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.
Each system operates with distinct IT and data infrastructures, complicating data access. At USC, the PACS system named Axis requires HFA devices to upload a PDF of each visual field, which physicians access individually from computer workstations.
15 cze 2020 · Visual field (VF) testing, although sometimes described as “torturous” by our patients, can be gratifying (and important) to interpret as an ophthalmologist, especially when done systematically. This article provides quick pearls and a framework by which you can conquer interpretation of VFs and points you in the direction of relevant ...
Look at the pattern. Look at the GHT, mean deviation, VFI, and pattern standard deviation. Compare to the previous visual fields. The visual field test is among the most important tests to learn to interpret as you begin your career in ophthalmology. Learn about the top 5 most common fields!
29 paź 2016 · Download PDF. Some novel ideas about improving visual field (VF) testing are emerging in the glaucoma research community, and even though more work is needed, they are inspiring new ways of thinking.
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?
2 lut 2016 · Purpose: To investigate the suitability of the visual field index (VFI) in different degrees of disease severity in glaucoma patients. Methods: In this cross-sectional study, we consecutively enrolled patients with primary open-angle glaucoma and glaucoma suspects (ocular hypertension).
