3.2.8.1 The patient's view of OCT alignment

When in OCT capture mode the patient will see the following:
Alignment target
l
Tracking scan as a striped background
l
OCT scan pattern as a line or circle
l
To reduce the possibility of movement artifacts the patient should maintain focus on the center of the green
alignment target. Ask the patient to keep their head still in the standard alignment during OCT imaging.

Note
In some instances you may choose to ask the patient to align slightly off center. For example, when capturing
an ONH scan where the fovea to ONH distance is very wide, you may be unable to position the scan location
on the center of the optic nerve head. Ask the patient to look off center towards a suitable reference point on
the alignment target and recapture the opto map image.
For more information on the alignment targets, see Patient Alignment Guide on page 75 .
