There were very few ocular opacities or posterior pole abnormalities. The visual status in the Mexican 12- to 13-year-old children tested was good. The prevalence of amblyopia was similar to that in other unscreened populations. Visual acuity, amblyopia, and ocular pathology in 12-to 13-year-old children in Northern. The purpose of this study is to elucidate the prevalence of strabismus and amblyopia in a large population of Japanese elementary school children, from Grade 1 to Grade 6, ages ranging from 6 to 12 years.
Amblyopia is caused when the brain prefers (favors) one eye to the other. The brain’s preference (liking) for one eye over the other can weaken and reduce vision in the eye that is less used. A total of 1,035 12- to 13-year-old children were examined in a field study. The examination included VA, stereopsis, cover testing, refractive retinoscopy, and examination of the red reflex and posterior pole. In cases with unexplained subnormal VA, visually evoked potential/visually evoked response was also performed.
Treatment includes correcting visual obstructions, such as cataracts and other visual abnormalities. Talk to your doctor about the best option for you. The number of children covered by the return of questionnaires was 86,531 (76.4%) of 113,254 total pupils in Grade 1 to Grade 6 in Okayama Prefecture in the year 2003. While there are no current guidelines to prevent amblyopia, vision screening can help to detect the condition at an early age. There were very few ocular opacities or posterior pole abnormalities.
