Retinal Bleeding Moments

From what is available for reading ... One can improve blood supply to the eyes.... A diabetic friend recently suffered retina bleeding... Eyes nourishing supplements would probably aggravate the bleeding.. Now as I'm but merely a quack doctor, my layman's intincts do advise... Should refrain from berries products that supposedly inproves blood supply... When his lovely wife gives him Goji berries, the quack in me recoils... Goji berries are much touted as being good for nourishing the eyes... But I think those research scientists probably were thinking of healthy eyes... If Goji berries and its kind, really improves blood supply to nourish the eyes... I would think it is not advisable to take supplements that nourishes the eyes.. For the nourishing effects comes after the heels of improving blood supply... This man in hospital with his retinal bleeding eyes, he's my poor suffering friend... Alas! Is this a case of too much tender loving care for a loved one there?
