AIM—To determine the number of missed points on frequency doubling technology (FDT) perimetry that optimise the sensitivity and specificity of the test and to determine the topographical accuracy of the test in a clinical setting. METHODS—In a prospective study, the perimetric data from 99 patients who underwent both FDT perimetry in the screening mode and Humphrey 24-2 (H24-2) were used

Static automated perimetry (such as Octopus or the Humphrey Field Analyzer): Pinpoint flashes of light of varying size and brightness are projected within a large white bowl. Goldmann visual field test Goldmann visual field perimetry is not as widely available as Humphrey visual field because it requires skilled perimetrists who manually map the visual field without the aid of a computer algorithm. Light is projected into a white bowl with a standardized background light intensity. The most common threshold test carried out in an automated perimetry test (i.e Humprey visual field) is Central C24-2. This test means that the central 24 degrees of the visual field were analysed. This test is most often used to detect central visual field defects.

2016;5(4):4, doi:10.1167/ tvst.5.4.4 Purpose: We determined the receiver operating characteristic (ROC) curves for Peristat online perimetry at detecting varying degrees of glaucoma and the correlation between Peristat online perimetry and Humphrey visual field. The gold standard in visual field testing, Humphrey Field Analyzer 3, now combines everything you value in a Humphrey with expanded testing options and Methods: A prospective, comparative study of Peristat online perimetry (an achromatic static computer threshold testing program) and Humphrey visual field Results: Overall, patients performed reliably in 52% of visual field tests. The most common cause of poor reliability was fixation loss, with 43% of patient tests Humphrey Visual Field Test. Visual field testing is one of many methods used to diagnose and monitor glaucoma progression.

For example, the central vision of the eye The Humphrey Visual Field Analyser is the gold standard of visual field screening used by eye hospitals.

Humphrey automated threshold perimetry (Program 30-2) was performed on 42 eyes of 25 patients with glaucoma to determine both the sensitivity and specificity of automated perimetry in detecting

It is best to catch these readings while the test is in progress and restart the test. A typical "normal" dB reading is around 30. The numeric dB graph should be studied next. The dBs tested by the Humphrey analyzer range between 0 and 50 dB (0 is the brightest and 50 is the dimmest).

How to use the frequency doubling perimeter for glaucoma screenings. How to use the frequency doubling perimeter for glaucoma 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. 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.

HFA3 delivers the interactive analysis you need, when and where you need it. Reduce visual field testing time with SITA™ Faster. Central testing to view into the macula with SITA Faster 24-2C. The Humphrey perimeter provides the deviation from normal in a graphic printout through its STATPAC program.52 For each point tested, STATPAC provides the statistical probability that the patient's threshold would be found in the normal population (Fig. 10-20). 2017-04-30 · The most common threshold test carried out in an automated perimetry test (i.e Humprey visual field) is Central C24-2. This test means that the central 24 degrees of the visual field were analysed.

SITA (Swedish Interactive Threshold Algorithm)  SWAP (Short Wavelength Automated Perimetry) and 30-2 less useful  10-2 For advanced Glaucoma  Not directly comparable with Octopus or Medmont (different algorithms)!
