Perimetry is the systematic measurement of visual field function (the total area where objects can be seen in the peripheral vision while the eye is focused on a central point). The two most commonly used types of perimetry are Goldmann kinetic perimetry and threshold static automated perimetry.

This can be automated (eg, evenly spaced points on a grid) or manual (eg, as a small part of Goldmann test: detailed later). The Humphrey field analyser is by far the most commonly used for automated static perimetry, although there are also other machines such as Octopus and Henson. On the Humphrey Field Analyzer, the visual field index (VFI)—a value similar to the MD—was added to the printout several years ago. The VFI is a staging index for the total amount of field loss. It is reported to be less sensitive to cataracts.

Program 30-2 was used on the automated perimeter; Goldmann perimetry was performed by standard methods.4 Both eyes were testedonbothmachines. Anumberof questions were then asked of … Static perimetry, of which there are several versions, uses a computer algorithm to present targets at fixed locations to delineate scotomas in a more expedited fashion. A full discussion of the differences between static and kinetic perimetry is beyond the scope of this column, however, those interested are encouraged to explore the suggested reading at the end of this article. As the gold standard of perimetry, Humphrey ® Field Analyzer 3 (HFA3) is your trusted diagnostic partner. HFA3 delivers the interactive analysis you need, when and where you need it.
