Manual Selection
Should you decide that the current scan does not have the best signal strength or that it
was taken in a position away from the center and, therefore, would not be a good match
you can manually choose a different scan using the manual selection process.
This option is also available in
• Advanced RPE Analysis
• Ganglion Cell Analysis
• ONH and RNFL Analysis
• Panomap
• Single Eye Summary
• OCT Angiography Change Analysis
How to select a scan manually:
1. At the top of the analysis screen, select the scan date and the scan you wish to use as the
more current scan (the scan information that appears on the right side of the screen).
2. Select Macular Change Analysis – Manual Selection from the far right column.
3. A list of eligible scans will appear in a dialog box (see
Figure 8-8 ).
4. Click the scan you wish to include in the analysis. A green checkmark will appear next
to the selected scan.
5. Click Next to proceed. The window will collapse and the scan you chose will appear as
the scan on the left–hand side of the screen.
NOTE: You may not choose two scans from different visits from the manual selection
window. You may only select one scan in this way to use as the earlier of the two scans.
