Step 1: Select a Valid Follow-Up Exam
You can select a valid Follow-up exam for a GPA report in four ways, each of which is described below.
The exam you select is the “Key Exam.”
Criteria for a Valid GPA Follow-up Exam
To generate a GPA report, the selected exam must be a valid Follow-up exam. A valid GPA Follow-up
exam meets all the following criteria:
• A single SITA test (per eye) from one patient is selected.
• The selected exam was not previously de-selected from the GPA analysis for that patient and
eye. If it was de-selected, you must re-select it before it will be valid again for GPA.
• The selected exam does not pre-date either of the current Baseline exams. If it does pre-date
either Baseline exam, you must change the Baseline exam selections, if possible.
If these criteria are not met, you will only be able to get non-GPA reports, such as the Classic Single
Field Analysis.
Selection Method 1: Select Follow-up Exam from Current Test Results at End of Exam
To create a GPA printout from the current test results:
1. At the end of a SITA Standard or SITA Fast test, select the PRINT FUNCTIONS icon.
2. The Threshold Printout Selection screen appears with print options. See “Step 2: Select Reports
from Threshold Printout Selection Screen,” on page 8-31 . If you have just tested both eyes, it is
possible to choose different printouts for right and left eye; the selections need not be the
same for both.
Selection Method 2: Select Follow-up Exam from Stored Tests
Follow these steps to print a GPA printout using stored tests:
1. Select the PRINT FUNCTIONS icon from any screen where the PRINT FUNCTIONS icon is active.
The Disk Options screen appears.
2. Choose the Source (
HARD DRIVE
,
FLOPPY, DICOM ARCHIVE,
or a USB storage device) from the
drop-down menu and press
PROCEED
. The keyboard appears. Use the keys and press
ENTER
to
search by last name.
3. From the File Directory, select for one patient one SITA test (24-2 or 30-2) for either or both
eyes and press
PROCEED
.
Note: The exam you select is the one for which the GPA Summary or SFA GPA will be printed, if you
have chosen one of these report formats.
4. The Threshold Printout Selection screen will appear with print options. See “Step 2: Select
Reports from Threshold Printout Selection Screen,” on page 8-31 .
Selection Method 3: Select Follow-up Exam from Recall Last Test
The HFA holds in temporary memory the last right eye and left eye tested (they need not be for the
same patient) until the instrument is powered off, at which time the memory is cleared.
If a test held in memory is a SITA test, you can generate a GPA printout as follows:
1. From the Main Menu screen, select RECALL LAST TEST.
