1.5
Contraindications
Absolute contraindications
There are no known absolute contraindications for the use of
SPECTRALIS for diagnostic imaging.
When using fluorescence dyes, follow the instructions given on the
contrast agent package insert.
Relative contraindications
Photosensitive Epilepsy
While no such event was reported to Heidelberg Engineering worldwide, it is a known fact that flickering light with frequencies in the range
of the SPECTRALIS imaging frame rate can trigger epileptic seizures
in sensitive persons.
Typically these incidents are triggered if both eyes are exposed to the
light source, where during a SPECTRALIS examination only one eye is
exposed. However, particularly in imaging modes with clearly visible
light sources like MultiColor, FA, and BAF, explain to each patient that
the light is very bright and flickers. Discontinue the examination if there
are any signs of epileptic symptoms.

Technical Description
1.9.1
Confocal Laser Scanning
For acquiring digital confocal images, a laser beam is focused on the
retina. The laser beam is deflected periodically by means of oscillating
mirrors to sequentially scan a two-dimensional section of the retina.
The intensity of the reflected light or of the emitted fluorescent light at
each point is measured with a light sensitive detector. In a confocal
optical system, light reflected or emitted outside of the adjusted focal
plane is suppressed, resulting in high contrast images.
Furthermore – especially during indocyanine green angiographies
(ICGA) – the confocal optical system acquires a layer-by-layer threedimensional image. This system allows clinicians to image patients
with poorly or non-dilated pupils, which is especially important for diabetic patients who do not dilate well and make up a large proportion of
patients in a retina clinic.

Preface

Technical Description
Fluorescence dyes are excited in relatively narrow wavelength bands.
Using a laser is the most efficient way for excitation, since all the
energy is concentrated at one specific wavelength rather than in a
broad continuum as with ordinary flash photography light.
The SPECTRALIS requires considerably less retinal light exposure
than photographic systems, thus allowing for safer and more patientfriendly examination.
The laser sources of the device emit laser light with four different
wavelengths:
▪ A blue laser diode with wavelength 486 nm is used to excite the fluorescein or the intrinsic autofluorescence. A barrier filter at 500 nm separates excitation and fluorescence light. The same wavelength without
the barrier filter is used to create red-free images, also called blue
reflectance images. The SPECTRALIS is also capable of high quality
BluePeak autofluorescence imaging.
▪ A diode laser at 786 nm wavelength is used with a barrier filter at 830
nm to separate excitation from fluorescence in the retina using indocyanine green dye.
▪ A diode laser at 815 nm wavelength produces infrared reflectance (IR)
images.
▪ A diode laser at 518 nm wavelength (Option).
When using simultaneous imaging modes, each image line is scanned
individually by each laser. For example, during simultaneous fluorescein and indocyanine green angiography, only the 486 nm laser is
switched on for the first scan of a line, while during the second scan
only the 786 nm laser is switched on. In every acquisition mode, individual images, temporal image sequences, or a focal series of images
(layered three-dimensional images) can be acquired.

Technical Description
Heidelberg Noise Reduction
1.9.3
TruTrack Active Eye Tracking enables the capture of multiple images
in the exact same location. The automatic real time (ART) mean function combines these images, helping clinicians to discriminate between
image “noise” and true signals from real tissue structures. Noise is
effectively eliminated and the result are images of high contrast with
finer detail.
MultiColor Scanning Laser Imaging (Option)
MultiColor image
Blue reflectance image
Green reflectance image
Infrared reflectance image
MultiColor – Scanning Laser Imaging is the latest addition to the
SPECTRALIS multi-modality imaging platform. It is an optional retinal
fundus imaging modality for all SPECTRALIS models.
MultiColor images are composed of three selective, simultaneously
acquired color laser images: infrared, green and blue reflectance.
Based on the core technologies of confocal scanning laser, active live
eye tracking and noise reduction technology, MultiColor images demonstrate high image contrast and resolution. Without a flash light and
no need for pupil dilation this entirely non-invasive fundus imaging
modality significantly improves patient comfort as compared to color
fundus photography. In addition, simultaneous imaging with multiple
laser colors selectively captures and portraits diagnostic information
originating from different retinal structures within a single examination.
▪ Blue reflectance highlights epiretinal membranes, nerve fiber layer and
macular pigment.
▪ Green reflectance highlights blood, blood vessels and exudates.
▪ Infrared reflectance highlights drusen, RPE abnormalities and changes
in the choroid.
Along with the MultiColor image all three color laser images can be
viewed and analyzed individually in the MultiColor viewing software.

