DESCRIPTION (provided by applicant): Chronic Renal Insufficiency (CRI) recently was recognized as a silent epidemic affecting more than 10 million Americans. To gain understanding of the relationship between progressive renal disease and cardiovascular illness, the National Institute of Diabetes, Digestive, and Kidney Diseases (NIDDK) established the Chronic Renal Insufficiency Cohort (CRIC) Study in 2001. The principal goals of the CRIC Study are to examine risk factors for CRI and CVD events among patients with varying severity of CRI, and develop predictive models that will identify high-risk subgroups with CRI. The CRIC study did not include an eye component as part of the overall assessment of the patients. Recent studies, however, have suggested that retinal vascular abnormalities due to diabetic and hypertensive retinopathy are representative of the microvascular pathology that affects other organs such as the kidney and the heart. The presence of such retinal vascular abnormalities is associated with a markedly increased risk of progression of renal and cardiovascular disease, among others. The purpose of this ancillary study will be to obtain fundus photographs on CRIC patients to investigate the relationship between retinopathy and CRI and CVD within a population of subjects with CRI. In addition, we will assess whether fundus pathology can provide information of prognostic value regarding the progression of renal and cardiovascular disease. Potentially, non-invasive fundus photography could provide unique information about the microvasculature that would not be available through any other means. Such information could identify new risk factors that would significantly improve the predictive models to be developed through the CRIC study. Additionally, because many of the CRIC study participants are at high risk of developing significant morbidity from retinopathy due to diabetes mellitus, systemic hypertension and other vascular diseases, it is important to assess the ocular condition of patients with CRI to gain a more comprehensive evaluation of the overall pathology caused by CRI. This grant offers a unique opportunity to merge information on the ocular condition of CRIC patients with the vast amount of data that will be collected by the CRIC study, an endeavor that will yield important insight into the relationship between retinopathy and CRI.

描述（由申请人提供）：慢性肾功能不全（CRI）最近被认为是一种无声的流行病，影响了超过1000万美国人。 To gain understanding of the relationship between progressive renal disease and cardiovascular illness, the National Institute of Diabetes, Digestive, and Kidney Diseases (NIDDK) established the Chronic Renal Insufficiency Cohort (CRIC) Study in 2001. The principal goals of the CRIC Study are to examine risk factors for CRI and CVD events among patients with varying severity of CRI, and develop predictive models that will identify high-risk subgroups with CRI。 CRIC研究不包括眼睛成分，作为患者总体评估的一部分。然而，最近的研究表明，由于糖尿病和高血压视网膜病变引起的视网膜血管异常是影响其他器官（例如肾脏和心脏）的微血管病理学的代表。这种视网膜血管异常的存在与肾脏和心血管疾病进展的风险显着增加有关。这项辅助研究的目的是获取有关CRIC患者的眼底照片，以调查视网膜病，CRI和CRI和CVD在患有CRI的受试者中的关系。此外，我们将评估底眼病理学是否可以提供有关肾脏和心血管疾病进展的预后价值的信息。潜在的，非侵入性的底面摄影可能会提供有关微脉管系统的独特信息，这些信息将无法通过任何其他方式获得。这些信息可以确定新的风险因素，这些因素将大大改善通过CRIC研究开发的预测模型。此外，由于许多CRIC研究参与者的高风险是由于糖尿病，全身性高血压和其他血管疾病引起的视网膜病变的明显发病率，因此评估CRI患者的眼部疾病以获得对CRI引起的整体病理学的更全面评估的眼部疾病非常重要。该赠款提供了一个独特的机会，可以将有关CRIC患者的眼部状况的信息与CRIC研究收集的大量数据合并，这项工作将对视网膜病变和CRI之间的关系产生重要的见解。
