Linear charts are the current method used in vision screenings for adolescent children. This method of screening may be unreliable in diagnosing farsightedness and astigmatism in school-aged children. Researchers published the results of their findings in the July 2010 issue of Archives of Ophthalmology . Over 2,000 children were assessed in the study. A comprehensive eye exam was given which included using a logMAR chart to measure uncorrected visual acuity. In addition, those in the study were given special drops to assess the lenses of their eyes and the curve of the corneas were measured as well. The visual acuity score accurately identified children with nearsightedness but there was no reliable cutoff score for farsightedness or astigmatism.? These findings meant that children who actually had significant farsightedness and astigmatism would not have been directed to seek treatment. Authors of the study concluded that more accurate screening methods need to be developed that will reliably detect these visual problems in children and adolescents.* Andrea Schumann Staff Writer
