The aims of this thesis were threefold. Firstly, we wanted to establish the distribution of visual acuity (VA) and the prevalence of amblyopia and other ocular disorders in two population-based samples of 12-13-year-old children, one that had been vision-screened at preschool age and the other that had not. Secondly, we aimed to describe the ability of stereo tests to detect amblyopia and strabismus in a screening situation, and thirdly, to evaluate long-term visual outcome of treatment fo... merr amblyopia in a well-controlled group. . Just over 1,000 12-13-year-old children from each country were included.
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. .Results.
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.
