Viewing stereo images
Stereo Images are a pair of images of the same eye. Each image is taken with the patient aligned slightly off
center; with one image captured when the patient is aligned slightly to the left and the other when aligned
slightly to the right.
The viewing technique being used should be selected before the images are opened, see Setting User
Preferences on page 15. This ensures the images are displayed on the correct side of the screen for the
technique being used.
Caution
Stereo Images should not be used for diagnostic purposes.
1. Open the Stereo Images, see How to open stereo images on page 37.
2. If using a Stereo Overlay, you should manually register the images to ensure the optic disk and
macula positions match, see Registering Image Reference Points.
3. Using your preferred reviewing technique, review the images using a stereo viewer (stereograph)
or focus either beyond or in front of the two images, until you see the images as one.
Note
l
You will need to close and reopen the Stereo Images if you change the user setting options during
the review.
l
The Adjustment and Information panels are automatically hidden when Stereo Images are
displayed. You can display them if required, see Using the Adjustment and Information panels
on the facing page.
