But the speculation does not stop there. These same doctors speculate that the pituitary tumor grew to impinge upon the [[optic chiasm]] and cut off the signals that pass from each [[eye]] to the opposing [[occipital lobe]], which is the center for visual processing. Thus Goliath would have suffered [[bitemporal hemianopsia]], which produces "tunnel vision," and thus David would have been better able to approach him close enough to deliver a killing blow with his slingshot.<ref>Berginer, Vladimir M.
