Am eating my words now. I forgot about that problem after Trimethoprim and took it for another ecoli UTI June 14th and I think I have a comment on here but cant find it: June 16th I started to see something similar to virtual snow but it isnt quite the same. I already have narrow angle glaucoma with iridotomy, and floaters (as well as other illnesses) and I still have it. I have the floaters, they seems a few more but used to them but this seeing thousands if not millions of tiny tiny little squiggly specks has not gone away; I get it day and night and eyes closes or open in dark, dim or bright light. I had a glaucoma check during this time and good news but Optometrist did not comment when I told her about this vision issue - she thought stress, then thought migraine (I have migraine aura most of life, its not that)... I cannot prove it was the Trimethoprim but have read about other eye issues although "rare." This is the icing on the cake for me.... its so difficult to describe and am thankful I can still "see" but this constant moving veil is really getting me down and will never take this med again just in case: have no idea what to do next, N.P. has no idea! I know it could be worse but have enough other things to contend with as everyone else on here... and I wish I had the biggest magic wand in the world to wave, make us feel better, and enjoy life to the full 🙁
