OCT fundus image banding examples (A and B) below. As long as there are no saccades,
scans with OCT fundus images like these should be acceptable for analysis and the
operator is advised to save them.
Advanced RPE Analysis Acceptance Criteria
In order to detect sub–RPE illumination, CIRRUS looks for contrast in a slab created below
the RPE. If the retinal tissue is captured too low in the axial field of view of the scan, then
the algorithm will not produce a good result, because there will not be enough sub–RPE
pixels to create good contrast. See
below for an example of a scan with the
retina too low for acceptable detection of sub–RPE illumination. If you obtain an image
like this, it is advisable to retake the scan before running Advanced RPE Analysis (see
"Advanced RPE Analysis" on page 8-17
