Don't know if you are still looking for information on high-or low flow bypass but here's what I typed in "high- or low-flow bypass for aneurysm" into google and some stuff came up. No way I can even attempt to tell you what they were saying but if you type that into google you should get some stuff.

Have you been told that its pressing on your optic nerve? I had visual tests to get a base line for my vision (don't have any issues now) so they could compare as time goes on.

Good luck with your search
