N2 - A device that maintains steady fixation while plotting the visual field of an eye with a large central defect is presented. The device is composed of multiple adjacent pinhole tubes mounted on an eye shield and placed in front of the seeing fellow eye. The device constricts the visual field of the fixating nontested eye to preserve only the central 3°, thus not interfering with the visual field of the tested eye. We tested 3 healthy volunteers. with simulated visual field defects and more than 100 patients with unilateral loss of central vision. The use of this device allowed us to plot visual field defects with clear-cut borders while no meaningful results could be obtained without it. We found this device to be efficient, simple to use, and suitable for all varieties of perimetry.
