Altered platelet function in diabetic retinopathy

The behavior of platelets aggregation has been studied in diabetics with retinopathy compared to diabetics without retinopathy and normal control groups. It has been found that there is significant increase in A.D.P. platelet aggregation% and V-max. In patient with diabetic retinopathy. The use of drugs which inhibit platelet aggregation could have important therapeutic value in prevention of diabetic retinopathy

Relation between diabetic retinopathy and total blood lipids

Total serum lipids were estimated in diabetics with and without retinopathy compared to normal non-diabetic subjects. It has been found that diabetic patients with retinopathy had significantly higher total serum lipids than diabetic patients Without retinopathy and normal control subjects. This finding supports the view that total serum lipids plays an important role in diabetic retinopathy especially exudative lesions. It also explains the value of drugs or low- fat diet which decrease the serum lipids
