Learn how to use the Humphrey visual field perimeter, a common tool for glaucoma diagnosis and monitoring. See the top 5 visual field patterns and how to interpret them based on reliability, stimulus characteristics, and density of defects.
Learn how to properly interpret a 24-2 Humphrey visual field printout for glaucoma patients. The article covers the sequence of steps, the numeric and graphical results, and the glaucoma hemifield test.
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.
10 lut 2024 · Here, glaucoma experts review the strengths and weaknesses of visual field testing, as well as provide their tips on interpreting patients’ fields. Visual Fields: An Overview. “When patients are diagnosed with glaucoma, they either have no functional deficits and a normal visual field, or they have some deficits.
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.
Learn the principles and methods of interpreting visual field tests, such as Humphrey and Goldmann, for various neurological conditions. The article covers eye anatomy, test techniques, isopters, scotomas and defect types.
