OCT Angiography Change - Manual Selection
Should you decide that the current scan does not show the best characteristics for a OCT
Angiography comparison, you can manually choose a different scan using the manual
selection process:
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 Angiography Change Analysis – Manual Selection from the far right column.
3. A list of eligible scans will appear in a dialog box (see
Figure 9-10 ).
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 only select one scan in this way to use as the earlier of the two scans.
