NFL+GCL+IPL Analysis/GCL+IPL Analysis
The NFL+GCL+IPL and GCL+IPL thicknesses are analyzed on the basis of the captured
OCT image of the posterior part of the retina including the macula and optic disc in the
[Glaucoma 3D] mode.
The analysis results are shown, for example, as a map relating to the NFL+GCL+IPL
or GCL+IPL thickness and NFL+GCL+IPL or GCL+IPL grid indicating the superior and
inferior regions or symmetry of the right and left eyes.
These analysis results can be shown on the [Both Eyes], [Progression], and [Combined]
tab screens.
For details on the color patterns of NDB, see "NFL+GCL+IPL Analysis/GCL+IPL
Analysis/Optic Disc Analysis/Wide 3D Scan Analysis" (see page 154).
The following describes an example of how to perform NFL+GCL+IPL analysis.
To perform GCL+IPL analysis, right-click either SLO image/NFL+GCL+IPL grid, or
NFL+GCL+IPL Deviation map, or NFL+GCL+IPL Significance map, and select the
[GCL+IPL Analysis] from the menu.

The map to overlay on the SLO image can be selected from the list box. Values
corresponding to the map are shown on three types of grids.
• [NFL+GCL+IPL Thickness]: Thickness of NFL+GCL+IPL
• [NFL+GCL+IPL Difference (S - I)]: Difference between thicknesses of superior and
inferior regions at NFL+GCL+IPL
• [NFL+GCL+IPL Difference (R - L)]: Difference among thicknesses of NFL+GCL+IPL on
right and left eyes
• [SLO Image]: Image overlay disabled
* The area to calculate NFL+GCL+IPL thickness has been modified from the circle 10
mm in diameter to the area except the optic disc since the version 3.0.
