Designing a Custom Kinetic Test Pattern
You also can create and store Custom Kinetic test patterns. This is similar to the custom static
Screening and Threshold tests that are described in
Chapter (12), "Custom Testing." Custom Kinetic
tests always are created for the right eye only. When you test the left eye, the HFA II- i will flip the
test pattern to accommodate for the mirrored physiological differences.
Note: You may begin testing with either the right or left eye.
You must create Custom Kinetic tests. Once created, you may save them and then access them for
future testing. You access them by selecting the SHOW TEST LIBRARY button from the Main Menu
screen, then choosing the KINETIC button. There is room for ten (10) Kinetic tests to be stored on
the Kinetic Tests menu at any time. Some Kinetic tests may need to be deleted if the menu is full.

Figure 13.6 The Nasal / Temporal Relationship for the Right Eye
Remember, the Custom test pattern you are designing must be for the right eye. Therefore, temporal
points will be plotted to the right (meridians 0 to 89 and 271 to 359) and nasal test points will be to
the left (meridians 91 to 269). Testing for the left eye will automatically be reversed.
Example: Programming a point to be presented along the 45 degree meridian (in the temporal
visual field) for the right eye will be presented along the 135 degree meridian (temporal visual field)
for the left eye.
Order of Stimulus Presentation
You have two choices for the display of the test points. One way is to have the HFA II-
i
randomize
the stimuli for testing. You can enter the points in any order you choose as you create your Custom
Kinetic test. You probably will wish to enter the meridians to be tested in a logical sequence
(Example: 20 degrees, 40 degrees, 60 degrees...).
The second way is to enter the points in the exact order you wish to have them presented. If you
wish to test the superior temporal quadrant first, be sure to select the meridians between 0 degrees
and 90 degrees, at the start of your new custom test. If you wish to test at 20 degrees, then at 40
degrees and then at 60 degrees for the right eye (180, 160, 140 degrees for the left eye), make sure
you enter the 20, 40 and 60 degree meridians in that order. Remember: the order you list the
meridians will be the exact order of presentation every time the test is run.
