Conclusion
The CIRRUS HD-OCT RNFL and macular thickness normative databases were created using
data from subjects that were deemed representative of a normal population. The CIRRUS
HD-OCT normative database for RNFL thickness established reference values for the Optic
Disc Cube 200x200 scan. The Macula normative database established reference values for
the Macular Cube 512x128 and Macular Cube 200x200 scans. The doctor can use these
normative databases to compare individual patient measurements to those acquired in a
normal population.
Optic Nerve Head Normative Database: Diversified
The CIRRUS HD-OCT Optic Nerve Head Normative Database was collected to provide
normative data for use with Optic Nerve Head (ONH) and RNFL OU Analysis module.
Post–hoc analysis was performed on the Optic Disc 200x200 cube scan, originally acquired
for RNFL normative data, to determine the typical distribution for Optic Nerve Head
parameters and the Neuroretinal Rim Profile. An example of the ONH parameters is shown
in
Figure A-7 . This addendum summarizes the data collection methodology and further
describes the analysis and characteristics of the normative limits for Optic Nerve Head
parameters.
