Color Vision Defects in Alcoholism–II
British Journal of Addiction to Alcohol & Other Drugs, 1971SummaryRecent data from Santiago, Chile, in which alcoholics and their female relatives showed higher incidences of overall color blindness and of blue‐yellow color blindness than was seen in controls has been interpreted to support a genetic association between alcoholism and color blindness.In this study, Farnsworth‐Munsell 100‐Hue Color Vision Tests

Color Vision Defects in Retinal Disease
Archives of Ophthalmology, 1989To the Editor. —In the December 1987 issue of theArchives, Roy and coworkers 1 accurately identify blue-yellow color vision defects in patients with sickle cell anemia using the specific and sensitive Farnsworth-Munsell 100-hue test in a well-designed, case-control study. Their interpretations of this finding, however, are not entirely accurate.

Types of Acquired Color-Vision Defects
Archives of Ophthalmology, 1957Physical light stimuli, if absorbed by the photosensitive substance or substances in the cones, generate impulses in the photoreceptors. These impulses pass through the centripetal bipolar cells and are transmitted to the ganglion cells, along whose axis cylinders they are finally conveyed to the brain. It is possible that pathological changes in this

Color and Defective Color Vision as Factors in the Conspicuity of Signs and Signals
Human Factors: The Journal of the Human Factors and Ergonomics Society, 2002The conspicuity of road traffic signs and signals for a group of observers with the color vision defect of deuteranopia is compared with that for a control group of observers with normal color vision. Conspicuity was measured by the proportion of reports of target objects detected in 300-ms presentations of projected slides of road scenes.

Color Vision Defects in Sickle Cell Anemia
Archives of Ophthalmology, 1987The Farnsworth-Munsell 100-hue test was used to compare color vision in patients with sickle cell anemia, 20/20 visual acuity, and mild to severe peripheral retinopathy, but without posterior retinal vessel involvement, with matched normal controls. Patients with sickle cell anemia had significantly more blue-yellow and mixed color vision defects and ...

Acquired Color Vision Defects in Retrobulbar Neuritis
American Journal of Ophthalmology, 1978We used the Farnsworth-Munsell 100 Hue Test to study the incidence of acquired color vision defects in 16 patients with unilateral and and seven patients with bilateral retrobulbar optic neuritis whose visual acuity had recovered to 6/12 (20/40) or better. We recorded the visual-evoked response to a pattern stimulus on the same day.

Color-defective vision and computer graphics displays
IEEE Computer Graphics and Applications, 1988A color space defined by the fundamental spectral sensitivity functions of the human visual system is used to assist in the design of computer graphics displays for color-deficient users. The functions are derived in terms of the CIE standard observer color-matching functions.

An artist with a color vision defect: Charles meryon
Survey of Ophthalmology, 1995Charles Meryon, an important artist of the 19th century, had a congenital defect in color vision. Meryon recognized this defect during his study of art, and he gradually gave up painting in favor of etching. This biographical article includes reproductions of some of Meryon's etchings and one oil painting.
