The color fundus images are automatically positioned.
CAUTION
The result of registration is as follows: Double-click an optional point on
the two tomogram display areas, the two fundus image display areas
and the upper right "Compare Window". The green line with a cross
mark appears. (Pin-point Registration™) Sometimes this green line
with a cross mark appears out of the 3D scan area (green frame).
There are two probable causes.
• On the two fundus image display areas, the fundus image is not
aligned with the "Overlay" image correctly.
• On "Compare Window", the two "Shadowgram" images are not
aligned with each other correctly.
To obtain the correct results, check the alignment on the two fundus
image display areas and on "Compare Window". If the images are not
aligned correctly, carry out "Reposition".
