Yes I have IIH without having papilledema (swollen optic discs common to IIH) - my diagnosis is confirmed with a lumber puncture with an opening pressure of 38 cm/h2o. it may just be that i have not yet developed pap yet , but so far my eyes are fine.
IIH is not necessarily linked to migraines - although sometimes the headaches are misdiagnosed as migraines. If you are strongly concerned that you may have IIH you would want to speak to your GP about seeing a neurologist and getting an MRI (to rule out other causes) and then possibly a lumber puncture if they thought it was then required.
