I can relay to you what members of my late husband's family including my DD have done with this.
They have a genetic strain of glaucoma in the family, and my oldest DD was diagnosed as pre-glaucoma 4 years ago.
The family members that contract it typically were in their 30's and 40's which is young for it. All of them chose to go the route of drops first, then some eventually went to laser surgery including my late FIL. He had the maximum amount of laser surgeries that they could do and was not seeing well at the end of his life at all.
My BIL had drops for about a couple of years when he was 30 or so and then had a laser treatment. He is doing very well now.
My DD is on stringent care with the eye specialists and they run batteries of tests on her every 6 months. She is not on glaucoma meds at this time though she does take Hydro Eye and Restasis. She has been stable and has not worsened so we have been encouraged. She is 25 and a high school English teacher. She relies on her eyes so much (as we all do) and I have been so worried about her vision. Thankfully, she is doing well now though.
Good luck to you and keep us posted!
