Press ENTER / RETURN on your keyboard or activate the Scotoma Map button on the
screen. After a slight pause, the HFA II will automatically map the scotoma according to
the meridian pattern chosen.
Notes:
1. The Humphrey Field Analyzer II does not automatically monitor the patient’s fixation
during kinetic perimetry. For reliable test results, it is imperative that the operator
constantly monitor fixation with the video eye monitor.
2. The HFA II will automatically map the scotoma according to the test parameters chosen.
The user cannot initiate each test stimulus individually. When the patient presses the
response button, the HFA II will switch to the next meridian and immediately start
testing.

During the test, a small
diamond moves across the
video display. It displays the
progress of the stimulus in the
test bowl.
Note: The diamond may be difficult to see during Special Mapping operations.

When the Scotoma
Mapping finishes, the test
stops.
An uppercase letter marks each
location where the patient
pressed the response button.
Note: Each time a new isopter or test sequence is performed, a new uppercase letter will
be displayed on the test screen. Even if the same stimulus value used for mapping a
scotoma was used for a previous isopter, a different letter will be indicated.
