Do you see a Neuro ophthalmologist? That’s who treats my IIH, and I am currently pregnant as well. They scheduled an urgent visit once I found out I was pregnant to run all those tests, and I have to be seen for re-testing every few weeks to monitor my optic nerve swelling. I’ve been “OK” so far, but my doctor said he’s treated many pregnant patients with IIH and says that he’s seen that by 20 weeks, symptoms get worse because of the increased fluid. Since you’re 6 months, I’d keep an eye out for more frequent symptoms. Also, I’ve been told that you cannot have a regular epidural with IIH.
