Here, we’ll only talk about the Humphrey visual field perimeter, which is used for 99% of visual field tests. It’s an automated, static perimeter (unlike Goldmann kinetic perimetry which requires a human operator, and uses a moving target). The Humphrey uses fixed points of light which are shown at different intensity levels.

Rapid screening procedures permit testing in community-based populations, children, individuals who are not able to perform conventional visual field testing, and individuals with limited access to Slideshow search results for perimetry Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising.

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. 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.

Unfortunately, little information is yet available on the reproducibility of SKP (using Octopus 900 and HFA3) in comparison to Goldmann perimetry, with only few studies yet published. In Aim. To compare semikinetic perimetry (SKP) on Octopus 900 perimetry to a peripheral static programme with Humphrey automated perimetry. Methods.
