"That was the main advantage standard automated perimetry had over the original FDT (from Welch Allyn); it tested more spots in the visual field. 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.

SERVICES Humphrey Automated PerimetryWhat is Automated Perimetry? Automated Static perimetry is the most important clinical tool for measuring visual function outside the fovea.Threshold testing involves precise quantification of visual sensitivity.while suprathreshold testing is used mainly to establish whether visual function is within the normal range. Second generation Humphrey Matrix FDT perimetry The second generation Humphrey Matrix FDT Perimeter introduced several new features, including the ability to monitor eye fixation. Threshold testing on the Humphrey Matrix uses smaller targets that are presented along a grid.
Superior fields at the 12:00 meridian were 46° ± 6° taped, and 28° ± 12° untaped for Goldmann perimetry (P<.001, n = 24), and 38° ± 8° taped, and 24° ± 12° untaped for Humphrey perimetry (P<.001, n = 24) . As a result, the reports generated by Humphrey perimetry and those generated by Henson perimeters, particularly in the options for deviation probability maps, are indeed comparable. “If you’ve seen patients, and you’re monitoring them over a long period of time, an important aspect of monitoring is to use the same test,” Prof. Henson said.

Identify the historical methodologies of Perimetry Demonstrate an ability to identify the structures of the human eye. Define Amsler Grid Define Confrontational Test Define Tangent perimetry. Method: Full-threshold data (Humphrey Visual Field Analyzer (HFA) Program 30-2) from a normal database (n=146) and a POAG database (n=69) were analyzed to establish the precision of both an age-related and the HFA threshold-related technique for deriving the test intensity in suprathreshold perimetry. Essential Perimetry. The Field Analyzer Primer 163 pages Carl Zeiss Meditec Inc., Jena, Germany, 2002 ISBN: 0‐9721560‐0–3 As the introduction to this text declares, the book is intended to serve as ‘an introduction to and primer on clinical perimetry, particularly computerized perimetry using the Humphrey Field Analyzer’. Humphrey FDT - Frequency Doubling Technology for efficient visual field loss detection > Easy to operate and interpret: The FDT is optimized for use in both ophthalmological and non-ophthalmological settings and may be operated by healthcare workers having little or no specialty training in ophthalmology.
