Summary
Children with diabetes have thicker corneas. Higher current hemoglobin A1C (HbA1C) levels, a marker of diabetes control, are linked to increased central corneal thickness in diabetic children.
Area of Science:
- Ophthalmology
- Endocrinology
- Diabetology
Background:
- Diabetes mellitus can affect various ocular tissues.
- Central corneal thickness (CCT) is a key parameter in ocular health assessments.
- Understanding CCT variations in pediatric diabetes is crucial for comprehensive eye care.
Purpose of the Study:
- To evaluate central corneal thickness (CCT) in children diagnosed with diabetes mellitus.
- To investigate the association between diabetes mellitus-related variables and CCT in pediatric patients.
Main Methods:
- A comparative study involving 59 children with diabetes and 38 healthy controls.
- Central corneal thickness was measured using ultrasound pachymetry.
- Statistical analyses, including ANCOVA and multivariate regression, were employed to assess the impact of age, gender, diabetes duration, HbA1C, and fasting blood sugar on CCT.
Main Results:
- Diabetic children exhibited significantly increased CCT (mean 576.9 µm) compared to controls (mean 521 µm).
- A significant multivariate regression model indicated that current hemoglobin A1C (HbA1C) level was the sole significant predictor of CCT.
- Each 1% increase in current HbA1C correlated with an approximate 9.7-13.3 µm increase in CCT.
Conclusions:
- Pediatric patients with diabetes mellitus demonstrate significantly greater central corneal thickness than their healthy counterparts.
- Current HbA1C levels, reflecting metabolic control, are independently associated with increased CCT in diabetic children.
- These findings highlight the importance of monitoring CCT in diabetic children, particularly in relation to glycemic control.

Diabetic 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...
Complications of Diabetes Mellitus
Diabetes mellitus is a chronic metabolic disorder characterized by persistent hyperglycemia due to insulin deficiency, resistance, or both. Prolonged hyperglycemia disrupts metabolic homeostasis and leads to acute and chronic complications.Acute ComplicationsAcute complications result from sudden metabolic imbalance.Diabetic ketoacidosis (DKA) mainly appears in type 1 diabetes but may also develop in type 2 diabetes, particularly under extreme stress. It arises from severe insulin deficiency,...
Diabetic 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...
Type 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...
Type 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...
Pathophysiology of Diabetes
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, suggesting a...
