We evaluated the effects of a food supplement containing natural extracts (Ginkgo Biloba, Bromelain, Rutin, Centella Asiatica, maritime pine bark extract and vitamins (C and E) with vasoprotective and antioxidant properties on a wide group of non-selected patients presenting with early stage diabetic retinopathy. Disease progression has been evaluated by OCT analysis on 118 patients (236 eyes) under treatment with the food supplement, and 60 patients (120 eyes) who did not take the food supplement (reference group). Results at 6 and 12 months show a non significant trend towards a slower progression in treated patients with respect to untreated ones, thus suggesting that a higher intake of vasoprotective and antioxidant agents, coupled with a tighter glycemic control, could offer some protection against this collateral pathology of diabetic patients.
