Q

How is proliferative retinopathy treated?

A
  • Laser photocoagulation (destruction of peripheral ischaemic retina leads to reduction of endothelial growth factors and regression of new vessels)

A

Mainly the feet but also classic ‘glove and stocking’ distribution

24
Q

What are the clinical features of peripheral neuropathy?

A
  • Feet insensitive to trauma
  • Unpleasant chronic symptoms (paraesthesia, burning pain, numbness)
  • May be asymptomatic
  • Small muscle wasting
25

26
Q

How are ulcers prevented?

A
  • Foot screening and risk scoring

Rapid onset of neuropathic symptoms

30
Q

What are the precipitating factors for acute sensory peripheral neuropathy?

A
  • Rapid tightening of glycaemic control

- Acute metabolic upset

31
Q

Describe the progression of acute sensory peripheral neuropathy.

A
