The Normal Visual Field on the Humphrey Field Analyzer

The Normal Visual Field on the Humphrey Field Analyzer

R S Brenton et al. Ophthalmologica.


To provide a bank of normal perimetric data, we tested the central and peripheral visual fields of 102 novice normal subjects using the Humphrey automated perimeter. All eyes used for visual field testing were first carefully examined to be sure that they were, indeed, normal. We calculated population means and standard deviations of each test location and for each decade for age. Average differential light sensitivity decreased with advancing age: -0.5 dB/decade at fixation, -0.6 dB/decade in the central (30-2) field, and -06. dB/decade in the peripheral (30/60-2) field. However, neither the slope nor the shape of the hill of vision changed with aging. Short-term fluctuation was not constant throughout the visual field, but instead was greater in the periphery than the center.
