Slide 10 :

A Classification of Diabetic Retinopathy Non-proliferative diabetic retinopathy (NPDR) Mild non-proliferative diabetic retinopathy Microaneurysms Dot and blot haemorrhages Hard ( intra-retinal ) exudates Moderate-to-severe non-proliferative diabetic retinopathy The above lesions, usually with exacerbation, plus: Cotton-wool spots Venous beading and loops Intra-retinal microvascular abnormalities ( IRMA ) Proliferative diabetic retinopathy Neovascularization of the retina, optic disc or iris Fibrous tissue adherent to vitreous face of retina Retinal detachment Vitreous haemorrhage Pre retinal haemorrhage Maculopathy Clinically significant macular oedema (CSME ) Ischaemic Maculopathy

Slide 11 :

Perifoveal microaneuryisms and haemorrhages Retinal microaneurysms are focal dilatations of retinal capillaries, 10 to 100 microns in diameter, and appear as red dots. They are usually seen at the posterior pole, especially temporal to the fovea. They may apparently disappear whilst new lesions appear at the edge of areas of widening capillary non-perfusion.

Slide 12 :

Cotton Wool Spots Cotton wool spots result from occlusion of retinal pre-capillary arterioles supplying the nerve fibre layer with concomitant swelling of local nerve fibre axons. Also called "soft exudates" or "nerve fibre layer infarctions" they are white, fluffy lesions in the nerve fibre layer.

Slide 13 :

Hard exudates (Intra-retinal lipid exudates) Hard exudates ( Intra-retinal lipid exudates ) are yellow deposits of lipid and protein within the sensory retina. Accumulations of lipids leak from surrounding capillaries and microaneuryisms, they may form a circinate pattern. Hyperlipidaemia may correlate with the development of hard exudates.

Slide 14 :

Bacterial Endocarditis: Roth Spots Roth spot. The yellow arrow indicates a hemmorhage with a white central spot typical of subacute bacterial endocarditis

Slide 15 :

Pseudoxanthoma elasticum Blue sclera Angioid streaks Coronary artery calcification Systemic hypertension Intermittent claudication Arrhythmias
