Goldmann Kinetic Perimetry

From Goldmann to Octopus

The Octopus 900 is the official successor to the original Haag-Streit Goldmann perimeter. It moves Goldmann perimetry into the computer age, allowing full support for medical records and much more.

  • Original Goldmann Cupola: For best comparability of test results, the  Octopus 900 uses the same spherical 30cm cupola as the original Goldmann perimeter.
  • Goldmann parameters: Stimulus size I..V, Goldmann intensities 1a..4e, manual and automated stimulus movement
  • Age matched normal values: For immediate judgement of normality
  • Repeatable tests: Automatic repetition and follow up of kinetic examinations
  • Quantification: Measurement of isopters for the quantification of progression
     

 

 
Goldmann Template with Age Matched Normal Values

When choosing a certain parameter set, like I3e, the age matched norms are superimposed to the Goldmann examination sheet as indication where testing is feasible. 

Sliders for Stimulus Size and Intensity

The Goldmann Kinetic Perimetry operating surface allows an experienced Goldmann orthoptist to become operational in a matter of minutes. Elements like stimulus size, intensity and the examination template are Goldmann alike.

 
Reaction Time Compensation

The Octopus GKP includes the patented reaction time compensation. It allows to test the patients reaction time and correct the given responses to receive more accurate, reproducible results. This is especially helpful when analyzing and comparing scotoma and isopter areas over time. On the left is an example of the blind spot with and without reaction time compensation of 300ms. 
Automatic Repetition of Kinetic Examinations

Now it is easier then ever to redo an individual kinetic examination. Just select the patient, click the “follow up” button and the test previously performed with this patient eye is automatically repeated. This allows even unexperienced examiners to perform follow up exams in kinetic perimetry. 
Manual and Automated Kinetic Testing

With the manual kinetic option you can move the light projector directly with the mouse or a pen display. The automated kinetic option allows to move the light projector with constant velocities and features programming individual tests.
Quantification of Isopter Areas

Isopter areas can automatically be quantified. This on one hand helps judging normality and on the other hand allows to observe changes over time.
