Heidelberg Spectralis® HRA
- 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.
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.
BluePeak 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.
