I feel my eyesight is a little different since chemo but I have waited for testing as wanted to give my body a chance for full cell recovery following chemo.
Glaucoma is a progressive disease for many people and this may have happened regardless of treatment . We often do blame medication /treatment for things that may have just happened as part of ageing, normal disease processes. Drs are often reluctant to say no its not anything to do with that just in case it is, even though they might have mentally dismissed it.
I hope your treatment works well. Kath x
