5.1 Function
The optional accessory GLOW800 enables the surgeon to excite and
observe Near Infrared (NIR) fluorescence (FL) of the fluorophore
(ICG) with the surgical microscopes M530 OH6, M530OHX or ARveo.
When activating the GLOW800 mode, the white light illumination of
the Leica microscope stand (Leica OH6, Leica OHX or ARveo) is
extended to InfraRed (IR) to excite the fluorophore (ICG).
The filtered NIR fluorescence signal of the fluorophore (ICG) is
acquired by a NIR sensitive video camera in the GLOW800 ULT and
processed in the GLOW800 VPU.
5.1.1 Fluorescence observation on the microscope
video monitor
GLOW800 offers two different types to observe the fluorescence
video signal on the optional microscope video monitor:
Type A: Pseudocolor mode (Pseudocolor ON)
White light object view with the embedded fluorescence signal in
pseudocolor, Video #1A
Black&White fluorescence view Video#2A
Type B: Black&White Mode (Pseudocolor OFF)
White light object view #1B
Black&White fluorescence view Video#2B

Description

5.1.2 Fluorescence observation and recording with a documentation system
The GLOW800 VPU generates two videos which can be recorded by an optional documentation system, e. g. HDMDPRO, if integrated into
the surgical microscope.
The following recording and visualization settings can be predefined on an optional documentation system. The records and displays are
done in the following way:
White light fluorescence type A: Pseudocolor mode (Pseudocolor On – WL/FL) and b/w fluorescence observation (B/W-FL)

With the optional HDMD Pro recording system activating and deactivating the GLOW800 will automatically start and stop the recording of
the two predefined video streams. If the recording of the white light mode is already running, the recording will switch to record the two
predefined video streams ("Loop WL and "Loop NIR"). Several "Loop" recordings and WL recordings (segments) can be differentiated by an
index in the video review page. If the GLOW800 mode is ended, both records will end as well.
Note
If the white light record should proceed after the GLOW mode it has to be started again.
The play back function of the optional HDMD PRO documentation system allows to display again any of the "loops" on the screen, once or
steadily, in normal, slow or frame-by-frame motion. The second recorded video can be selected for play back as well, either as the main
video source or as a picture-in-picture (PiP) or side-by-side (SbS).
Please refer to the documentation device manuals for further information.

7.2 Fluorescence visibility
The GLOW800 function optimizes automatically the fluorescence
visibility to receive the best possible image for a broad working
range of microscope parameters and ICG dosage.
However, these parameters still have an impact to the fluorescence
visibility as the following description explains for further
optimizations.
FL Visibility = Illumination × Dosage
Mag2× WD2
FL Visibility: Fluorescence brightness/perceptibility on the
screen
Illumination: Microscope Excitation intensity
Dosage: Injected ICG amount in mg/kg
Mag.: Magnification
WD: Working Distance
The ICG Dosage is the anesthetist's and/or surgeon's
decision.
• Less excitation intensity “Brightness GLOW800” and/or a lower
ICG dosage reduces the fluorescence visibility, especially at high
magnification and/or long working distance. Less fluorescence
visibility or fluorescence brightness might be observed already
at a lower magnification and WDs.
• Higher excitation intensity “Brightness GLOW800” and/or a
higher ICG dosage increases the fluorescence visibility,
especially at high magnification and/or long working distance
and can compensate the reduction of these two optical
parameters.
The fluorescence visibility can decrease even with standard
conditions, if the efficiency of the illumination system is
reduced or the Xenon bulb life time reaches its end.
In this case a message is displayed on the graphical user interface
(GUI) with a request to change the illumination bulb.
7.2.1 GLOW800 Brightness (Illumination/
Excitation intensity)
 Open the "FL" tab to set the GLOW800 brightness to the
required level with bar (1).
1
Recommended Brightness settings
The default and recommended "Brightness GLOW800" setting is
100% to achieve good fluorescence visibility in higher
magnifications and working distances.
7.2.2 Working distance limitation
10
 Decide if the working distance limitation in white light mode
should be switched on (default) or off (10).
When the working distance limitation in white light mode is
switched off and the working distance is above the limit
when switching to GLOW800 mode, the working distance
will be reduced and the picture will get out of focus.

