Is this always one half of your field of view? Or is it one half of certain objects (e.g. your face)? If it's the first, then it sounds like damage to one visual pathway. The visual input from each eye is divided into left and right fields, and they're processed independently. Here's a good illustration: http://commons.wikimedia.org/wiki/File:Constudeyepath.gif#mediaviewer/File:Constudeyepath.gif http://commons.wikimedia.org/wiki/File:Constudeyepath.gif#me... After the optic chiasma, the two pathways diverge. Damage any time after there, such as to the occipital lobe of one hemisphere, could result in blindness to one half of the field of view.
