glaucoma, open angle
"Have had glaucoma since I was 30.  I am now 76 with little optic nerve damage.  This is one of two glaucoma drugs I take--latanoprost is the other.  Have been on both for over 15 years (including the brand names before those two generics).  This drug initially stung but got better as the years passed.  I thank them for helping me keep my sight.  I am also very lucky and have received excellent medical care as well as an early diagnosis."
