  1. Yes.

    The part of the brain that interprets signals sent by the optic nerve is, oddly enough, at the back of your head.  A stroke involving the posterior cerebral artery can damage this area and cause what is called cortical blindness (meaning that the eye works but the brain can no longer receive its signals).

    Depending on how much of the visual cortex is damaged, you can get incomplete blindness (hemianopia) or "macular sparing"--you can still see centrally although peripheral vision is gone.

    People with this kind of damage still have reactive pupils, because the nerves in the eye that control them are undamaged.  Some of them also have an unusual condition called Anton syndrome, where they do not realize they are blind, or even more oddly, can identify moving but not stationary objects--the Riddoch phenomenon.

    Neurology covers some odd stuff.  ;-)


  2. Vision loss can be a result of a stoke. I've found a site which may answer any questions you have about vision relation to stroke.
