Journal of Glaucoma - Abstract: Volume 16(4) June/July 2007 p 372-383 Can Frequency-doubling Technology and Short-wavelength Automated Perimetries Detect Visual Field Defects Before Standard Automated Perimetry in Patients With Preperimetric Glauc

According to this study:

FDT and SWAP detect functional losses in cases of suspected glaucoma before glaucomatous losses detected by standard perimetry.
