CNGA3, CNGB3, and CRB1 were associated with high hypermetropia, remaining high with time in CRB1. In contrast, Congenital Stationary Night Blindness (CSNB) and Blue Cone Monochromacy (BCM) demonstrated high myopia, worsening over time in CSNB, with an increasing rate in high myopia from 51.5% to 69.7% from first to last visit. This evidence concerns the gene CNGA3 and Hypermetropia.
