Abstract

Purpose : To evaluate the prevalence and causes of visual impairment in preschool and school children of 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, presence and cause of decreased visual acuity.

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 the studied children, mainly in north, south, east and rural areas of the city (7%). Unilateral blindness (VA < 0,1) occurred in 0,4% and subnormal vision in 1,3 ( < 0,1 VA < 0,3). The most important cause of decreased visual acuity was refractive error observed in 37% of the children with VA < 0,7.

Conclusions : Decreased visual acuity not previously diagnosed was observed in 5% of the studied children. Refractive errors were the most important cause of visual impairment.
