  • Title: [Pupil perimetry with the Octopus 1-2-3. Initial experiences].
    Author: Turtschi S, Bergamin O, Dubler B, Schötzau A, Zulauf M.
    Journal: Klin Monbl Augenheilkd; 1994 May; 204(5):398-9. PubMed ID: 8051881.
    Abstract:
    PURPOSE: Development of a clinically useful pupil perimetry on an OCTOPUS 1-2-3. MATERIALS AND 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.
