NTRODUCTION
The OCTOPUS 1-2-3 is a direct projection perimeter to
examine the central 30° visual field. For data storage,
display and analysis we recommend to use the (optional)
P
ERITREND
software.
Your local OCTOPUS distributor who is also responsible
for instructing the operating staff will install the
OCTOPUS 1-2-3.

HE EXAMINATION
After switching ON, the perimeter asks for calibration (first
screen). Normally the ocular cap is sufficient to darken
the room .
The second screen should be answered depending on
the state of the buffer.
From the main screen (Figure 1-2) there are two ways to
start an examination.
2.1 Examinations Using a Procedure Code
It is good practice to use a Procedure Code (see 1.7):
! In the menu, highlight ‘Code’ and press OK.
Enter the code number and press OK (twice).
!
2.2 Manual Operation
In ‘Manual’ all selections can be made as follows:
! In the menu, highlight ‘Manual’ and press OK.
The selection of the L/R eye is established automatically
with the position of the perimeter.
Using the
and keys select the examination
program, test strategy and fixation target. Press OK.
2.3 Enter Patient Data
There is the choice (Figure 2-1) of entering new patient
data, test the same patient (other eye) or to take the
patient data from the buffer memory (see section 3).
2.4 Position the Patient
Position the patient straight up but comfortably on the
chair. Apply the eye occluder and hand the patient the
patient button.
CAUTION: Only the answer buttons produced by INTERZEAG
should be connected to the perimeter.
2.4.1 Instruct the Patient
To obtain reliable examination results, instruct the patient
in all detail about the examination procedure.
In particular inform the patient
• to maintain fixation and to blink regularly to avoid dry
eyes;
• to press the button only when a stimulus is thought to
be seen;
• not to worry because the bracketing procedure is
characterized by the fact that approximately half of the
stimuli can not be seen;
Tell the patient how long test is going to take.
NOTE: The patient can always stop the procedure by closing
the eye or by keeping the response button pressed.
2.4.2 Setting the Trial Lens(es)
The lens holder has 10° marks as shown (Figure 2-2) for
aligning the cylindrical lens axis correctly.
NOTE: The patient is corrected with her/his far correction. No
correction is needed for presbyopic eyes.
Use only small rim
correction lenses!
Figure 2-2
2.5 Monitoring the Examination
Figure 2-1
It is mandatory to type in the date of birth (or age,
!
see 1.3).
!
It is recommended to also enter the ID number, and
Sex by using the and keys.
!
The other information is optional.
!
NOTE: It is important to measure and enter the pupil size
during the examination (2.5.1).

IMPORTANT: The operator should not leave the patient unattended,
especially when the patient is new to this type of
examination.
NOTE: Restart the examination when the patient obviously has
not yet understood the procedure.
The following is part of the routine during the
examination:
2.5.1 Pupil Diameter
The ruler on the monitor allows a quick measurement of
the pupil size (scale in mm).
!
Highlight ‘Input’. Press OK.
!
Enter the pupil size in the patient data. The eye
fixation control remains active even if the eye is not
shown.
2.5.2 Stimulus Interval
The stimulus interval is adapted to the reaction time of
the patient. If the patient finds the speed too fast,
Highlight ‘Interval’. Press OK.
!
The speed will now be constant and slow. ‘Interval*’ is
marked to signal the operator that the speed is fixed.
2.5.3 Eye Fixation
Behind the screen the pupil position is controlled by an
‘invisible’ measuring cursor. If the pupil size is smaller
than 2 mm or larger than 6 mm:
Press OK to ‘Stop’.
!
Highlight ‘Cursor’ and press OK.
!
Adjust eye fixation control from ‘normal’ to the
!
respective value ‘small’ or ‘large’. Press OK.
In case the pupil size is very narrow or when the
!
patient can not fixate at all, switch the eye fixation
control to ‘no control’. Press OK.
Press ESC to return.
!
2.5.4 Fixation Brightness
Sometimes the patient can not fixate well because the
fixation mark is too dim or to bright.
Press OK to ‘Stop’.
!
Highlight ‘Fixation’ and press OK.
!
!
Using the keys switch to brighter (dimmer for
reverse action) and increase the intensity by
pressing OK several times.
! Press ESC to return.
NOTE: It is not recommended to change the brightness too
much to avoid blinding and contrast effects.
2.5.5 End
OCTOPUS examinations are run in stages. If the
operator wishes to stop the test at the end of a stage:
! Highlight ‘End’ and press OK.
‘End*’ is now marked and the procedure will stop
automatically after the end of the stage.
At this point, the Examination can be continued or saved.
2.6 On-screen Information
# Questions: The number of stimuli (including
repetitions) that have been presented.
# Repetitions: The number of stimuli that have been
repeated. Stimuli are repeated when the patient closes
the eye or reacts within 100 ms after the stimulus is
displayed.
# False pos.: The total number and the number of falsely
answered positive catch trials.
# False neg.: The total number and the number of falsely
answered negative catch trials.
# Elapsed time: Elapsed examination time. Time that
