Example of a result: “PRD”
After the values measured the AlgiScan displays a comment about the intensity of
the dilatation reflex (here the comment is “Very Strong”; it is highlighted in red).
The comment displayed and its highlighting colour is obtained via the quantitative
and qualitative scale of the dilatation reflex explained below.
Qualitative/Quantitative scale of the Pupillary Reflex Dilation (4 levels, 3 colours)
The value taken into account for the qualitative/quantitative scale of the Pupillary Reflex
Dilation and for the display of the comment is the amplitude of the reflex (value as a
percentage). They are only indicative and must be corroborated with other physiological
indicators commonly used.

Results in the “PPI” mode
In this mode, the results displayed after record are:
• The recording monitoring curve with the following markers:
o The different levels of electric stimulation by color bands (light blue and light green)
and the value of stimulus
o Pupil diameter baseline (blue horizontal line)
o Maximal size variation of the pupil size (black horizontal line)
• The baseline diameter before stimulation (baseline in mm)
• The percentage pupil’s variation obtained (Var. in %)
(Var. %=((Max.-Min.)/Min.*100).
• Maximal size variation of the pupil (value in mm in brackets)
• PPI score
