The device must be placed in a room which is not exposed to adverse chemical-
physical conditions, such as the presence of sulfur, salt, dust, direct sunlight, lack
of ventilation, high humidity, sudden temperature drops or peaks. The safety
and/or effectiveness of the instrument cannot be guaranteed if these conditions
are not met.
The following precautions are important to avoid incorrect use of the device:
❖
Provide explanations to patients before placing them in front of the device.
❖
Use the device in dim light, or at least away from direct light. This will facilitate the
natural dilation of the pupil.
❖
The minimum pupil diameter required to obtain good quality images is 2.5 mm.
❖
If the patient does not fix correctly and steadily, the images acquired may relate
to portions of retina that are not what is expected.
