PURPOSE To examine the effect of normal aging on visual field sensitivity and identify the best-fitting function for normal populations. METHODS Full Threshold standard automated perimetry data (program 24-2, Humphrey Field Analyzer) was collated retrospectively from clinically normal subjects who had previously been recruited for studies of normal visual function. One eye of each subject was randomly selected for analysis. Linear, bilinear, and simple nonlinear candidate functions of mean… CONTINUE READING
