Matrix Visual Field

Frequency Doubling Technology Perimetry (FDT), also called Matrix Visual Fields, has been shown to offer a high sensitivity and specificity in the early detection of glaucomatous changes and several other ocular or neurological disorders.

FDT testing also offers a few other advantages:

• Testing results are not greatly affected by cataracts or high refractive erros, thus allowing a high degree of reliabilty.
• Patient reliablity can increase because the test is more rapidly administered than other perimetry testing.
