Seeing a grid in the morning

I do not know where else to find information on this "vision-issue".
On some mornings, I wake up and for a minute or two, I see a grid of
intersecting lines which fills my field of vision, whether my eyes are
opened or closed. Then it goes away.

My only concern is that I once saw a special on tv about a boy who was
seeing lines and it turns out he had a growth inside of his brain.
I do not want it to be such a case and I usually chalk it up to sinus
pressure.

Has anyone heard or read about seeing intersecting lines in the
morning?
Thanks.

 

Yeah, I get that, too. My eye doc said it was shadows from an overley
engorged blood vessels in the retina when waking up, or something like that.
He wasn't concerned and knew of the phenomena.

You should probably go get it checked out, though, just to be sure.

Thanks,

Ok, doesnt sound so bad.

 

Still get it checked out, though.

Thanks,

Mike
