| Since macular degeneration is concerned with serum, blood leakage of small
vessels, would not the use of aspirin and other blood thinners be more
cautiously used?

I don't know of any conclusive studies that proves aspirin helps
in armd. My own personal view would be that it would be more of
a chance of doing harm with armd in that, with it's anticoagulant
properties, could actually cause a higher chance of a "bleed"
in the macular (wet armd).
I'd stay with lutein and the other antioxidants- much safer.

I think the anticoagulant effects of aspirin are not a big issue in AMD.
Leakage from blood vessels, and bleeding, are difficulties encountered in
wet AMD, not the dry form which is much more prevalent.
The underlying pathophysiology of AMD is related to pigment epithelium
dysfunction. Aspirin, to the best of my knowledge, has no significant
effect on pigment epithelium function.
If a subretinal neovascular membrane which develops in wet AMD breaks and
bleeds, I suppose the bleeding could be a little more pronounced if someone
is taking aspirin. It would just make an already bad situation a little
worse.

| Aspirin effects platelet aggregation. I don't think that platelet
aggregation figures in this process.
