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