test ranges for the periphery were 90 for Humphrey, OCULUS, and OCTOPUS GKP, and 80 for Kowa. Conclusion To assess kinetic fields with various defect patterns, OCTOPUS GKP seems to be the most useful method.

Canada. SUMMARY Humphrey automated threshold perimetry (Program 30-2) was performed on 42 eyes visual field tests using preprogrammed and/or pro-.
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. 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 On the Humphrey Field Analyzer (shown here), the best threshold test is the SITA-Standard.
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.

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).
The blind spot was mapped out using a I2e or I4e test object to ensure patient reliability. Relative defects in the visual field were then mapped out using three
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 test ranges for the periphery were 90 for Humphrey, OCULUS, and OCTOPUS GKP, and 80 for Kowa. Conclusion To assess kinetic fields with various defect patterns, OCTOPUS GKP seems to be the most useful method.

The first two editions introduced Humphrey perimetry itself (in 1986) and the internationally-based normative data application we called Statpac (in 1987). 2009-05-01 on the FDT perimetry and the Humphrey total deviation plot showed a significant correlation for both the location and the depth of the defect.

c. 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 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). It can provide valuable information, for example, when a patient with advanced glaucoma that is close to fixation complains that her vision is worse, yet Snellen acuity and the 24-2 field appear unchanged. Reasons include the short duration of the test (5 min), and the appearance like a pleasant game to 80% of the subjects tested.
