Diabetic retinopathy epidemiology

Brian J Song, Lloyd Paul Aiello, Louis R Pasquale
Diabetes mellitus represents a growing international public health issue with a near quadrupling in its worldwide prevalence since 1980. Though it has many known microvascular complications, vision loss from diabetic retinopathy is one of the most devastating for affected individuals. In addition, there is increasing evidence to suggest that diabetic patients have a greater risk for glaucoma as well. Though the pathophysiology of glaucoma is not completely understood, both diabetes and glaucoma appear to share some common risk factors and pathophysiologic similarities with studies also reporting that the presence of diabetes and elevated fasting glucose levels are associated with elevated intraocular pressure-the primary risk factor for glaucomatous optic neuropathy...

BACKGROUND: In sub-Saharan Africa, diabetes is a growing burden, yet little is known about its prevalence, risk factors, and complications. To address these gaps and help inform public health efforts aimed at prevention and treatment, we conducted a community-based study assessing diabetes epidemiology. METHODS AND FINDINGS: We conducted a stratified, cluster-designed, serial cross-sectional household study from 2014-2015 in the Kilimanjaro Region, Tanzania. We used a three-stage cluster probability sampling method to randomly select individuals...

AIMS: Mild cognitive dysfunction has been identified in children and adults with type 1 diabetes, but most studies have failed to find a relationship between severe hypoglycemia and cognition, despite reports of such associations in older adults with type 2 diabetes. Focusing on older adults with type 1 diabetes, we examined the associations between cognitive performance and recent episodes of severe hypoglycemia, retinal vessel diameters and the presence of micro- and macrovascular complications...

Diabetic foot is a severe public health issue, yet rare studies investigated its global epidemiology. Here we performed a systematic review and meta-analysis through searching PubMed, EMBASE, ISI Web of science and Cochrane database. We found that that global diabetic foot ulcer prevalence was 6.3% (95%CI: 5.4%-7.3%), which was higher in males (4.5%, 95%CI: 3.7%-5.2%) than in females (3.5%, 95%CI: 2.8%-4.2%), and higher in type 2 diabetic patients (6.4%, 95%CI: 4.6%-8.1%) than in type 1 diabetics (5.5%, 95%CI: 3...

AIMS/HYPOTHESIS: Haptoglobin(Hp) 2-2 genotype has been shown to increase coronary artery disease (CAD) risk in numerous type 2 diabetes studies but in only one type 1 diabetes cohort. We assessed the association of Hp2-2 with incident CAD over 26years of follow-up in 1303 Caucasian participants of the Diabetes Control and Complications Trial/Epidemiology of Diabetes Interventions and Complications (DCCT/EDIC) study. METHODS: DCCT randomized volunteers with type 1 diabetes to intensive versus conventional therapy within two cohorts: 'primary prevention' with 1-5years diabetes duration and 'secondary intervention' with 1-15years diabetes duration and early retinopathy, with or without albuminuria, but no advanced complications...

Diabetic retinopathy, a common and sight-threatening microvascular complication of diabetes mellitus, is a leading cause of blindness among working-aged adults. Medical therapies including intensive control of hyperglycemia and hypertension have been shown to reduce the incidence and progression of diabetic retinopathy. The association of dyslipidemia and treatment with statins with diabetic retinopathy is inconsistent in epidemiologic studies. However, two recent randomized clinical trials have demonstrated beneficial effects of systemic fenofibrate therapy in reducing the progression of diabetic retinopathy independently of serum lipid levels...

Alzheimer's disease (AD) and diabetes mellitus (DM) are among the most pervasive and devastating disorders that afflict people throughout the world. Although typically associated with older demographics, recent epidemiologic studies have reported parallel trends in decreasing age of onset and increasing incidence of these conditions. Promising research continues to implicate the cerebrovasculature and blood-brain barrier (BBB) as playing key roles in AD pathoetiology. Similarly, complications accompanying DM, such as diabetic nephropathy/retinopathy, cardiovascular disease, and stroke, have been rooted in vascular compromise...

Diabetic macular oedema, characterised by exudative fluid accumulation in the macula, is the most common form of sight-threatening retinopathy in people with diabetes. It affects one in 15 people with diabetes resulting in more than 20 million cases worldwide. Few epidemiological studies have been done to specifically investigate risk factors for diabetic macular oedema, although poor glycaemic and blood pressure control are associated with the presence and development of the disorder. The pathophysiological processes begin with chronic hyperglycaemia, and interplay between vascular endothelial growth factor (VEGF) and inflammatory mediators...

BACKGROUND: Diabetic retinopathy (DR) is the most common microvascular complication of diabetes and one of the main causes of irreversible vision impairment in the working-age population. Multiple studies have demonstrated the significantly high prevalence of depression in patients with DR in recent years. The progression of DR could lead to depression, whereas depressive symptoms often worsen the condition of DR. Therefore, DR is one of the causes of psychosomatic diseases, the treatment for which should combine traditional DR therapy with depression interventions...

: Reliable recognition of microaneurysms is an essential task when developing an automated analysis system for diabetic retinopathy detection. In this work, we propose an integrated approach for automated microaneurysm detection with high accuracy. METHODS: Candidate objects are first located by applying a dark object filtering process. Their cross-section profiles along multiple directions are processed through singular spectrum analysis. The correlation coefficient between each processed profile and a typical microaneurysm profile is measured and used as a scale factor to adjust the shape of the candidate profile...

The updated German clinical practice guidelines (second edition) describe the consensus recommendations for prevention and treatment of retinal complications secondary to diabetes. According to the updated numbers on epidemiology a further increase of persons affected is expected. The prevalence of diabetic retinopathy is estimated to be 9-16 % in type 2 diabetes and 24-27 % in type 1 diabetes. A prolongation of the screening interval from 1 to 2 years is recommended for those patients with a lower risk of progression, when retinopathy has not already occurred and no increased systemic risk factors are present...

Management of diabetic complications has been a worldwide major global health issue for decades. Recent studies from many parts of the world indicate improvement in this area. However, it is unknown if such an improvement is being realized in Koreans. Although there is limited information regarding diabetic retinopathy management among Koreans, recent epidemiologic studies have indicated improved screening rates and less frequent visual impairment among type 2 diabetics. Moreover, results achieved with new diagnostic and treatment modalities aimed to improve diabetic retinopathy management are encouraging for both physicians and patients...

Skin fluorescence (SF) noninvasively measures advanced glycation end products (AGEs) in the skin and is a risk indicator for diabetes complications. N-acetyltransferase 2 (NAT2) is the only known locus influencing SF. We aimed to identify additional genetic loci influencing SF in type 1 diabetes (T1D) through a meta-analysis of genome-wide association studies (N = 1,359) including Diabetes Control and Complications Trial/Epidemiology of Diabetes Interventions and Complications (DCCT/EDIC) and Wisconsin Epidemiologic Study of Diabetic Retinopathy (WESDR)...
