Test Library Notes
There are a number of different uses for the tests included with your HFA II- i . Some have special
settings or conditions that are important to understand if you are to perform the test correctly.
• The Bottom LED fixation target is automatically used by the HFA II-
i
in order to test all points of
the Superior 36 point or Superior 64 point Screening Test. Remember to direct the patient’s
fixation to this lower target. If you manually set the Central target to be used with either of the
Superior Field tests, some of the most superior points will be omitted from the test pattern.
These two tests should be run in the Single Intensity mode with the stimulus set to 10 dB. If you
use these tests often, refer to
“Altering the Main Menu Screen,” on page 2-26 , for information
on how to place the test on the Main Menu with the 10 dB stimulus permanently set.
• The Full Field tests are run in two parts: first the central portion and then the peripheral
portion. If a trial lens is necessary for the central portion, the HFA II-
i
recognizes that the trial
lens holder is in the up position and pauses the test at the completion of the central portion.
An alert advises you to remove the trial lens and put the trial lens holder in the down position.
You may then start the peripheral portion of the exam. If the patient does not require a trial
lens correction at the start of the exam (trial lens holder in the “down” position), the Full Field
test will run to completion, testing both the central and peripheral visual field without pausing.
• The Full Field 135 Screening Test will not display all tested points on the screen. However, the
HFA II-
i
will test all points and they may be viewed on the printout.
• To better view the central portion of any completed Full Field test, use the ZOOM button
located on the End of Test or View Test screen.
• Any Full Field test that has had its central 30 degrees tested, may be saved, printed, and later
recalled from disk without completing the peripheral portion of the test.
• The Central 76 point test grid is identical to that of the 30-2 Central threshold test. This allows
you to follow up screening tests with threshold testing at the same points. Similarly, the
Peripheral 60 screening test has the same test pattern as the 60-4 threshold test.
