Describes the storage and representation of visual field data including quality measures (fixation losses, false positive rate, etc.), foveal sensitivity, mean sensitivity, and mean deviation. Describes the storage and representation of thickness measurements such as retinal nerve fiber layer (RNFL) maps.
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!
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 ...
What is the VFI? “The VFI is a new global metric that represents the entire visual field as a single percentage of normal,” said Richard Madonna, O.D., SUNY State College of Optometry, New York. “It is based largely on the pattern deviation and weighs central points more than peripheral ones.”
29 paź 2016 · New Models for Evaluating Visual Field Tests. 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.
