The retinal subtypes were: 22 out of 51 achromatopsia, 9 out of 51 Leber congenital amaurosis defined as early‐onset rod‐cone dystrophy with flat electroretinogram and VEPs, 4 out of 51 severe congenital early‐onset retinal dystrophy defined as early‐onset rod‐cone dystrophy showing residual visual function in the first years of life, 5 out of 51 rod‐cone dystrophy, 5 out of 51 CACNA1F‐related congenital stationary night blindness, 4 out of 51 cone‐rod dystrophy, 1 out of 51 congenital stationary night blindness, and 1 out of 51 an atypical form of cone dystrophy. This evidence concerns the gene CACNA1F and congenital stationary night blindness.
