ABSTRACT
Purpose:
To establish the prevalence of refractive errors and ocular disorders in preschool and schoolchildren of Ibiporä, Brazil.Methods:
A survey of 6 to 12-year-old children from public and private elementary schools was carried out in Ibiporä between 1989 and 1996. Visual acuity measurements were performed by trained teachers using Snellen's chart. Children with visual acuity =0.7 in at least one eye were referred to a complete ophthalmologic examination.Results:
35,936 visual acuity measurements were performed in 13,471 children.1.966 children (14.59 percent) were referred to an ophthalmologic examination. Amblyopia was diagnosed in 237 children (1.76 percent), whereas strabismus was observed in 114 cases (0.84 percent). Cataract (n=17) (0.12 percent), chorioretinitis (n=38) (0.28 percent) and eyelid ptosis (n=6) (0.04 percent) were also diagnosed. Among the 614 (4.55 percent) children who were found to have refractive errors, 284 (46.25 percent) had hyperopia (hyperopia or hyperopic astigmatism), 206 (33.55 percent) had myopia (myopia or myopic astigmatism) and 124 (20.19 percent) showed mixed astigmatism.Conclusions:
The study determined the local prevalence of amblyopia, refractive errors and eye disorders among preschool and schoolchildren.
