The Humphrey FDT Perimeter uses Frequency Doubling Technology to provide a clinically verified, fast and affordable means of detecting early visual field loss. The FDT is the ideal visual field screening device because it conducts supra-threshold testing in only 35 seconds per eye.
Remarkably affordable, the FDT brings visual field testing to any size practice, even the smallest. In addition to fast supra-threshold testing, it also conducts threshold testing complete with statistical analysis in about 4 minutes.
Visual field testing is a basic element in the standard of care for glaucoma management.
