An electrically adjustable instrument table optional makes it possible to comfortably adjust the height of the instrument to the individual size of the patient.
The instrument table is delivered in a separate package. Utilize the instructions included with the table to put the table together and take care to select the correct voltage before connecting the power cord. Handle the instrument using both lower housing halves to lift it out of the packing. Two ribbed grips hinder sideways slipping.
Do not use the forehead rest as a carrying handle during unpacking or transportation! In order, though, to make the examination conditions pleasant for the patient and for obtaining reliable results, the instrument is to be placed in the room so that no direct light falls on the instrument or the patient.
The positioning between the patient and the operator or the operating panel can be so chosen that the room conditions are optimally used. Loosen the three Allen head screws roughly 2 turns counterclockwise on the perimeter of the headrest holder Allen wrench is included with the accessories and turn the headrest together with the optical unit into the desired position.
Tighten the three Allen head screws again. A complete rotation around the column is blocked by a built in limit. Place the instrument on the table so that the opening of the table foot and the headrest are in the same direction.
Stick the connector plug so far into the connector housing that the catches audibly click. Plug the power cord in. A change of voltage on the instrument is not required. If an instrument table was delivered with the unit, the OCTOPUS can be connected using the power socket in the electronics box of the instrument table.
For application software installation and upgrade refer to Chapter 7. Basically all the functions are present in the software, but some can only be made accessible with a code. Enter new dongle code. The keyboard is only released, when the serial number of the instrument is stored in the memory. To print out the complete instrument information see Chapter 8. The 'Dongle code' function is only used, when additional program options have been purchased.
To avoid. The 'Dongle' button is only released after the. As from Serial No. In this case hold your hand close in. Sends the serial no. Based on the serial no. Before the instrument saves the setting, the parameters are verified by the system.
A faulty. The message 'Dongle Code not accepted' is displayed on the. The complete dongle code consists of a multi-digit three part series of numbers see example on the left.
Entering the code is done via 'Setup' — 'Service' — 'Dongle'. Every dongle code is unique and only valid for a specific instrument. Mistakes made while entering it or the entering of it into the false instrument false serial no.
Changing to the old code is possible at all times. By means of the. This technique does not require dark room condition to take a visual field. The required dynamic range of the stimulus intensity of 40 dB ' is achieved with a combined control mode:. Cluster Analysis supports detection of glaucomatous defects by clustering visual field defects along nerve fiber bundles and displays them as a Cluster MD Mean Defect to highlight significant pathological regions.
As a local average is used, Cluster Analysis gives you a higher chance of detecting early localised glaucomatous damage than the global index Mean Defect MD. However, it is less influenced by fluctuation than individual test points. Glaucomatous progression is often slow and influenced by fluctuation. Why not let Cluster Trend be your guide in assessing change? This allows you to identify glaucomatous change at a glance. Combining the results of both structure and function is key to obtaining a comprehensive assessment of the onset and progression of glaucoma.
The Octopus Polar Analysis projects local visual field defects along the nerve fibers to the optic disk and displays them oriented as structural results. This makes structure-function correlation almost intuitive. Polar Analysis is available in both single field and trend view. With Polar Analysis, the nerve fibre bundles that are in danger or defective are easily identified.
Local defects are projected along the nerve fibres to the optic disk and are represented as red lines. The projected defects are vertically mirrored to look like a structural result and are scaled with rings for 10, 20 and 30 dB deviation. Do you see glaucomatous progression in your structural results?
Then consult Polar Trend to see whether you can find matching visual field deterioration. Polar Trend is based on the Polar Analysis. Appreciate the same characteristics and kinetic flexibility as offered by the original Goldmann perimeter and further benefit from simplified and more consistent operation.
Enjoy the characteristics of the manual Goldmann perimeter in a modern device with automatic electronic data filing. As with the manual Goldmann perimeter, you can place vectors anywhere you want and even draw them manually in the standard Goldmann sizes, I to V, and intensities, 1a to 4e. In this way, you can achieve diagnostic results comparable to those from a manual Goldmann perimeter. The Octopus semi-automated kinetic perimetry retains all the original characteristics and specifications of a manual Goldmann perimeter.
This allows for a smooth transition. Enjoy the same Goldmann stimulus sizes, I to V, and the same stimulus intensities, 1a to 4e, as you are used to. The design is also comparable. An original Goldmann bowl with a radius of 30 cm in all directions is used to project stimuli onto the Goldmann background intensity. Place vectors anywhere and in any direction you want in either a semi-automatic or free-hand mode. Static points are also possible and isopters can be defined manually or in automatic mode if the isopter is regularly shaped.
Equipped with all these possibilities, you can keep testing your patients with exactly the same methodologies as before. Benefit from the flexibility of a manual Goldmann but enjoy simplified and more consistent operation. Vector speed is now controlled and thus repeatable; the influence of both operator and patient reaction time is mostly eliminated and normal isopters provide guidance.
And why not translate your standard clinical testing protocol into a template for all your patients that you can still adapt depending on the pathology?
Choose a fixed vector speed and standardise your testing for more consistent results. In addition, variability due to operator reaction time is completely eliminated, as patient responses are immediately marked by pressing the response button.
Patient reaction time adds variability to a kinetic examination, especially in patients with inconsistent reaction time between sessions. Octopus perimeters therefore allow you to measure patient reaction time by presenting stimuli in the patient's visible area and to compensate for it.
Standardise your clinical workflow without losing the flexibility to adapt to individual situations. Translate your kinetic testing protocols into a template and use that template for a standardised testing methodology independent of the operator. Then, depending on the pathology and patient response, adapt the template by adding and deleting vectors during the test.
Or take advantage of templates developed by Dr. Enjoy the reliability of Octopus perimeters, for example with Octopus Fixation Control which automatically eliminates fixation losses from your visual field testing.
Fixation losses due to low patient compliance are a major cause of unreliable visual fields. Tighten the three. Allen head screws again. A complete rotation around the column is blocked by a built in limit. Place the instrument on the table so that the opening of the table foot and the headrest are in the same direction.
Connect the patient response button to the connector located on the support of the headrest. Stick the connector plug so far into the connector housing that the catches audibly click. To remove the patient response. Plug the power cord in.

Do not use the forehead rest of the perimeter as a carrying handle. This plastic part is not adequate for the weight and can be thus broken. They vary in importance and should help preclude risks for the patient and operator, hinder damage to the perimeter and insure optimal functioning. TIP: Tip for insuring optimal functioning of the perimeter. Some functions are offered as options and may not be implemented or accessible in your instrument.
