This is the ninth in a series of articles based on presentations at the American Diabetes Association's 67th Scientific Sessions, 22–26 June 2007, Chicago, Illinois, that discuss aspects of diabetic retinopathy.
A number of studies presented at the ADA meeting addressed aspects of the clinical epidemiology of diabetic eye disease. Saaddine et al. (abstract 819) used National Health Interview Survey and census data to project that the prevalence of diabetic retinopathy in the U.S. will increase from 5.8 to 17.7 million people from 2005 to 2050, with retinopathy threatening vision projected to increase from 1.3 to 3.7 million over this time. (Abstract numbers refer to the American Diabetes Association Scientific Sessions, Diabetes 56 [Suppl. 1], 2007.) Cataracts, Saaddine reported, will likely more than double in prevalence, and there will be a 12-fold increase in the number of Hispanics with diabetes
Emanuele et al. (abstract 95) reported the presence of clinically significant macular edema in 11% of 536 diabetic individuals, with prevalence more than twice as great in Hispanic and African-American as that in non-Hispanic White patients. In multivariate analysis, diastolic blood pressure, duration of diabetes, and the urine albumin-to-creatinine ratio were additional contributory factors. Sibal and Home (abstract 832) studied 404 type 1 diabetic patients followed for 9 years, finding retinopathy to be associated with higher diastolic
