The cones are special photoreceptor cells in the retina that absorb different color lights. It is most commonly caused by mutations in the CNGB3 and CNGA3 genes and is associated with severely reduced visual acuity and extreme photosensitivity, resulting in daytime blindness. Achromatopsia is recognized by the codes per the International Classification of Diseases (ICD) nomenclature Disease Achromatopsia is a rare, bilateral inherited retinal degeneration affecting all three types of cone photoreceptor cells that results in reduced visual acuity, photophobia, hemeralopia, and severe loss of color discrimination.

To date, six genes have been associated with ACHM (CNGA3, CNGB3, GNAT2, PDE6C, PDE6H, and ATF6), the majority of these being implicated in the cone phototransduction cascade. Achromatopsia. Achromatopsia is a disorder of the retina, which is the light-sensitive tissue at the back of the eye. (1)Department of Clinical Studies, School of Veterinary Medicine, University of Pennsylvania, Philadelphia, Pennsylvania, USA. Cones provide vision in bright light (daylight vision), including color vision. Achromatopsia causes extreme light sensitivity (i.e., day blindness), as well as reduced visual acuity and color discrimination.
