optic nerves were swollen; a week later she was getting double vision; Had really bad headaches from the vaccine and these are ongoing; diagnosed with idiopathic intercranial hypotension; This is a spontaneous report received from contactable reporter(s) (Consumer or other non HCP). The reporter is the patient.  A 17-year-old female patient received BNT162b2 (BNT162B2), on 28Jan2022 as dose 1, single (Lot number: FF2589) at the age of 17 years, in left arm for covid-19 immunisation. The patient's relevant medical history included: "ADHD" (ongoing), notes: ADHD, diagnosed at age 4. The patient's concomitant medications were not reported. The following information was reported: IDIOPATHIC INTRACRANIAL HYPERTENSION (medically significant) with onset 18Feb2022, outcome "not recovered", described as "diagnosed with idiopathic intercranial hypotension"; PAPILLOEDEMA (medically significant), outcome "recovered", described as "optic nerves were swollen"; DIPLOPIA (non-serious), outcome "recovered", described as "a week later she was getting double vision"; HEADACHE (non-serious), outcome "not recovered", described as "Had really bad headaches from the vaccine and these are ongoing". The events "optic nerves were swollen", "diagnosed with idiopathic intercranial hypotension", "a week later she was getting double vision" and "had really bad headaches from the vaccine and these are ongoing" required physician office visit. The patient underwent the following laboratory tests and procedures: Lumbar puncture: (18Feb2022) Unknown results, notes: she had the lumbar puncture spinal tap; has no specific results to provide; Magnetic resonance imaging: (17Feb2022) Unknown results, notes: Has gotten a few MRIs for the idiopathic intercranial hypotension and basic stuff for it. Therapeutic measures were taken as a result of papilloedema, idiopathic intracranial hypertension, diplopia, headache.  Clinical course: Patient had the 1st dose on 28Jan2022 and then on 18Feb2022 which was a few weeks after that, she was diagnosed with idiopathic intercranial hypotension and believes this to be connected to the vaccine. Caller verified she said idiopathic intercranial hypotension for the name of her diagnosis. She herself is not a HCP but states her mom is a nurse. Her neurologist thought it was a good idea to try to see how she would do without medication for a little bit and she is still having symptoms and narrowing in one of the blood vessels and is not sure if this is connected but they have not gone that far into this and the doctor says that is not really a big deal. The idiopathic intercranial hypotension is ongoing and it is actually getting worse and pretty much during the winter time it is worse due to the pressure is so much higher. She did have treatment for a little bit which was a medication Diamox and this is in an orange prescription bottle and caller verified the bottle, it does not have the lot, expiry date provide or the name of the manufacturer and the label on the bottle is a small label and is a pharmacy label. She took the Diamox for a little bit for 7 months and got off of it a few weeks ago. Patient had gotten a few MRIs for the idiopathic intercranial hypotension and basic stuff for it; went to the eye doctor which is how she got diagnosed and does not really have information but was told her optic nerves were swollen and she had to get a spinal tap; got the MRIs on 17Feb2022 and the doctor called them to say she had to have an emergency lumbar puncture because he was scared the caller was going to go blind so on 18Feb2022 she had the lumbar puncture spinal tap; has no specific results to provide. Basically a week later she was getting double vision so they sent her to the eye doctor about it; the double vision is not ongoing and she finally got the optic nerve swelling down and does not have the double vision anymore; the double vision resolved like 3 weeks after the lumbar puncture and when she started taking Diamox it would gradually get better. Patient had really bad headaches from the vaccine and these are ongoing; began like 2 days after the vaccine and she had a small headache right after the vaccine but nothing like a couple days after that; now the headaches vary during the day and are pretty persistent. No other vaccination prior to the first administration date of the suspect vaccine within 4 weeks. No one in her family has the idiopathic intercranial hypotension or has anything really else. The event require the initiation of new medication/other treatment was yes.
