The four regions of the visual field are separated by which lines?

Explanation:
Horizontal and vertical meridians divide the visual field into four quadrants. These are imaginary lines that cross through the center of vision (the fixation point), with the horizontal meridian separating the upper from the lower field and the vertical meridian separating the left from the right field. Together they create the four regions used to describe where a visual field defect lies. Cones and rods are retina cells, the pupil and iris are eye structures, and the macula and fovea define central vision—not a method for splitting the field into four sections.
