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.

on the FDT perimetry and the Humphrey total deviation plot showed a signiﬁcant correlation for both the location and the depth of the defect. In comparing the Humphrey hemiﬁeld test with the FDT perimetry results, if at least one missed point on the frequency doubling …

The nature of these tests required specific test algorithms with clearly defined test sequences and termination criteria. The method adopted in the Humphrey Visual Field Analyzer (HFA) was to use the standard full-threshold strategy at four visual field locations (12.7° from fixation along the 45, 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).

Matrix allows higher resolution of visual field defects. In fact, Matrix appears to be more sensitive than automated perimetry and the SWAP visual field test that's administered on the Humphrey Field Visual Analyzer II. Also, it tests slightly different parts and functions of the ganglion cells than the original FDT instrument. Humphrey Visual Field  24-2 White on White is the standard  Can be full threshold, SITA standard or SITA Fast. 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.

The method adopted in the Humphrey Visual Field Analyzer (HFA) was to use the standard full-threshold strategy at four visual field locations (12.7° from fixation along the 45, 2000-01-01 The visual field is a three-dimensional area of asubject’s surroundings that can be seen at any onetime around an object of fixation.

Transl Vis Sci Technol. 2016;5(4):4. 6. on the FDT perimetry and the Humphrey total deviation plot showed a signiﬁcant correlation for both the location and the depth of the defect. In comparing the Humphrey hemiﬁeld test with the FDT perimetry results, if at least one missed point on the frequency doubling test was considered as abnormal then the overall Humphrey tests are widely used in glaucoma clinics, the most common set up being to test the central 24° (‘24-2’ setting).

The reduction in test time is a boon for patient, doctor, and office. Glaucoma guidelines recommend patient visual field testing 3x per year in the first 2 years of

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 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.
