Diabetic Retinopathy01:27

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...

Summary

Ultra-widefield swept-source optical coherence tomography angiography (SS-OCTA) effectively detects peripheral ischemia and neovascularization in diabetic retinopathy (DR). This advanced imaging helps refine DR staging and guide timely interventions.

Area of Science:

  • Ophthalmology
  • Medical Imaging
  • Diabetic Retinopathy Research

Background:

  • Diabetic retinopathy (DR) is a leading cause of vision loss.

  • Standard imaging techniques may not fully capture peripheral retinal changes in DR.
  • Early detection of peripheral lesions is crucial for effective DR management.
