images, the identification of layers is different, so the CIRRUS HD-OCT is expected to
provide a thicker measurement than the Stratus OCT.

Because of this difference in segmentation strategy, there is a mean difference in the
retinal thickness found by each instrument. Furthermore, because the integrity of the layers
sought varies with pathology, the mean difference between instruments varies with
pathology, as can be seen in
. Even after the mean difference has been
accounted for, there is a residual difference that can be seen in the standard deviation of
the difference reported in the last column of
. Because of the residual
difference, it is better to compare scans between Stratus OCT and CIRRUS HD-OCT
qualitatively, looking for changes in retinal morphology, rather than making decisions
based on quantitative evaluation.
