@dablues You should have been told yrs. ago . I was told as soon as my pressures where high . Dr. put me on Latanoprost eye drops at night. I also have macular degeneration. I will say when I was much younger they treated me for suspicious glaucoma but my pressures where always within limits then a Dr took of the meds to see if I really had glaucoma or not I didn't have any irregular pressure readings for almost 40 yrs then all of a sudden my pressures went to over 20 in both eyes this is when she put me on drops . But yes you should have been told at that point . I wasn't on anything when I had my cararacts out this started only 5 yrs ago. Good luck .
