SPECTRALIS® HRA imaging platform is specifically designed for dye-based angiography such as Fluorescein Angiography (FA) and is equipped with several scanning laser fundus imaging techniques. As an expandable platform, it can always be upgraded with additional scanning laser fundus imaging methods such as ICGA imaging, Ultra-Widefield Angiography Module, or MultiColor Module. SPECTRALIS HRA is delivered with a panoramic camera head and an external touch panel control, which is especially useful for facilitating dye-based angiography with FA or ICGA.
MultiColor Module
Much More Than a Color Fundus Photo! The unique multicolor fundus imaging obtained simultaneously with three different laser wavelengths from various ocular tissue layers provides a composite color image that reveals topographic changes not visible with conventional color fundus photography. The different penetration depths of each
wavelength deliver structural information from each tissue layer, aiding in the identification of pathology.
You can extract diagnostic information from either monochromatic images or the multicolor composite image and integrate them into a multimodal imaging workflow to maximize diagnostic potential. When combined with OCT images, the MultiColor Module supports qualitative analysis and helps identify the specific retinal layers affected by pathology. MultiColor provides valuable additional data to Fluorescein Angiography, and when combined with OCT or OCTA, it can help determine whether contrast-enhanced fundus angiography is necessary. MultiColor can be used alongside BluePeak fundus autofluorescence imaging and is an excellent tool for measuring the extent of geographic atrophy. It allows for the quick and easy acquisition of four fundus images and simultaneous OCT in a single capture, optimizing your workflow.
The confocal microscopy technology of SPECTRALIS® further enhances imaging resolution, delivering impressive results especially useful in patients with media opacities or nystagmus. Additionally, confocal optics enable the acquisition of high-resolution images without the need for pupil dilation.
BulePeak Module
The BluePeak autofluorescence module is a non-invasive fundus imaging modality that reveals retinal metabolic stress by using lipofuscin as an indicator. BluePeak images provide diagnostic insights into retinal conditions such as AMD and inherited diseases and can uncover RPE and photoreceptor cell dysfunctions. By combining the segmentation of retinal layers in OCT images with the metabolic mapping of BluePeak autofluorescence, morphological changes associated with functional alterations become more clearly visible.
With RegionFinder software, the size of pathological areas identified in BluePeak images can be quantified and tracked over time.
Scanning Laser Angiography
High-Resolution Photos and Videos: SPECTRALIS® scanning laser angiography can be performed using either fluorescein or ICG dye. Both modes produce detailed, high-resolution images and video sequences that show vascular filling, flow, and leakage. For workflow efficiency and diagnostic precision, FA and ICGA can be captured simultaneously and in combination with OCT imaging. The optional Ultra-Widefield Angiography Module provides scanning laser angiography images from the macula to the periphery, enabling more comprehensive retinal examinations.
Widefield Imaging Module
Wide-Angle (55-Degree) Fundus Imaging and OCT: The SPECTRALIS® Widefield Imaging Module provides a 55-degree field of view for all fundus imaging modalities, including MultiColor, BluePeak, infrared imaging, angiography, and OCT. By capturing the macula, optic nerve head, and areas beyond the vascular arcades in a single image, the Widefield Imaging Module enables more comprehensive diagnostics. The high-resolution, high-contrast images obtained with this module offer diagnostic capabilities that go beyond traditional fundus photography.
Ultra-Widefield Imaging Module
Ultra-Widefield Imaging from Macula to Periphery: The SPECTRALIS® Ultra-Widefield Imaging Module captures an exceptionally wide field of view in a single shot. It provides uniform illumination and high contrast in fundus images, making it easy to visualize even the peripheral regions. The module is compatible with SPECTRALIS scanning laser angiography, including both fluorescein and ICG angiography, which can be acquired either separately or simultaneously.
High Magnification Module
High-Resolution Imaging of Retinal Microstructures! The SPECTRALIS® HMM consists of an innovative magnifying lens and specialized software. By reducing intraocular light scatter, it elegantly enhances the ability of confocal scanning laser ophthalmoscopy (cSLO) to visualize ocular microstructures—even in eyes with cataracts. The contrast and clarity of the images obtained through confocal scanning reveal critical diagnostic details that are often not visible with standard ophthalmoscopy or fundus photography.
Once the area of interest is identified using a lens with a wider field of view, the user can capture images at approximately an 8° angle, enabling highly magnified, detailed examination. This capability may offer a unique perspective on the progression of specific retinal diseases.
