Interactivity
For both the RNFL Thickness and Neuro–retinal Rim Thickness TSNIT graphs, as shown in
Figure A-10 , the user can toggle between data for both eyes together, or separately for
right eye or left eye. This is done by clicking the gray button in the upper left corner of the
Neuro–retinal Rim Thickness graph and RNFL Thickness graph, which will be labeled “OU”,
“OD”, or “OS” depending on what the user has chosen.

Ganglion Cell Normative Database: Diversified
The CIRRUS HD-OCT Ganglion Cell Normative Database was collected to provide normative
data for use with The Ganglion Cell Analysis module, and presents information on the
thickness of the ganglion cell plus inner plexiform layer.
Post–hoc analysis was performed on the Macular Cube 200x200 and Macular Cube
512x128 cube scans, originally acquired for Macular retinal thickness normative data, to
determine the typical distribution for Ganglion Cell Analysis parameters and the GCL + IPL
thickness map. This analysis compares the GCL + IPL thickness results to normal limits
derived from post–hoc analysis of scans used for the Macular normative database. An
example of the Ganglion Cell Analysis page with normal limits applied for the Ganglion
Cell Analysis parameters is shown below in
Figure A-11 .
