OPERATING PROCEDURE
:
Photography Mode Other Than Normal Photography Mode
2.5.4
Small pupil photography mode
If the patient’s pupil is smaller than the required size (4.0 mm in diameter) but satisfies the minimum pupil
size (3.3 mm in diameter), perform image capture in this mode. (Available in Normal, Stereo, and Panorama
photography modes)
Setting for Small pupil photography mode
Control menu: Photography settings—Photography Modes, Small Pupil—ON (default)
When this mode is used (ON), the small pupil photography button
is displayed in the screen. (When it is not
used (OFF), the button is not displayed.)
Additional setting for Small pupil photography mode
Control menu: Photography settings—Photography options, Auto switch to SP photography mode—OFF (default)
When this function is enabled (ON), the device automatically detects whether the patient’s pupil size satisfies the
required pupil size and enters or exits Small pupil photography mode. Even when the setting is OFF, Small pupil
photography mode can be enabled also by pressing the small pupil photography button. (When the “Auto switch to
SP photography mode” function is ON and the small pupil photography button is pressed, the device exits Small
pupil photography mode in about three seconds if the patient’s pupil size satisfies the required pupil size.)
Control menu: Photography settings—Photography options, Light level in SP photography mode—0 (zero) (default)
In general the fundus image becomes dark in Small pupil photography mode. To capture images bright enough in
Small pupil photography mode, the device increases the flash intensity three levels higher in Small pupil
photography mode than in Normal photography mode. To capture darker images, the flash intensity can be reduced
from 0 down to a minimum of
−
3.
For details of setting, see “
Photography modes (page 111)” and “
Photography options (page 113)”.
The procedure is the same as “2.3 Image Capture (Normal Photography Mode [Auto shot, No blink])” (Page
58) except for Steps 3, 4, and 7.
1
Perform Steps 1 to 4 of the “2.3.1 Image Capture with auto shot” (Page 58) and perform
alignment using the joystick so that the anterior eye is displayed in the screen.
2
Perform either of the two steps below in accordance with the setting.
1) When the “Auto switch to SP photography mode” setting is OFF, press the small pupil
photography button
if the patient’s pupil does not satisfy the required pupil diame-
ter in the anterior eye observation screen (with the pupil edge in contact with the required
pupil diameter mark and the required pupil diameter detection mark displayed as
).
The small pupil photography button
changes from black to orange, and the device enters
Small pupil photography mode.
2) When the “Auto switch to SP photography mode” setting is ON, if the patient’s pupil does
not satisfy the required pupil diameter, the device automatically enters Small pupil pho-
tography mode.
• In images captured in Small pupil photography mode, flare may be captured outside the
image capture range mark.
• If the patient’s pupil is smaller than the minimum pupil size (3.3 mm in diameter), proper
images cannot be captured. In such a case, darken the room to make the pupil larger. If
that does not enlarge the pupil enough, consider using mydriatics under the direction of a
doctor.
