Where do the horizontal and vertical meridians intersect in the visual field?

• A. Center point of fixation
• B. Edge of field
• C. Pupil center
• D. Corneal apex

Answer: (A)

The horizontal and vertical meridians cross at the center of the visual field, which is the point of fixation. This is the gaze point the viewer is directly looking at, and on the retina it corresponds to the fovea, where vision is sharpest. The edge of the field is merely the boundary of what’s visible, while the pupil center and corneal apex are anatomical landmarks and do not define where the visual-field meridians intersect.
