4-2 TEST PARAMETERS AND STRATEGIES
REV.B 02/03 PN 51680-1 HUMPHREY FIELD ANALYZER II - i series
Test parameters are the testing conditions used during a test, e.g. stimulus size, test strategy,
test speed, etc. While the majority of patients are best examined using “standard” parameters
(or default parameters), you can alter the parameter settings for purposes of tailoring the test
to meet particular patient needs.
An example of a test parameter is the fixation target which has four settings: central, small
diamond, large diamond, and bottom LED. The central fixation light is the default target. It is
suitable for most patients, but you can change it if the patient requires a larger target.

To change test parameters
You can access the parameter setup screens two ways:
• From the Start Test screen via CHANGE PARAMETERS.
• From the Test in Progress and Pause screens; during testing only test speed and fixation
monitoring can be changed.
