A 2018-11 Go to Contents Introduction 1-1 (1) Introduction This introductory section covers general information about the Humphrey® Field Analyzer 3 (HFA™3). Operating Principles A patient's visual field can be assessed by briefly projecting a spot of light (“stimulus”) of known size, brightness, and location on the inside surface of a roughly hemispherical bowl. Bowl illumination is controlled to establish a desired contrast between the stimulus and the area around it. Stimulus location and presentation timing are algorithmically varied to minimize the patient’s ability to anticipate stimulus location and timing. Stimulus brightness is algorithmically varied to determine the dimmest stimulus that can be reliably seen at each location. The resulting visual field map is used by a trained and qualified physician as an aid in diagnosis. Historically, also known as the Humphrey Field Analyzer (HFA), this instrument is the gold standard of perimetry worldwide. In addition to static perimetry, the HFA3 allows you to perform kinetic perimetry that emulates manual standard Goldmann perimetry. You can manually select kinetic isopters, or perform custom scans automatically or step by step. Intended Use The Humphrey Field Analyzer is an automatic perimeter which is.
