In clinical practice, these fields are often obtained with office-based static automated perimetry such as the Humphrey visual field (HVF; Carl Zeiss Meditec). 2019-10-17 Start the test 39 Main Menu 40 Patterns of threshold testing Central 30-2 ’30’ stands for central 30˚ ‘2’ stands for 2nd type (test points straddle the midline vs. 30-1 where points are on the midline) 76 points total are tested with each point separated by 6˚ of visual space 41 Humphrey 30-2 test pattern 42 Humphrey 30-1 test pattern 43 2008-01-24 2015-10-01 A visual field test is an eye examination that can detect dysfunction in central and peripheral vision which may be caused by various medical conditions such as glaucoma, stroke, pituitary disease, brain tumours or other neurological deficits. Visual field testing can be performed clinically by keeping the subject's gaze fixed while presenting objects at various places within their visual field. Simple manual … Writing this 5th edition of the Humphrey primer has reminded us of just how much visual field testing has evolved since the days when we wrote each of the previous editions. 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.

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.

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.

Perimetry programs which meet these criteria include the Humphrey 30-1, 30-2, 24-1, 24-2, SITA Fast, and SITA Standard Visual Field Tests, and the Octopus 30-1 and 30-2 Visual Field Tests. Reporting of visual fields should always include the actual thresholds determined for each field point and the number of false positives, false negatives and fixation losses.

Reporting of visual fields should always include the actual thresholds determined for each field point and the number of false positives, false negatives and fixation losses. Validato da oltre 25 anni di ricerca, progettazione ed esperienza clinica, Humphrey Field Analyzer (HFA) rappresenta lo standard riconosciuto per la diagnosi e il trattamento del glaucoma. Con oltre 65.000 unità installate in tutto il mondo, HFA è l’analizzatore di campo visivo automatizzato per eccellenza.

GDx VCC, Stratus OCT Perimetry (or visual field testing) is a vision test used to evaluate a patient's peripheral vision. It involves a patient fixating on a central target and pressing a button when they see a spot of light in their peripheral vision. It is an important way of deciding whether Glaucoma is progressing or not.
