Color-Vision and Color-Blindness
Special public attention was called to the subject in 1875 by an enquiry into the causes of a railway accident which had taken place in Sweden, from which it appears that colourblindness was the cause of the disaster. Our author having described colour-sensations, goes on to discuss the theories of colour-perception and colour-blindness, classifying the latter defect as total and partial. Total...
متن کاملThe Spectral Luminosity Curves for a Dichromatic Eye and a Normal Eye in the Same Person.
We have recently had the opportunity to determine some visual functions of a unilaterally color-blind person, that is, one who demonstrates some form of color blindness in one eye and normal (trichromatic) vision in the other. The fact that a condition of unilateral color blindness can exist has been known since 1879.1 Cases of unilateral color blindness have been historically important, for it...
متن کاملEarly color deprivation and subsequent color vision in a dichromatic monkey.
A squirrel monkey (Saimiri sciureus) was reared for the first 4 months of life in a dim, colorless environment. Following an additional 10 months of normal visual experience, tests of color vision and spectral sensitivity were run on this animal and a control subject. The results suggest that the adult expression of dichromatic color vision does not depend on color experience during the first 4...
متن کاملGene Therapy for Color Blindness
Achromatopsia is a rare congenital cause of vision loss due to isolated cone photoreceptor dysfunction. The most common underlying genetic mutations are autosomal recessive changes in CNGA3, CNGB3, GNAT2, PDE6H, PDE6C, or ATF6. Animal models of Cnga3, Cngb3, and Gnat2 have been rescued using AAV gene therapy; showing partial restoration of cone electrophysiology and integration of this new phot...
