I've progressed to 2 different eye drops for about a year now and my eye pressure is finally stable at around 20 in each eye. After extensive testing they determined that the increased pressure was discovered and treated soon enough that there was no damage to my eyes and my vision hasn't suffered. As a photographer I'm acutely aware of my eye health (not much market for blind photographers) and did a little research into 'alternative' treatments and preventatives. From what I read the cannabis approach doesn't seem to offer much reduction in the pressure although I suppose you could make the argument that using it would cause you to relax thus reducing your stress and blood pressure which could help with the eye pressure...

My opthomologist said that there are one or two other drops we could move to if the current drops become ineffective. After that the options are laser surgery to open the 'holes' where the eye fluid naturally drains. On that line of thought, my mother in law has much better insurance (PPO) and she was able to bypass the progression of drops and went straight to the surgery.

I asked my optho if exercise and general healthy living had any effect on eye pressure and he said not much. That part didn't make much sense to me but that was his view.
