( A ) Boxplot contrasting VA for USH2A and MYOYA genotypes demonstrating worsening median VA with age, more notably with MYO7A. Number of eyes with recorded VA per genotype for each age range is numerically displayed at the top of the table above each bar. (B) Proportion of eyes by decade age ranges with VA ≥1.0 LogMAR (i.e., legal blindness) for USH2A and MYO7A genotypes. (C) Proportion of eyes by decade age ranges with VA ≤0.3 LogMAR for USH2A and MYO7A genotypes.
