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 · Normal Visual Field Extent. 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.
A normal visual field of each eye usually spans over 120 degrees horizontally and 90 degrees vertically. This slide shows the field of view through a normal eye. Related
20 sty 2024 · In a normal person, the field of vision should span a total width of 190 degrees. The macula, which is the central part of the retina (and is therefore important for central vision), corresponds to the central 12 to 13 degrees of your visual field.
A normal visual field is an island of vision measuring 90 degrees temporally to central Fixation, 50 degrees superiorly and nasally, and 60 degrees inferiorly. Visual acuity increases from movement discrimination in the extreme peripheral vision to better than 20/20 in the center of vision.
Use this order to interpret your Humphrey visual field every time: Confirm it’s the right patient with name and date of birth; Confirm it’s the right/left eye; Look at the reliability indices; Look at the pattern; Look at the GHT, mean deviation, VFI, and pattern standard deviation; Compare to the previous visual fields
The term visual field relates to an individual’s peripheral or “side” vision. For each eye a normal visual field extends approximately 50⁰ superiorly, 60⁰ nasally, 70⁰ inferiorly and 90⁰ temporally from central fixation.
