Skewness and transformations of Farnsworth–Munsell 100-Hue Test scores
In the past, suggested transformations of Farnsworth-Munsell 100-Hue Test (FM 100-Hue) test scores distributions have been limited to a square root transformation. In this study, the choice of transformations of total error scores (TES) are considered by identifying a possible source of skewness. Several distributions of FM100-Hue Test TES were assessed for skewness (third moment). The error sc...
متن کاملPsychophysical Evaluation of Congenital Colour Vision Deficiency: Discrimination between Protans and Deutans Using Mollon-Reffin’s Ellipses and the Farnsworth-Munsell 100-Hue Test
We have used the Farnsworth-Munsell 100-hue (FM 100) test and Mollon-Reffin (MR) test to evaluate the colour vision of 93 subjects, 30.4 ± 9.7 years old, who had red-green congenital colour vision deficiencies. All subjects lived in Belém (State of Pará, Brazil) and were selected by the State of Pará Traffic Department. Selection criteria comprised the absence of visual dysfunctions other than ...
متن کاملColour perception in pathologists: the Farnsworth-Munsell 100-hue test.
The value of many histological stains depends on the ability of the observer to differentiate colour. This ability was assessed in 30 histopathologists and cytopathologists of varying experience using the Farnsworth-Munsell 100-hue test. As a group, the pathologists performed better than a reference population. Twenty eight subjects showed a wide ranging ability to differentiate colour: none wa...
متن کاملGenerating fast automated reports for the Farnsworth- Munsell 100-hue colour vision test
The greatest quality of the Farnsworth-Munsell (FM) 100-hue test is that it is able to indicate the presence of visual defects at early stages, so making it more widely available means more people can be saved from going blind or having their eyesight degenerate due to disease. However, the FM test is not used as often as its merits would warrant because of its main drawback – the extensive amo...
متن کاملTraumatically acquired color vision defect.
A 24-year-old man acquired a color vision defect shortly after an accident in which he struck the back of his head. Results of the Farnsworth-Munsell 100-hue test showed that the patient had poor color discrimination in both eyes. His color matches on the Nagel anomaloscope suggested a red/green disturbance. Results from increment threshold testing demonstrated on absence of the blue mechanism....
