MORE SUPPORT FOR FDT

Journal of Glaucoma - Abstract: Volume 15(2) April 2006 p 77-83 Frequency Doubling Technology Perimetry With the Humphrey Matrix 30-2 Test. Here's another study that demonstrates that:

"FDT perimetry appeared more sensitive than standard automated perimetry in detecting early glaucomatous fisual field loss. The FDT-N-30 test showed a slightly higher ability to detect early glaucomatous damage in patients at risk for the development of glaucoma, whereas the 30-2 test provided a more detailed characterization of the glaucomatous VF loss pattern, although it required 30% more time."
