KINETIC TESTING
The alphabetic characters for the
isopters currently being displayed
will each have an “X” in the box
adjacent to it. To add or remove
the isopters that are displayed,
choose the box next to each
isopter to select or deselect them.
A maximum of three (3) isopters
can be displayed at any one time.
Press SELECTION COMPLETE to
view only the chosen isopters.
ADD ISOPTER LINES
Pressing this button draws lines that connect the test points for each isopter chosen with SHOW
ALTERNATE ISOPTERS. The more points the instrument has to work with, the more accurately
this function will represent a patient’s isopter.
Note: The locations mapped with Scotoma Mapping, Blind Spot Map, and Custom Scan are
not connected with this feature.
ZOOM TO 30/EXPAND TO 80
This button toggles between the 30˚ and 80˚ field formats. This feature is especially useful when
the user wants to see the central 30˚ of an 80˚ field in detail. Pressing this button does not
eliminate the points outside of the central 30˚. These points may be viewed again by pressing
EXPAND TO 80.
TEST OTHER EYE
Pressing this button allows the user to begin testing on the patient’s other eye. Only press this
after the first eye is finished being tested.
CANCEL TEST
This button deletes all data on the current test and takes the user back to the Start of Test
screen. A dialog box warns the operator that the test will be canceled. Pressing YES will cancel
the test. Pressing NO will return the user to the End of Test screen without affecting the test
data. Even if a test is deleted using CANCEL TEST, patient data will be unchanged.
Printing can be performed via the PRINT FUNCTIONS icon on the right-hand side of the screen.
After pressing this icon, the Kinetic Printout Selection screen is displayed. Refer to step 5 in
“Printing Sequence” later in this section. Also see “Printing Kinetic Tests” for further
information.

After all of the adjustments are made and the data is saved, press the MAIN MENU icon to
exit Kinetic Testing.
