Temporary loss of vision in one eye. . . .

That must be scarey for you and her. I'm so sorry she has to go through those episodes.

I lost 1/2 my vision one time, seeing only 1/2 a persons face. I was told it was a visual migraine. It was stress related and I've only had it happen once, but it could be entirely different than what your daughter has going on. Will you be taking her back to Hansa? I do hope she can start going uphill again. I have a sick daughter also, so I know how hard it is to see them go through this. I wish her the best!!

It was California Cat's son who lost his peripheral vision.

I lost vision in one eye one time, last year when my migraines were REALLY bad. It was like my vision narrowed down to nothing and then I saw flashing/shimmering shapes. I'm told that was a migraine with aura, I think. It was very unsettling! I'd never had an incident like that, and it freaked me out. Luckily, my migraines have gotten a lot better. I still get blurry vision A LOT, and trouble focusing my vision.

Cranial neuritis.

CN VII Palsy (facial nerve weakness) is a form of cranial neuritis that is thought by many physicians to be common, however studies suggest that it may be seen in as few as 10% of patients with neurologic Lyme disease. However, in a patient from a Lyme endemic area or in an individual who has previously visited a Lyme endemic area, a presentation of a facial nerve palsy should lead the physician to test for Lyme disease. If the CN VII palsy affects both sides of the face, then Lyme disease should be even more strongly considered as very few diseases cause a bilateral facial nerve palsy. Typically, a cranial neuritis occurs within days to weeks of the initial infection bya tick. If patients experience abnormalities in facial sensation, the cause may be inflammation of the trigeminal cranial nerve (CN V). If central vision appears cloudy or if there is pain on eye movements, these could be signs of an optic neuritis. Pseudotumor cerebri is an intracranial increase in pressure that is not due to a tumor but because of the increase in pressure, there may be pressure on the optic nerve. This pressure could cause visual loss; in rare cases of Lyme optic neuritis from Lyme-induced pseudotumor cerebri, blindness may occur if not detected and treated early. If CN III, IV, or VI are affected, the patient may present with double vision. With involvement of CN VIII, patients may experience ringing in the ears (tinnitus), loss of hearing, vertigo, or ataxia.
