Single Field Analysis with GPA (SFA GPA)
The SFA GPA, a Single Field Analysis printout that includes GPA results, is pictured in Figure 8.2 . The
GPA information box includes the Progression Analysis Probability Plot for this test, along with the
exam dates for the GPA Baseline exams and the two previous Follow-up exams. The GPA Alert, VFI,
MD, and PSD values are also displayed here.
Full GPA Report
The Full GPA report is a multi-page overview of the patient’s entire history, comprised of a Baseline
page (
Figure 8.3 ) followed by multiple Follow-up pages ( Figure 8.4 ). The Baseline page provides
detailed information on the two GPA Baseline exams, including Graytone Plot, Threshold (dB) Plot,
Total Deviation Plot, Pattern Deviation Plot, and key indices including VFI, MD, and PSD. The VFI
Plot and VFI Bar are shown at the bottom of the first page of the Full GPA report. Subsequent pages
of the Full GPA report show three Follow-up exams per page in the format: Graytone, Pattern
Deviation, Deviation from Baseline, Progression Analysis, and key indices. Up to 14 Follow-up exams
may be included.
GPA Last 3 Follow-up Report
The GPA Last 3 Follow-up report follows the same format as the Full GPA report, but includes only
the three most recent Follow-up exams. This report is always two pages long when printed.
