• On the right appear circular diagrams showing quadrant and clock-hour RNFL
thickness averages. Overall RNFL Average thickness appears at lower right.
• Click the Caliper ON ch
eckbox to measure distances between the cross-shaped
calipers that appear. Caliper Length appears at lower right.
Export Results
The Export button enables you to export the results of the RNFL Thickness analysis. This
feature enables you to further analyze and manipulate the data using third party software.
When you click Export, the Export As dialog appears as below:
Figure 6-10 The Export As Dialog
• The dialog prompts you for a filename. You can name the file and save it in any
available location. The default name is Export_1. The output is a set of six files with
the same name and different extensions, for example:
Export_1.txt(patient informatio
n in ASCII text format)
Export_1.raw(raw scan data in binary format)
Export_1.bmp(processed scan image in
bitmap format)
Export_1.vi1(fundus video im
age in bitmap format)
Export_1.spd(raw scan data in ASCII text format)
Export_1.rnf(RNFL Thickness result
in ASCII text format)
Note: It is the clinician’s responsibility to associate patient information with
exported files.
RNFL Thickness Average
Application: Select RNFL Thickness Average to obtain graphs of RNFL thickness averaged
over multiple circle scans of equal radius around the optic disc (peripapillary region). You
can apply this analysis to one OD and/or one OS scan group of equal radius made from the
Circle, Proportional Circle, (F
AST) RNFL Thickness (3.4), RNFL Thickness
(2.27xdisc) or Nerve Head Circle protocols. Normative data will appear in the output
if you analyze Fast RNFL Thickness (3.4) or RNFL Thickness (3.4) scans with the
