I was diagnosed with glaucoma over 30 years ago. I'm now 79. They had trouble keeping my pressure within range 12-15. I'm now on 3 eye drops: Pilocarpine, Dorzolimide, and Rocklatan which works to keep pressure in range. I have field test at least once a year. I've now lost all central vision in left eye and I only have about 50% of field left in right eye. So I have low vision with lots of glare problems. I see an optimologist who trained at Bascom Palmer Eye Institute in Miami, and I go there every 5 years to see if anything new is recommended. I highly recommend you go to one of the top eye research centers for a second opinion if you have any questions.
