Amblyopia (often called a lazy eye) means that vision in one eye does not develop fully during early childhood. Amblyopia is usually a correctable problem if it is treated early. Late treatment can mean that the sight problem remains permanent. A squint (strabismus) is one of the most common causes of amblyopia. 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. The School Health Law requires that all pupils in Grade 1 to Grade 6 be examined for vision and eye problems.
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 Swedish population had been vision-screened at preschool age. 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.
