[Anterior eye observation screen - 4]
1. Cornea-reflected spots
When the anterior eye of the patient is displayed in the anterior eye observation screen, eight cornea-
reflected spots appear arranged in a circle. These cornea-reflected spots are used as a guideline for
alignment.
These spots are also used for detection of up, down, left, right, forward, and backward positions in the
auto tracking, and display of the electronic working dot and the working distance indicator.
2. Working distance indicator
Indicates the distance between the image capturing unit and the patient’s eye. Move the joystick in the
forward and backward directions so that only a single line of the working distance indictor is displayed. When
the alignment becomes optimum in all directions (up, down, left, right, forward, and backward) in the anterior
eye observation screen, the color of the indicator changes from light blue to yellow.
3. Target mark
Indicates detection condition of the cornea-reflected spots for alignment.
: Alignment condition is not detected.
: Alignment condition is detected.
When the alignment becomes optimum in all the directions (up, down, left, right, forward, and backward) in
the anterior eye observation, the color of the indicator changes from light blue to yellow.
4. Required pupil diameter mark
Indicates the required pupil diameter (pupil diameter required for proper image capture) in usual
photography mode.
In usual photography mode, the patient’s pupil diameter needs to be larger than this required pupil diameter
mark (4 mm in diameter). Check whether the pupil is larger than the required pupil diameter mark (4 mm-
diameter solid-line circle) in the anterior eye observation screen.
When the auto anti-misshooting is enabled , or if the cornea-reflected spots are not detected, or the
pupil edge is within the required pupil diameter mark, the required pupil diameter mark and the minimum
pupil diameter mark are displayed in pink. When the cornea-reflected spots are detected, the eyelid or
eyelashes are not detected, and the pupil satisfies the required size, the minimum pupil diameter mark is
displayed in green.
