I can relate directly. I was age 25 when I was diagnosed with intraocular hypertension by my regular ophthalmologist. My numbers were about 25 or 26. I was sent to Columbia Presbyterian Hospital in NYC to be seen by a specialist and was put through over 4 hours of testing, including the drinking of a gallon of water in an hour to see if the pressures went up (they did not). I was sent home with the admonition to have my pressures checked quarterly, but I was put on no medicine. Needless to say, I was convinced I would be blind by age 50.
Fast forward to today and I am now 61 years old and have full vision. My pressures have gone up to about 27 or 28 and I have them checked annually. I am on no medicine.
Now, here is the important part. It was not until about 10 years ago that I found a new ophthalmologist due to a move. He was the first doctor to measure my corneas and found them to be extremely thick. The device used to test for intraocular pressures is calibrated for "normal" corneas. Those with thick corneas register high readings when, in fact, the pressures are normal, since the device does not "correct" for thick corneas. My sister has the exact same problem and is being followed by a different doctor. We both have thick corneas and above normal pressure readings, but our eyes are fine.
So, first, check with your doctor to make sure you do not have thick corneas. If your corneas are normal, then follow the advice of your doctor. The good news is that high eye pressures are treatable and do not mean eventual blindness. Good luck to you.
