I get these, too--can lose most of my vision--not that it's "blacked out" but just "gone". not black, but gone. It can effect one side of the vision or the middle (that's really funny, to see your husband but he has no head LOL!). I do not have pain with mine.
I do have spots in my vision that do not ever go away. There are now 3 of them, in a triangle, in my right eye. The opthamologist says he can see them. He sent me to a retinal specialist, but there isn't any cause for alarm yet--but they did tell me to watch out for signs of retinal detachment, because that's the next step. It seems that the vitreous gel of the right eye has liquified and that's a "problem" LOL...
Leave it to me to be the "one" with the problem.. haha
I have these too. I get the "blindspots" which chicibug described as not black, just gone. I too have the headless husband syndrome LOL!
Sometimes instead of the blindspots, I have "snow vision" like tv snow. Like everyone else I've been told by my Ophthalmologist that these are aura migraines. I've been given imitrex and if I take it as soon as I start losing spots of vision, seeing spots or just feel the pain coming, it will often stop the migraine dead in its track and leave me with the same mild headache I have all the time.
So I'm really contributing nothing to the conversation, except this: When I get the blindspots, I have traveling numbness. Often this starts with one half of my hand (i.e. ring and pinky fingers) then the feeling comes back and the back of my lower arm is numb, then my upper arm then all of a sudden my cheek and then my nose. This is the most bizarre symptom I've ever had and I always think I'm having a stroke! I have been assured by my GP and my Ophthalmologist that this truly is one more symptom of an aura migraine. Still so odd...
