Visual field tests Vi s ual fi el d t es t s The following visual field tests are available with the Henson 9000 Multiple Stimulus Supra-Thresho ld Choose this if speed is important. It is approximately twice as fast as the Single Stimulus supra- threshold strategy in patients with little or no defect.

The perimetrist then marks the location (s) they missed. The perimetrist should then alter the supra-threshold increment in order to measure the depth of the defect. © 2017 Elektron Technology...
Page 37: Analysing The Results
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 41: Blind Spot
Visual field tests Blin d s p o t 3 .2 .1 At the beginning of a ZATA test the Henson 9000 searches for the eye's blind spot. It starts off by presenting a Supra-Threshold stimulus at the most likely location of the blind spot.

Page 78 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...
