Summary
Diabetic retinopathy involves vascular changes, leading to blindness. Leukocyte adhesion in retinal capillaries (retinal leukostasis) is an early event in diabetic retinopathy development and a potential therapeutic target.
Area of Science:
- Ophthalmology
- Diabetology
- Vascular Biology
Background:
- Diabetic retinopathy is a leading cause of blindness in working-age adults.
- Early stages (nonproliferative diabetic retinopathy) involve vascular abnormalities like pericyte loss and capillary occlusion.
- Ischemia from capillary non-perfusion drives proliferative diabetic retinopathy and vision loss.
Purpose of the Study:
- To review the role of leukocytes in diabetic retinopathy pathogenesis.
- To discuss retinal leukostasis as a potential therapeutic target.
Main Methods:
- Literature review of current research on leukocytes and diabetic retinopathy.
- Analysis of evidence linking leukocyte-endothelial interactions to capillary occlusion.
Main Results:
- Leukocyte-endothelial cell adhesion (retinal leukostasis) is implicated in early capillary non-perfusion.
- Leukocytes in diabetic patients exhibit increased activation and adhesion.
- Retinal leukostasis is associated with vascular non-perfusion and diabetic retinopathy development.
Conclusions:
- Retinal leukostasis is a key early event in diabetic retinopathy.
- Targeting leukostasis offers a promising new strategy for diabetic retinopathy treatment.

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...
01:28Diabetic 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...
01:21Structure and Function of Leukocytes
An adult in good health typically has between 4,500 and 11,000 leukocytes, or white blood cells, per microliter of blood, which constitutes about 1% of the total blood volume. Unlike red blood cells, white blood cells contain a nucleus and other cellular organelles but do not have hemoglobin. Most white blood cells reside in connective tissues, particularly in lymphatic organs such as the lymph nodes, with only a small fraction present in circulating blood.

01:27Disorders of Leukocytes
Leukocyte disorders can lead to either leukopenia, characterized by an abnormally low leukocyte count, or leukocytosis, marked by a very high leukocyte number.
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune system...

01:31Diabetic Foot Ulcer
Definition A diabetic foot ulcer (DFU) is a chronic, non-healing wound that develops in individuals with diabetes. It typically occurs on pressure-bearing areas such as the heel, metatarsal heads, or hallux, and carries a high risk of infection and amputation.Pathophysiology • The development of DFUs can be explained by four interconnected mechanisms: neuropathy, ischemia, infection, and impaired wound healing. • Neuropathy is the most common factor. Sensory neuropathy reduces pain perception,...
01:22Diabetic Neuropathy
DefinitionDiabetic neuropathy is nerve damage caused by long-standing diabetes mellitus. It results directly from prolonged high blood sugar levels.PathophysiologyThe pathophysiology of diabetic neuropathy involves both metabolic and vascular disturbances triggered by chronic hyperglycemia.Metabolic injury: Elevated glucose levels activate the polyol pathway within nerve cells, leading to the accumulation of sorbitol and fructose. This increases oxidative stress, disrupts normal nerve...
