Prepare the patient for image capture.
1) If the patient is wearing contact lenses, instruct them to remove them.
2) Have the patient seat themselves in the chair in front of the device.
3) Clean the parts that come into contact with the patient (chinrest and forehead rest).
Use a gauze or absorbent cotton swab dampened with rubbing alcohol.
If chinrest papers are used, remove a sheet after each patient.
4) Have the patient rest their chin on the chinrest and their forehead on the forehead rest
securely.
If the patient is not in a comfortable posture, adjust the height of the table and chair.
5) Inform the patient that the chinrest is going to be moved up and down, then adjust the
chinrest height by the chinrest up/down buttons so that the patient’s eyes are roughly
level with the eye level marker.
6) Instruct the patient to gaze at a green blinking light in the device when it becomes visible.
7) Instruct the patient to open both of their eyes wide during image capture.
If one eye is closed, proper eye fixation cannot be achieved, and the other eye cannot be opened
wide enough.
8) Instruct the patient not to blink during image capture.
• If eye fixation is difficult (for reasons such as inability to see the internal fixation lamp), use
the external fixation lamp, and instruct the patient to look at the blinking external fixation
lamp with the other eye.
• If eye fixation cannot be achieved with either the internal or external fixation lamps, instruct
the patient where to look until fixation is achieved.
Example—“Look straight. Slowly move your eyes to the right.”
• If it is difficult for the patient to keep their eyes opened without blinking, use the auto shot
with the blink detector. For details, see “2.6.2 Auto shot” (Page 80).
Doing so not only helps the patient, but also facilitates image capture.
