Summary
Zinc (Zn) is crucial for eye health and may prevent diabetic retinopathy. However, research on Zn supplementation
Area of Science:
- Ophthalmology
- Nutritional Science
- Endocrinology
Background:
- Zinc (Zn) is vital for physiological metabolism and ocular tissue, especially the retina.
- Zn dyshomeostasis is linked to chronic diseases like diabetes and its complications.
- Zn deficiency impacts ocular development, cataracts, AMD, and diabetic retinopathy.
Purpose of the Study:
- To review available information on zinc's role in preventing diabetic retinopathy.
- To discuss current theories and mechanisms of Zn in eye diseases.
- To explore factors influencing Zn supplementation's preventive effects on diabetic retinopathy.
Main Methods:
- Literature review of studies on zinc and diabetic retinopathy.
- Discussion of existing theories and proposed mechanisms.
- Analysis of factors affecting zinc supplementation efficacy.
Main Results:
- Zn deficiency is implicated in diabetic retinopathy pathogenesis.
- The precise mechanism of Zn's protective role in diabetic retinopathy is unclear.
- Existing data on Zn supplementation for diabetic retinopathy prevention is inconsistent.
Conclusions:
- Further research is needed to clarify zinc's role and optimize supplementation strategies for diabetic retinopathy.
- Understanding Zn's impact on ocular health is critical for managing diabetes-related eye complications.
- Factors influencing Zn bioavailability and efficacy require investigation.

01:27Diabetic Retinopathy
DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...
01:28Diabetic Nephropathy
Definition Diabetic nephropathy is a chronic kidney complication that results from prolonged hyperglycemia.Prevalence It is the most common cause of chronic kidney disease (CKD) and end-stage renal disease (ESRD) worldwide, affecting up to half of individuals with diabetes.Pathophysiology • Sustained hyperglycemia triggers multiple hemodynamic and metabolic changes in the kidney. • Early in the disease, increased renal blood flow and glomerular hyperfiltration occur due to afferent arteriolar...
01:22Diabetic Neuropathy
DefinitionDiabetic neuropathy is nerve damage caused by long-standing diabetes mellitus. It results directly from prolonged high blood sugar levels.PathophysiologyThe pathophysiology of diabetic neuropathy involves both metabolic and vascular disturbances triggered by chronic hyperglycemia.Metabolic injury: Elevated glucose levels activate the polyol pathway within nerve cells, leading to the accumulation of sorbitol and fructose. This increases oxidative stress, disrupts normal nerve...
01:26Oral Hypoglycemic Agents: Biguanides and Glitazones
Biguanides, particularly metformin (Glucophage), are insulin sensitizers that enhance glucose uptake, thereby reducing insulin resistance. Unlike sulfonylureas, metformin doesn't prompt insulin secretion, which helps to curb hypoglycemia risk. Metformin is beneficial in treating conditions like polycystic ovary syndrome due to its insulin-resistance reduction capability. The drug's primary action involves curtailing hepatic gluconeogenesis, a significant contributor to high blood glucose levels...
01:24Type II Diabetes II: Pathophysiology
PathophysiologyType 2 diabetes mellitus (T2DM ) is a chronic metabolic disorder characterized by insulin resistance and progressive pancreatic β-cell dysfunction, leading to impaired glucose homeostasis. It results from interactions among genetic predisposition, environmental factors, and metabolic stressors, such as overnutrition and a sedentary lifestyle.Insulin Resistance and Glucose DysregulationEarly T2DM involves insulin resistance in skeletal muscle, adipose tissue, and the liver.
01:26Type I Diabetes II: Pathophysiology
Type 1 diabetes mellitus arises from an immune-mediated destruction of pancreatic β-cells, resulting in an absolute deficiency of insulin. This process develops in genetically susceptible individuals when autoimmunity, environmental exposures, and immunologic dysregulation converge to trigger a targeted attack on the insulin-producing cells of the pancreas. The β-cells are located within the islets of Langerhans and are essential for regulating blood glucose by facilitating cellular uptake of...
