(a) Goldmann results
(b) Octopus results
Figure 5: Nonidentical/dissimilar unmatched results (left eye only). Patient with right homonymous hemianopia showing a matching visual field result for the right eye on both Goldmann kinetic perimetry and Octopus semiautomated perimetry. The Goldmann result for the left eye shows the right-sided hemianopia. However, the Octopus result for the left eye does not show the defect. Although the patient maintained good central fixation, the Octopus result was felt to be due to false positive responses.
