Figure C-3 illustrates how the age coefficient varies with A-scan number for a
representative scan line. The y-axis is the Age Regression Coefficient in micrometers per
year (μm/yr)
and the x-axis is the A-scan number (1 through 128).

Figure C-4 illustrates the relationship between Total Macular Volume (mm3) and age, as
observed in the st
udy population.

Conclusion
The Macula Normative Database and RNFL Normative Database were based upon Stratus
OCT retinal scans collected from subjects whom, per protocol, were deemed representative
of a normal population. The Normative Databases establish reference values for specific
Stratus OCT retinal scans which the physician can use to compare individual patient
measurements to those acquired in a normal population.
