Patient Testing
5-11
The T
ESTING
Screen (
Figure 5-8
) allows you to prepare the patient for the test and to
confirm or modify the testing configuration selections, if needed, prior to performing the
visual field test.
The status box under the chart on the right side of the screen shows that the Pre-test Demo
is running. Until the test is started, stimulus presentations for the selected test are
automatically displayed to demonstrate the test to the patient.
1. Confirm that the patient’s name, ID and date of birth are correct. Return to V
IEW
P
ATIENTS
(F2) if changes are needed (only in local database).
2. Confirm the desired Test Type is selected in the upper right of the screen.
3. Also, confirm proper selection of the Folder, Test Speed, and Fixation Target. Refer to
the
System Settings – Testing
on page
2-5
for more information. You can change
each of these by using the pull down menu (click on the arrow to change if necessary).
You can alter the first eye tested in this screen by selecting the OD (RIGHT) or OS (LEFT)
buttons above the chart.
In the T
ESTING
Screen, the video eye monitoring will display a live image of the patient’s eye
to aid in proper alignment of the patient and to ensure fixation during testing. Selecting
the Freeze button will freeze the live image of the eye. This provides the capability to
measure the pupil size using the increments on the cross hair in the frozen video image.
The markings on the cross hair are in 1mm increments. Press the Unfreeze button to return
to live video.
