KINETIC TESTING
Selecting the meridian by
using the keypad
REV. B 02/03 PN 51680-1
To present a stimulus manually to a patient using the Keypad, follow the steps below:
1
From the Kinetic Test
screen, choose SELECT
MERIDIAN. The button in the
lower left-hand corner should
say " USE CURSOR" for the
Keypad to be active. If the
button says "USE KEYPAD",
press prior to selecting the
meridian.
2
A keypad will appear
as a pop-up window.
Input the meridian value
(in degrees) for the test stimulus.
Using the optional external
keyboard may be easier for
entering the meridian values. The
RETURN/ENTER key can also be
used to start the test.
Note: Meridians are positive, whole numbers between 0˚ and 359˚.
3
Prepare the patient for the test. Explain that the light will not be seen for a short time and
then it will move into the patient's field of vision. Ask the patient to press the response
button as soon as the light is seen. See Section 3: "Preparing the Patient" for additional details.
4
Press ENTER. After a slight pause, the test stimulus will begin to move toward the fixation
point in the middle of the bowl.
Note: The Humphrey Field Analyzer II does not automatically monitor the patient's
fixation during kinetic perimetry. Both Gaze Tracking and Blind Spot Monitoring are
turned off. For reliable test results, it is imperative that the operator constantly monitor
fixation with the video eye monitor.
