test whose test point locations correspond to the 30-2 full threshold test. The 80-point test has the advantage of testing additional points in the nasal step area around the horizontal meridian. It also has additional test points compared with the 76-point Comparison between Fastpac and conventional Humphrey perimetry 97

DISCUSSIONFDT perimetry has shown several advantages over SAP, including the following 19 : low cost; transportability; tolerance to blur, pupil size, and refractive errors 20 ; shorter test time; and lower test-retest variability. 21 Furthermore, several studies have suggested that FDT may be able to detect VF loss before SAP. 6 Although the first FDT version uses considerably larger targets

To avoid this, cancel Perimetry is the measurement of “Hill of Vision” in terms of establishing the patient’s differential light sensitivity. There are mainly two types of perimetry test: Kinetic (ie. Bjerrum’s screen, Goldmann, Lister perimetry) Static /automated (ie. Humphrey, octopus) We will be discussing about how to evaluate the Humphrey visual field The ages ranged from 15 to 35 years, with a mean age of 25.9 years.

This test means that the central 24 degrees of the visual field were analysed. The reason to why this test is the most common is due to it being easier to asses whether visual field defects respect the horizontal or vertical For the Humphrey perimeter, a test stimulus of 4 mm 2 (corresponding to a Goldmann size III stimulus) is most commonly used, though larger stimulus sizes may be employed for individuals with poor visual acuity. The Humphrey perimeter tests light intensities over 5 orders of magnitudes, from 10,000 apostilbs (asb) to 0.1 asb. 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).

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. Reduce visual field testing time with SITA™ Faster. Central testing to view into the macula with SITA Faster 24-2C

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.

It also has additional test points compared with the 76-point Comparison between Fastpac and conventional Humphrey perimetry 97 2008-01-24 · This is a short test option that takes about 15 seconds that can be employed at the beginning of the primary test if you're using the Humphrey perimeter (Carl Zeiss Meditec).

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)! For acceptable tests performed on a Humphrey Field Analyzer, an MD equal to or greater than -5 dB (for example, -4.39, -2.58, or 0) indicates that the visual field is normal. An MD less than -5 dB (for example, -5.5, -8.85, or -11.18) indicates the individual has visual field loss. 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. perimetry are not interchangeable.

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.
