c. Turn their head slightly so that their nose is on the outside of the face pad. You should check
that the patient's head is vertical and has not been tilted.
5. After they are comfortable, ask the patient to move to the correct alignment position. The alignment
colors seen by the patient are also shown on the touch screen.
6. Adjust the alignment. The alignment target will change to green when the scan head is the correct
distance from the patient's eye. If the target turns red the scan head is too close. If the target turns
blue the scan head is too far away.
When aligning the patient the center of the cross hairs should be close to the center of the pupil
l
as possible.
In some instances you may choose to capture an image when the patient is aligned to the blue
l
or red target. If the patient has an
target is red. If the patient has very large pupils you may choose to capture when the target is
blue.
7. The x, y, and z alignment co-ordinates are shown. Ideally these should be as near to zero as practical,

2. Align the patient, see How to align the patient on the previous page.
3. Ask the patient to open both eyes wide, and to look at the center of the alignment target. Using the live
SLO image, center the cross hairs on the pupil until the target is aligned and turns green.
4. Capture the image either manually or using auto-capture.
Auto-capture: Auto-capture is enabled when

The system captures an image when the scan head is correctly aligned. You can press the
screen to manually capture the image.
Manual capture: Align the scan head into the correct position. Press the screen to capture the
l
image when the pupil is in the center of the cross hairs and the patient alignment target is
green.
