SPECTRALIS software adds macular reference database and deviation maps functionality

Example of the new Thickness Map and Thickness Deviation Map with temporal inferior arcuate RNFL defect.
Hemel Hempstead, United Kingdom – SPECTRALIS Glaucoma Module Premium Edition (GMPE) customers having installed the SPECTRALIS release 6.12.1 can now benefit from the discriminative power of the macular reference database with the addition of thickness deviation maps for retina, retinal nerve fibre, ganglion cell and inner plexiform layers. This feature is free of charge to all SPECTRALIS owners with GMPE Module. The Deviation Maps update offers:

  • Thickness deviation maps, which highlight whether the thickness measurements of each retinal layer are within or outside of normal limits in comparison to a reference database, making the regions and extent of structural thickening or thinning clearly discernible.
  • New thickness maps with a perceptually uniform colour scale that make changes in retinal thickness more easily perceived by the human eye in comparison to the traditional hue colour scale.
  • Classification chart with values derived from a Garway-Heath 6 sector grid, accurately anatomically aligned on the macular according to the individual anatomy of each eye using the Anatomic Positioning System (APS).

“The comparison of thickness measurements with the reference database enhances the diagnostic value of thickness maps and improves the visualisation of structural defects consistent with glaucoma”, explains Tim Cole, Clinical Market Development Manager, Heidelberg Engineering UK. “Heidelberg Engineering is well renowned for having revolutionised glaucoma diagnostics after bursting onto the scene with the Heidelberg Retina Tomograph (HRT) in 1999. The launch of Deviation Maps, and the Glaucoma Hood Report earlier in 2019, shows a continued commitment by the company to developing innovative and clinically validated diagnostic solutions for glaucoma.”
