Patient's question:
My mother lost her eyesight after undergoing brain tumor surgery in 1992, and it has been over ten years since then. Her eyes are normal, but it might be an issue with the optic nerves. I wonder if there are any tests that can determine whether she can regain her sight! Please advise, so that my hair-graying mother can once again see the beautiful world!Doctor's answer:
It's impossible for anyone to be certain.
