Learn how to use the Humphrey visual field perimeter, a common tool for glaucoma diagnosis and monitoring. See examples of the most common visual field defects and how to interpret them with reliability indices and pattern analysis.
25 sie 2023 · This article discusses the process of perimetry and the interpretation of the visual field printouts (Humphrey visual field Analyzer). The history of visual field analysis dates back 2000 years, when Hippocrates first reported a case of hemianopsia.

Learn the steps and tips for proper interpretation of the 24-2 Humphrey visual field test, a common tool for glaucoma diagnosis and monitoring. The article covers the sequence of the printout, the numeric and graphical results, and the glaucoma hemifield test.
15 lut 2013 · On the Humphrey Field Analyzer (shown here), the best threshold test is the SITA-Standard. The standard test is better for early detection, while the SITA-Fast test tends to show variable results and is less sensitive. 1 The fixation losses are also noted here.
VFITM (Visual Field IndexTM) is a staging index, designed to be less affected by cataract and also to provide improved correspondence to ganglion cell loss compared to MD. VFI is approximately 100% in normal fi elds and approaches 0% in perimetrically blind fi elds.
A guide to static and kinetic perimetry, with emphasis on Humphrey fields. Learn the principles, techniques and pitfalls of visual field analysis, and how to plot and interpret the results.