Heidelberg Eye Explorer (HEYEX)
Heidelberg Eye Explorer (HEYEX)
Acquisition software
Analysis software
Network licenses (Option)
Connection of practice management software (Option)
Image Capture Module
All Heidelberg Engineering devices operate on the Heidelberg Eye
Explorer (HEYEX) platform. HEYEX hosts the patient database, from
which the user manages patient files and performs examinations.
HEYEX also hosts the image acquisition and analysis applications for
the different Heidelberg Engineering devices.
The following add-on options are available for HEYEX:
▪ Network Licenses
▪ External System Interface (Option)
▪ Additional analysis software
Acquisition and Analysis Software
In addition to the operating software, including the acquisition and
analysis software provided with each device, additional optional
viewing software is also available. This viewing software enables full
access to all images and patient data on PCs which are not connected
to the device.
Network Licenses
All Heidelberg Engineering devices can be used within a network environment. This allows users to review images from networked PCs,
often referred to as viewing stations, using the same analysis software
that is used on the instrument PC.
In a network environment the common HEYEX database containing all
patient data is located on a network server. Images acquired with the
device are saved to this database. Viewing and analyzing these
images is possible at any computer that meets the viewing station
requirements. A viewing station receives access to the database
through a network license. The network license can be fixed – permanently assigned to a computer – or floating – many viewing stations
share a defined number of licenses.
Each device includes at least two floating network licenses. If viewing
access for more concurrent users is required, additional network
licenses can be purchased.
External System Interface
(Optional)
HEYEX can exchange patient data and images with other compatible
systems in the department, e.g. Electronic Medical Record systems,
Image Management Systems, PACS, etc.
The interface is deployed via the DICOM standard or via a proprietary
interface.

General HEYEX Settings
L CAUTION
Wrong classification results caused by corrective lenses.
 Ask the patient to remove glasses or contact lenses before the
examination.
 Always consider that classification results of patients with intraocular lenses may be wrong.
Classification results may be wrong for patients wearing glasses
or contact lenses or patients with intraocular lenses. Wrong classification results may lead to wrong diagnostic conclusions
which may result in wrong therapeutic approaches.
Perform the SPECTRALIS scan before other diagnostic studies that
may irritate or dry the cornea. For patients with dry eyes and contact
lens wearers, apply artificial tear fluid shortly before the examination.
Make sure that the patient is not distracted during fixation, e.g. persons
walking by.
The following explanations can help patients to understand the importance and purpose of the examination.
Explaining the Fundus Examination
The structure of the multi-layered retina in the posterior segment of the
eye cannot be examined with conventional methods. With the
SPECTRALIS fundus examination we can exactly display the retina
and provide unmatched detail and contrast in angiography and reflectance images of both, the retina and the choroid, improving the diagnosis of pathologies. The examination with the SPECTRALIS is completely safe, without touching the eye. A light beam scans the retina
and the optic nerve head.
Please put your chin on the chin rest and your forehead against the
forehead rest. For best image quality, please lean your forehead
against the forehead rest for the duration of the examination. I will
move the device close to your eye, but won’t touch it. Please look at
the blue dot. You are allowed to blink, the examination results won’t be
affected. The examination will take only a few seconds. I will let you
know when the examination has finished.

