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!
15 lut 2013 · Good interpretation skills start with a methodical assessment of several key plots, graphs and indices. By following a standardized process on all visual field printouts, clinicians can ensure they are accurately diagnosing ocular disease and/or detecting progression.
The normal field of vision extends to approximately 60° nasally, 90° temporally, 60° superiorly and 70° inferiorly. 3. The blind spot indicates the location of the optic nerve head—an area with no photoreceptors in the temporal part of. —.
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.
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 ...
3 cze 2021 · 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. Let’s start from the top, and work our way down to the bottom.
practice. When interpreting a standard “Central 24-2 Threshold Test,” the baseline visual field test analyzing the central 24 degrees of vision, the results are divided into 3 sections: patient and test details, displays of sensitivities across the visual field as graphical plots, and summary measures of test performance.
