Abstract
Purpose :
To evaluate the prevalence of refractive errors in preschool and school children in Londrina, Paraná, Brazil.
Methods :
A retrospective, cross-sectional study was performed evaluating the medical records of children who participated of Projeto Primeiros Olhares (“First Sight Program”) conducted by HOFTALON - Hospital de Olhos - Londrina “Londrina Eye Hospital”, from 2006 to 2015. Preschool and school children, 03 through 07 years of age were evaluated according to gender, uncorrected visual acuity refractive error and treatment.
Results :
2852 eyes were evaluated. The average age was 4,5 years-old, 51,8% were male and 48,2% female. Decreased uncorrected visual acuity (VA <0,7) was observed in 5% of children. Refractive errors occurred in 29%. The spherical equivalent demonstrated Hyperopia (>+1,5D) in 13% and myopia (<-0,5D) in 5%. Astigmatism (<-0,5D) occurred in 21%. High ametropias as high myopia (< -3,00D) was observed in 0,1%, high hyperopia (> 3,00D) in 2,2% and high astigmatism (< -3,00D) in 0,8%. Optical corrections were prescribed for 94% of children with refractive error.
Conclusions :
Refractive errors occurred in 29% of the evaluated children. Astigmatism and Hyperopia were the most frequent refractive errors observed
