What is Achromatopsia?

Achromatopsia (ACHM) is an inherited eye condition present from birth. It is most often characterized by poor visual acuity, nystagmus, significant to extreme sensitivity to light and absent or severely reduced color vision (color blindness). Color blindness can be so complete that many affected individuals have no comprehension of the concept of color, while others with less severe symptoms may be able to discern very saturated colors under certain lighting.

What are the symptoms?

How quickly does vision fade?

Generally speaking, the vision loss associated with ACHM is stable throughout a person's life although it can vary depending on lighting conditions.

Is it an inherited disease?

Yes; Achromatopsia is a genetically heterogenous autosomal recessive inherited eye disease. Considered rare, it is estimated that there are fewer than 1 in 30,000 people living with ACHM.

Is there a genetic test available?

Yes. The John and Marcia Carver Nonprofit Genetic Testing Laboratory has released a clinical nonprofit test for Achromatopsia. See Genetic Tests We Offer
