Fovea-to-Disc(FoDi™) Alignment Technology

The SPECTRALIS® platform features a unique fovea-to-disc alignment technology that automatically tracks and anatomically aligns circle scans, improving accuracy and reproducibility of RNFL measurements.

Minimize Patient Position Changes

FoDi alignment technology helps overcome measurement errors due to head tilt and eye rotation.

Without Alignment

Head tilt and eye rotation affect the anatomical alignment of the scan

Attain Higher Confidence

SPECTRALIS FoDi alignment technology reduces noise caused by misalignment of scans and improves the accuracy to detect individual change over time. Scans in a series are aligned along the fovea-to-disc axis ensuring point-to-point thickness comparisons between patient visits. Follow-up scan variability and rotational artifact are reduced with FoDi, increasing overall confidence in the test.
