Does Diamox cause blurred/double vision?

I also have IIH with paplidemia and I have the blurred and double vision., but I had it before the meds. Mine is getting worse, but I don't feel it is from the meds. Go to an optometrist and have them.check your optic nerve.

I hope by now you have found an answer. IIH itself causes the vision issues and the Diamox is supposed to relieve the pressure and the vision symptoms. However, they have to work you up to the most effective dose for your case. That make time to do safely. If the vision is getting worse, you may consider doing a Lumbar Puncture to relieve the pressure immediately and use the diamox to keep it off. The lumbar puncture isn’t that bad if done with interventional radiology or x-ray fluoroscopy. I just had it done and in the ER it was awful and he wasn’t able to get it. And then the next day they used the fluoroscopy and got in and out without me feeling a thing except for the numbing thing. But if you are creating that much fluid that fast it may be time to consider a shunt. I have seen some done in the lumbar spine instead of the brain so that’s a little bit of improvement. But your case seems severe and you may need to be aggressive to avoid going blind.
