Note: Prevalence was calculated from all children screened for the first time in Year 1 (n = 2519) and in Year 2 (n = 2292). If a child had more than 1 eye problem, they were counted in each applicable disorder category. Other problems that we identified were 6 cases of opaque media, 5 cases of limited/overactive ocular motility, 3 cases of nystagmus, 2 cases of optic nerve abnormality and 1 case of narrow angles.
