Diabetic retinopathy: fluorescein angiogram showing the blood vessels of the retina of a person suffering from diabetes. Diabetic retinopathy is the most common cause of preventable blindness in Western society. Its cause is obscure,although adult non-insulin dependent patients are more susceptible. Early (background) changes,as seen here,affect the small arterioles & capillaries,with the formation of microaneurysms (white spots in central macula area),haemorrhages & areas of capillary closure. Progression leads to loss of vision from exudates,oedema & ischaemia | |
