Washington, DC, United States, 2005/08/16 - New National Institutes of Health study finds that vision screenings identify just 37-68% of children with a vision problem needing correction.
- A major National Institutes of Health study released today found that common vision screenings are failing to identify large numbers of children with vision problems needing correction. The study was published in the August, 2005 edition of Investigative Ophthalmology and Visual Science.
“This study makes it clear why children need a comprehensive vision examination before starting school,” said Joel Zaba, OD, MA. “The study shows that just 37 percent to 68 percent of vision problems are detected by vision screenings,” said Zaba, an optometrist and child development expert. “Our children simply deserve better odds when dealing with one of the most important tools they have for learning.”
The Vision in Preschoolers (VIP) study sought to compare the effectiveness of nurses and laypersons in administering preschool vision screening. Although it is the most commonly used method of identifying children with vision problems, vision screening is far less comprehensive and far less effective than an eye exam by an optometrist or ophthalmologist.
While the study found little variance in the performance of nurses and laypersons, both groups failed to identify large numbers of children with problems. The worst performing tests, for example, caught just 37 percent of children with a problem, the best just 68 percent.
Screening Tool Children Caught
Retinomax Autorefractor 68% 62%
SureSight Vision Screener 64% 61%
Linear Lea Symbols 49% 37%
Stereo Smile 45% 40%
Amblyopia is the leading cause of vision loss in young Americans, affecting 500,000 preschoolers. Early treatment is critical if vision loss is to be avoided. Undiagnosed vision.
problems can also cause problems in school. According to the CDC, “impaired vision can affect a child's cognitive, emotional, neurologic and physical development by potentially limiting the range of experiences and kinds of information to which the child is exposed.”
