Subgroup Analysis Subgroup analysis of the λ ex 436-nm dataset for location (fovea, perifovea, and near-periphery), age (young and aged eyes), and sex showed only one possibly significant difference in spectral peaks: between age groups in the near-periphery for peak S3 (643 nm for young eyes, 635 nm for aged eyes, P = 0.0351, t -test).
