David & Goliath

Skeptics of Face off between David & Goliath

J.R. Grifffin & Vladimir M Berliner. Argue that this struggle outcome was foreordained.

Claim of What Happened

Goliath’s sight was seriously impaired, which would have made him a pushover for David. If Griffin correct, the fight was fixed and unfair in David’s favor.

Visual system produced a corresponding, specific visual loss

If optic nerve from the right eye were severely damaged, there would be no vision from that eye. Geometry of visual system makes for some more complex relationships.

Visual Field Measurements

Can identify the locus of damage

Ex of Measurements for Visual Field

Tumors of the pituitary gland can press on nerve fibers in optic chains so that a patient becomes blind in half the viusal field

Bi-Temporal Hemjanopia

Blindness affects the visual field toward the temple in each eye

How could Goliath have a tumor?

Griffin & Berginer speculated that Goliath big stature was symptomatic of gigantism, an endocrine disorder. Gigantism is associated with a tumor of pituitary gland. Goliath has pituitary tumor, probable resulting from hypersecretion of growth hormone starting in his childhood

What can a fully developed liturgy tumor do optic chaism

Can press on optic chiasm. Where 50% of retinal ganglion cell axons from each eye cross over to other side of body on their way to the brain
