Understand
Diabetic retinopathy results from diabetes-related damage to the small blood vessels of the retina.
Possible symptoms
It is often silent at first; later symptoms include blurred or reduced vision, floaters and difficulty seeing in low light.
Causes and associated factors
Prolonged high blood glucose damages retinal vessels; longer diabetes duration, high blood pressure and cholesterol increase risk.
Diagnosis
Retinal photography screening can detect changes before symptoms develop.
Tests
Retinal photographs, dilated examination, OCT and sometimes angiography assess the retina and macula.
Course of the condition
Disease may progress from background changes to proliferative retinopathy or sight-threatening macular swelling.
Care options
Managing diabetes, blood pressure and cholesterol is central; laser, injections or surgery treat selected advanced disease.
When to consult
Attend regular screening and seek advice if sight worsens, becomes blurred or floaters appear.
Urgent help
Sudden visual loss, sudden blurring, a shower of floaters or a curtain over vision needs urgent assessment.
