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!
The normal (monocular) human visual field extends to approximately 60 degrees nasally (toward the nose, or inward) from the vertical meridian in each eye, to 107 degrees temporally (away from the nose, or outwards) from the vertical meridian, and approximately 70 degrees above and 80 below the horizontal meridian.

12 gru 2015 · Visual fields are often described to be within x degrees of fixation or expressed as a diameter such as “central 30°,” which would correspond to a circle with a 30° radius from fixation. It’s helpful to know the generally accepted “normal” visual field extent (not factoring visual sensitivity), which corresponds to the retinal anatomy.
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 ...
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.
For each eye a normal visual field extends approximately 50⁰ superiorly, 60⁰ nasally, 70⁰ inferiorly and 90⁰ temporally from central fixation. The field of vision is restricted superiorly by the upper lid and/or the bony orbital rim, and nasally by the bridge of the nose.
