Q

Hypertensive retinopathy causes changes in the blood vessels supplying the eye - what are these?

A
  1. Silver wiring or copper wiring (arterioles wall become thickened and sclerosed causing increased reflection of the light)
  2. Arteriovenous nipping is where the arterioles cause compression of the veins where they cross (due to sclerosis and hardening of the arterioles)
  3. Cotton wool spots are caused by ischaemia and infarction in the retina causing damage to nerve fibres.
  4. Hard exudates are caused by damaged vessels leaking lipids into the retina.
  5. Retinal haemorrhages are caused by damaged vessels rupturing and releasing blood into the retina.
  6. Papilloedema is caused by ischaemia to the optic nerve resulting in optic nerve swelling (oedema) and blurring of the disc margins.

Q

Patient presents assymptomatic with Hba1c 44mmol/L? what is he and next steps

20
Q

if pre-diabetic patient presents a year after still assymptomatic with hba1c 57 - what to do?
