and illustrates the path of the scan beam.

Figure 6-13 , depending on the scan type). The Fundus Viewport, is not available for
Anterior Segment scans)

14.If you want to compare the current scan to a previous scan of the same patient, select
the prior scan option (just above the Fundus image) and the Repeat Scan dialog
appears.
