Lack of naso-temporal asymmetry in the central visual field of normal subjects

Helmut Wilhelm and Manfred Fahle


Abstract

In order to test for differences between the nasal and the temporal half of the central visual field (to 10 deg eccentricity), differential light threshold, visual acuity, and vernier acuity were tested within this area. Neither method showed significant differences between nasal and temporal visual field in the mean values of all subjects. However, in some subjects, average visual field differences of 1 dB were found.
