Details
Achromatopsia (AMAL form) can cause day-blindness, total colorblindness, and limited vision particularly with regards to shapes and details of objects. For some breeds with this form of achromatopsia, there may be a late-onset. Please note that there are several forms of this disease that have tests available.
Details 2
Achromatopsia is an autosomal recessive disease characterized by the loss of cone photoreceptor function that results in day-blindness, total colorblindness, and decreased central visual acuity. (Yeh et al., 2013)
