CAUTION

CAUTION

Note:

Since the upper part and lower part of the instrument are connected only by the power cable, take them out together so they do not separate from each other.

Always install the instrument on a fixed, stable surface, to prevent damage or injury.

The instrument should always be carried by two people, both holding the bottom of the instrument. Attempting to carry the instrument alone could result in backache or other injury. Attempting to carry the instrument without holding it at the bottom could result in injury or damage.


1 Remove the instrument body (1) from the container and place it on the appropriate table. 2 Slightly raise the omni-directional joystick, and pull out the cushion from the lower part of the base in the direction of the arrow.

If dilation is insufficient, you can change the flash level to twice the set value with the illumination aperture switch (40)*. When the illumination aperture switch (40) is pressed, the flash level compensation display appears on the color video monitor, indicating that the flash level is now twice the set value. Pressing the illumination aperture switch (40) again, returns the flash level to the set value.

5 Bring the instrument slowly closer to the patient; the retina image appears on the video monitor.

6 Instruct the patient to look at the green light (internal fixation target). 7 While watching the image on the video monitor, adjust the brightness of the image using the illumination level switch (38).Note: For details about mapping data printing, see Setting illumination level on page 65. If the illumination level is too bright, the split lines will be difficult to see.

8 Bring the instrument still closer to the patient; and two bright spots for the working distance alignment will become visible.

9 Using the joystick, bring the two bright spots together on the video monitor.

10 Using the joystick, move the instrument body until the bright spot of the video monitor moves into the ( ) scale.

11 Operating the focusing knob, align the focusing split lines into one line on the video monitor.

Split lines

Note:

If the split lines cannot be aligned using the focusing knob, change the diopter compensation lens. For details, see Changing the diopter compensation lens on page 67. Because split lines are inactive when the diopter compensation lens is other than (0), turn the focusing knob so the eyeground image is clearly visible on the color video monitor. If the split lines are not clearly visible, lower the illumination level, or lower the brightness of the color video monitor. For details about adjusting the brightness of the video monitor, see Adjusting the color video monitor on page 90. If one of the split lines cannot be seen, check if dilation is insufficient, or if the eyelashes or eyelid are shading the eye. You can remove split lines from the Monitor screen. Pressing the split switch (36) removes the split lines from the monitor screen. Pressing the split switch (36) again, displays the split lines on the monitor screen.

Note:

It is not possible to take an image while the xenon charging display is flickering on the color video monitor. Charging takes about 2 seconds. Wait until the xenon charging lamp turns on, for the next image.

13 The captured image is sent to the external recording device and displayed on the color video monitor.

Note:

If the image is insufficiently bright, you can compensate by pressing the flash level switch (37), and repeating the collimation and photography procedure.

74

Note:

The display of images on the color video monitor depends on the settings of the external recording device as well as those of the instrument.

Preparing the patient1 Apply mydriatics to the patients eyes, wait for thorough dilation, and then guide the patient to the photography room.

Note:

If picturing at a 45 picture angle or if there is insufficient dilation, photography is possible up to 3.7 mm pupil diameter by changing the stop using the illumination aperture switch (40).

The illumination aperture display appears on the color video monitor. 2 Seat the patient comfortably in the examination chair. See Positioning the patient on page 61. 3 Prepare for an intravenous injection of fluorescent contrast medium.

4.3.8

Collimation and photographyUse the omni-directional joystick to perform a collimating operation. For details about movement or adjustment of the instrument body using the omni-directional joystick, see Collimation and photography on page 68. 1 As all operations are identical to color photography up to the point of focusing, please refer to collimation of color photography. 2 Upon injecting fluorescent contrast medium, press the timer switch (41).

Note:

When the timer switch (41) is pressed, the timer begins to operate, and the buzzer sounds every 1 second for the first 20 seconds. Pressing the timer switch (41) again, will turn off the timer. The result of fluoro-photography depends on the injection time and the quantity of the fluorescent contrast medium used.

Note:

Fluoro-observationDo not continue visible fluoro-observation any longer than necessary to avoid any discomfort or injury to the patient.

CAUTION

Normally, observation is performed using infrared rays, but fluoro-observation of dynamic images can be performed using a color video monitor at the instant the fluorescent contrast medium begins to flow through the fundus artery.

Note:

The illumination level is automatically set to the maximum light intensity and the 6th and 7th steps of the illumination level display flicker on the color video monitor, indicating that the maximum light intensity is set.

2 Pull out the IR filter selector. The IR warning display disappears from the color video monitor.

3 It is possible to perform visible fluoro-observation on the video monitor.

78

Note:

Because the internal fixation target cannot be used when the fluoro-observation knob is on the visible side, instead use the external fixation target to guide the patient's eye. You can remove split lines from the Monitor screen. Pressing the split switch (36) removes the split lines from the Monitor screen. Pressing the split switch (36) again displays the split lines on the Monitor screen. During the visible fluoro-observation, observation TV camera settings are changed for visible fluoro-observation. In this case, as the TV camera gain is increased, images may become grainy.
