Question 5
A basketball player was rushed to the ER after falling on his backside while attempting to
dunk a basketball. He broke the fall with the posterior portion of his head. He now has
cortical blindness. What does this mean?
? The damage to the visual cortex in the occipital lobe was so great that he is now blind.
? The retinal photoreceptors were replaced with scar tissue from the damage to retinal blood tissue.
? The retina was deprived of oxygen too long, and consequently the cells died and cannot regenerate.
? He was given too much oxygen in the ER at first, which constricted blood vessels in the retina and
thus the retina cells died.
