statistically significant if the range of rates covered by the 95% confidence limits exclude
zero.
It may be more useful to note that if the 95% confidence bands include a rate consistent
with normal aging, the observed change may be due to normal aging process rather than
glaucomatous loss.

Normative Data Details Reports

There is measurement variability for the macula parameters which may impact the
normative database color coding. If the true value is near the limit of what the software
uses to determine the normative database color code, then it is possible that the color
code could vary from exam to exam. When at least one parameter is close to a normative
limit, a blue icon button displays. When your cursor hovers over this icon button, the
tooltip appears as shown below.

If you click the blue icon button, you can select Print Preview or Export to DICOM. A Print
Preview screen displays the Normative Data Details Report as shown below. The report can
be printed from the Print Preview screen.

Macula Thickness Normative Data Details Report

The Normative Data Details Report displays the parameters of the analysis in the units
measured and as a percentile from the normative database. In addition, the report displays
the result minus the reproducibility limit, as well as the result plus the reproducibility limit,
and their corresponding percentiles. Each of these measurements are presented with the
appropriate normative database color code.
This report provides the ability to see how close a particular measurement comes to a
normative limit cutoff by checking the actual percentile. In addition, the plus measurement
variability and the minus measurement variability values are also color–coded so the user
can determine if the original normative database designation would cross over to a
different color level when considering the measurement variability. Due to measurement
variability, it is possible that the normative data color coding may change on subsequent
visits without representing a change in the condition of the patient. For more information
on measurement variability, please see Appendix B.
