ATLANTA — Decreased vision is uncommon in preschool-aged children in both white and African-American populations, the Baltimore Pediatric Eye Disease Study found.

Michael X. Repka, MD, said at the annual meeting of the American Academy of Ophthalmology that a little more than 1% of white children and 2% of African-American children have vision that is below the accepted standard on first presentation.

Only children who could read an eye chart were able to participate in the visual acuity test. These children included about 1,300 children out of the approximately 2,500 children in the overall study; they were between 48 months and 71 months of age.

"There's no reason to expect that a 3-year-old or a 2-year-old will differ over this age range than a 5- or 6-year-old, so we should still be able to get reasonable estimates for prevalence," Dr. Repka said.
