OPERATING PROCEDURE : Photography Mode Other Than Normal Photography Mode
2.5 Photography Mode Other Than Normal Photography Mode
This section explains the image capture procedure in modes other than Normal photography mode:
Stereo photography mode, Panorama photography mode, Anterior eye photography mode, Small pupil
photography mode, and Low-light photography mode.
2.5.1 Stereo photography mode
This mode is used to capture two fundus images: one at about 1 mm away to the temporal side from the
fundus center, and the other at about 1 mm away to the nasal side from the fundus center. (The electronic
working dot automatically moves to the shifted position.)
The two captured images are saved as a set and can be viewed stereoscopically using the special stereo
viewer (optional accessory to NAVIS-EX).
Refer to the NAVIS-EX Operator’s Manual for the method of the stereoscopic viewing of the image.
Setting for Stereo photography mode
Control menu: Photography settings—Photography Modes, STEREO—ON (default)
For details of setting, see “
 Photography modes” (Page 111).
The operating procedure below is explained in Stereo photography mode using the auto shot without the
blink detector that is the default setting.
The image capture procedure is basically the same as “2.3 Image Capture (Normal Photography
Mode [Auto shot, No blink])” (Page 58) except that two horizontally shifted images are captured.
In Stereo photography mode, the first capture image is a temporal image and the second is a nasal
image.
1
Prepare the patient for image capture.
The left eye is used for the explanation.
2
Press the Stereo photography button to switch to Stereo photography mode.
3
Perform alignment using the joystick so that the anterior eye is displayed in the screen.
4
Adjust the joystick until the (eight) cornea-reflected spots appear.
When the eight cornea-reflected spots are detected, the image capture procedure is auto-
matically advanced in the order as described below.
1) The auto tracking in the up, down, left, right forward, and backward directions is acti-
vated.
2) The electronic working dot (light blue) is displayed at a position shifted from the center to
the right (about 1 mm toward the temporal side of the left eye) for the target mark to
adjust to that position to enable stereo photography.
3) The working distance indicator is reduced to a single line and alignment is complete.
When alignment is complete, the auto focus icon appears, then the fundus observation
screen is automatically displayed. In the fundus observation screen, the optical working dot
charts disappear and the stereo gauge (blue) is displayed.