Preparation before surgery
14 GLOW800 / Ref. 10 747 241 / Version 04
7.2.3 GLOW800 Limits
The "GLOW800 Limits" define Magnification and Working Distance
ranges for good fluorescence visibility.
To extend the Magnification and/or Working Distance range(s) you
have to confirm that you may have to adjust the ICG dosage to get
optimal fluorescence visualization.
7.3 GLOW800 User Setting Menu
The tab offers specific GLOW800 settings for each user:

7.3.1 Pseudocolor
Pseudocolor defines one of two types of fluorescence observation.
Pseudocolor can be switched On or Off with button (1).
Default is on.
Pseudocolor on (Observation type A-1 to A-4)
• White light object view with the embedded fluorescence signal
in pseudocolor (white light fluorescence observation = WL/FL)
Pseudocolor off (Observation type B-5)
• Standard Black&White fluorescence view = B/W-FL on the
microscope monitor.
See as well Chapter 5.1.1.

7.3.2 Threshold
With the «Threshold» bar (2, page 14) the fluorescence intensity range to be displayed in the white light fluorescence view can be
defined. Low intensity signals (e.g. noise) and/or high intensity signals can be filtered out by defining a lower and an upper threshold with
the two red bars.
The default value and recommended setting for the lower threshold is 0%, for the upper threshold 100% to observe the full range of
fluorescence signals. Using the test card demonstrates how the «Threshold» function influences the fluorescence signal.
Lower Threshold at 0% and and upper Threshold at 100%- all fluorescence intensities are displayed

Threshold defines the indicated fluorescence range by the lowest indicated fluorescence intensity (1= Down, 2=Up) and the highest
fluorescence intensity (5= Down, 6=Up). The red bars (3) indicate the stored values, the grey bars (4) the displayed fluorescence range. The
percentages of the lower and upper limit of the range are given by the values (7) and (8).
Default is the display of the full fluorescence range with a lower limit = 0% and upper limit = 100%.
In case of adaptation of the range by the buttons (1), (2), (5) and (6) the bar will indicate the adjusted range. The new range can be
activated by the «Apply» button (7, page 14) to observe the results on the screen and eyepieces (with optional CaptiView). If the new
range is saved the red bars will move to the appriate positions in the graphics; example: 32–72% range.

7.3.3 Color
With «Color» button (3, page 14) the pseudocolor of the fluorescence signal can be chosen.
Selectable color values are from 1=magenta to 7=chartreuse, if the FL image is not injected into the eyepiece(s). The chosen color defines
the appearance of the fluorescence on top of the white light image to optimize the color contrast between the colors of the object in white
light and the fluorescence signal.
If the GLOW800 image is injected in the left or both eyepieces by use of the optional CaptiView module (chapter 7.7), the choice of
colors is reduced to blue #3 and green #6.

7.3.4 Intensity
«Intensity» bar (4, page 14) adjusts the fluorescence contrast,
brightness and transparency in relation to the object details.
The intensity values range from 0% to 100%, default is 50%.
Fluorescence is visible across the full percentage range.
E.g. at 0% intensity fluorescence is just visible with the object
dominant, at 100% intensity fluorescence is intensively visible and
dominant.
Minimum intensity setting – 0%
Medium intensity setting – 50%
Maximum intensity setting – 100%
7.3.5 WL Saturation and WL Brightness
To increase the contrast of the fluorescence information in relation
to the anatomical video image the characteristics of the white light
anatomical image can be adapted by:
• Reduction of the white light anatomical image color saturation
with the WL Saturation bar (5, page 14)
• Reduction of the white light anatomical image brightness with
the WL Brightness bar (6, page 14)
7.3.6 Apply button
By pressing the "Apply" button (7, page 14) on the GLOW800
page of the user settings changes of one or more of the different
GLOW800 settings become active in the GLOW800 system.
The result of the changed settings can be observed after a few
seconds on the GLOW800 screen.
