Error in letter grade for visual screening recommendations. The article “Childhood Eye Examination” (August 15, 2013, p. 241) contained an error in the second to last sentence of the first paragraph (p. 241). The level of evidence grade for the American Academy of Family Physicians and the U.S. Preventive Services Task Force (USPSTF) recommendations to perform vision screening at least once in all children three to five years of age should be B, rather than C. The USPSTF recommends this service and has concluded that there is high certainty that the net benefit is moderate or there is moderate certainty that the net benefit is moderate to substantial. The online version of this article has been corrected.
