Hello Don, did you have a shunt? I got glaucoma after a detached retina and I've only had it 10 months but my pressure is up to 50. I declined an operation last week due to lack of information and indecision. I'm reading about people who keep the pressure down to 20 or so for 20 years without an op. I wouldn't mind that. I'm not looking forward to ops, especially because there's little vision in that eye.
