SPECTRALIS® HRA

A Deeper, Clearer Picture of the Retina

  • Simultaneous FA and ICGA
  • Dynamic motion imaging
  • Deep tissue infrared imaging
  • Autofluorescence of the RPE
  • Ultra-widefield imaging
  • Network and remote viewing

Digital cameras are giving way to the confocal scanning laser, adding motion, depth, and clarity to fundus imaging. Rather than struggling to manipulate random white light from a flash, lasers enable pinpoint location and ideal wavelength selection.

Spectralis HRA vs. Digital Camera

Dual-beam Technology Enables Simultaneous FA and ICGA

The SPECTRALIS® HRA is optimized to match the peak excitation of fluorescein and ICG, and can image both dyes simultaneously, providing a picture of both retinal and choroidal circulation at the same time. Not only are the images clearer and more detailed than traditional fundus cameras, but rapid scan speeds enable dynamic imaging, capturing the subtleties of partial blockages of blood flow.

Infrared Lasers Get Images When Flash Cameras Cannot

The infrared imaging capability of the SPECTRALIS® expands the range of patients that can be imaged when poor media, small pupils or lack of dilation hamper traditional fundus cameras. These types of cases can be small in number, but big in need. Often the most difficult patients have the greatest diagnostic need. The invisible infrared light helps keep the pupil from closing and cuts through cataracts and hazy media better than white light.

Infrared light penetrates deeper into tissue, often revealing structural changes which may not be visible under contact lens examination or on white light photos. The outline of CSCR or PEDs may be more distinct due to deeper layer reflections.

Spectralis HRA Geographic Atrophy

Autofluorescence Provides Quantitative Assessment of RPE Health

Autofluorescence uses the natural properties of the cell to obtain images without any dye. Autofluorescence helps to identify areas of RPE not functioning well enough to process lipofuscin accumulation. Lack of lipofuscin (or hypofluorescence) may be an indicator of missing or damaged RPE. Too much lipofuscin (hyperfluorescence) may indicate the first signs of a malfunctioning RPE.

Characteristic patterns of autofluorescence are now being used to track areas of geographic atrophy in dry AMD and are even more established in revealing Best’s and Stargardt’s diseases.

Spectralis HRA Macular Hole

Ultra-Widefield Imaging with Zoom-In Detail

The SPECTRALIS® HRA has multiple ways of obtaining high resolution images covering wider areas of the retina. Using either the 35 or 55 degree lenses, the SPECTRALIS® can pan the retina, painting a real-time, ultra-widefield image showing zoomed-in detail unmatched by other technologies.

The Staurenghi 150° contact lens adds yet another dramatic view of the posterior pole only achievable with a confocal scanning laser.
