Summary
This study found that diabetes mellitus is not a risk factor for open-angle glaucoma (OAG). Researchers examined over 3800 participants, and diabetes did not increase the likelihood of developing OAG.
Area of Science:
- Ophthalmology
- Endocrinology
- Epidemiology
Background:
- Open-angle glaucoma (OAG) is a leading cause of irreversible blindness worldwide.
- Diabetes mellitus is a common metabolic disorder with various systemic complications.
- The relationship between diabetes and OAG risk remains a subject of investigation.
Purpose of the Study:
- To determine if diabetes mellitus is a significant risk factor for the development of open-angle glaucoma (OAG).
Main Methods:
- A prospective, population-based cohort study involving 3837 participants aged 55 years and older from the Rotterdam Study.
- Ophthalmic examinations including intraocular pressure, visual field testing, and optic disc photography were conducted at baseline and follow-up.
- Diabetes mellitus was defined by medication use or elevated glucose levels; OAG diagnosis was based on optic disc and visual field criteria.
Main Results:
- Over a mean follow-up of 6.5 years, 87 participants developed incident OAG (iOAG).
- The relative risk of iOAG associated with diabetes at baseline was 0.82 (0.33-2.05).
- After adjusting for multiple factors, the relative risk of iOAG remained non-significant at 0.65 (0.25-1.64).
Conclusions:
- Diabetes mellitus was not identified as a risk factor for open-angle glaucoma in this population-based cohort.
- These findings suggest that diabetes does not contribute to the incidence of OAG.

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...
01:27Open Angle Glaucoma: Treatment
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

01:25Glaucoma: Overview
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
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...
01:25Type II Diabetes Mellitus III: Clinical Manifestations and Diagnosis
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...
01:26Type II Diabetes I: Introduction
Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder characterized by insulin resistance, in which target tissues such as the liver, muscle, and adipose tissue respond poorly to insulin. It is also associated with inadequate compensatory insulin secretion, where pancreatic β-cells fail to produce sufficient insulin. Together, these abnormalities lead to persistent hyperglycemia.EtiologyT2DM develops through a complex interaction of genetic predisposition and environmental or...
