diabetic retinopathy Flashcards
1
Q
diabetic retinopathy pathophysiology
A
damage to retinal blood vessels
increased permeability - leaks, blot haemorrhages, hard exudates, microaneurysms
damage to nerve fibres - cotton wool spots
neovascularisation
2
Q
grading of diabetic retinopathy
A
background - microaneurysms, retinal haemorrhages and cotton wool spots
pre-proliferative- venous bleeding, multiple blot haemorrhages, IMRA
proliferative - neovascularisation, vitreous haemorrhage
3
Q
complications of diabetic retinopathy
A
vision loss
retinal detachment
vitreous haemorrhage
rubeosis iridis - neovascular glaucoma
optic neuropathy
cataracts
4
Q
management of diabetic retinopathy
A
diabetic control
if proliferative - pan-retinal photocoagulation
anti-VEGF
surgery - vitrectomy
