Summary
This study found that diabetes mellitus is associated with a higher incidence and severity of pinguecula, an eye condition. Age also contributes to pinguecula development in both diabetic and non-diabetic individuals.
Area of Science:
- Ophthalmology
- Endocrinology
- Public Health
Background:
- Pinguecula is a common degenerative condition of the conjunctiva.
- Diabetes mellitus is a systemic disease with various ocular manifestations.
- The relationship between diabetes and pinguecula has not been extensively studied.
Purpose of the Study:
- To investigate the association between age and pinguecula incidence and severity in patients with diabetes mellitus.
- To compare pinguecula grade between diabetic patients and non-diabetic controls.
Main Methods:
- A cohort of 160 patients with type 2 diabetes and 160 age-matched controls (aged 31-70) were analyzed.
- Pinguecula grade was assessed at nasal and temporal conjunctival locations using a standardized grading system.
- Multivariate logistic regression was employed to identify independent risk factors.
Main Results:
- An age-related increase in pinguecula grade was observed in both diabetic and control groups.
- Diabetic patients exhibited significantly higher pinguecula grade and prevalence on both nasal and temporal conjunctiva compared to controls.
- Diabetes mellitus was independently associated with increased pinguecula prevalence and severity, even after adjusting for age.
Conclusions:
- Diabetes mellitus may be a contributing factor to the development and progression of pinguecula.
- This study highlights a potential link between metabolic health and ocular surface conditions.
- Further research is warranted to elucidate the underlying mechanisms.

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...

Type 2 diabetes mellitus develops gradually and is often asymptomatic in early stages.Clinical ManifestationsWhen symptoms appear, they include fatigue, blurred vision, pruritus, delayed wound healing, and recurrent infections, particularly candidal infections. Peripheral neuropathy may present as numbness or tingling in the extremities. Classic hyperglycemia symptoms—polyuria, polydipsia, and polyphagia—are less common. Most patients are overweight and frequently have associated hypertension...
01:22Diabetes Mellitus: Overview and Type I Subtype
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...

01:19Type I Diabetes III: Clinical Manifestations
Type 1 diabetes mellitus typically presents with rapid-onset symptoms due to the body’s inability to utilize glucose in the absence of insulin. Since insulin is required for glucose uptake into cells, its deficiency leads to hyperglycemia and cellular energy deprivation, resulting in characteristic clinical features.Polyuria and PolydipsiaOne of the earliest, most prominent symptoms is polyuria (excessive urination). When blood glucose concentrations rise above the renal threshold, the kidneys...
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...
01:22Diabetes Mellitus: Type 2 and Gestational
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...
