Chang said the mouse with achromatopsia was found about three years ago while screening many strains of mice for vision problems as part of The Jackson Laboratory's program to develop new mouse models for human eye conditions.
Scdoris suffers from congenital achromatopsia, a hereditary condition that impairs her central vision and makes it hard for her to see the front of her team.
Total congenital colorblindness, or achromatopsia, is a scary disease in that it not only forecloses all sense of color but also makes its victims painfully sensitive to light.
The inclusion of color-related stimuli is based on the common finding of color anomia (inability to name color hues) and achromatopsia (inability to discriminate hues) in alexic patients (Albert, Goodglass, Helm, Rubens, & Alexander, 1981).
Achromatopsia is an inherited condition that presents at birth with impaired visual acuity, lack of color discrimination and extreme light sensitivity resulting in daytime blindness.
