Well that really depends on how fast they get medical treatment and other circumstances, but I'm no doctor so I only know what I was told by that crazy israeli guy.barbzilla said:Getting an infection on the nerve cluster behind the eye that leads directly to the cortex of the brain, will likely lead to death, thus the manslaughter cases I was talking about. There is a very real risk when applying maneuvers such as these, and why they are only meant to be used in life or death situations (as it may save your life at the cost of your assailant's, which isn't necessarily bad, just messy).
Of course there is a risk when using harmful maneuvers like this, but if there is someone trying to kill you or rape you, which is what the women in the courses are mostly afraid of, or both, than you should deal with one problem after another. First eliminate the attacker, than deal with the possible repercussions, if you hold back you might give up the slight edge that would have saved your hide.
