Acquired color vision deficiency

Survey of Ophthalmology, 2016
Acquired color vision deficiency occurs as the result of ocular, neurologic, or systemic disease. A wide array of conditions may affect color vision, ranging from diseases of the ocular media through to pathology of the visual cortex. Traditionally, acquired color vision deficiency is considered a separate entity from congenital color vision deficiency,

Gene therapy in color vision deficiency: a review

International Ophthalmology, 2021
Color vision deficiencies are a group of vision disorders, characterized by abnormal color discrimination. They include red-green color blindness, yellow-blue color blindness and achromatopsia, among others. The deficiencies are caused by mutations in the genes coding for various components of retinal cones.

Genetics of Color Vision Deficiencies

2003
The normal X-chromosome-linked color vision gene array is composed of a single red pigment gene followed by one or more green pigment genes. The high degree of homology between these genes predisposed them to unequal recombination, leading to gene deletions or the formation of red-green hybrid genes that explain the majority of the common red-green ...

Color Vision Deficiency

Journal of Learning Disabilities, 1973
Color vision deficiency was hypothesized to be associated with impaired learning and inappropriate classroom behavior and with a higher observed frequency of referrals to programs for the educationally handicapped. Diagnostic color vision screening was conducted in 11 of 18 classrooms for the educationally handicapped (EH) and in an equivalent number ...

Color naming and categorization in inherited color vision deficiencies

Visual Neuroscience, 2006
Dichromatic subjects can name colors accurately, even though they cannot discriminate among red-green hues (Jameson & Hurvich, 1978). This result is attributed to a normative language system that dichromatic observers developed by learning subtle visual cues to compensate for their impoverished color system.

Seamless visual sharing with color vision deficiencies

ACM Transactions on Graphics, 2016
Approximately 250 million people suffer from color vision deficiency (CVD). They can hardly share the same visual content with normal-vision audiences. In this paper, we propose the first system that allows CVD and normal-vision audiences to share the same visual content simultaneously.

Color Vision, Deficiencies

1972
Color vision deficiencies are inherently intriguing. Perhaps beyond their importance for task performance based on visual discriminations is their significance for color theory. They are, as it were, nature’s “test“ cases.

A method for identifying color vision deficiency malingering

Graefe's Archive for Clinical and Experimental Ophthalmology, 2016
To propose a new test to identify color vision deficiency malingering.An online survey was distributed to 130 truly color vision deficient participants and 160 participants willing to simulate color vision deficiency. The survey contained three sets of six color-adjusted versions of the standard Ishihara color plates each, as well as one set of six ...
