Achromatopsia

Definition:

Achromatopsia (Rod monochromacy/ACHM) is an autosomal recessive retinal dystrophy with a prevalence of 1 in 33,000 individuals. It is characterized by low visual aquity, photophobia, nystagmus, difficulty in color discrimination, and no recordable cone function in electroretinography with normal rod functions. The condition is caused by genetic defects affecting crucial components of the cone photoreceptor signaling.
