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. 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 glaucomatous visual field defects. Automated perimetry sensitivity was 90.38%, while automated perimetry specificity was 91%.

Static perimetry uses flashing stationary lights. This can be automated (eg, evenly spaced points on a grid) or manual (eg, as a small part of Goldmann test: detailed later). The Humphrey field analyser is by far the most commonly used for automated static perimetry, although there are also other machines such as Octopus and Henson. Other names for this test may include perimetry, Tangent screen exam, Automated perimetry exam, Goldmann visual field exam, or brand names such as Humphrey Field Analyzer, Octopus Perimeter, Optopol PTS perimeter, Oculus Easyfield perimeter, Olleyes VisuALL, etc. 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.

Automated perimetry sensitivity was 90.38%, while automated perimetry specificity was 91%. Main outcome measures: The patients were tested by tangent screen, Goldmann, and Humphrey perimetry (central 30-2 threshold program). The three visual fields were compared and correlated with MR images. Results: All three perimetric techniques detected the presence of postchiasmal lesions. Goldmann perimetry is a common example of kinetic perimetry.

Fifty-two patients and a technician took part in a survey to determine their preference for either test.

Humphrey When you are doing Goldmann, you need to “do the math” that will tell you what correction you need for the test. The Humphrey machine will do the calibration for you – but……… Does the Humphrey know if a patient has had cataract surgery and has an IOL or not ?! Batman Comics: The Riddler No !!!!!

In kinetic perimetry, target size and luminance are ﬁxed and the target is Se hela listan på eyewiki.aao.org Later, we describe in detail the interpretation of Humphrey perimetry. Kinetic perimetry uses a moving illuminated target and is done either manually (eg, Goldmann) or on an automated machine (eg, Octopus). Goldmann machines are no longer manufactured, being slowly replaced by Octopus machines. Goldmann kinetic and Humphrey static perimetry results are not amenable to quantitative comparisons because of the different formats of data produced by each device.
