title: [Pupil perimetry with the Octopus 1-2-3. Initial experiences].
abstract: OBJECTIVE
  Development of a clinically useful pupil perimetry on an OCTOPUS 1-2-3.
  
  
  METHODS
  Various test parameters were investigated on a moderately modified OCTOPUS 1-2-3. We evaluated the pupillary responses of 122 eyes of 122 healthy volunteers qualitatively.
  
  
  RESULTS
  Pleasing pupillary responses were obtained with the following parameters: 200 ms stimuli, Goldmann size 5 (1.5 degrees), background illumination 3 apostilb. Acoustic signals 0.5 seconds before stimulus presentation were helpful to minimize blinking artifacts. The pupillary reactions were fare stronger in central areas of the visual field than in mid-peripheral areas (i.e. 26 degrees).
  
  
  CONCLUSIONS
  Pupil perimetry can be preformed on a moderately modified OCTOPUS 1-2-3. The results reveal considerable inter- and intra-individual variability. Equal pupillary responses at all eccentricities would improve subsequent mathematical evaluation.
