rolfing

I came across an article about rolfing which makes it sound quite useful/healthy.

Ref:www.nytimes.com/2010/10/07/fashion/07rolfing.html

But the pain issue makes me suspicious that it may increase IOP.  Has anyone measured their IOP before/during/after rolfing?   And if you have and the results were positive, do you have any recommendations for those of us who have not rolfed?  Eg, are there any precautions, techniques to avoid, or techniques to request?
