Inversion Therapy - Glaucoma - Any thoughts!

On my second visit to the osteopath he placed me on an inversion table. I told him that I have glaucoma and every search on this topic has come up witha warning "if you have pressure do not use inversion table".

I am a bit confused as I read in Dr. Christopher's writing that a slant board should be used for glaucoma besides the eyebright herb, B&B etc.

The more I read about inversion therapy the more I like it but I am afraid to let the osteopath talk me into this.

Would very much appreciate any thoughts on this....

Thank you.
