User Manual AlgiScan 13
General use
The AlgiScan can be used with a large number of different practices and protocols. It
can be used on all patients without any age limit. It allows exact measurement of the pupillary
light reflex and the pupillary reflex dilation. Hence the user should take care to confirm these
two reflexes and their pertinence for every patient before using the AlgiScan.
It should be noted that in all cases, use of the appliance on the patient (with the
eye open) should not exceed 15 seconds continuously for the Tetanus, PPI and Flash modes.
For the PRD mode, the user starts the recording and stops it whenever needed. The maximum
recording time is 59sec. The number of measurements performed on the same patient should
not exceed 10 per hour.
Instantaneous measurement: an instantaneous measurement is a direct reading
of the pupil size by the user in real time on the AlgiScan screen.
Dynamic measurements consist of recording measurements under conditions
predefined by the user by selecting one of the available modes of the AlgiScan. This type of
measurement will then give a series of results with figures and a curve representing the
variation in the size of the pupil. Algiscan offers 4 different modes (Flash, Tetanus, PPI and
PRD).
Fitting the positioning eyecup
The AlgiScan has a silicone eyecup so it can be positioned on the patient’s face.
Before use, the practitioner must clean this part. For more information on cleaning, please
refer to the chapter “CLEANING and DISINFECTION”. This eyecup is the only part in contact with
the patient. The eyecup is to be placed on the AlgiScan by simply pushing it onto the black
lens.

Installation and positioning of the AlgiScan
The correct positioning of the AlgiScan in relation to the filmed eye of the patient
enables more accurate measurements to be obtained. The black silicone end-piece on the
AlgiScan must be in contact with the upper and lower part of the eye socket bone without
pressing. In this way there will never be any pressure on the eye-ball itself. The appliance
should be held vertically and firmly so that it does not move in relation to the patient‘s head.
