Topographic Change Analysis (TCA) is a statistically-based algorithm that accurately detects structural change over time by comparing variability between examinations and providing a statistical indicator of change.
HRT’s exclusive TCA technology automatically aligns subsequent images with the baseline examination, providing a point-by-point analysis of the optic disc and peripapillary RNFL.
