My SIL has suffered from migraines for years. Just before Thanksgiving she went to an opthamologist for her regular exam. She began experiencing severe headaches after that appointment and began losing vision.

They did an MRI thinking it might be MS and optic neuritis, but no lesions. After all this time, they did an angiogram ? of the eye, and they can tell that her optic nerve is damaged, and the sight she has lost is gone for good. They tell her it could be lupus or MS, but nothing is showing up on the tests for now.

They are sending her tests to specialists in SLC, but until then, does anyone have any experiences similar to this that may shed some light on her condition?
