Early diagnosis and standard white-on-white perimetry in one device

The Octopus 600 extends the successful Haag-Streit product range of visual field analyzers, combining the Pulsar method for early glaucoma detection and standard white-on-white perimetry for long term followup in a single compact, standalone device.

 

Fast and reliable Pulsar test method for early glaucoma detection

Various studies over the past decades have shown that contrast sensitivity and flicker sensitivity are affected in glaucoma. The Pulsar method combines both by presenting a contrast-modulated ring target that flickers at 10 Hz in counterphase, resulting in the method of choice for early glaucoma detection.

Expert in early glaucoma detection and follow-up

With the Octopus 600, Haag-Streit has introduced a new perimetry technology that makes use of a TFT-based monitor to produce stimuli and background. This allows the instrument to display complex stimuli such as Pulsar, which would otherwise not be possible with cupola-based or projection type perimeters. Combining both Pulsar early glaucoma detection and standard white-on-white perimetry, the instrument is capable of covering the most important stages of disease progression, allowing for early diagnosis and follow-up.

Early glaucoma detection made easy

Pulsar is a patented flicker stimulus, displaying a ring pattern with different contrast levels in counterphase. As independent studies confirm, the test is easy – even pleasant – to take, while being both sensitive and specific in the detection of early glaucoma. Unlike other early diagnostic methods, that challenge the patient with hardto-distinguish answering criteria, Pulsar requires no more than a simple click for every target that appears. Combined with our proven TOP fast-thresholding strategy, the Pulsar examination method delivers fast and reliable results.

STANDARD WHITE-ON-WHITE PERIMETRY For long term follow-up

Standard white-on-white perimetry is the preferred method for long term follow-up in glaucoma and various other pathologies. The Octopus 600 is the first perimeter that performs standard perimetry on a flicker-free screen, using TFT technology. A dynamic range similar to that of projection type perimeters is achieved by dynamically increasing the stimulus size from Goldmann III up to Goldmann VI, after reaching maximum screen luminance2 . Furthermore, this principle makes use of the improved repeatability which larger stimuli have in zones of advanced pathology3 .

Large trial lenses

Trial lenses for spherical corrections between –8 dpt and +4 dpt can be placed in one of the trial lens compartments on either side of the instrument. The trial lenses are significantly larger than those of previous instruments, in order to facilitate the positioning of the patient, and magnetic for easy placement.

New patient response button

The ergonomic response button fits nicely in the patient’s hand and is easy to use even for patients with arthritis. In addition, the button has been redesigned to create an improved audible and mechanical feedback.

Ergonomic design

Ample space and the adjustable forehead rest allow examined patients to wear their own glasses. The shielded side view prevents the patient from being distracted.

Correction for presbyopia

The instrument is equipped with a built-in +3.25 dpt correction lens for presbyopia, so age correction is no longer necessary. It also allows testing with the patient’s own glasses.

It fits anywhere

The Octopus 600 has a small, compact design allowing for a minimal footprint. Add in silent operation with no fans or motors and you have a perimeter that can be placed anywhere in your office. The few clicks needed to operate the perimeter can easily be done at the side by the receptionist.

CLUSTER ANALYSIS Providing meaningful results

Cluster analysis combines high sensitivity with good specificity. Test locations are grouped (clustered) along nerve fiber bundles to better analyze changes in crucial areas like the nasal step or the macula. This eliminates the time-consuming method of counting isolated points. A combined probability/deviation graph highlights pathologic regions.

POLAR GRAPH Combining structure and function

Combining the results of both structure and function (A) is key in obtaining a comprehensive assessment for the onset and progression of Glaucoma. With the Octopus Polar Graph the nerve fiber bundles that are in danger or defective are easily identified. Local defects are represented as red lines and projected along the nerve fibers to the optic disc (B). The projected defects (C, D) are vertically mirrored and scaled with rings for 10, 20 and 30 dB deviation (E). The Octopus Polar Graph allows for direct comparison with structural (F) findings.

VARIOUS PRINTOUTS Intuitive interpretation of visual field results

Configure your favorite printout and graphics representation to reduce the time necessary to interpret the results. Choose either the proven Octopus 7-in-1 printout containing the cumulative defect curve (Bebie curve) or the HFA style printout. Furthermore, the 4-in-1 printout or the series report can be customized as well. Don’t want a paper copy? Save the report as an image or PDF and view it on your screen or export it to your electronic medical record (EMR) system.

TOP FAST-THRESHOLDING STRATEGY Increased efficiency

Tendency oriented perimetry (TOP) presents the maximum in fast threshold testing by reducing the examination time by nearly 80% to just over two minutes compared to 6–8 minutes (Dynamic strategy) or 10–12 minutes (Normal strategy). The TOP algorithm is a systematic method which takes into account correlation of the threshold values in neighboring locations. As the Pulsar method exclusively uses the TOP fast-thresholding strategy, the Octopus Program Gp (Glaucoma, 59 test locations, central 30°) can be completed within 2–4 minutes.
