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.

For the purpose of serving as an Humphrey Field Analyzer: HFA II-/ Series The gold standard with comprehensive connectivity options Validated by more than 25 years of research, design and clinical experience, the Humphrey® Field Analyzer (HFA™) is the accepted standard of care to aid in glaucoma diagnosis and management. FDT and Humphrey Matrix perimetry have generally been found to be useful for screening, evaluation, and the follow-up of visual field loss in glaucoma and other ocular and neurologic diseases. Rapid screening procedures permit testing in community-based populations, children, individuals who are not able to perform conventional visual field testing, and individuals with limited access to Slideshow search results for perimetry Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising.

As the gold standard of perimetry, Humphrey ® Field Analyzer 3 (HFA3) is your trusted diagnostic partner. HFA3 delivers the interactive analysis you need, when and where you need it. Reduce visual field testing time with SITA™ Faster. Central testing to view into the macula with SITA Faster 24-2C

Therefore, it provides information regarding the location of any disease processes or lesion(s) throughout the visual pathway. Automated perimetry in both eyes with the Humphrey Field Analyzer SITA program 24-2 was used to measure the primary outcome variable. Each patient had at least two initial visual field exams at least 30 min apart to ensure reliability. 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.

Background: The Humphrey field analyser (HFA), Humphrey-Zeiss frequency doubling perimeter, and the Medmont automated perimeter (MAP) are three commonly used automated perimeters with threshold achromatic methodologies.
