Chapter 1 - Warnings and cautions
CAUTION
Day to day use - operators
The protection provided by the equipment may be impaired if the equipment is used in a
manner
NOT
specified by Optos.
The use of this device or any other device which uses light for ocular examination should
NOT
be prolonged unnecessarily.
Do
NOT
place any optical elements, with the exception of the patient wearing contact
lenses, between the device and the patient’s eye.
Do
NOT
use lint cloths, tissues, or other materials that may create dust, on or near the
scan head. Always allow cleaned areas to air-dry.
The device requires low levels of room light to operate efficiently. Take care to avoid
accidents when working under low light conditions.
Do NOT touch the air vents.
Only use the fabric cover when the scan head is powered
OFF
or in standby mode.
Remove the fabric cover before operating the scan head.
Measurements on Optos UWF
opto
map and OCT images are based on scale factors
derived from the wide-angle schematic eye model published by
Navarro et al
1.
. This
model describes a spherical 24mm representation and is embodied into the DICOM
encoding Supplement 173: Wide Field Ophthalmic Photography Image Storage SOP
Classes.
Measurements in third party viewers may not be accurate.
CAUTION
Day to day use - patients
Patients
MUST NOT
operate this device.
The patient should not touch the touch screen. The patient should only be in contact with
the forehead pad, chin pad and face pad.
When angiography images are being captured additional space will be required to allow
the injection of the dye and for other individuals involved in the procedure. These
individuals could include medical staff or patient helper.
Do
NOT
inject the patient until the appropriate point in the angiography procedure.
Do
NOT
capture images when the face pad is
NOT
in place.
Do
NOT
lean on the head rest, chin rest or table.
Ensure the head rest or chin rest do
NOT
restrict the patient’s access to the device.
The face pad may get warm during use.
The scan head will move when the alignment system is being centered. This will happen
automatically when the device is switched
ON
and when the alignment system is re-
centered between patient sessions. You should ensure that there is space around the
scan head to allow free movement.
