The subjects were initially subjected to clinical inquiry and ophthalmological exam.
Subjects then performed psychophysical tests to measure spatial contrast thresholds using sine wave gratings of different spatial frequencies and contrasts and chromatic discrimination thresholds using the Mollon-Reffin test.
For the analysis, subjects were divided into three groups according to age and compared with age-matched controls.
Ten subjects had some degree of color vision loss, which was quite severe in seven cases.
All subjects had normal luminance contr...
