Now on my second bottle it is the same, no worse, and I have not heard from my LLMD. Any one here have any experience with this phenomena?

Also taking ketek, ceftin and artemisinin, but don't think these are the cause.

My theory is that when Babesia infects your red blood cells, it excretes a protein on the surface that makes the cells sticky. These infected cells clog the fine capillaries in your brain and eyes, so you don't get good circulation and fluid flow in and out of these regions. (This is consistent with what you feel when you start Mepron -- huge head and neck pressure.) I think the yellow pigment in Mepron collects in eye fluids, and this discolors your vision, until the inflammation clears.

I've been taking Mepron for six months now, and I no longer have the vision discoloration. But it's very disconcerting when it first happens.
