@wantingtoknow Hi Lioness here Im 76 now I tell you this as in my 30,s I was told I had narrow open glucoma the Dr put me on drops My pressure was always good like yours ,then after several years on the Timoptic drops he took me of as my pressure stayed the same About a year ago my pressure for the first time was 20/24 Dr gave me drops a year later my pressure was back in the teens again ,she told me I could go of or stay on???? If I remember I,ll use the drops but at my age I have macular degeneration now. I would suggest you go for another opinion and see what the Dr says This is just what happened to me. Good luck.
