Which finding indicates proliferative diabetic retinopathy?
Answer and explanation
Correct answer: C. New vessel formation (neovascularisation) at the disc or elsewhere
- Step 1: Retinopathy is graded from background to proliferative disease. Step 2. Neovascularisation arises from ischaemia and risks vitreous haemorrhage and traction detachment, and is treated with laser or anti-VEGF injection. Answer: New vessel formation (neovascularisation) at the disc or elsewhere. Why not the others: Microaneurysms and dot haemorrhages are features of background retinopathy. Arteriolar narrowing is a hypertensive change.
