Color-discrimination threshold determination using pseudoisochromatic test plates
We produced a set of pseudoisochromatic plates for determining individual color-difference thresholds to assess test performance and test properties, and analyzed the results. We report a high test validity and classification ability for the deficiency type and severity level [comparable to that of the fourth edition of the Hardy-Rand-Rittler (HRR) test]. We discuss changes of the acceptable ch...
متن کاملPoorer color discrimination by females when tested with pseudoisochromatic plates containing vanishing designs on neutral backgrounds.
It might be expected that normal trichromatic females would perform as well as normal trichromatic males of the same age when tested with standard clinical color-vision tests that use pseudoisochromatic vanishing designs on neutral gray backgrounds such as the Hardy-Rand-Rittler (HRR) pseudoisochromatic plates and the Neitz Test of Color Vision (NTCV). Here 2966 children aged 6-13 years from fo...
متن کاملA pseudoisochromatic test of color vision for human infants
Despite the development of experimental methods capable of measuring early human color vision, we still lack a procedure comparable to those used to diagnose the well-identified congenital and acquired color vision anomalies in older children, adults, and clinical patients. In this study, we modified a pseudoisochromatic test to make it more suitable for young infants. Using a forced choice pre...
متن کاملMeasuring short-wavelength-sensitive cone discrimination thresholds using pseudoisochromatic figures displayed on a color monitor.
PURPOSE To simplify the testing of short-wavelength-sensitive (SWS) cone function in the clinic. METHODS SWS-cone discrimination thresholds were measured along the tritan axis using pseudoisochromatic figures displayed on a color monitor. A circular 6 degrees field, containing spatially discrete patches of varying sizes and luminances, was presented on a background. A subset of patches formed...
متن کاملColor vision in horses (Equus caballus): deficiencies identified using a pseudoisochromatic plate test.
In the past, equine color vision was tested with stimuli composed either of painted cards or photographic slides or through physiological testing using electroretinogram flicker photometry. Some studies produced similar results, but others did not, demonstrating that there was not yet a definitive answer regarding color vision in horses (Equus caballus). In this study, a pseudoisochromatic plat...
