Refractive Errors Progression in Brazilian Low-Income School Children
Journal Title: International Journal of Ophthalmology & Eye Science (IJOES) - Year 2016, Vol 0, Issue 2
Abstract
Purpose: To assess the progression of refractive error (RE) in low-income school children in Sao Paulo, Brazil. Methods: The study population consisted of a cohort of children (11-14 years of age) from 9 randomly chosen public schools from a study performed in 2004-2005, with refraction in those with visual impairment (uncorrected distance visual acuity ≤ 20/40 in either eye). Eligible participants were those identified in the baseline study as visually impaired. Three years later, follow-up recruitment consisted of invitation for a free ophthalmic exam in the school facilities. Cycloplegic auto-refraction, cycloplegic subjective refraction and fundus examination were performed in those refracted at baseline and follow-up. Risk factors for refractive errors were investigated by administering questionnaires on family demographics, parental glasses usage and near work/outdoor activities.
