The HFA II-

’s Kinetic feature is designed for those experienced in standard Goldmann perimetry.
Thus, the instructions and illustrations in this user’s manual act as a guide to performing kinetic
perimetry. This chapter is not intended to serve as a textbook for teaching an inexperienced
technician the principles and strategies of kinetic visual field examination. There are textbooks and
continuing education programs available for that purpose.
By the end of this section you will be familiar with:
• how to run a Kinetic test in either the Manual, Step by Step, or Automatic mode
• how to print and save Kinetic test results
• how to use the Special Mapping options
• how to create a Custom Kinetic test
Introduction to Kinetic Testing
There are a number of ways that you can perform Kinetic testing on your Humphrey Field Analyzer.
You can:
• Choose the test points manually.
• Choose the starting location by moving a cursor to the point, or by entering coordinates
from the keypad.
• Move the cursor by using almost any standard external entry device. This can be a glidepad,
trackball or a mouse.
• Use your finger, while pressing the touch screen, to move the cursor to the desired location.
• Present the stimulus using the external keyboard, an external entry device, or the touch
screen.
• Display test points automatically by using pre-programmed testing sequences. There are a
number of these tests available, each with a different amount of separation between the
points. Both the vertical and horizontal midlines are tested in each pattern. These tests can
be “fully” automatic or can be used to select the next test point, yet still allow you to
activate the stimulus (Step by Step mode). Currently these pre-programmed test sequences
are limited to one isopter (III 4E).
• Create Custom Kinetic patterns and store them for repeated use. You can run these custom
tests in Manual, Automatic or Step by Step mode. You can use multiple isopters (up to 10)
with these Custom Kinetic patterns.
• Test isolated areas using the Special Mapping features. For example, you can map the blind
spot, scotomas, and single static points using special features that are available in this
kinetic package. Testing of isopters away from the point of fixation is available using the
Custom Scan option.
One example of a programmed test available for Kinetic testing is the Social Security
Administration’s “Kinetic Disability Test.” This Kinetic test can help you to qualify patients with visual
deficits for benefits as determined by the Social Security Administration. This single isopter test
includes eight meridians and calculates an Efficiency Score which is indicated on the printout at the
end of the test. Carl Zeiss Meditec is grateful to the Social Security Administration for making this
test available on the Humphrey Field Analyzer for your use.
