GA Grader is an innovative software tool to monitor progression of Geographic Atrophy (GA) secondary to age-related macular degeneration (AMD).


  • Automatic segmentation of areas of atrophy of the retinal pigment epithelium in the context of GA secondary to AMD, based on analysis of imported volume optical coherence tomography (OCT) imaging data that has been acquired with the Spectralis imaging platform (Heidelberg Engineering GmbH, Germany)
  • Visual segmentation of atrophic areas
  • Determination of absolute values in mm2 of total lesion size, the largest single lesion and additional individual lesions (if present) and number of spots.
  • Progression analysis, including visualization of the spread of atrophic areas as well as calculation of area progression over time
  • Comparison analysis between OD and OS, provided both eyes have GA.
  • Determination of the size of the residual island of foveal sparing atrophy, the minimum distance of any atrophy to the fovea and its changes over time



GA Grader is natively integrated with Heidelberg Heyex 2. Patient data will be analyzed by GA Grader and a analysis report sent back by a simple drag and drop operation within the Heidelberg Heyex 2 user interface



  • The GA Grader Tool is currently available for research purposes only.
  • GA Grader analysis performance is constantly monitored and improved by GRADE Reading Center experts.
