Data Source
The Clinformatics Data Mart database (OptumInsight, Eden Prairie, MN), a data set that has been used previously to study ocular diseases,17, 18, 19 contains detailed records of beneficiaries in a large, nationwide managed-care network in the United States. We accessed data on all beneficiaries 21 years of age or younger at their initial enrollment during January 1, 2001, through December 31, 2014.

Patient Characteristics
Among the 2240 eligible youths with newly diagnosed T1DM and 1768 with newly diagnosed T2DM, the median age at DM onset in those with T1DM and T2DM were 12 and 18 years, respectively, and the median follow-up times after initial DM diagnosis were 3.2 and 3.1 years, respectively. The maximum follow-up time was 13.0 and 12.7 years for youths with T1DM and T2DM, respectively, resulting in a maximum age of 34 years at the end of follow-up. The majority of participants with T2DM were female (83.0%).
Discussion
In this study of youths in a large US managed-care network, >20% of youths with T1DM and 7% with T2DM, with a median of >3 years of follow-up, received a diagnosis of DR. Youth with T1DM had nearly a 3-fold-increased incidence and prevalence of DR compared with youths with T2DM. For each year older a child was at initial DM diagnosis, the risk for developing DR increased among those with T1DM. Higher household net worth and female sex seemed to be protective against DR among those with T2DM.
