5-1 LCD monitoring mode (“Mydriatic color” and “FA” mode)
This paragraph describes the method of performing mydriatic photography watching LCD monitor instead of looking
into viewfinder as if doing non-mydriatic photography. This feature allows you to photograph without diopter adjust-
ment. Also a patient becomes free from dazzling observation light since it uses infrared light in the mydriatic color
mode and reduces the intensity of observation light in the mydriatic fluorescein mode. Therefore you can photo-
graph smoothly.
1) Select “Color” by the mode select button on the right-hand panel.
2) Press “LCD monitoring” button on the right-hand panel.
The LCD monitoring will start with operating sound while the observation light
turns infrared light.
3) From now on, operate according to the paragraph of “3-2 Non-mydriatic
photography.”
Starting with the step 2), you can photograph as if doing non-mydriatic
photography.
n
In LCD monitoring mode, you can perform non-mydriatic photographing at a field angle of 50° of the exam-
ined eye the pupil of which can be spontaneously dilated to 5.5 mm or so in diameter, without applying my-
driatic eye drops to it.(non-mydriatic photography at a field angle of 50°.)
n
In LCD monitoring mode, observe and alignment the examined eye with infrared light as in the case of
non-mydriatic photography. Thus, because the patient can be free from dazzling observation light, you can
smoothly perform photography for the patient even if not accustomed to dilating the pupil.
Non-mydriatic photography
at a field angle of 50° will be
enabled if the pupil can be
spontaneously dilated to 5.5
mm or more in diameter
• Unlike observation through viewfinder, accurate states of flare and focusing will become hard to check for.
• When observing on LCD monitor, bear in mind that, unlike an actual picture image taken, both a fluorescein
angiogram and a normal fundus picture image will appear on the monitor. (Picture image taken will be
limited to fluorescein angiogram.)
