A new technology assessment has been released by the Agency for Healthcare Research & Quality (AHRQ): Measuring Health-Related Quality of Life for Patients With Diabetic Retinopathy.
Diabetic retinopathy (DR) is a leading cause of vision loss in the United States and occurs as a result of pathologic changes of the retinal vasculature. In 2005–2008, the estimated crude prevalence among Americans over the age of 40 with diabetes was 28.5 percent. Although the prevalence of vision-threatening DR is approximately 4.4 percent, the number of affected Americans 40 years or older is expected to triple from 1.2 million in 2005 to 3.4 million in 2050. The prevalence and severity of DR increases with the duration of diabetes; however, it is inversely correlated to glycemic and blood pressure control. Moderate vision loss is most commonly related to retinal leakage within the macula, while severe vision loss usually occurs as a result of neovascularization (proliferative diabetic retinopathy; PDR) with subsequent hemorrhage or fibrosis.
