Bevers C, Blanckaert G, Van Keer K, Fils J, Vandewalle E, Stalmans I. Semi-automated kinetic perimetry: Comparison of the Octopus 900 and Humphrey visual field analyzer 3 versus Goldmann perimetry…
Where can I find perimetry charts? If I buy an Octopus perimeter will I lose my old HFA data? How does the Octopus perimeter compare to the Manual Goldmann? What tests can I do on an Octopus perimeter? What size is the cupola on the Octopus 900? What print-outs are available on the Octopus and can it print in a Humphrey-style format?
Goldmann kinetic and Humphrey static perimetry results are not amenable to quantitative comparisons because of the different formats of data produced by each device. The Goldmann perimeter produces a circular isopter on a polar coordinate grid and the Humphrey perimeter produces a discreet grid of logarithmic sensitivities with x-y coordinates ( Figure 1 ).

Reference in perimetry right up to today – Goldmann Kinetic perimetryIn 1945, Professor Hans Goldmann of the University of Berne developed, together with Haa RESULTS. Bilateral examination time for Goldmann fields was 10 +/- 2 minutes and for Humphrey fields was 50 +/- 10 minutes (P<.001, n = 12). Superior fields at the 12:00 meridian were 46 degrees +/- 6 degrees taped, and 28 degrees +/- 12 degrees untaped for Goldmann perimetry (P<.001), and 38 degrees +/- 8 degrees taped, and 24 degrees +/- 12 degrees untaped for Humphrey perimetry P<.001).

Main outcome measures included efficiency, patient preference, and sensitivity in detecting visual field loss Perimetry is the systematic measurement of visual field function (the total area where objects can be seen in the peripheral vision while the eye is focused on a central point). The two most commonly used types of perimetry are Goldmann kinetic perimetry and threshold static automated perimetry.

Design: Prospective consecutive comparative case series. The light may move towards the center from the perimeter (kinetic perimetry), or it may remain in one location (static perimetry). The Goldmann method is able to test the entire range of peripheral vision, and has been used for years to follow vision changes in glaucoma patients. However, now automated perimetry is more commonly used.

The Goldmann Visual Field test is a very important diagnostic tool in advanced glaucoma and in conditions such as in Cerebrovascular Accident (CVA). A CVA is
Introduction Since its introduction in 1945, the use of a manual Goldmann perimeter has been the method of choice to perform kinetic perimetry. 2015-05-31 · interpretation of Humphrey perimetry. Kinetic perimetry uses a moving illumi-nated target and is done either manually (eg, Goldmann) or on an automated machine (eg, Octopus). Goldmann machines are no longer manufactured, being slowly replaced by Octopus machines. Nevertheless, Goldmann remains the most commonly used kinetic Hans Goldmann of Bern devised a hemispheric bowl, with a self-illuminated, projection perimeter, in 1945, in which fixation, retinal adaptation, and stimulus size and intensity could be precisely controlled. The visual field could be readily recorded by means of an ingenious pantograph. To evaluate the clinical usefulness and reproducibility of (semi‐)automated kinetic perimetry of the Octopus 900 and Humphrey field analyzer 3 (HFA3) compared to Goldmann perimetry as reference technique.
