It is approximately twice as fast as the Single Stimulus supra- threshold strategy in patients with little or no defect.
Page 23 Visual field tests Supra- t hreshold t est s There are two different supra-threshold tests provided with the Henson 8000 software, single multiple stimulus: Both incorporate several levels of testing. Both can be run in an age-related or threshold-related mode.

This calculation is based on a scoring system applied to the visual field data. The score increases with the number, depth and clustering of any missed stimuli. The score is then compared to a normal database of scores to derive a probability value. © 2017 Elektron Technology...

Page 70 It is important that the patient fully understands what they need to do during the test. Suggested instructions for the different tests can be found by following the links below: Multiple stimulus supra-threshold Single stimulus supra-threshold ZATA Drivers © 2017 Elektron Technology...
Page 71 It is important that the patient wears the correct refractive correction (suitable for a 25cm test distance) during the visual field test. The Henson 8000/9000 is designed to be used with a special perimetric lens set. This uses large diameter lenses, which attach to a special frame. This set overcomes the problem of lens rim artifacts that are common when trial case lenses are used with a lens holder attached to the perimeter.

Page 73 Perimetrists can provide a more accurate estimate of the patient's reliability by simply observing them during the test. Perimetrists should, therefore, be encouraged to make comments on the visual field chart concerning the reliability of the result, e.g. Fixation excellent, Fixation poor etc. © 2017 Elektron Technology...
Page 74 If the first eye was OK and the second eye showed up a defect then it is possible to go back to the first eye and test some more locations now that the suspicion of a defect has been raised by the result from the second eye. © 2017 Elektron Technology...
Page 75 It is a good idea to tell the patient not to be concerned if they make some errors at the beginning of the test as the first first few presentations do not count. If further demonstration is required then the perimetrist should stop the test and start again after re-instructing the patient. © 2017 Elektron Technology...
