The Importance of Good Clinical Workflow
Patient Good Practices
A session for collecting images typically takes several minutes for each eye. Aligning the
patient and optimizing the scan account for most of the session time. The patient may rest
between scans as needed.
Specific to Iris Imaging
• Center the iris image within the pupil, unless a slight offset is required for retina tilt or
to avoid opacity.
• Focus on the iris detail.
Specific to Fundus Imaging
• Ensure the focus is sharp and clear with good visibility of the branching blood vessels.
• Center the scan overlay on the fovea for macular scans and on the optic nerve head
for optic disc scans.
• Ensure uniform illumination without dark corners.
• Eliminate or reduce artifacts that may cast shadows on the OCT scans.
• Attempt to move floaters away from the region of interest by asking the research
subject to look up, down, and from side to side.
• Minimize corneal opacities by realigning the pupil.
Daily Tasks
Start of Day
Each day that the CIRRUS HD-OCT system is to be used the following steps must be
followed:
1. Start the CIRRUS HD-OCT instrument
2. Wait for the system check to complete. If the system check passes with a non–critical
error, such as inadequate hard drive or network archive space, click Continue, and
then log on to the application. Scanning can proceed with inadequate local storage
space, as long as the scans can be archived elsewhere when the system is shut down.
NOTE: Login to the software. You must be assigned an account by the System
Administrator to use the software
NOTE: You may need to archive scans before acquiring new scans. If archive storage is
inadequate, you can acquire new scans but will be prompted to archive all unarchived
scans when shutting down the system. Or if a Database, Installation Files, or Instrument
failure occurs, you will not be able to use the instrument. Contact your Zeiss representative.
