Direct the pointer pen under an angle toward the screen (like in writing) to enable you to see your entries.
The “Examination – PROGRAMS” site allows defining three versions of each program marked P-V1 to P-V3 with different parameters for test strategy, number of catch trials, fixation marks, etc. The perimeter connects to any Voltage from 100– 240 VAC, 50/60 Hz, 40VA. Attention: On the original motorized table, set the voltage selector at the inside panel. Connect the perimeter power cord to the socket in the table.

Print Visual Fields
The Seven-in-One print-out is the standard OCTOPUS 301 format to report the visual field data.
Modify Test Conditions
Before the Examination Several parameters can be selected to be used regularly. This makes it simple to routinely repeat the same test procedure. For details refer to § 7 in this guide and the User’s Manual. After you made these selections under available when starting an examination.
, they are readily
Mark one or several examinations. Then go to “DISPLAY” to obtain a display of the visual field. Here a CO-Greyscale and Table. These settings can be modified any time before pointing OK to start the examination. Touch the Program field and change to another program. The Strategy field allows you to select Normal, Dynamic or TOP (optional) strategy. If the eye is close to the trial lens, the image is in focus. Important: Adjust the Video control to obtain the best possible contrast between pupil and iris. Center the eye by using the pointing arrows. Touch on the Start button. During the examination the eye is clearly visible and the test data (upper left) is updated continuously. Especially in the beginning, watch the patient’s response on the positive and negative catch trials. If the patient clearly makes mistakes it is recommended to instruct the patient again. Touch Stop and Restart the test. You may look at the eye monitor to check fixation or see the intermediate results. To switch from the eye image to the measured data. Touch to display results and eye image.

If not on automatic (option), center the eye with the pointer arrows if the patient lost fixation. A bar Indicator shows the progress in time. The Defect Level Indicator provides information about the status of the results (except when using the TOP strategy and the LVC and ST programs) if the visual field is likely to be normal or how much it is depressed.
In the Fixation target field one of three fixation marks is chosen. If it is desired to have an automatic print-out, select Auto next to Report. During the examination The following controls can be modified after touching on the respective button and pointing the arrows. It is recommended to turn the Sensor OFF. With Sensor ON, a message signals when the patient’s head moved away from its correct position. Go to Pupil to enter pupil size manually indicated by Pupil * . Otherwise the pupil size is measured automatically. Use Interval to change the time between stimuli, or leave it to “adaptive”. Control is used to modify eye fixation sensitivity and to set the Auto Eye Tracking (option) on “auto”. Touch on Video to (re)adjust for the best possible contrast between the pupil and iris. This is important for the correct functioning of the Auto Eye Tracking. With Fixation the brightness of the fixation mark can be changed. Modified settings remain active for the next examination.
You will find the Patient data at the top (left) and the examination data (right). With the black pointers you can now select further images of the same examination. With the white “file” icons the other, previously selected examinations, are displayed.

It is recommended to enter the particular patient data and the data related to the examined eye before the examination. However, the missing information can also be added at a later time - before printing the results.
Because the data is compared with the age corrected normal values, an incorrect date of birth like 1956 in stead of 1965 makes 1dB difference in the CO values.
Behind the “EDIT” tab is a page where the patient data can be changed (completed or modified) and where the selected examination(s) can be exported to a PC or deleted. For example: Follow “Edit – Change – Eye” to ad eye data Save the entries Touch

A trial lens of +1D in stead of –1D makes a difference of approximately 2dB. To compare fields in a trend analysis, check if the different pupil sizes do not vary too much. A normal grey scale shows darker shades towards the periphery because of the slope of the visual field. With the Bebie Curve (or Defect Curve) a uniform defect can easily be seen. Such a deviation can have several causes: Small pupil Incorrect trial lens Cataract Early sign of glaucoma The global indices provide a quantitative assessment at a glance.
