Click on the Advanced Export button on the ONH and RNFL OU Analysis screen, to
export and store ILM-RNFL thickness maps as .DAT files and .txt files of Neuro-retinal Rim
Thickness and RNFL Thickness profiles to a user-selectable directory
Dat Files of ILM–RNFL Thickness Maps
NOTE: DAT files are plain text files that can be read from an Excel or Matlab application.
Each comma–delimited value is the thickness of an A-scan. Each row represents a fast
B-scan. Each column represents a slow B-scan, as shown in the figure below. The first row
represents the topmost fast B-scan and the first column represents the leftmost slow
B-scan.
Txt Profiles of Neuro–retinal Rim Thickness and RNFL Thickness
The profiles of Neuro–retinal Rim Thickness and RNFL Thickness are saved to .txt files by
clicking on the Advanced Export button on the ONH and RNFL OU Analysis screen. The
files are plain text files.
The neuro–retinal rim thickness values at 180 points, each point representing 2 degrees,
are saved. Furthermore, the RNFL thickness values at 256 points, each point representing
1.41 degrees, are saved in the files.
For both profiles, the thickness data points start from temporal, to superior, nasal, inferior
and finally back to temporal — the same direction as on the screen. Patient and exam
information is also saved in these files.
Move Scan Data (Native Mode Only)
Occasionally, in Native Mode, a scan is acquired and saved in the wrong person’s file.
Scans that are incorrectly stored can be moved to a different file by using the Move Scan
feature. To access the Move Scan dialog:
1. Open the file with the incorrect or misplaced scan and choose an analysis to display
the data. For example, for a Macula Cube scan, choose Macular Thickness analysis.
