Hi,
Thank you for posting your query.
Based on her symptoms, the most likely diagnosis is idiopathic or benign intracranial hypertension (known as IIH or BIH), where the CSF pressure is raised. The normal pressure is upto 20, and as your mentioned, it is 34 in her case, which is high.
The treatment for this includes steroids, as well as diamox.
This would lower the pressure, and thus reduce the headaches, and most importantly prevent vision loss.
The fundus of eye should be examined by ophthalmologist to look for papilledema (swelling of optic disc). This would also help in monitoring the treatment response.
About 70% of patients respond to diamox and steroids. Other 30% patients may require a shunt surgery. So bottom-line is that just Migraine treatment won't work and you will need a specific treatment approach . Please discuss this option with your Doctor.
I hope it helps. Please get back if you have any follow up queries.
Best wishes,
