Miki - Now that you have got the IOP down to 18, why not give N-Acetyl CarnoSine a try: 'CanCee' is the product in the the USA, and in the UK 'Bright Eyes'. I have been using for a year, and is doing the trick for me. Keeping IOP way down. Can but try. But for heaven's sake, IF it don't work for *you then MUST go a different route pdq. OK?
