SOCIAL SECURITY
ADMINISTRATION
KINETIC DISABILITY
TEST
The HFA II offers a special kinetic test authorized by the Social Security Administration. This test
is used to evaluate a patient’s visual field and creates a numerical score of the patient’s visual
disability. Eight (8) meridians are tested with a standardized stimulus (III 4 E). The stimulus
moves at a rate of 4 degrees per second. The test uses the full field starting point for the
stimulus. Only one isopter is determined. At the end of the test, the Humphrey Field Analyzer will
calculate an Efficiency Score and display this value on the printout. The exact values of the 8
points should also be printed for your records and are included in the Numeric Values printout.
These meridians are randomly tested:
0, 45, 90, 135, 180, 225, 270, 315 degrees

You will be given the option of Automatic or Step by Step operation. The Automatic mode will
run to completion. Step by Step will give you the option to retest a meridian. You may also use
the Special Mapping features at the end of the test. Special Mapping features will not change the
