8 Before Conducting the Examination
Instruction Manual Mesotest II (G/62800/0715/en) 21 / 86
Make sure that the viewer enclosure remains in contact with the
patient’s head during the entire examination. Interfering incidence
of light and impairment of the adaptation state associated with it
can thus be avoided.
8.2.1 Patient Adaptation
Before the examination, the patient’s eyes need about 5 minutes to adapt
to the darkness.
When the Mesotest II is set up in a darkened room, this is not a problem.
If the unit is set up in a bright room, adaptation of the patient must be
done by having him look into the unit for the required length of time prior
to starting the examination.
In a darkened room
Let the patient’s eyes adapt for about 5 minutes.
In a bright room
Let the patient look into the unit for about 5 minutes.
