Full GPA and Last Three Follow Up Reports
The Full GPA report is a multi-page overview of t
he patient’s entire history. The Baseline page
provides Grayscale, Numeric, Total Deviation, and Pattern Deviation Plots, as well as key indices for
both GPA Baseline tests. The VFI Plot and Bar are displayed at the bottom. Subsequent pages show
three Follow-up tests per page in the format: Grayscale, Pattern Deviation, Deviation from Baseline,
Progression Analysis, key indices, and the GPA alert. The GPA Last Three Follow Up Report follows
the same format, but includes only the three most recent Follow-up tests.
Three in One Report
If threshold test patterns or test parameters do not meet
the criteria for STATPAC analysis, results are
presented in Grayscale, Numeric, and Defect Depth formats on the Three in One report. The
numbers that appear outside each quadrant of the numeric grid are called quad totals and
represent a summation of the threshold values determined in each quadrant. This format is available
for 10-2, 24-2, 30-2 central field tests, and for the peripheral 60-4 test. The nasal step Three in One
test report displays only threshold and defect depth data.
