CIRRUS HD-OCT User Manual
When the prior scan is found, its scan setup parameters are used, and a Prior Scan link is
created (showing the eye, and exam date and time).
Auto Repeat can aid your workflow in the following situations:
• You perform only one type of scan per visit.
• You perform multiple scans and scan types but in different scan areas, for example
Macula Cube 512x128 followed by Optic Disc Cube 200x200.
• The patient is able to maintain head position between scans.
Auto Repeat may not be desirable for use in the following situations:
• You perform multiple scans using different scan types in the same scan area per visit,
for example: Macula Cube 512x128 followed by HD 5 Line Raster, or Macula Cube
512x128 followed by Macula Cube 200x200. In this instance, using settings from the
current visit is more efficient.
• The patient has difficulty or is unpredictable in maintaining head position. In this
instance, the repeat scan may be very different from the current position.
If you do not want the chinrest and ocular lens to move from the currently aligned position
when switching to another scan type, you can select the Prior Scan link to use previous
scan settings for any scan you wish to acquire.
Turn off Auto Repeat after the initial chinrest and focus adjustments are in place, or after
acquiring the first scan, and prior to choosing the second scan. This will ensure that the
settings used for the first scan will be maintained.
When you select a Prior Scan, the previously saved reference OCT fundus image is overlaid
in the scan pattern box over the live fundus image.
Before using FastTrac, open the Tools menu and make sure both the Auto Repeat and
Tracking features are checked.
FastTrac can be turned on and off as a global choice for all scans in the Tools menu.
