perimetry are not interchangeable. The Goldmann perimeter can also be used for manual static threshold perimetry, and other machines are also available for manual kinetic perimetry. Similarly the Humphrey Field Analyzer is capable of performing kinetic perimetry as well as static threshold perimetry. For the purpose of serving as an Visual function assessment is integral to the evaluation and management of glaucoma.

The Humphrey uses fixed points of light which are shown at different intensity levels. Dr. Shafranov notes that the Humphrey Matrix compares better to SAP than the original FDT instrument did. "The Matrix allows resolution identical to what standard automated perimetry gives us," he says. "That was the main advantage standard automated perimetry had over the original FDT (from Welch Allyn); it tested more spots in the visual field.

Frequency Doubling Perimetry Technology or Frequency Doubling Technology (FDT) Perimetry is a procedure used to detect visual field loss caused by Glaucoma and other Ophthalmological diseases. An enhanced version of FDT Perimetry has been released called the Humphrey visual field test or the Humphrey Matrix.
