Selecting the Meridian with the Keypad
To present a stimulus manually to a patien
t using the Keypad, follow these steps:
1From 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.
2A keypad will appear as a pop-up window.
Input the meridian value (in degrees) for the test
stimulus.
Using the external keyboard (optional on 720
i
, 740
i
, and 745
i
) may be
easier for entering the meridian values. You also can use the
RETURN/ENTER key 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 when
he or she sees the light. See “Preparing the Patient,” on page 3-24, 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-
i
does not monitor the patient’s fixation automatically during
kinetic perimetry. Both Gaze Tracking and Blind Spot Monitoring are turned off. For reliable test
results, it is imperative that you constantly monitor fixation with the video eye monitor.
