Summary
Cataract is common in young type 1 diabetes mellitus patients, especially with more risk factors like diabetic retinopathy and hypertension. Early suspicion is key for timely intervention.
Area of Science:
- Ophthalmology
- Endocrinology
- Diabetology
Background:
- Type 1 diabetes mellitus (DM) is a chronic condition requiring lifelong management.
- Cataract is a known complication of diabetes, but its prevalence in young type 1 DM patients needs further investigation.
- Identifying risk factors for cataract in this population can aid in early detection and prevention.
Purpose of the Study:
- To determine the prevalence of cataract in young individuals with type 1 DM.
- To explore the association between cataract and various diabetes-related complications and risk factors.
Main Methods:
- A cross-sectional study involving 293 patients with type 1 DM.
- Evaluation of cataract presence and its correlation with diabetic retinopathy (DR), retinal laser treatment, hypertension, BMI, neuropathy, lipid profile, glycemic control, serum creatinine, and albuminuria.
Main Results:
- Cataract was observed in 19.8% of the study participants.
- Patients with cataracts were older and had a higher incidence of photocoagulation treatment, elevated serum creatinine, and hypertension.
- Cataract risk increased progressively with the number of risk factors, notably with two or more.
- Logistic regression identified associations between cataract and mild/moderate DR (OR 4.28), severe DR (OR 4.07), and macroalbuminuria (OR 2.34).
Conclusions:
- The study reveals a high prevalence of cataract in young type 1 DM patients in Southern Brazil.
- Increased disease severity in type 1 DM correlates with a higher risk of cataract development.
- Cataract should be suspected in young type 1 DM patients presenting with two or more risk factors.

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...
01:26Type 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...
01:12Type I Diabetes I: Introduction
Type 1 diabetes mellitus is a chronic metabolic disorder characterized by an absolute deficiency of insulin resulting from the autoimmune destruction of pancreatic β-cells. Although it can occur at any age, it is most commonly diagnosed in childhood, adolescence, or early adulthood. The loss of insulin production impairs cellular glucose uptake, resulting in persistent hyperglycemia and necessitating lifelong insulin therapy.Autoimmune Destruction of β-CellsThe hallmark of type 1 diabetes is an...
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...

01:22Diabetes 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...
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...