Wrong classification results caused by corrective lenses.
 Ask the patient to remove glasses or contact lenses before the
examination.
 Always consider that classification results of patients with intraocular lenses may be wrong.
Classification results may be wrong for patients wearing glasses
or contact lenses or patients with intraocular lenses. Wrong classification results may lead to wrong diagnostic conclusions
which may result in wrong therapeutic approaches.
L WARNING
Wrong classification results caused by incorrectly entered patient
data and eye data.
 Enter the patient's date of birth correctly.
 Enter the patient’s C-Curve values correctly.
Classification results may be wrong if the patient’s eye data or
date of birth is entered incorrectly. Wrong classification results
may lead to wrong diagnostic conclusions which may result in
wrong therapeutic approaches.
“C-Curve” values are relevant to the SPECTRALIS. Keratometry is
required to get a proper transverse measurement parallel to the retinal
surface in B-scans and in HRA images. Keratometry is not necessary
to obtain correct measurements perpendicular to the retinal surface, for
example RNFL thickness measurements.
If no “C-Curve” values have been entered, the standard value is 7.7.
This value is equal to the K value of Gullstrand's model eye. The typical range of a K value is 7.2 – 8.4 mm. If a K value is wrong by
0.1 mm, the resulting error in a distance measurement parallel to the
retinal surface is 0.8 %.

Only use objective lenses provided by the manufacturer.
The incorrect use of lenses on the SPECTRALIS camera, or the
use of unauthorized lenses may result in the patient's retina being
exposed to hazardous laser light.
Artifacts due to reflections from internal optics can be visible in
reflectance images.
 Do not mistake this artifact for a pathology.
Residual reflections from optical surfaces may appear as bright
spot artifacts in reflectance images. Central artifacts are more
likely for patients with lower fundus signal, e.g. patients with cataract or small, undilated pupils as well as for patients with high
myopia.
L CAUTION
Wrong classification results caused by corrective lenses.
 Ask the patient to remove glasses or contact lenses before the
examination.
 Always consider that classification results of patients with intraocular lenses may be wrong.
Classification results may be wrong for patients wearing glasses
or contact lenses or patients with intraocular lenses. Wrong classification results may lead to wrong diagnostic conclusions
which may result in wrong therapeutic approaches.

Setting Default Acquisition Parameters
In order to accelerate the volume scan acquisition, the actual number
of averaged images for ART Mean may differ from the pre-selected
number of ART Mean images. The maximum difference increases with
the absolute number of ART Mean images. This will affect image
quality only marginally.
For best image quality clean the lens before an examination.

High Magnification Images
Fig. 33: Images acquired with a scan angle of 30°, 20°, and 15°
High magnification images are especially useful when performing an
ICGA to locate a feeder vessel. For further information on performing
an angiography, please refer to ( Chapter 7.6 “Performing an
Angiography”, p. 88).
Selecting a higher magnification on the device works like the digital
zoom on a digital camera. The smaller the selected angle, the lower
the number of pixels used for acquiring the area of interest. The
advantage of a 15° scan angle is the higher magnification on the
screen, smaller file size and higher frame rates, which are especially
suited for movies of the early phase.
For best image details, select “High Resolution” as the scan resolution
mode when increasing the magnification.

Acquiring a BluePeak Blue Laser Autofluorescence Image
L WARNING
A patient that is not optimally prepared for the acquisition of
BluePeak blue laser autofluorescence images may cause bad
image quality.
 For best image quality, Heidelberg Engineering recommends to
acquire BluePeak blue laser autofluorescence images with dilated
pupils.
 In order to improve the image quality for patients with cataract,
dilating the pupils might improve the image quality.
Bad image quality may lead to wrong diagnostic conclusions
which may result in wrong therapeutic approaches.
For BluePeak blue laser autofluorescence imaging, no dye injection is
necessary.
Always acquire BluePeak blue laser autofluorescence images before
injecting dye and performing angiographies.

