My 17 year old daughter at 2 o'clock in the afternoon (Aug 8) had an aura (spots with shimmery edges) that lasted for about a minute. One hour later in the blink of the eyes, she could no longer see colors (states no headache), Everything was in black and white. She was seen by an Ophthalmologist who said it was not due to the eye. He said to take her home and have her rest and if it was not better the next day to call. The next day she still could only see in black and white, She was seen by our physician and the ophthalmologist again, Blood work, MRI and further eye test were performed. Every thing was normal. That evening she could see green this lasted through out the next day. Upon waking this morning the green is gone and she is back to black and white. They referred us to a neurologist, but we are not scheduled to see her until Oct 3. She has a history of migraines and has been treated. She has been migraine free for 3 months. Her neurologist is out on medical leave. Do we wait or do we go somewhere else? I have fear of some nerve problem.
