1. Classification and treatment of Diabetic Retinopathy

2. Diabetic Retinopathy can be divided into various sub-types
Background diabetic retinopathy
Diabetic maculopathy
Proliferative diabetic retinopathy

3. Mild non-proliferative diabetic retinopathy
Microaneurysms commonest
Rarely macular oedema

4. Background Diabetic Retinopathy

5. Moderate non-proliferative diabetic retinopathy
Microaneurysms
Cotton wool spots
Superficial flame shaped haemorrhages
Venous changes
IRMA

7. Severe non-proliferative diabetic retinopathy
IRMA
Venous beading
Blotch haemorrhages
In more than two quadrants of retina

9. Management of severe NPDR
ETDRS results suggest that PRP may be considered
Associated risk factors :-
Type 1 diabetes mellitus
Arterial hypertension
Pregnancy
Lack of compliance
Diabetic nephropathy

11. Classification of diabetic maculopathy and macular oedema
Focal exudative macular oedema
Diffuse exudative macular oedema
Ischaemic maculopathy
Mixed forms

12. Diabetic maculopathy causes 90% of visual loss from diabetes - but these patients retain navigating sight

13. Treatment of focal exudative macular oedema

20. Treatment of diffuse macular oedema

24. Treatment of ischaemic diabetic maculopathy

27. Proliferative Diabetic Retinopathy
New vessels elsewhere (NVE)
New disc vessels (NVD)
High risk proliferative diabetic retinopathy
- New vessels ( NVE/NVD)
- Preretinal haemorrhage

28. Proliferative retinopathy causes total blindness in 70% of untreated eyes after 5 years onset of neovascularisation

30. Treatment of NVE Mild NVE – focal treatment
Severe NVE – PRP (600 – 800 burns)

33. Treatment of NVD
PRP – 3000 burns

36. New Old
