Definition. The field of vision is that portion of space in which objects are visible at the same moment during steady fixation of gaze in one direction. The monocular visual field consists of central vision, which includes the inner 30 degrees of vision and central fixation, and the peripheral visual field, which extends 100 degrees laterally ...
The visual field is "that portion of space in which objects are visible at the same moment during steady fixation of the gaze in one direction"; [1] in ophthalmology and neurology the emphasis is mostly on the structure inside the visual field and it is then considered “the field of functional capacity obtained and recorded by means of ...

28 paź 2016 · The visual field is the portion of space visible to a single stationary eye. The normal visual field extends 90° temporally, 70° inferiorly, and 60° nasally and superiorly [1]. Visual field testing involves assessment of contrast threshold at multiple points in the field.
1 sty 2024 · The term receptive field refers to the region of visual space where changes in luminance influence the activity of a single neuron. Also known as the classical receptive field (CRF).
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 ...
