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.
Normal vision field. Glaucoma is a disease of the optic nerve, and one of the best ways to measure disease of the optic nerve is to assess its function with visual field testing. A normal visual field of each eye usually spans over 120 degrees horizontally and 90 degrees vertically.
