摘要

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. Early identification and treatment of DR is important since treatment is both cost-effective and reduces vision loss. The American Academy of Ophthalmologists, the American Optometric Association, and the American Diabetes Association recommend an annual dilated eye examination for all people with diabetes, and more frequent eye examinations for people with known DR. Other researchers argue that the frequency of examinations should be stratified to an individuals risk of progression and vision loss. The objectives of the research were to identify and evaluate the psychometric properties of tools used to measure health-related quality of life (HRQL) in patients receiving treatment for diabetic retinopahty (DR), and to assess the effectivenss of intervention for DR to improve HRQL. The authors conducted a systematic and comprehensive search in six electronic database and hand search reference list of review and included studies.
