[Age-related changes in the normal visual field using colored targets]

The authors evaluated the influence of aging on the normal visual field sensitivity and the color visual field sensitivity. The central 5 degrees visual field of 259 normal subjects (ages 10 to 79) was evaluated with Program Macula of the Humphrey Field Analyzer. Visual field sensitivity remained constant, irrespective of age, until 40 years. In contrast, sensitivity decreased linearly with aging after 40 years. The age-related decline of visual field sensitivity was most remarkable using a blue target. Visual field sensitivity gradually decreased toward the peripheral retina measured by white, red and green targets. However, using a blue target, at 1 degree-2 degrees locations from the fovea, sensitivity was the same as foveal sensitivity. There were no statistically significant differences of visual field sensitivity between the lower half of visual field and the upper half, and between the temporal half and the nasal half. At all test locations, the ordering of visual field sensitivity was white > red > blue > green target.
