I am otherwise a very healthy person and while my eyesight has not improved, it has not gotten any worse either. My concern is that I'm being told that I need to start on a lifetime treatment of coumadin. This is a minimal variation from normal. Anyway, the only effective anticoagulants currently are aspirin and coumadin. I certainly would recommend aspirin.
Some patients take a very small dose of coumadin.
You must know that the side effects of coumadin are dose related. A small dose rarely causes side effects or excessive bleeding. Some patients take aspirin and one mg of coumadin. It would be hard to advocate systemic anticoagulation. However, I doubt you are interested in a stroke.
