   15 cze 2020 · Look for a cluster of two or more defects, and look at the summary data, including mean deviation, pattern standard deviation, visual field index (VFI) and the glaucoma hemifield test. (EyeWiki does a great job of simplifying this.) It’s also important to identify any VF correlation with a structural defect (on the opposite side of the nerve).

   Visual fields are one of the primary diagnostic imaging tests used to assess glaucoma and other optic neuropathies. The DICOM Ophthalmic Visual Field (OPV) file format is the gold-standard for saving and communicating visual field results. Table 2. Examples of visual field devices, testing strategies, patterns, and reported metrics.

   At the May 2009 annual meeting of the Association for Research in Vision and Ophthalmology in Ft. Lauderdale, Fla., several research groups investigated the clinical utility of the new parameter—the visual field index (VFI)—to detect progression of the visual field over time. What is the VFI?

   Visual field index (VFI). This index expresses the visual field status as a percent of a normal age-adjusted visual field. Greater weight is given to points closer to fixation to adjust for gangion cell density and visual function. The index may also be less sensitive to cataract and media changes. Mean deviation (see section 4.3). The overall ...

   3 cze 2021 · Visual field testing is essential for diagnosing and managing glaucoma, neurological diseases, and even some retinal diseases. This article focuses on reviewing the meaning of indices and markers on a Humphrey Visual Field so we can better determine reliability and gain confidence in understanding our patient’s visual field loss.
