For many years now... my now 20 year old daughter will tempoarily lose her vision when she gets hot. We have been to a neurologist / optho-neurologist and other doctors and they are baffled as to what the reason is behind this. Some think she could be having migraines but she has no pain associated with this. Her heart is fine, blood pressure was good.

When these episodes happen she gets a cool feeling or a flushed feeling in her face...she is completely aware of what is going on around her except she can not see. This last from a few seconds to up a minute.

Anyone else experience this or point me into the right direction for help.

Thanks,
