IIH and Arachnoid cysts

Started having symptoms in Dec 2012. Went in may 2013 to have eyes checked because my vision was going black for 30 seconds at a time. Was sent to a neuro ophthalmologist that did a surgery called optic nerves sheath fenestration to help my vision. It's been helping, but my vision has been screwing up again lately, so I'm going to see him again in September 2016 to see what's going on. I'm on several medications. I don't have a shunt cuz I don't want my head cracked open. I don't need a stint cuz my veins are normal.

If you want to know anything, ask me. Thanks!
