Peripheral Testing Limits
The projection system has limits on how far out it can project a light stimulus. The following graph
shows the projector’s limitation when using the 80° field size:

Figure 13.1 Peripheral 80° Testing Limits for Selected Meridians
Presenting a Stimulus Along a Meridian
When activated, the HFA II-
i
will display the stimulus inside the bowl for one second at the starting
point of the chosen meridian. It then will begin moving the stimulus toward fixation and into the
patient’s field of vision. If the patient does not respond by the time the stimulus reaches the central
fixation point, the light will turn off and the instrument will beep.
Note: The first stimulus of each isopter will be delayed longer than the one second described above.
This is because the HFA II-
i
is verifying the stimulus before beginning the isopter.
