Hi,
This appears to be a neurologic condition however, with regards to her eyes, was there no preexisting eye problem?
Weakness and visual symptoms may also have hormonal imbalance and nutritional deficiencies as differentials. Was your child assessed along this line?
This sounds like a case of complex migraine. I would assume a cranial CT Scan was done. If yes, what were the results? Did the cranial scan showed normal results?
I had severe headaches, blurred vision at times and had sleep problems as well. What caused it for me was being exposed to too many devices in my house that gave off radiation -- my cell phone, wifi wireless router on my computer and even a strong cordless phone. Check out electro hyper sensitivity anywhere on the web -- it really could be the cause.
I am happy to answer any further questions -- i know that it seems far fetched -- but I really got my life back. I hope she feels better.
