IOP effects of roller coaster? bungee jumping? skydiving?

Any thoughts on the safety (IOP-wise) of riding a roller coaster, or bungee jumping, or sky diving?  I've been googling but so far have only come across relatively anecdotal comments, such as this: www.willsglaucoma.org/supportgroup/chat06072000.html

Some of the newer roller coasters pull significant g's (and look quite fun!), but I'm wondering if that could raise IOP's to a dangerous level.  Either from the direct physical g force, or from the adrenalin rush (excitement) of riding the roller coaster...?
