DEMO

This feature runs a short practice test. Demo allows the patient to preview what is required

during a visual field test. It also allows you to evaluate whether the patient understands your

instructions and the use of the patient response button. Patient responses are not recorded

during the Demo test. The Demo test starts immediately after you press DEMO.

The Demo test will run for one

minute unless you choose to end

the Demo test  sooner. Once the

patient demonstrates compe-

tency, press END DEMO to begin

the actual test. If END DEMO is

not pressed, the pop-up window

will disappear after one minute.

The test will immediately begin.

Note: The Demo test runs only after the Foveal Threshold is determined and the Gaze

Tracking initialization is complete (if utilizing either of these features).

TEST OTHER EYE

This button allows you to switch to the Start of Test screen for the other eye. You will be

allowed to add or change patient data at this time.

INTERNAL DIAGNOSTIC ALERT

Frequently, after selecting START or TEST OTHER EYE, the message “Please Wait... Preparing

Instrument For Test” appears on the screen. This is a normal function of your instrument. The

HFA II is performing a short, self-diagnostic check prior to beginning the test.
