Here is a recent thread on Fiteyes newsgroup
I have been doing self-tonometry every day for the past 8 months or so with the Reichert 7 cr. I have experimented with different types of exercise, both aerobic and weigh bearing, meditation, visualization, deep breathing, etc. It seems getting my IOP lowered through any of these measures is hit or miss. Sometimes my pressure winds up going higher, even when I am feeling completely relaxed and peaceful.
