Summary
Effective prevention of diabetic retinopathy requires understanding its risk factors. Good glycaemic control and blood pressure management are key modifiable factors to prevent vision loss in diabetes mellitus patients.
Area of Science:
- Ophthalmology
- Endocrinology
- Systemic Diseases
Background:
- Diabetic retinopathy is a major complication of diabetes mellitus, leading to vision loss.
- Identifying systemic risk factors is crucial for effective prevention strategies.
- This review focuses on the relationship between diabetic retinopathy and systemic factors.
Purpose of the Study:
- To review and analyze the association between diabetic retinopathy and various systemic risk factors.
- To identify key modifiable risk factors for diabetic retinopathy progression.
Main Methods:
- A comprehensive literature search of PubMed was conducted up to May 2016.
- Inclusion criteria focused on English-language publications reporting on diabetic retinopathy and systemic risk factors.
- Selected articles were analyzed to synthesize findings.
Main Results:
- Poor glycaemic control (higher HbA1c), longer diabetes duration, and insulin use are linked to diabetic retinopathy.
- Hypertension is positively associated with diabetic retinopathy prevalence and progression.
- Myopia shows a protective effect; obesity, hyperlipidaemia, gender, and smoking have inconsistent associations. Genetic polymorphisms may increase risk.
Conclusions:
- Maintaining good glycaemic control is essential for reducing diabetic retinopathy risk.
- Effective blood pressure management is critical for preventing diabetic retinopathy progression and vision loss.
- These modifiable factors are paramount for patient outcomes in diabetes care.

Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Chronic stress has been linked to both the onset and progression of serious health conditions, including Type 2 diabetes and cancer. Type 2 diabetes, a widespread chronic illness, is closely associated with obesity and insulin resistance, both of which often worsen under stress. Studies indicate that men experiencing high levels of chronic stress face a 45% higher risk of developing diabetes compared to those with minimal stress. Stress triggers physiological responses that elevate blood...

Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...
