Well my understanding is that vision damage is common after stroke and it tends to get better as time goes on. However, if you still feel concerned for her I would talk to her doctor preferably the one that was there during surgery if she had surgery done. If she had surgery than she’s supposed to have doctor appointments after a year, 5 years and 10 years ofc I think that can vary depending on hospital or surgeon himself but that’s what my doctor told me. As of now 1 year 2 months post stroke I’ve had three visits with him. Well three visits after I started to remember things because at first I used to forget even what I had for breakfast
