Diabetic Retinopathy

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...

Type II Diabetes Mellitus III: Clinical Manifestations and Diagnosis

Type 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...

Diabetic Nephropathy

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...

Complications of Diabetes Mellitus

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,...

Diabetes: Symptoms, Diagnosis, and Complications

Diabetes: Symptoms, Diagnosis, and Complications

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is based on...

Hyperglycemia

Hyperglycemia

Hyperglycemia is an abnormally high blood glucose level. It is diagnosed by fasting glucose ≥126 mg/dL, 2-hour oral glucose tolerance test (or OGTT) ≥200 mg/dL, random glucose ≥200 mg/dL with symptoms, or HbA1c ≥6.5%. However, HbA1c results may be unreliable in certain conditions, such as anemia or hemoglobinopathies, and the diagnosis should be confirmed unless classic symptoms are present. Postprandial hyperglycemia is typically considered significant when glucose levels exceed 180 mg/dL two...

Summary

Early screening and patient education are vital for preventing vision loss from diabetic retinopathy (DR). Effective DR management requires healthcare collaboration, though severe cases can still lead to vision loss despite treatment.

Background:

Diabetic retinopathy (DR) is a leading cause of preventable blindness.
Early detection through screening is crucial for preserving vision in diabetic patients.
Patient education on diabetes management is essential for DR prevention and control.

Observation:

Two cases of proliferative diabetic retinopathy (PDR) with severe complications are presented.
Complications included vitreous hemorrhage, traction retinal detachment, and neovascular glaucoma.
One patient experienced irreversible vision loss despite treatment, while another improved post-surgery.

Findings:

Effective screening for DR relies on interprofessional collaboration among healthcare providers.
Prompt detection of DR allows for timely intervention, mitigating severe visual impairment.
Surgical intervention, such as pars plana vitrectomy, can restore vision in some advanced PDR cases.

Implications:

Highlights the critical need for robust DR screening programs and patient education initiatives.
Underscores the importance of a multidisciplinary approach in managing diabetic eye disease.
Emphasizes the potential for vision recovery with appropriate and timely surgical management in complex DR cases.