Acquiring MultiColor Images (Option)
The following chapter provides an overview of the image acquisition
with the SPECTRALIS MultiColor.
L CAUTION
MultiColor images are not true color images and can appear different from color fundus photos.
MultiColor images may not be used as a surrogate of color
fundus photos for medical diagnosis. A MultiColor image is composed from reflectance images acquired with three discrete illumination wavelengths (infrared, 815 nm; green, 518 nm; blue, 486
nm). In contrast, a true color image is acquired using a continuous spectrum of light (white light) for illumination. In addition,
MultiColor images are acquired with a smaller depth of focus than
fundus camera images. Therefore, a MultiColor image does not
represent the true color of the examined structure, and significant
color differences can exist between MultiColor images and
fundus photos. The color differences depend on the examined
structure, on the pathology of the examined structure, and on the
focus setting.
“HR” cannot be selected as the scan resolution when acquiring MultiColor images.
Stereo fundus images cannot be selected as the acquisition modality
when acquiring MultiColor images.

L CAUTION
Artifacts due to reflections from internal optics can be visible in
MultiColor images.
 Do not mistake the artifact for a pathology.
Residual reflections from optical surfaces may appear as bright
spot artifacts in reflectance images. Central artifacts are more
likely for patients with lower fundus signal, e.g. patients with cataract or small, undilated pupils as well as for patients with high
myopia.

Setting an ETDRS Grid
The ETDRS (Early Treatment Diabetic Retinopathy Study) grid has
four concentric circles with radii of 360, 600, 1,800 and 3,600 microns
with two bisecting lines. ETDRS was a multicenter, randomized clinical
trial designed to evaluate argon laser photocoagulation and acetylsalicylic acid treatment in the management of patients with nonproliferative
or early proliferative diabetic retinopathy. A total of 3,711 patients were
recruited to be followed for a minimum of four years to provide longterm information on the risks and benefits of the treatments under
study. For further information, please refer to
http://clinicaltrials.gov/ct2/show/NCT00000151.

ART Mean
If Automatic Real Time (ART) Mean is switched on, the section “ART
Mean” is displayed. With ART, mean images are created automatically, which increases image quality due to noise reduction. For performance reasons, this process has a tolerance, so the actual number
of frames used to create the mean image may vary up to ±10%.
If you want to check the number of images averaged, select
“Image \ Image Information” in the analysis window's menu bar. In the
“OCT image” section, the number of images averaged is given in the
“ART Mode” entry.
AQM
AutoRescanTM
BAF
Acquisition module
TruTrackTM active eye tracking creates a detailed retinal map each
time a patient is imaged. The AutoRescanTM feature uses this map to
automatically place follow-up scans in precisely the same location as
the baseline scan. Once a scan is marked for follow-up, the
AutoRescan feature will find the desired location, eliminating subjective
operator placement and increasing clinician ability to observe true
change over time rather than change resulting from alignment error.
AutoRescan precision has been documented in studies showing that
the SPECTRALIS system offers 1 μm measurement reproducibility
(Wolf-Schnurrbusch UE et al. Macular Thickness Measurements in
Healthy Eyes Using Six Different Optical Coherence Tomography
Instruments. Invest Ophthalmol Vis Sci. 2009;50:3432-3437).

HR
High resolution mode; if you select HR as the scan resolution mode,
images are acquired with a higher spatial scan resolution but with a
low scan rate. HR acquires more data points over a longer time period
and requires more time and space for data storage.
HS
High speed mode; if you select HS as the scan resolution mode,
images are acquired at a faster rate but will be of a lower resolution.
HS is optimized for fast image acquisition with a high frame rate and a
minimum need for data storage.

TruTrackTM Active Eye Tracking
TSA
VWM
The SPECTRALIS platform simultaneously images the eye with two
beams of light. One beam captures an image of the retina and maps
over 1,000 points to track eye movement. Using the mapped image as
a reference, the second beam is directed to the desired location
despite blinks or saccadic eye movements. TruTrackTM dual-beam
technology mitigates eye motion artifact and ensures point-to-point correlations between OCT and fundus images without post-processing of
the data
