Spectralis HRA
- Highest Image Contrast and Detail
- Lowest Light Exposure
- Fluorescein Angiography (FA)
- ICG Angiography (ICGA)
- Simultaneous FA and ICGA
- Infra-red and Blue Reflectance
- Autofluorescence
- Stereo and Widefield Imaging
HRA 2 enables you to perform standard high-resolution and
high-contrast fluorescein and ICG angiography as well as
autofluorescence (488 nm) imaging with high quality.
Using the normal FA settings, but without the injection of
fluorescein, autofluorescence imaging can increase physician
confidence by confirming the diagnosis in such conditions as
macular holes, pseudo-vittelliform lesions, RPE Atrophy, Central
Serous Chorioretinopathy and Best's disease.
A unique feature of the HRA 2 is the ability to acquire dynamic,
highspeed movies (up to 16 frames per second) in both Fluorescein
or ICG Angiographies. This is especially important in the initial
phase of FAs, when documentation of the early filling stages is
necessary. In ICGA, this feature enables better detection of CNV
characteristics such as feeder vessels and RCA/RAP's. It's great
for teaching.
Never before have you been able to see dynamic angiography
sequences and the movie feature allows a retrospective review of
your angiographies.
Every time you review a movie it's like being there at the time of
the procedure. While going over the acquired image series you can
extract single images from the sequence which can be viewed and
printed if necessary.
Spectralis OCT
The ground breaking development in Spectral Domain OCT provides
clinicians with never before seen details of the structure of the
retina. The new device scans the retina 100 times faster than
older existing technology known as time domain OCT.
Spectralis™ OCT is a spectral domain system, sometimes called
fourier domain, which scans the retina at 40,000 scans per second,
creating highly detailed images of the structure of the
retina.
"This new technology represents a dramatic leap in our ability to
image complex macular disease," said Scott Cousins, MD, director,
Duke Centre for Macular Diseases, at Duke University. "The
combination of these two cutting edge technologies will amplify our
understanding of retinal structure and provide us with new insights
into the biological processes of the retina."
Spectralis HRA+OCT
The new Spectralis™ HRA+OCT detects previously
unrecognized structures, combining high resolution cross-sectional
images of the retina with any of five imaging modalities:
autofluorescence, infrared, red free, fluorescein angiography,
or ICG angiography.
Because the OCT and HRA images are captured simultaneously, the
clinician can be assured of the exact location of the area of
interest and can correlate the outer visible retina structure with
the internal structure.
The new product is built on the company's successful Heidelberg
Retina Angiograph (HRA) platform, the first commercial angiography
system to use lasers in combination with marker dyes such as sodium
fluorescein and indocyanine green (ICG). Using the HRA instead of
white light photography has allowed clinicians to capture detailed
images of the blood vessel structure within the retina, a key
diagnostic indicator for such common eye disease as age-related
macular degeneration and diabetic maculopathy. Another advantage of
using lasers is the fast frame rate which enables movies of the
blood flow, adding a new diagnostic dimension over traditional
photography.
