Are Vision and Consciousness Intimately Related?

In my article on brain waves and consciousness I looked at some research associating gamma wave activity with consciousness. This is, however, a controversial area in that other researchers have found that such gamma activity is also correlated with eye movements known as saccades: these are the small eye movements that the brain edits out so that we do not perceive the world as a blur as we switch focus. So, are brain gamma waves merely a byproduct of saccadic movements or are they correlated with consciousness or, potentially, both?
