TESTING
Once the test preparations are complete and the patient is ready to begin,
•
Select
the
Start Test
Button located on the lower left of the Testing Screen to begin the test.
•
If the
Patient Visor
is not in the correct position for the test selected, the
Patient Response
Button
is not connected properly, there is too much ambient light, or calibration is needed,
then an error message will appear when the Start Test Button is selected.
Once the test starts there is a test progress bar indicating “Testing…” below the chart display on
the right side of the screen. The tested visual field location is indicated on the chart display
throughout the test. There are also two buttons on the lower left of the screen to control the
test:
Pause
: Selecting this button pauses the test. When paused the progress bar will say,
“Paused…” and the Pause Button changes to Resume Test. Pressing the Resume Test
Button will resume the test.
Cancel
: Selecting this button will bring up a prompt asking “Are you sure you want to cancel
the test?” Clicking on the
No
button will resume the test, while clicking on the
Yes
button
will delete the data collected during that test and bring up four options:
Re-Test Right (Left):
Select this button to repeat the test on the same eye.
Test Left (Right) Eye:
Select this button to test the opposite eye.
New Test:
Select this button to bring up the original Testing Screen for the same patient for
additional testing.
Done Testing:
Selecting this button returns to the Main Menu.
At any time during the test the patient may press and hold the Response Button to pause the
test. The test will resume automatically when the Response Button is released.
Once the test for the first eye is complete the instrument will beep momentarily. Choose one of
the three options relative to testing the second eye:
Start Left (Right) Eye
: Select this button to perform the same test type on the other eye.
New Test
: Select this button to bring up the original Testing Screen for the same patient for
additional testing.
Done Testing
: Selecting this button returns to the Main Menu.
You may enter “
Notes
” or Patient “
Info
rmation” at any time before, during or after the test by
selecting the appropriate tab. You may want to note how well the patient maintained fixation
during the test, or record pupil diameter information, for example.
At the completion of each eye test, the results are displayed on the Operator LCD. When the
testing for both eyes is completed, the results are automatically saved to the instrument’s hard
drive, to the floppy drive (if enabled), and sent to the printer (if enabled- see System Settings
(F5)). The floppy drive is used for automatic short-term backup on a test-by-test basis.
We recommend that you also back up your testing database to a CD-R media every week from
the MAIN MENU (F1) or the FILE FUNCTIONS (F4) Screen. As most CD-R disks are limited to
about 48 separate writes, you can back up almost a year’s worth of tests on a single CD-R media.
