RT Journal A1 Musch DC, Gardner TW T1 Diabetes and nonrefractive visual impairment: The young have it JF JAMA JO JAMA YR 2012 FD December 12 VO 308 IS 22 SP 2403 OP 2404 DO 10.1001/jama.2012.114286 UL http://dx.doi.org/10.1001/jama.2012.114286 AB Type 2 diabetes mellitus, a disease most commonly encountered in older obese persons, has become endemic in teenagers and young adults. Evidence for the increasing incidence of type 2 diabetes in youth and adolescents has been well documented.1 Given the known risk of complications from diabetes, an increase in the prevalence of these complications over time would be expected among younger diabetics. In this issue of JAMA, Ko and colleagues2 provide evidence that this is likely happening in the US population.
