Age changes in the visual field using the Humphrey visual field analyser

Abstract

Central and peripheral visual fields were measured for the right eyes of 45 normal subjects using the Humphrey Field Analyser. Subjects were divided into three groups according to age viz., 25 subjects of age 20 5 years, 10 subjects age 40 5 years and 10 subjects age 60 years. Computer averaging of the threshold measurements for each of the 144 points in the merged visual fields permitted comparisons of each age group. There was a slight overall decrease in sensitivity in the 40‐year‐old group and a greater decrease in the 60‐year‐old group. The mean rate of loss of sensitivity between 20 and 40 years was 0.101 dB per year and between 40 and 60 years was 0.172 dB per year.
