OCTOPUS 900

The Most Versatile 90° Full Field Perimeter for Static- and Kinetic Perimetry

It incorporates standard White-on-White and Blue-on-Yellow static perimetry.

With an optional software program, the OCTOPUS 900 can be upgraded to perform true Goldmann kinetic perimetry.

The OCTOPUS 900 covers all the needs in clinics and in scientific applications without limitation.

Reliable Precision

• 100% eye fixation control – if fixation is lost, no stimulus is presented.
• Diagnostic programs with test stages prioritising the most crucial field areas.
• Optional fast software for significantly shorter examinations avoid errors caused by patient and retinal fatigue.
• Automated pupil measurement allowing accurate assessment and comparison of data.

Speed and Ease of Use

• Separate examination- and PC control unit allows the technician to work comfortably in ambient light conditions.
• Offers the most complete library of standard diagnostic programs and test strategies.
• With the Tendency Oriented Perimetry (TOP) test strategy, a full threshold examination takes less than 2:30 min.
• The clear Seven-in-One print-out presents the most complete information needed for the assessment of the results.
• During the examination, a real time display of statistical data provides on-line information about the status of the patient’s visual field. Also, the test procedure can be interrupted at any time and continued later without losing data.
• Flexible and user defined test parameter settings for additional custom test programs serving scientific studies.
• Network compatible – allowing examination results to be viewed on more than one monitor.
• Software is easily upgradeable to the latest version by downloading the software from Internet.

Patient Comfort

• The instrument table offers ample legroom and access for any type of wheel chair.
• The spherical Goldmann bowl ensures accurate static and kinetic perimetry to 90° periphery.
• Faster testing results in better patient cooperation.
• Patients are encouraged to blink regularly without the risk of introducing erroneous results.
• Seated separately from the control unit allows the patient to work in a more quiet environment.

Goldmann Kinetic Perimetry*

• Choice of stimulus sizes I through V in any combination of stimulus intensities <1> through <4> (0.5 log units) and <a> through <e> (0.1 log units)
• Selection of stimulus travel speed from 0°/s (static) or 2°/s to 10°/s
• Complete freedom in choosing start and end points of kinetic stimuli (vectors)
• Manual and automatic operation
• Features as age related normal values, reaction time correction and isopter area quantifcation
